Nagios NSCA error

[ayush1440]

Hello Friends,

I am very newbie for Nagios and specially for NSCA. I configured nagios core & plugin successfully and works very well on Ubuntu Server.

Now requirement is to configure nsca for tomcat log4j monitor. I configure nsca as wiki & how to docs and works but I have some confusion on this.

Here is my configuration. : -

Templates.cfg - end Section

Code: Select all

define service{
        use                             generic-service
        name                            passive_service
        active_checks_enabled           0
        passive_checks_enabled          1
        flap_detection_enabled          0
        register                        0
        is_volatile                     0
        check_period                    24x7
        max_check_attempts              3
        normal_check_interval           3
        retry_check_interval            1
        check_freshness                 0
        freshness_threshold             180
        contact_groups                  admins
        notification_interval           60
        notification_period             24x7
        notification_options            w,u,c,r
        stalking_options                w,c,u
        }

Inside localhost.cfg

Code: Select all

define service{
        use                             passive_service
        service_description             TestMessage
        host_name                       Pompei
        check_command                   check_dummy!0
        }

Nagios Error Log

I tried several things by Google but can't help anything.

Also on my web ui service last checked is shown but Next schedule check shown as a N/A.

kindly please help me on this.

Help would be really appreciated. Further information will be given if required.

Sorry for bad english..

Thanks & Regards,

I think you got bit by the empty whitespace. You're sending:

Code: Select all

localhost ;TestMessage ;3;This isdsfhksdfjskf a Test Error 

Try:

Code: Select all

localhost;TestMessage;3;This isdsfhksdfjskf a Test Error 

You don't want spaces in between the semi-colons.

Thanks a lot for replying.

I am using test.txt for testing purpose. Here is a test.txt detail

Code: Select all

localhost   TestMessage   3    This isdsfhksdfjskf a Test Error

I am using following command :

/usr/local/nagios/bin/send_nsca -H localhost -p 5667 -c /usr/local/nagios/etc/send_nsca.cfg < /root/test.txt

When I executing your code in text I receive .0 data packet(s) sent to host successfully.

Can you please give me some other string for check.

Also I show in my webui, configured Passive check service don't update automatically for this test.

Try this in the text file:

Code: Select all

localhost;TestMessage;3;'This isdsfhksdfjskf a Test Error'

And this command:

Code: Select all

/usr/local/nagios/bin/send_nsca -H localhost -d ';' -p 5667 -c /usr/local/nagios/etc/send_nsca.cfg < /root/test.txt

(added a semi-colon as a delimiter). I would suggest always single quoting your plugin output as well.
