Hi Guys,
On a limited number of CentOS & Ubuntu machines we are monitoring with Observium we are seeing dozens of SNMP queries from Observium in a very short window (10-20 seconds).
Snip of the logs from /var/logs/messages

We are trying to understand why Observium would be sending so many queries back to back as well as why we are seeing this on some machines, but not others.
Thanks!
