Work on https://github.com/neondatabase/cloud/issues/23721 and
https://github.com/neondatabase/cloud/issues/23714
Depends on https://github.com/neondatabase/neon/pull/11111
- Add `/configure_telemetry` API endpoint
- Support second rsyslog configuration for Postgres logs export
- Enable logs export when compute feature is enabled and configure
Postgres to send logs to syslog
I have used `/configure_telemetry` name because in the future I see it
also being used for configuring a `pg_tracing` extension to export
traces. Let me know if you'd rather have these APIs separate. In this
case we can rename it to `/configure_rsyslog`.
- add pgaudt_gc thread to compute_ctl
to cleanup old pgaudit logs if they exist.
pgaudit can rotate files, but it doesn't delete the old files
- Add AUDIT_LOG_DIR_SIZE metric to compute_ctl
to track the size of the audit log directory in bytes.
- Fix permissions for rsyslog state files directory
Setup pgaudit and pgauditlogtofile extensions
in compute_ctl when the ComputeAuditLogLevel is
set to 'hipaa'.
See cloud PR https://github.com/neondatabase/cloud/pull/24568
Add rsyslog setup for compute_ctl.
Spin up a rsyslog server in the compute VM,
and configure it to send logs to the endpoint
specified in AUDIT_LOGGING_ENDPOINT env.
