Hello,

I want to write my own plugin in shell. 

It should be easy plugin reporting actual disk usage (purpose is ability to monitor multiple threshold for one partition ).

I need tu start my script with parameter. Similar way as nagios plugin, so I cant use this step from plugin guide.

=================

Create a folder under the Plugins directory in the agent installation path and place the plugin script file and other dependency files here. The name of the folder and the plugin script file should be the same.

=================

So I used way same as for nagios plugin.

=================

Include the path of the Nagios script file and its arguments and save the 'nagios_plugins.json' file.

=================

Now I have this in /monagent/logs/details/plugins.txt
=================

=================

Can someone explain me, what is going on? I am not sure what was not found.. 

Here is my script:

=================

#!/usr/bin/env bash

# Easy script reporting partition usage in percetange.

PLUGIN_VERSION="1" ###Mandatory - If any changes in the plugin metrics, increment the plugin version here.
HEARTBEAT="true" ###Mandatory - Setting this to true will alert you when there is a communication problem while posting plugin data to server
METRIC_UNITS={Partition-'%'} ###OPTIONAL - These units will be displayed in the Dashboard

get_data () {
for a in "$@"; do
con=$(df $a)
percent=$(echo ${con}| awk '{print $12}')
part=$(echo ${con}|awk '{print $8}')
printf "Partition: %s=%s\n" "${part}" "${percent} "
done
}

mandatory_attributes="plugin_version:$PLUGIN_VERSION|heartbeat_required:$HEARTBEAT"

plugin_data=$(get_data "$@")
output="${mandatory_attributes} | ${plugin_data} |units: $METRIC_UNITS "
echo ${output}

=================
 
Thanks in advance.

Best Regards,
Marek
