I’m using the PMM OVA 1.2.0 on my computer for testing. Collection worked fine over the weekend. Today my computer crashed, so did the VM. After restart, pmm-status check-network displays:
- Connection: Client ← Server
SERVICE TYPE NAME REMOTE ENDPOINT STATUS HTTPS/TLS PASSWORD
linux:metrics winelounge-db-linux 1.2.3.4–> 4.3.2.1:42000 DOWN YES YES
mysql:metrics winelounge-db-mysql 1.2.3.4–> 4.3.2.1:42002 DOWN YES YES
Both server and client are in separate networks, behind NAT. I verified that NAT rules are still intact. /var/log/pmm-*.log contains no recent error. When visiting /prometheus/targets, all targets are up. What could be wrong, how can I investigate?
