I am brand new to Percona Monitoring and Management. I have installed it and it seems to (finally!) work fine on 2 machines:
- a VPN for the PMM server (in a docker container)
- another VPN where I host a MySQL docker, and another docker for the PMM client
When I show the “OS / Node Summary” panel and select the MySQL node in the “Node name” dropdown, I get the following, with an “exit status 1” error in the “System Summary” box. (see screenshot below). The other information for uptime, vCPUs, load average etc are correct.
When I select the PMM server node instead, then the text information is displayed properly in that “System Summary” box.
Do you know what I did wrong and how to fix this?
