Can you please help how to remove pmm-agent service and stop all services running on this node related to pmm and do not want to monitor this node only.

2

can any one help me to remove the pmm client completely from node

3

Hello! Thank you for your report, we created ticket for this issue - [PMM-11280] Can't remove pmm-client from node - Percona JIRA

4

I’m sorry, my wrong. By this command pmm-client should be completely uninstalled. Can you show result of “systemctl status pmm-agent”

5

home/# systemctl status pmm-agent
â—Ź pmm-agent.service
Loaded: masked (/dev/null; bad)
Active: inactive (dead)

6

Do you have docker with running pmm-client at this PC?

7

thanks @Anton_Bystrov i have checked and it seems it running with the docker.

I have tested using stoping docker on node and it seems pmm is runing with docker client
