uptime thresholds

[MichielvM]

Hello all,

I was looking for a way to get alerts if a Windows host goes down 'in between checks'

There loads of SNMP related stuff out there, but my eye fell on a what's new text.

1.4.16 27th June 2012
ENHANCEMENTS
check_nt UPTIME accepts warning/critical thresholds (Ryan Kelly)

I could work with this, sadly there's 0 information to be found about this.
What syntax or arguments to parse etc.
Do I need $ARG3$ and $ARG4$? If so, what do I enter in there?

I found a link that explains how the thresholds work for check commands and here is the link to it so you can review it.

If you could give me more details on how your checks are setup currently, I might be able to help you better.

One example I have is if you want to create an alert if the up time is less than 5 minutes, you would use the following

-w 5:
this will create a warning if the up time is less than 5 minutes

If you want a critical error if the up time is less than 5 minutes, you would use
-c 5:

If you have any more questions, please post back.

Thanks.

What is was really after was getting an alert if a server has rebooted.
I.e. in the Windows eventlog a Coldstart event is generated.

I figured when an uptime check results in less than x time, the host has been down.
I'll give your link and comments a go. will check back.

I found a couple of plugins that can check for if a Windows host has been rebooted.
Try one of these out and let us know if they will work for you.

Sorry for this late reply. I got it working using above tresholds.
