Nagios Support Forum

Hello Team,

one windows server we are getting alerts frequently and the alert is showing the error " WARNING:No data was received from host!"
That server is a backup server but backup scheduling time and alert time is not matching . sometimes alerts time is matched with backup time .

Every alternative days we are getting alerts frequently .
For example today I received alerts for H drive and after sometime it's started working and tomorrow I will receive alerts for I drive.

Could you please help me to resolve it ?

Can you show us how the "failing" services are configured? What is the version of the NSClient++ agent that you are using on the Windows machines? Have you tried restarting the NSClient++ service to see if this is going to resolve the issue? Can you check the nsclient.log for any warnings or errors pertaining to these checks?

Hello,

PFB Screen shot for the service configuration and state history report for failing services.

As per nagios recommendations for all the failing services we have set the Check interval - 5, retry interval -1, max check attempts -5.

Yes we have already tried restarting nsclient++ service but issue not resolved

nsclient version:0.3.9.328

Maybe your Windows server gets really busy, especially during backups, and your check is timing out. Try the following:

1. Increase the "default" value of 30 for the timeout under the [/settings/default] section in the nsclient.ini file on the Windows machine: Save, exit, and restart the nsclient++ service.

2. Modify your "Drive H: Disk Usage" check by adding a timeout to it.

Example:

/usr/local/nagios/libexec/check_nt -H x.x.x.x -s "password" -p 12489 -t 59 -v USEDDISKSPACE -l H -w 80 -c 90

Note: I used a timeout of 59 seconds as the default service timeout is set at 60 in the nagios.cfg file anyway. Let us know if increasing the timeout helps.

Note: If 60 seconds is still not enough, you may need to increase it even more, but you would need to change the service_check_timeout value in the nagios.cfg file too.

Hello,

Now that server is working fine since few days. so we will keep it in under observation . if any issue will come I will try to increase the timeout and check it out.

Sounds good! Let us know if you want us to keep the topic open for the time being. Thank you!

yes...keep the topic open for the time being . let you know once it's resolved completely
