many holes in pmm grafana (pmm-admin check-network --no-emoji error sometimes)

Hello,

I use pmm (version 1.0.6) for monitoing mysql/mariadb + linux os
While I put more than 20 clients servers for monitoring, I get sometimes holes in pmm grafana and in the same time, pmm-admin check-network --no-emoji error as following in all the clients

  • Client <-- Server

SERVICE TYPE NAME REMOTE ENDPOINT STATUS


linux:metrics dl360s-62 10.198.234.139:42000 PROBLEM
mysql:metrics MAD_FUNDTP2_PRD 10.198.234.139:42002 PROBLEM

This hole (error) can last 1 minute to thirty minutes and all is ok on app server + network + firewall + all clients
And then all works, 1 hour (or dozen minutes) later, error (hole) again and so on.

I haven’t this problem when i put less clients servers for monitoring

Someone knows what’s matter with pmm ?

Thanks a lot
Regards
Pierre
