Error - No data was received from host!

[RIDS_I2MP]

Hi Team,

We are monitoring a windows 2003 server using the NSCLient++ , The nagios agent was working fine till recently, however off late we have been receiving warning alerts for disk drives on this server with a status message 'No data was received from host!'. we have checked with our network team and they have confirmed that there are no networks issues with this server, however, we continue to receive these false alerts. These alerts are normally valid only for a single check, i.e the status comes back to the OK state from warning in the next check. Please help

Are you having issues with disk drive checks only or all checks? Can you show us the actual command that you are running from the command line, along with the output of it? Hide sensitive info. Does the issue go away if you increase the timeout?

The issue happens with other services as well but they are configured to be checked multiple times before an email alert is sent while the disk alerts are notified immediately.

The command being used is

Code: Select all

[nagios@eu1papu003 libexec]$ ./check_nt -H IP-address -u -t 60 -s password -p 12489 -v USEDDISKSPACE -l D -w 90 -c 93
D:\ - total: 19.99 Gb - used: 0.83 Gb (4%) - free 19.16 Gb (96%) | 'D:\ Used Space'=0.83Gb;17.99;18.59;0.00;19.99

I haven't checked increasing the timeout at the moment

Do you have logging enabled in nsclient?

If not enable it:

Code: Select all

[/settings/log]
file name = nsclient.log
level = debug

If so check the nsclient logs
