Hi,

I upgrade PMM server from v2.39 to v2.44, running on docker.
followed this link - Docker - Percona Monitoring and Management

After the upgrade QAN is empty.
log show:
stdlog: qan-api2 v2.44.0.
time=“2025-01-15T10:24:35.723+00:00” level=info msg=“Log level: info.”
time=“2025-01-15T10:24:35.723+00:00” level=info msg=“DSN: clickhouse://127.0.0.1:9000?database=pmm&block_size=10000&pool_size=2” component=main
stdlog: dsn: clickhouse://127.0.0.1:9000?database=pmm&block_size=10000&pool_size=2
stdlog: Migrations: Dirty database version 17. Fix and force version.

Steps to Reproduce:

upgrade PMM server from v2.39 to v2.44, running on docker.
using docket upgrade,

What should I fix in order to resolve it?

Thanks,
Eldad

Hi @eldad ,

Did you also check the upgrade logs? Does the clickhouse error log show any other messages regarding failures in the upgrade process?
