+### Overview
+Pageserver and proxy periodically collect consumption metrics and push them to a HTTP endpoint.
+
+This doc describes current implementation details.
+For design details see [the RFC](./rfcs/021-metering.md) and [the discussion on Github](https://github.com/neondatabase/neon/pull/2884).
+
+- The metrics are collected in a separate thread, and the collection interval and endpoint are configurable.
+
+- Metrics are cached, so that we don't send unchanged metrics on every iteration.
+
+- Metrics are sent in batches of 1000 (see CHUNK_SIZE const) metrics max with no particular grouping guarantees.
+
+batch format is
+```json
+
+{ "events" : [metric1, metric2, ...]]}
+
+```
+See metric format examples below.
+
+- All metrics values are in bytes, unless otherwise specified.
+
+- Currently no retries are implemented.
+
+### Pageserver metrics
+
+#### Configuration
+The endpoint and the collection interval are specified in the pageserver config file (or can be passed as command line arguments):
+`metric_collection_endpoint` defaults to None, which means that metric collection is disabled by default.
+`metric_collection_interval` defaults to 10min
+
+#### Metrics
+
+Currently, the following metrics are collected:
+
+- `written_size`
+
+Amount of WAL produced , by a timeline, i.e. last_record_lsn
+This is an absolute, per-timeline metric.
+
+- `resident_size`
+
+Size of all the layer files in the tenant's directory on disk on the pageserver.
+This is an absolute, per-tenant metric.
+
+- `remote_storage_size`
+
+Size of the remote storage (S3) directory.
+This is an absolute, per-tenant metric.
+
+- `timeline_logical_size`
+Logical size of the data in the timeline
+This is an absolute, per-timeline metric.
+
+- `synthetic_storage_size`
+Size of all tenant's branches including WAL
+This is the same metric that `tenant/{tenant_id}/size` endpoint returns.
+This is an absolute, per-tenant metric.
+
+Synthetic storage size is calculated in a separate thread, so it might be slightly outdated.
+
+#### Format example
+
+```json
+{
+"metric": "remote_storage_size",
+"type": "absolute",
+"time": "2022-12-28T11:07:19.317310284Z",
+"idempotency_key": "2022-12-28 11:07:19.317310324 UTC-1-4019",
+"value": 12345454,
+"tenant_id": "5d07d9ce9237c4cd845ea7918c0afa7d",
+"timeline_id": "a03ebb4f5922a1c56ff7485cc8854143",
+}
+```
+
+`idempotency_key` is a unique key for each metric, so that we can deduplicate metrics.
+It is a combination of the time, node_id and a random number.
+
+### Proxy consumption metrics
+
+#### Configuration
+The endpoint and the collection interval can be passed as command line arguments for proxy:
+`metric_collection_endpoint` no default, which means that metric collection is disabled by default.
+`metric_collection_interval` no default
+
+#### Metrics
+
+Currently, only one proxy metric is collected:
+
+- `proxy_io_bytes_per_client`
+Outbound traffic per client.
+This is an incremental, per-endpoint metric.
+
+#### Format example
+
+```json
+{
+"metric": "proxy_io_bytes_per_client",
+"type": "incremental",
+"start_time": "2022-12-28T11:07:19.317310284Z",
+"stop_time": "2022-12-28T11:07:19.317310284Z",
+"idempotency_key": "2022-12-28 11:07:19.317310324 UTC-1-4019",
+"value": 12345454,
+"endpoint_id": "5d07d9ce9237c4cd845ea7918c0afa7d",
+}
+```
+
+The metric is incremental, so the value is the difference between the current and the previous value.
+If there is no previous value, the value, the value is the current value and the `start_time` equals `stop_time`.
+
+### TODO
+
+- [ ] Handle errors better: currently if one tenant fails to gather metrics, the whole iteration fails and metrics are not sent for any tenant.
+- [ ] Add retries
+- [ ] Tune the interval

+# Consumption tracking
+
+
+# Goals
+
+This proposal is made with two mostly but not entirely overlapping goals:
+
+* Collect info that is needed for consumption-based billing
+* Cross-check AWS bills
+
+
+# Metrics
+
+There are six metrics to collect:
+
+* CPU time. Wall clock seconds * the current number of cores. We have a fixed ratio of memory to cores, so the current memory size is the function of the number of cores. Measured per each `endpoint`.
+
+* Traffic. In/out traffic on the proxy. Measured per each `endpoint`.
+
+* Written size. Amount of data we write. That is different from both traffic and storage size, as only during the writing we
+
+  a) occupy some disk bandwidth on safekeepers
+
+  b) necessarily cross AZ boundaries delivering WAL to all safekeepers
+
+  Each timeline/branch has at most one writer, so the data is collected per branch.
+
+* Synthetic storage size. That is what is exposed now with pageserver's `/v1/tenant/{}/size`. Looks like now it is per-tenant. (Side note: can we make it per branch to show as branch physical size in UI?)
+
+* Real storage size. That is the size of the tenant directory on the pageservers disk. Per-tenant.
+
+* S3 storage size. That is the size of the tenant data on S3. Per-tenant.
+
+That info should be enough to build an internal model that predicts AWS price (hence tracking `written data` and `real storage size`). As for the billing model we probably can get away with mentioning only `CPU time`, `synthetic storage size`, and `traffic` consumption.
+
+# Services participating in metrics collection
+
+## Proxy
+
+For actual implementation details check `/docs/consumption_metrics.md`
+
+Proxy is the only place that knows about traffic flow, so it tracks it and reports it with quite a small interval, let's say 1 minute. A small interval is needed here since the proxy is stateless, and any restart will reset accumulated consumption. Also proxy should report deltas since the last report, not an absolute value of the counter. Such kind of events is easier to integrate over a period of time to get the amount of traffic during some time interval.
+
+Example event:
+
+```json
+{
+"metric": "proxy_io_bytes_per_client",
+"type": "incremental",
+"start_time": "2022-12-28T11:07:19.317310284Z",
+"stop_time": "2022-12-28T11:07:19.317310284Z",
+"idempotency_key": "2022-12-28 11:07:19.317310324 UTC-1-4019",
+"value": 12345454,
+"endpoint_id": "5d07d9ce9237c4cd845ea7918c0afa7d",
+}
+```
+
+Since we report deltas over some period of time, it makes sense to include `event_start_time`/`event_stop_time` where `event_start_time` is the time of the previous report. That will allow us to identify metering gaps better (e.g., failed send/delivery).
+
+When there is no active connection proxy can avoid reporting anything. Also, deltas are additive, so several console instances serving the same user and endpoint can report traffic without coordination.
+
+## Console
+
+The console knows about start/stop events, so it knows the amount of CPU time allocated to each endpoint. It also knows about operation successes and failures and can avoid billing clients after unsuccessful 'suspend' events. The console doesn't know the current compute size within the allowed limits on the endpoint. So with CPU time, we do the following:
+
+* While we don't yet have the autoscaling console can report `cpu time` as the number of seconds since the last `start_compute` event.
+
+* When we have autoscaling, `autoscaler-agent` can report `cpu time`*`compute_units_count` in the same increments as the proxy reports traffic.
+
+Example event:
+
+```json
+{
+    "metric": "effective_compute_seconds",
+    "type": "increment",
+    "endpoint_id": "blazing-warrior-34",
+    "event_start_time": ...,
+    "event_stop_time": ...,
+    "value": 12345454,
+}
+```
+
+I'd also suggest reporting one value, `cpu time`*`compute_units_count`, instead of two separate fields as it makes event schema simpler (it is possible to treat it the same way as traffic) and preserves additivity.
+
+## Pageserver
+
+For actual implementation details check `/docs/consumption_metrics.md`
+
+Pageserver knows / has access to / can calculate the rest of the metrics:
+
+* Written size -- that is basically `last_received_lsn`,
+* Synthetic storage size -- there is a way to calculate it, albeit a costly one,
+* Real storage size -- there is a way to calculate it using a layer map or filesystem,
+* S3 storage size -- can calculate it by S3 API calls
+
+Some of those metrics are expensive to calculate, so the reporting period here is driven mainly by implementation details. We can set it to, for example, once per hour. Not a big deal since the pageserver is stateful, and all metrics can be reported as an absolute value, not increments. At the same time, a smaller reporting period improves UX, so it would be good to have something more real-time.
+
+`written size` is primarily a safekeeper-related metric, but since it is available on both pageserver and safekeeper, we can avoid reporting anything from the safekeeper.
+
+Example event:
+
+```json
+{
+"metric": "remote_storage_size",
+"type": "absolute",
+"time": "2022-12-28T11:07:19.317310284Z",
+"idempotency_key": "2022-12-28 11:07:19.317310324 UTC-1-4019",
+"value": 12345454,
+"tenant_id": "5d07d9ce9237c4cd845ea7918c0afa7d",
+"timeline_id": "a03ebb4f5922a1c56ff7485cc8854143",
+}
+```
+
+# Data collection
+
+## Push vs. pull
+
+We already have pull-based Prometheus metrics, so it is tempting to use them here too. However, in our setup, it is hard to tell when some metric changes. For example, garbage collection will constantly free some disk space over a week, even if the project is down for that week. We could also iterate through all existing tenants/branches/endpoints, but that means some amount of code to do that properly and most likely we will end up with some per-metric hacks in the collector to cut out some of the tenants that are surely not changing that metric.
+
+With the push model, it is easier to publish data only about actively changing metrics -- pageserver knows when it performs s3 offloads, garbage collection and starts/stops consuming data from the safekeeper; proxy knows about connected clients; console / autoscaler-agent knows about active cpu time.
+
+Hence, let's go with a push-based model.
+
+## Common bus vs. proxying through the console
+
+We can implement such push systems in a few ways:
+
+a. Each component pushes its metrics to the "common bus", namely segment, Kafka, or something similar. That approach scales well, but it would be harder to test it locally, will introduce new dependencies, we will have to distribute secrets for that connection to all of the components, etc. We would also have to loop back some of the events and their aggregates to the console, as we want to show some that metrics to the user in real-time.
+
+b. Each component can call HTTP `POST` with its events to the console, and the console can forward it to the segment for later integration with metronome / orb / onebill / etc. With that approach, only the console has to speak with segment. Also since that data passes through the console, the console can save the latest metrics values, so there is no need for constant feedback of that events back from the segment.
+
+# Implementation
+
+Each (proxy|pageserver|autoscaler-agent) sends consumption events to the single endpoint in the console:
+
+```json
+POST /usage_events HTTP/1.1
+Content-Type: application/json
+
+[
+{
+"metric": "remote_storage_size",
+"type": "absolute",
+"time": "2022-12-28T11:07:19.317310284Z",
+"idempotency_key": "2022-12-28 11:07:19.317310324 UTC-1-4019",
+"value": 12345454,
+"tenant_id": "5d07d9ce9237c4cd845ea7918c0afa7d",
+"timeline_id": "a03ebb4f5922a1c56ff7485cc8854143",
+},
+...
+]
+```
+
+![data flow](./images/metering.jpg)
+
+Events could be either:
+* `incremental` -- change in consumption since the previous event or service restart. That is `effective_cpu_seconds`, `traffic_in_bytes`, and `traffic_out_bytes`.
+* `absolute` -- that is the current value of a metric. All of the size-related metrics are absolute.
+
+Each service can post events at its own pace and bundle together data from different tenants/endpoints.
+
+The console algorithm upon receive of events could be the following:
+
+1. Create and send a segment event with the same content (possibly enriching it with tenant/timeline data for endpoint-based events).
+2. Update the latest state of per-tenant and per-endpoint metrics in the database.
+3. Check whether any of that metrics is above the allowed threshold and stop the project if necessary.
+
+Since all the data comes in batches, we can do the batch update to reduce the number of queries in the database. Proxy traffic is probably the most frequent metric, so with batching, we will have extra `number_of_proxies` requests to the database each minute. This is most likely fine for now but will generate many dead tuples in the console database. If that is the case, we can change step 2 to the following:
+
+2.1. Check if there $tenant_$metric / $endpoint_$metric key in Redis
+
+2.2. If no stored value is found and the metric is incremental, then fetch the current value from DWH (which keeps aggregated value for all the events) and publish it.
+
+2.3. Publish a new value (absolute metric) or add an increment to the stored value (incremental metric)
+
+## Consumption watchdog
+
+Since all the data goes through the console, we don't have to run any background thread/coroutines to check whether consumption is within the allowed limits. We only change consumption with `POST /usage_events`, so limit checks could be applied in the same handler.
+
+## Extensibility
+
+If we need to add a new metric (e.g. s3 traffic or something else), the console code should, by default, process it and publish segment event, even if the metric name is unknown to the console.
+
+## Naming & schema
+
+Each metric name should end up with units -- now `_seconds` and `_bytes`, and segment event should always have `tenant_id` and `timeline_id`/`endpoint_id` where applicable.

+# Synthetic size
+
+Neon storage has copy-on-write branching, which makes it difficult to
+answer the question "how large is my database"? To give one reasonable
+answer, we calculate _synthetic size_ for a project.
+
+The calculation is called "synthetic", because it is based purely on
+the user-visible logical size, which is the size that you would see on
+a standalone PostgreSQL installation, and the amount of WAL, which is
+also the same as what you'd see on a standalone PostgreSQL, for the
+same set of updates.
+
+The synthetic size does *not* depend on the actual physical size
+consumed in the storage, or implementation details of the Neon storage
+like garbage collection, compaction and compression.  There is a
+strong *correlation* between the physical size and the synthetic size,
+but the synthetic size is designed to be independent of the
+implementation details, so that any improvements we make in the
+storage system simply reduce our COGS. And vice versa: any bugs or bad
+implementation where we keep more data than we would need to, do not
+change the synthetic size or incur any costs to the user.
+
+The synthetic size is calculated for the whole project. It is not
+straighforward to attribute size to individual branches. See "What is
+the size of an individual branch?" for discussion on those
+difficulties.
+
+The synthetic size is designed to:
+
+- Take into account the copy-on-write nature of the storage. For
+  example, if you create a branch, it doesn't immediately add anything
+  to the synthetic size. It starts to affect the synthetic size only
+  as it diverges from the parent branch.
+
+- Be independent of any implementation details of the storage, like
+  garbage collection, remote storage, or compression.
+
+## Terms & assumptions
+
+- logical size is the size of a branch *at a given point in
+  time*. It's the total size of all tables in all databases, as you
+  see with "\l+" in psql for example, plus the Postgres SLRUs and some
+  small amount of metadata. NOTE that currently, Neon does not include
+  the SLRUs and metadata in the logical size. See comment to `get_current_logical_size_non_incremental()`.
+
+- a "point in time" is defined as an LSN value. You can convert a
+  timestamp to an LSN, but the storage internally works with LSNs.
+
+- PITR horizon can be set per-branch.
+
+- PITR horizon can be set as a time interval, e.g. 5 days or hours, or
+  as amount of WAL, in bytes.  If it's given as a time interval, it's
+  converted to an LSN for the calculation.
+
+- PITR horizon can be set to 0, if you don't want to retain any history.
+
+## Calculation
+
+Inputs to the calculation are:
+- logical size of the database at different points in time,
+- amount of WAL generated, and
+- the PITR horizon settings
+
+The synthetic size is based on an idealistic model of the storage
+system, where we pretend that the storage consists of two things:
+- snapshots, containing a full snapshot of the database, at a given
+  point in time, and
+- WAL.
+
+In the simple case that the project contains just one branch (main),
+and a fixed PITR horizon, the synthetic size is the sum of:
+
+- the logical size of the branch *at the beginning of the PITR
+  horizon*, i.e. at the oldest point that you can still recover to, and
+- the size of the WAL covering the PITR horizon.
+
+The snapshot allows you to recover to the beginning of the PITR
+horizon, and the WAL allows you to recover from that point to any
+point within the horizon.
+
+```
+                             WAL
+   -----------------------#########>
+                          ^
+                       snapshot
+
+Legend:
+  ##### PITR horizon. This is the region that you can still access
+        with Point-in-time query and you can still create branches
+        from.
+  ----- history that has fallen out of the PITR horizon, and can no
+        longer be accessed
+```
+
+NOTE: This is not how the storage system actually works! The actual
+implementation is also based on snapshots and WAL, but the snapshots
+are taken for individual database pages and ranges of pages rather
+than the whole database, and it is much more complicated. This model
+is a reasonable approximation, however, to make the synthetic size a
+useful proxy for the actual storage consumption.
+
+
+## Example: Data is INSERTed
+
+For example, let's assume that your database contained 10 GB of data
+at the beginning of the PITR horizon, and you have since then inserted
+5 GB of additional data into it. The additional insertions of 5 GB of
+data consume roughly 5 GB of WAL. In that case, the synthetic size is:
+
+> 10 GB (snapshot) +  5 GB (WAL) = 15 GB
+
+If you now set the PITR horizon on the project to 0, so that no
+historical data is retained, then the beginning PITR horizon would be
+at the end of the branch, so the size of the snapshot would be
+calculated at the end of the branch, after the insertions. Then the
+synthetic size is:
+
+> 15 GB (snapshot) + 0 GB (WAL) = 15 GB.
+
+In this case, the synthetic size is the same, regardless of the PITR horizon,
+because all the history consists of inserts. The newly inserted data takes
+up the same amount of space, whether it's stored as part of the logical
+snapshot, or as WAL. (*)
+
+(*) This is a rough approximation. In reality, the WAL contains
+headers and other overhead, and on the other hand, the logical
+snapshot includes empty space on pages, so the size of insertions in
+WAL can be smaller or greater than the size of the final table after
+the insertions. But in most cases, it's in the same ballpark.
+
+## Example: Data is DELETEd
+
+Let's look at another example:
+
+Let's start again with a database that contains 10 GB of data. Then,
+you DELETE 5 GB of the data, and run VACUUM to free up the space, so
+that the logical size of the database is now only 5 GB.
+
+Let's assume that the WAL for the deletions and the vacuum take up
+100 MB of space. In that case, the synthetic size of the project is:
+
+> 10 GB (snapshot) + 100 MB (WAL) = 10.1 GB
+
+This is much larger than the logical size of the database after the
+deletions (5 GB). That's because the system still needs to retain the
+deleted data, because it's still accessible to queries and branching
+in the PITR window.
+
+If you now set the PITR horizon to 0 or just wait for time to pass so
+that the data falls out of the PITR horizon, making the deleted data
+inaccessible, the synthetic size shrinks:
+
+> 5 GB (snapshot) + 0 GB (WAL) = 5 GB
+
+
+# Branching
+
+Things get more complicated with branching. Branches in Neon are
+copy-on-write, which is also reflected in the synthetic size.
+
+When you create a branch, it doesn't immediately change the synthetic
+size at all. The branch point is within the PITR horizon, and all the
+data needed to recover to that point in time needs to be retained
+anyway.
+
+However, if you make modifications on the branch, the system needs to
+keep the WAL of those modifications. The WAL is included in the
+synthetic size.
+
+## Example: branch and INSERT
+
+Let's assume that you again start with a 10 GB database.
+On the main branch, you insert 2 GB of data. Then you create
+a branch at that point, and insert another 3 GB of data on the
+main branch, and 1 GB of data on the child branch
+
+```
+  child                 +#####>
+                        |
+                        |    WAL
+  main    ---------###############>
+                   ^
+                snapshot
+```
+
+In this case, the synthetic size consists of:
+- the snapshot at the beginning of the PITR horizon (10 GB)
+- the WAL on the main branch (2 GB + 3 GB = 5 GB)
+- the WAL on the child branch (1 GB)
+
+Total: 16 GB
+
+# Diverging branches
+
+If there is only a small amount of changes in the database on the
+different branches, as in the previous example, the synthetic size
+consists of a snapshot before the branch point, containing all the
+shared data, and the WAL on both branches. However, if the branches
+diverge a lot, it is more efficient to store a separate snapshot of
+branches.
+
+## Example: diverging branches
+
+You start with a 10 GB database. You insert 5 GB of data on the main
+branch. Then you create a branch, and immediately delete all the data
+on the child branch and insert 5 GB of new data to it. Then you do the
+same on the main branch. Let's assume
+that the PITR horizon requires keeping the last 1 GB of WAL on the
+both branches.
+
+```
+                              snapshot
+                                  v     WAL
+  child                 +---------##############>
+                        |
+                        |
+  main     -------------+---------##############>
+                                  ^     WAL
+                              snapshot
+```
+
+In this case, the synthetic size consists of:
+- snapshot at the beginning of the PITR horizon on the main branch (4 GB)
+- WAL on the main branch (1 GB)
+- snapshot at the beginning of the PITR horizon on the child branch (4 GB)
+- last 1 GB of WAL on the child branch (1 GB)
+
+Total: 10 GB
+
+The alternative way to store this would be to take only one snapshot
+at the beginning of branch point, and keep all the WAL on both
+branches.  However, the size with that method would be larger, as it
+would require one 10 GB snapshot, and 5 GB + 5 GB of WAL. It depends
+on the amount of changes (WAL) on both branches, and the logical size
+at the branch point, which method would result in a smaller synthetic
+size. On each branch point, the system performs the calculation with
+both methods, and uses the method that is cheaper, i.e. the one that
+results in a smaller synthetic size.
+
+One way to think about this is that when you create a branch, it
+starts out as a thin branch that only stores the WAL since the branch
+point.  As you modify it, and the amount of WAL grows, at some point
+it becomes cheaper to store a completely new snapshot of the branch
+and truncate the WAL.
+
+
+# What is the size of an individual branch?
+
+Synthetic size is calculated for the whole project, and includes all
+branches. There is no such thing as the size of a branch, because it
+is not straighforward to attribute the parts of size to individual
+branches.
+
+## Example: attributing size to branches
+
+(copied from https://github.com/neondatabase/neon/pull/2884#discussion_r1029365278)
+
+Imagine that you create two branches, A and B, at the same point from
+main branch, and do a couple of small updates on both branches. Then
+six months pass, and during those six months the data on the main
+branch churns over completely multiple times. The retention period is,
+say 1 month.
+
+```
+                      +------> A
+                     /
+--------------------*-------------------------------> main
+                     \
+                      +--------> B
+```
+
+In that situation, the synthetic tenant size would be calculated based
+on a "logical snapshot" at the branch point, that is, the logical size
+of the database at that point. Plus the WAL on branches A and B. Let's
+say that the snapshot size is 10 GB, and the WAL is 1 MB on both
+branches A and B. So the total synthetic storage size is 10002
+MB. (Let's ignore the main branch for now, that would be just added to
+the sum)
+
+How would you break that down per branch? I can think of three
+different ways to do it, and all of them have their own problems:
+
+### Subtraction method
+
+For each branch, calculate how much smaller the total synthetic size
+would be, if that branch didn't exist. In other words, how much would
+you save if you dropped the branch. With this method, the size of
+branches A and B is 1 MB.
+
+With this method, the 10 GB shared logical snapshot is not included
+for A nor B. So the size of all branches is not equal to the total
+synthetic size of the tenant. If you drop branch A, you save 1 MB as
+you'd expect, but also the size of B suddenly jumps from 1 MB to 10001
+MB, which might feel surprising.
+
+### Division method
+
+Divide the common parts evenly across all branches that need
+them. With this method, the size of branches A and B would be 5001 MB.
+
+With this method, the sum of all branches adds up to the total
+synthetic size. But it's surprising in other ways: if you drop branch
+A, you might think that you save 5001 MB, but in reality you only save
+1 MB, and the size of branch B suddenly grows from 5001 to 10001 MB.
+
+### Addition method
+
+For each branch, include all the snapshots and WAL that it depends on,
+even if some of them are shared by other branches. With this method,
+the size of branches A and B would be 10001 MB.
+
+The surprise with this method is that the sum of all the branches is
+larger than the total synthetic size. And if you drop branch A, the
+total synthetic size doesn't fall by 10001 MB as you might think.
+
+# Alternatives
+
+A sort of cop-out method would be to show the whole tree of branches
+graphically, and for each section of WAL or logical snapshot, display
+the size of that section. You can then see which branches depend on
+which sections, which sections are shared etc. That would be good to
+have in the UI anyway.
+
+Or perhaps calculate per-branch numbers using the subtraction method,
+and in addition to that, one more number for "shared size" that
+includes all the data that is needed by more than one branch.
+
+## Which is the right method?
+
+The bottom line is that it's not straightforward to attribute the
+synthetic size to individual branches. There are things we can do, and
+all of those methods are pretty straightforward to implement, but they
+all have their own problems. What makes sense depends a lot on what
+you want to do with the number, what question you are trying to
+answer.
