Monitoring a Windows host over the WAN link best pratice

[steven.giang]

Hi Guys,

I'm aware there is a latency issue for using this method to monitor a remote host over the WAN link.

I have setup the host monitor over the WAN however I am constantly getting services are flapping. I have also enable passive check however I'm not familiar with all other setting and hope someone here could pin point what "Check Settings" should I need for this requirement. Please see attached of the current setting of the services.

Thanks you in advance,

Steve

What errors are you getting?

A screenshot of the "Common Settings" tab would be helpful.

Hi Box293,

Please see attached, as mention previously the services is flapping stage. is there way to tune for checking services multiple time before it confirm the status (by-pass the flapping)

This sounds like a timeout issue.

Go into CCM > Commands
Edit the command check_xi_service_nsclient
Change it to:

Code: Select all

$USER1$/check_nt -H $HOSTADDRESS$ -s "$ARG1$" -t 30 -p 12489 -v $ARG2$ $ARG3$ $ARG4$

Save and apply config.

You can see I added -t 30 to increase the timeout to 30 seconds.

Does this fix your problem?

If it doesn't, send us the output from one of the services when it is in a critical state.

Yes, I can set the timeout to longer, dos this really counter the latency over the WAN?

[Box293]

It all depends on how saturated your link is, or how long it takes for the Windows host to respond to the requests.

There's only one way to find out, implement the timeout.

Thanks you I will set the timeout for 40 and see how it goes,

Thanks guys, the longer timeout does help through the issue. Please close the ticket and I'm very appreciated for your help. Great product for customisation when needed
