Hello, periodically I have “gaps” in my graphs which appears to be when Observium was unable to reach a particular host. This problem occurs on multiple hosts at the same time on different network segments and I have been unable to find any commonality except for the Observium server itself. I noticed that the gaps in the graph also exist at the same times for Observium’s checks of localhost. Checking localhost of course demonstrates this is not a lack of network connectivity outside of the server.

At these times I also found these entries but I’m not sure if they are related since they are merely syslog messages but thought I’d mention it:

Jan  1 21:39:24 voldemort rsyslogd-2177: imuxsock begins to drop messages from pid 27161 due to rate-limiting

Jan  1 21:45:50 voldemort rsyslogd-2177: imuxsock lost 22 messages from pid 27161 due to rate-limiting

root@observium(~)

:ps auxw | grep 27161

root     27161  0.0  0.0 200848  6520 ?        S     2019  15:32 /usr/sbin/snmpd -LS0-6d -Lf /dev/null -p /var/run/snmpd.pid

What would cause this and how can I solve this matter?
