Service in Warning state

Hi,

One of the services is in Warning state. Remote server is Windows server.

We are using Nagios core.

Following is the check command.

check_http -H 10.211.68.12 -u VoiceConsole/login.action?error=true -p 9090

[root@nagios server]#./check_http -H 10.211.68.12 -u VoiceConsole/login.action?error=true -p 9090
HTTP WARNING: HTTP/1.1 400 - 1339 bytes in 0.002 second response time |time=0.002331s;;;0.000000 size=1339B;;;0

I did some troubleshooting.

[root@nagios server]# ./check_nrpe -H 10.211.68.12
Could not construct return paket in NRPE handler check clientside (nsclient.log) logs...

[root@nagios server]# ./check_nrpe -H 10.211.68.12 -2
I (0.3.8.76 2010-05-27) seem to be doing fine...

[root@nagios server]# ./check_http -H 10.211.68.12 -u VoiceConsole/login.action?error=true -p 9090 -v

What could be the problem.

This looks like the plugin is returning a WARNING because the page is returning a 400 server response which would be expected

you should see the same results with a curl of the URL

Code: Select all

curl "http://10.211.68.12:9090VoiceConsole/login.action?error=true" -vvv

Looking at my response I think I see the error, you are missing the leading / in the URI

try

Code: Select all

./check_http -H 10.211.68.12 -u /VoiceConsole/login.action?error=true -p 9090

I tried this and it is working fine.

./check_http -H 10.211.68.12 -u /VoiceConsole/login.action?error=true -p 9090

Thank you so much for your help.
