# Grafana dashboards for GreptimeDB
|
||||
Grafana dashboard for GreptimeDB
|
||||
--------------------------------
|
||||
|
||||
## Overview
|
||||
GreptimeDB's official Grafana dashboard.
|
||||
|
||||
This repository maintains the Grafana dashboards for GreptimeDB. It has two types of dashboards:
|
||||
Status notify: we are still working on this config. It's expected to change frequently in the recent days. Please feel free to submit your feedback and/or contribution to this dashboard 🤗
|
||||
|
||||
- `cluster/`: The dashboard for the GreptimeDB cluster. Read the [dashboard.md](./dashboards/cluster/dashboard.md) for more details.
|
||||
- `standalone/`: The dashboard for the standalone GreptimeDB instance. Read the [dashboard.md](./dashboards/standalone/dashboard.md) for more details.
|
||||
|
||||
As the rapid development of GreptimeDB, the metrics may be changed, and please feel free to submit your feedback and/or contribution to this dashboard 🤗
|
||||
|
||||
To maintain the dashboards, we use the [`dac`](https://github.com/zyy17/dac) tool to generate the intermediate dashboards and markdown documents:
|
||||
|
||||
- `cluster/dashboard.yaml`: The intermediate dashboard for the GreptimeDB cluster.
|
||||
- `standalone/dashboard.yaml`: The intermediatedashboard for the standalone GreptimeDB instance.
|
||||
|
||||
## Data Sources
|
||||
|
||||
There are two data sources for the dashboards to fetch the metrics:
|
||||
|
||||
- **Prometheus**: Expose the metrics of GreptimeDB.
|
||||
- **Information Schema**: It is the MySQL port of the current monitored instance. The `overview` dashboard will use this datasource to show the information schema of the current instance.
|
||||
|
||||
## Instance Filters
|
||||
|
||||
To deploy the dashboards for multiple scenarios (K8s, bare metal, etc.), we prefer to use the `instance` label when filtering instances.
|
||||
|
||||
Additionally, we recommend including the `pod` label in the legend to make it easier to identify each instance, even though this field will be empty in bare metal scenarios.
|
||||
|
||||
For example, the following query is recommended:
|
||||
|
||||
```promql
|
||||
sum(process_resident_memory_bytes{instance=~"$datanode"}) by (instance, pod)
|
||||
```
|
||||
|
||||
And the legend will be like: `[{{instance}}]-[{{ pod }}]`.
|
||||
|
||||
## Deployment
|
||||
|
||||
### Helm
|
||||
|
||||
If you use the Helm [chart](https://github.com/GreptimeTeam/helm-charts) to deploy a GreptimeDB cluster, you can enable self-monitoring by setting the following values in your Helm chart:
|
||||
If you use Helm [chart](https://github.com/GreptimeTeam/helm-charts) to deploy GreptimeDB cluster, you can enable self-monitoring by setting the following values in your Helm chart:
|
||||
|
||||
- `monitoring.enabled=true`: Deploys a standalone GreptimeDB instance dedicated to monitoring the cluster;
|
||||
- `grafana.enabled=true`: Deploys Grafana and automatically imports the monitoring dashboard;
|
||||
|
||||
The standalone GreptimeDB instance will collect metrics from your cluster, and the dashboard will be available in the Grafana UI. For detailed deployment instructions, please refer to our [Kubernetes deployment guide](https://docs.greptime.com/nightly/user-guide/deployments/deploy-on-kubernetes/getting-started).

|
||||
|
||||
### Self-host Prometheus and import dashboards manually
|
||||
# How to use
|
||||
|
||||
1. **Configure Prometheus to scrape the cluster**
|
||||
## `greptimedb.json`
|
||||
|
||||
The following is an example configuration(**Please modify it according to your actual situation**):
|
||||
Open Grafana Dashboard page, choose `New` -> `Import`. And upload `greptimedb.json` file.
|
||||
|
||||
```yml
|
||||
# example config
|
||||
# only to indicate how to assign labels to each target
|
||||
# modify yours accordingly
|
||||
scrape_configs:
|
||||
- job_name: metasrv
|
||||
static_configs:
|
||||
- targets: ['<metasrv-ip>:<port>']
|
||||
## `greptimedb-cluster.json`
|
||||
|
||||
- job_name: datanode
|
||||
static_configs:
|
||||
- targets: ['<datanode0-ip>:<port>', '<datanode1-ip>:<port>', '<datanode2-ip>:<port>']
|
||||
This cluster dashboard provides a comprehensive view of incoming requests, response statuses, and internal activities such as flush and compaction, with a layered structure from frontend to datanode. Designed with a focus on alert functionality, its primary aim is to highlight any anomalies in metrics, allowing users to quickly pinpoint the cause of errors.
|
||||
|
||||
- job_name: frontend
|
||||
static_configs:
|
||||
- targets: ['<frontend-ip>:<port>']
|
||||
```
|
||||
We use Prometheus to scrape off metrics from nodes in GreptimeDB cluster, Grafana to visualize the diagram. Any compatible stack should work too.
|
||||
|
||||
2. **Configure the data sources in Grafana**
|
||||
__Note__: This dashboard is still in an early stage of development. Any issue or advice on improvement is welcomed.
|
||||
|
||||
You need to add two data sources in Grafana:
|
||||
### Configuration
|
||||
|
||||
- Prometheus: It is the Prometheus instance that scrapes the GreptimeDB metrics.
|
||||
- Information Schema: It is the MySQL port of the current monitored instance. The dashboard will use this datasource to show the information schema of the current instance.
|
||||
Please ensure the following configuration before importing the dashboard into Grafana.
|
||||
|
||||
3. **Import the dashboards based on your deployment scenario**
|
||||
__1. Prometheus scrape config__
|
||||
|
||||
- **Cluster**: Import the `cluster/dashboard.json` dashboard.
|
||||
- **Standalone**: Import the `standalone/dashboard.json` dashboard.
|
||||
Configure Prometheus to scrape the cluster.
|
||||
|
||||
```yml
|
||||
# example config
|
||||
# only to indicate how to assign labels to each target
|
||||
# modify yours accordingly
|
||||
scrape_configs:
|
||||
- job_name: metasrv
|
||||
static_configs:
|
||||
- targets: ['<metasrv-ip>:<port>']
|
||||
|
||||
- job_name: datanode
|
||||
static_configs:
|
||||
- targets: ['<datanode0-ip>:<port>', '<datanode1-ip>:<port>', '<datanode2-ip>:<port>']
|
||||
|
||||
- job_name: frontend
|
||||
static_configs:
|
||||
- targets: ['<frontend-ip>:<port>']
|
||||
```
|
||||
|
||||
__2. Grafana config__
|
||||
|
||||
Create a Prometheus data source in Grafana before using this dashboard. We use `datasource` as a variable in Grafana dashboard so that multiple environments are supported.
|
||||
|
||||
### Usage
|
||||
|
||||
Use `datasource` or `instance` on the upper-left corner to filter data from certain node.
