I’m having an issue with check_mk and/or graphite. For network devices, check_mk is set to run snmp checks every minute. Yet for some reason, an update is sent to graphite/grafana every 30 seconds. So what happens, is every other data point
in grafana is 0. So the graphs bounce between the actual value and 0 every 30 seconds, causing a series of triangles. I’m not sure if the problem is check_mk or grafana. Any ideas?
The RRD rules are configured for a step of 60 as well.
This started happening after upgrading check_mk from 1.2 to 1.5.0. Previously, the empty data points would be sent to graphite as null. Since the upgrade, they are sent as 0. How can I change this back?

Ok, so I got this working. Or at least have a work around. The normal check interval for host checks and snmp checks were both set to 1 minute. However, the normal check interval for service checks was set to
30 seconds. So every 30 seconds the Check_MK service would update, but the SNMP checks would not. This produced the empty data points in grafana. I set a rule to have the normal service check interval for the Check_MK service for these devices to 1 minute
to match.
We’d prefer to have all these at 30 seconds, but it appears as if 1 minute is the smallest possible interval for SNMP checks. Is that right?

Hi Mike,
If you have no rule for SNMP check interval, all SNMP checks should be
checked in the same interval as your normal check interval is.
That means if you set your normal interval to 30 seconds and have no
rule for SNMP checks these checks should also be executed every 30
seconds.
Best regards
Andreas
