JBoss check problem

[hbouma]

Ok, now we are getting somewhere.

For some reason, Wildfly is refusing the connection. I will have to research on my side what is going on.

Thanks

Sorry, I had a mistake in the ncpa.cfg entry, here's what worked for mine:

Code: Select all

/usr/local/nagios/libexec/check_ncpa.py -H 192.168.X.X -t 'XXXXX' -P 5693 -M plugins/check_jvm.jar -q "args=-s service:jmx:remote+http://127.0.0.1:9990,args=-u 'XXXXXX',args=-p 'XXXXXX',args=-t jboss,args=-C 'MemorySimpleHeap,MemoryMetaspace,ProcessCPUUsage,SystemCPUUsage,Uptime',args=-w '17179869184,34359738368,50,70,1500000:',args=-c '32212254720,68719476736,70,90,300000:'"

The /usr/local/ncpa/etc/ncpa.cfg entry:

Code: Select all

.jar = java -Djava.class.path=/opt/wildfly/bin/client/jboss-cli-client.jar:$plugin_name GenericASCheck $plugin_args

This is what works directly from the wildfly server:

Code: Select all

su - nagios
cd /usr/local/ncpa/plugins
java -Djava.class.path=/opt/wildfly-19.0.0.Final/bin/client/jboss-cli-client.jar:check_jvm.jar GenericASCheck -s 'service:jmx:remote+http://127.0.0.1:9990' -t jboss -C 'MemorySimpleHeap,MemoryMetaspace,ProcessCPUUsage,SystemCPUUsage,Uptime' -w '17179869184,34359738368,50,70,1500000:' -c '32212254720,68719476736,70,90,300000:'

Does that work for you?

Once I changed the nagios user to have permissions to read from our DOMAIN/tmp/auth folder, this method worked.

Thank you!

Also, is there a way to monitor the DB connections with this jar? For instance, to alert if the datasource is out of connections?

I don't think you can do it with this plugin, here is a list of what the plugin supports, see the check-types section:

Code: Select all

[root@jboss_wildfly plugins]#  java -Djava.class.path=/opt/wildfly/bin/client/jboss-cli-client.jar:check_jvm.jar GenericASCheck                                                                                                               -h

                          one of this and warning must be entered.
 -C,--check-types <arg>   A list of the checks that should be run. Valid
                          checks: Uptime, MemorySimpleNonHeap,

                          MemoryOld, MemoryCodeCache,
                          MemoryCompressedClass, MemoryMetaspace,

                          SystemCPUUsage. Tomcat servers also have the
                          checks RequestsPerMinute, BytesPerMinute,
                          BytesPerRequest, ErrorsPerMinute, and
                          ProcessingTimePerRequest. Note:
                          RequestsPerMinute, BytesPerMinute,
                          BytesPerRequest, ErrorsPerMinute, and
                          ProcessingTimePerRequest also require the name
                          of the relevant request processor. For example,
                          "RequestsPerMinute:http-nio-0.0.0.0-8080". For
                          rate-based checks, a negative value may be
                          returned after a counter is reset.

Thank you. That is all I needed.
