[Check_mk (english)] How to increase time or threshold before host is reported as down

Archive checkmk-en
1

Hi,

I’d like to decrease the occurrence of alerts about hosts being down in my environment. Where would I configure this, and what is the best method for doing so?

Thanks,

Marc

Rules…

WATO - Configuration -> Host and Service Parameters ->

Monitoring Configuration → Periodic notifications during host
problems

I think it defaults to every 60 minutes. I created a rule in the

main folder to set it to 1440 (once a day).

Another option (not sure if you mean the mails):

WATO → Notifications → notification rule you are using → Restrict to nth to mth notification

I think this is the direction I want to go in. Some of my hosts might be unresponsive for 20 seconds (which does seem like a long time, and is something I need to look into), but they come back within that span of time.

Thanks for your help,

Marc

Perhaps there’s an even better solution in that case.

Check this link: http://lists.mathias-kettner.de/pipermail/checkmk-en/2013-November/010805.html

It’s about ‘Maximum number of check attempts for service’.

This way it won’t even be a crit in Check_MK web gui before it fails x times (for me, x=3).

I thought you meant for long term host issues. For short term
glitches like that I use a different rule
to suppress notifications:

WATO - Configuration -> Host and Service Parameters ->

Monitoring Configuration → Delay host notifications

You can create a rule and set it to...say 15 minutes. Then the host

would have to be down for 15 minutes before
the first notification is sent. I use that one and the ‘Delay
service notifications’ rules to keep from sending
notifications for host and service glitches. They still show up on
the screen, but it gives the guys watching the screen
time to verify or fix the problem before email is sent. I’ve got
different rules in different folders. Some users want
a notification after 5 minutes, others want to wait 30 minutes
before being notified…

This worked! I set the delay for 5 minutes, and downed a test host for 3 minutes. No alerts were sent. Perfect!

Thanks,

Marc
