Issue in configuring Nagios Appender

[Jarlath Lyons]

You need to make sure that you tell send_nsca to use the same encryption scheme that the server is using.    Since you're the client, you don't control this .... The server will have it's own file specified  .....

On my server  .....

[root at jlyonslx test_harness]# cat /etc/xinetd.d/nsca
# default: on
# description: The nsca service can deliver nagios commands to the nagios server
service nsca
{
        disable                 = no
        flags                   = REUSE
        port                    = 5667
        socket_type             = stream
        protocol                = tcp
        wait                    = no
        user                    = nagios
        group                   = nagios
        passenv                 = PATH
        server                  = /usr/local/nagios/addons/nsca/nsca
#       env                     = HOME=/usr/local/nagios
        server_args             = -c /usr/local/nagios/addons/nsca/nsca.cfg --inetd
#       bind                    = 127.0.0.1
}


The simplest thing to do is copy the nsca.cfg file to anywhere you need it when running the client .....

Thanks Again. It helped.

Now, I am stuck with following exception -

Received invalid packet type/version from client - possibly due to client using wrong password or crypto algorithm?

I am not using any password and the decryption_method is set to 0 in nsca.cfg file.

What can be the possible cause of the error then?

Thanks & Regards,
Sakshi Anand

Try shortening the name you are using, and at least remove the space between Connection and Monitoring.

Thanks Lyons.

Now, after adding the appender-ref, I am getting following exception -


log4j:ERROR Parsing error on line 18 and column 94

log4j:ERROR Attribute value "NAGIOS-Connection Monitoring" of type ID must be a name.

log4j:ERROR Parsing error on line 47 and column 54

log4j:ERROR Attribute value "NAGIOS-Connection Monitoring" of type IDREF must be a name.



Does anyone have any idea about reason of this error.



Thanks & Regards,

It appears the appender is correctly defined, but just not linked to the root logger ....

Try this ...


<root>

<level value="DEBUG" />

<appender-ref ref="CA" />

<appender-ref ref="FA" />

<appender-ref ref="NAGIOS-Connection Monitoring" />

</root>

All,

I am trying to configure nagios appender for one of my applications which is using log4j to log data. Also, my NSCA configuration is running fine.

However, I am not able to send checks from the application using nagios appender.

Following is what my log4j.xml looks like (it is successfully writing to console and to log file too) -


<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

<log4j:configuration xmlns:log4j='http://jakarta.apache.org/log4j/'>

<appender name="CA" class="org.apache.log4j.ConsoleAppender">

<layout class="org.apache.log4j.PatternLayout">

<param name="ConversionPattern" value="%-4r [%t] %-5p %c %x - %m%n" />

</layout>

</appender>

<appender name="FA" class="org.apache.log4j.FileAppender">

<param name="File" value="C:\\eclipse\\workspace2\\NSCA-PassiveChecks\\nagiosAppenderDemo\\Log4jDemo.log"/>

<layout class="org.apache.log4j.PatternLayout">

<param name="ConversionPattern" value="%-4r [%t] %-5p %c %x - %m%n" />

</layout>

</appender>

<appender class="org.apache.log4j.nagios.NagiosAppender" name="NAGIOS-Connection Monitoring">

<param name="Host" value="rpc1934.daytonoh.ncr.com"/>

<param name="Port" value="5667"/>

<param name="ServiceNameDefault" value="uContainer"/>

<param name="useMDCServiceName" value="false"/>

<param name="useMDCHostName" value="false"/>

<param name="useShortHostName" value="false"/>

<param name="Log4j_Level_ERROR" value="NAGIOS_CRITICAL"/>

<param name="Log4j_Level_FATAL" value="NAGIOS_CRITICAL"/>

<param name="ExcludeFilterEnabled" value="true"/>

<param name="PatternFilterFile" value="NagiosIncludeExcludeFilters.properties"/>

<param name="SendStartupMessageOK" value="Application Errors Cleared"/>

<layout class="org.apache.log4j.PatternLayout">

<param name="ConversionPattern" value="server: %X{Connection Monitoring}: %m%n"/>

</layout>

</appender>

<root>

<level value="DEBUG" />

<appender-ref ref="CA" />

<appender-ref ref="FA" />

</root>

</log4j:configuration>



Please help me in finding the issue and a way to debug it.



Thanks & Regards,

Sakshi Anand
