How to test the Plugin and what are the main options for?​
Once the plugin installed, log into your Centreon Poller CLI using the centreon-engine user account and test the Plugin
by running the following command (Some of the parameters such as proxyurl have to be adjusted):
/usr/lib/centreon/plugins/centreon_slack_restapi.pl \
--plugin='apps::slack::restapi::plugin' \
--mode=services \
--proxyurl='http://myproxy.mycompany.org:8080' \
--filter-name='Connections|Messaging' \
--warning-status='%\{status\} eq "active" and %\{type\} eq "incident"' \
--critical-status='%\{status\} eq "active" and %\{type\} eq "outage"' \
--verbose
Expected command output is shown below:
OK: All slack services are ok | 'slack.services.count'=2;;;0;
Service 'Connections' status is ok
Service 'Messaging' status is ok
In this example, the Plugin gets the status Slack services (--plugin='apps::slack::restapi::plugin' --mode=services)
by requesting the official Slack API. Only the status of the Connections and Messaging services will be displayed (--filter-name='Connections|Messaging').
This command would trigger a WARNING alert if one of the service is reported as degraded (--warning-status='%{status} eq "active" and %{type} eq "incident"')
and a CRITICAL alert for a total outage on an service (--critical-status='%{status} eq "active" and %{type} eq "outage"').
All the filters that can be used as well as all the available thresholds parameters can be displayed by adding the --help
parameter to the command:
/usr/lib/centreon/plugins/centreon_slack_restapi.pl \
--plugin='apps::slack::restapi::plugin' \
--mode=services \
--help
