Since I’ve switched my homelab from esxi to proxmox, I have a strange issue. lnms will periodically claim the proxmox host is down for hours, while happily graphing all the vm’s that run on this supposedly offline machine.
lnms event log claims “Device status changed to Down from snmp check.”, then few hours later it will say up from snmp check and so on.
Anytime lnms sees it as offline, if I log on the lnms machine, I can succesfully ping the proxmox host, and fping returns “… is alive”. Both snmpbulkwalk and telnet 6556 correctly fetch all values. The graylog plugin continues to feed the syslog messages from the proxmox host to lnms, so they keep popping up, but the machine name is red and there are huge gaps in the graphs. All the machines finish polling in time, the proxmox host takes on average 10-15sec to poll.
Any idea what could be going on? I already tried the windows solution of restarting everything from the router to each switch and machine to no avail.
I’ve activated 1 min ping but despite both ping and fping can reach the machine lnms won’t pick it up. The only thing I can think of that is different to the esxi host is that the proxmox host only has ipv4 address which is how I purposefully set it up as I do not understand ipv6 addresses at all, and seeing as my isp doesn’t provide ipv6 connection I have no use for them.
