On a fairly new install of 1.65.1 using docker compose method on Ubuntu 18.04, Things were working fine for about 8 hours. I was polling about 20 HP switches and traffic data was appearing beautifully.
Then the next day, everything still appears to be working fine except no new data appears in the graphs. I can see the 8 hours worth of data appearing in historical graphs, but nothing new appears.
Polling appears to happen successfully, and I can see new SNMP event data from the switches and I can even successfully display real-time data when looking at a particular port. So I know it is able to communicate successfully with the switches.
Validate Config shows all is good.Can anyone suggest some avenues for troubleshooting this? It is weird that everything looks fine and no notable errors are appearing in syslog (are there other log locations to look at?).
