Can I have old PCP metrics getting removed from graphs in Grafana automatically?
Issue
- We are running the normal chain with
pmloggerlogging metrics into PCP archive files, thenpmproxyfetching the data intoredis, andgrafanavisualizing the metrics. Our archive files span a retention period of 14 days. How can we makegrafanaonly display the past 7 days of metrics for each host? - Why is Grafana (with PCP/pmproxy/redis behind it) just showing a small part of the days which are covered by the pmlogger archive logs?
Environment
- Red Hat Enterprise Linux (RHEL) 8 and later
- Performance Co-Pilot (PCP)
- redis
- grafana
