Hello,
I have some hosts in stale state for some days now. I can ping them from the checkmk site user but the check don’t get any updates. I set a rule to ensure that ping is used because I have tried this.
Is there a way to reset this stale state?
When the hosts where gets stale there was a network issue which is now resolved. The hosts have no parent configured.
Can anyone help me with this?
Thanks
Hi,
stale means the checkmk server does not get the data from the agent to determine a new state. Please check the output of the agent from the servers with stale state if the information and sections needed for the check are provided by the agent.
I know this. with services. But my problem is that the host is stale.
Oh, okay, sorry i got the information wrong.
Which check do you have defined for host available check?
The rule is called Host Check Command.
Host Check Command is set to PING. I changed it to SmartPING but with no success.
edit:
I tried to use “Diagnostic” and there can I see the working ping.
Perhaps “host checks” are disabled? Check the “Master Control” sidebar snap-in.
Are only some hosts affected while for other hosts the host check is recent?
It is only one site with this problem. all other hosts are working. I’ll check the snap-in
The master control on that specific site was off. Thanks for your help!
Stupid simple problem 
Glad it helped!
If you monitor your SITE’s server, then you should have a service “OMD SITE performance”. You can then configure this check to go WARN or CRIT when checks/notifications/… are disabled:
WATO → Host & Service Parameters → Parameters for discovered services → Performance and settings of a Check_MK site
State when the site is stopped
State when host checks are disabled
State when service checks are disabled
State when not accepting passive host checks
State when not accepting passive service checks
State when not checking host freshness
State when not checking service freshness
State when event handlers are disabled
State when flap detection is disabled
State when notifications are disabled
State when performance data is disabled
State when not checking external commands
