Hi,
if you’re talking about ping/icmp jitter, than yes, checkmk does include it, but indirectly.
Jitter as far as I understand gives the spread of ping return times around the average. So i.e. if you sent 3 pings and the slowest is at 75ms, the fastest at 25ms and the third at 50ms, your jitter will be (75-25) => 50ms
Checkmk instead reports the min and maximum in the ping, so you have a more detailed info, but can calculate the jitter if you need it in one number:
see the perfdata of a ping check attached:
