Hi Fan

Can you run this with verbose option:

pmm-admin --verbose ...

Also, can you attach the logs:

/var/log/pmm-mysql*.log
#3

this time i purge linux:metrics (don’t support markdown, so the format is terrible)
[root@node002142 fanboshi]# pmm-admin add linux:metrics
OK, now monitoring this system.
[root@node002142 fanboshi]# pmm-admin uninstall
OK, 1 services were removed.
[root@node002142 fanboshi]# pmm-admin purge linux:metrics
panic: interface conversion: interface {} is nil, not map[string]interface {}

Has this bug been fixed in 1.14? @Michael Coburn

I see the same issue. I’m running the OVA and MySQL community server on the the client. All the pmm services are running properly on both boxes, as far as I can tell. I removed the linux:metric service, and then purged. I don’t see a log file in /var/log for the linux:metrics service.

sudo pmm-admin --verbose purge linux:metrics

Some data has been elided for security

Hi Fan , andycutright , and Tim Schmolzi

Thanks for reporting this issue - turns out we’re trying to execute Prometheus 1.x (delete series) API calls against Prometheus 2.x backend. We’re tracking this issue in our JIRA under https://jira.percona.com/browse/PMM-2845 , and we are targeting our October release (tentatively Oct 10) for a fix.
