OS node overview: Metrics disappear from the graph when instances are added to pmm using

Percona Monitoring and Management (PMM) PMM 2.x
, ,
1

Description:

When I added the first DB instance(Aurora MySQL) to pmm, OS metrics were visible in the OS / Node Overview dashboard.
But when I added the second DB instance, the OS metrics for first DB instance disappears and the second DB instances never show up.
Metrics only visible for pmm-server.

Note: Logstreams in cloudwatch has the logs as expected.

Steps to Reproduce:

  1. Add 1 DB instance (Aurora MySQL) to pmm through IAM user (and policy as per percona documentation). Check OS / Node overview dashboard (It shows the metrics for the DB instance that was added)
  2. Add 2nd DB instance (same procedure as first). Check OS / Node Overview dashboard. For me, metrics disappear for the first instance and metrics for second instance did not appear)
  3. Metrics only visible for pmm-server.

Version:

Percona: pmm 2.43.1
Database: 8.0.mysql_aurora.3.05.2

Expected Result:

Metrics for all the database is expected to be seen in OS / Node overview

Actual Result:

When 1 db instance is added the metrics is visible. When 2nd instance is added, the metrics disappears for both.
Metrics only visible for pmm-server.
