Building a Monitoring Extension Using Scripts

[Predrag.Spasic]

Hi,

Trying to create POC for building custom monitoring extension from (custom written) scripts.

• Created <machine_agent_home>/monitors/<custom_extension_directory>, in my case that is <machine_agent_home>/monitors/CustomMonitor”.
• In this directory CustomMonitor created two files. First file is shell script that prints stdout in the format of "name=Custom Metrics|Hardware Resources|$ZONE|$server_name conntrack utilization percent,value="$Ctrack_utilization. This works just fine, tested it by running from the server directly, from command prompt.
• created file “monitor.xml” with the following content …

  <monitor>

                 <name>Hardware Resources</name>

                 <type>managed</type>

                 <description>Monitor open file count </description>

                 <monitor-configuration>

                 </monitor-configuration>

                 <monitor-run-task>

                                <execution-style>continuous</execution-style>

                                <name>Run</name>

                                <type>executable</type>

                                <task-arguments>

                                </task-arguments>

                                <executable-task>

                                               <type>file</type>

                                               <file><shell_script_file_name></file>

                                </executable-task>

                 </monitor-run-task>

  </monitor>
• restarted machine agent

My data is not visible if i go to Servers > Metric Browser.

Tried modifying monitor.xml to use periodic (since i read somewhere that for "continuous" script needs to run in infinite loop like this ...

<execution-style>periodic</execution-style>
<execution-frequency-in-seconds>60</execution-frequency-in-seconds>
<execution-timeout-in-secs>30</execution-timeout-in-secs>

but my data is still not visible in Metric Browser.

Tried with different format of stdout like this ...

name=Hardware Resources|$ZONE|$server_name conntrack utilization percent,value="$Ctrack_utilization

but that did not help neither.

Just to mentioned that in Metric Browser I see relevant server with default metrics, this is what i see under this server (did not include it in the image in order not to reveille the actual server name)

I was hoping to have another expandable folder with the caption of the value of variable $ZONE.

Has anyone successfully managed to get this running?
