Aurora Postgres support by PMM. Most of metrics are N/A

[Vasil]

Hello everyone,
PMM 2.32.0
Aurora PostgreSQL, Engine version:13.8

I plugged Aurora PostgreSQL to our PMM according to this instruction: Amazon RDS - Percona Monitoring and Management but unfortunately I get N/A for most PostgreSQL dashboard graphs

The following parameters are also set for Aurora PostgreSQL:
shared_preload_libraries = ‘pglogical,pg_stat_statements’
track_activity_query_size = 2048
pg_stat_statements.track = all
track_io_timing = 1

There is also a PostgreSQL instance deployed on EC2. It connects and displays all metrics without any problems.
Is N/A in graphs a result of incomplete Aurora PostgreSQL support or is it a configuration issue? Perhaps someone has faced something like this?

Hey @Vasil,
Just to confirm that when you created the RDS PGSQL, you enabled CloudWatch metrics, and you added this instance to PGSQL by using the RDS discovery within PMM?

Hello @matthewb,
Yes, I added Aurora PoastgreSQL using auto-discovery, as well as added the necessary policies to the AWS account role to access CloudWatch.

Hi Vasil

Could you check if you have system metrics for RDS node?
You may check amount of metrics for this node in Explore

count({node_name="database-1-instance-1"})

Hi @Vadim_Yalovets

@Vadim_Yalovets almost all OS metrics are available for this instance.
