PagerDuty Events

PagerDuty + Centreon Integration Benefits

  • Notify on-call system or application administrators when an alert is detected by Centreon.
  • Incidents will automatically resolve in PagerDuty when Centreon detects that the check point is back to normal.
  • Create high and low urgency incidents based on the state of the alert.
  • Send metrics when available to give more insight about the alert.

How it Works

  • Every time a service or a host's state is checked, the event passes through Centreon Broker, which loads the Stream Connector to send state changes.
  • State changes can occur in case of an anomaly detection or metrics falling out of range.
  • Once the check point is back to normal, a resolve event will be sent to the PagerDuty service to resolve the alert.
  • You can choose from where the stream connector is sending data. Pick the implementation which best meets your needs:

Before starting

  • You can send events from a central server, a remote server or a poller.
  • By default, this stream connector sends host_status and service_status events. The event format is shown there.
  • Aformentioned events are fired each time a host or a service is checked. Various parameters let you filter out events.

Installation

Login as root on the Centreon central server using your favorite SSH client.

Run the command according on your system:

dnf install centreon-stream-connector-pagerduty

Configuration

To configure your stream connector, you must head over the Configuration --> Poller --> Broker configuration menu. Select the central-broker-master configuration (or the appropriate broker configuration if it is a poller or a remote server that will send events) and click the Output tab when the broker form is displayed.

Add a new generic - stream connector output and set the following fields as follow:

Filter categoryNeb

Add PagerDuty mandatory parameters

Each stream connector has a set of mandatory parameters. To add them you must click on the +Add a new entry button located below the filter category input.

Add PagerDuty optional parameters

Some stream connectors have a set of optional parameters dedicated to the Software that they are associated with. To add them you must click on the +Add a new entry button located below the filter category input.

Standard parameters

All stream connectors can use a set of optional parameters that are made available through Centreon stream connectors lua modules.

All those parameters are documented here.

Some of them are overridden by this stream connector.

Event bulking

This stream connector is not compatible with event bulking. Meaning that the option max_buffer_size can't be higher than 1

Event format

This stream connector will send event with the following format.

service_status event

Custom event format

This stream connector allows you to change the format of the event to suit your needs. Only the event part of the json is customisable. It also allows you to handle events type that are not handled by default such as ba_status events.

In order to use this feature you need to configure a json event format file and add a new stream connector parameter.

TypeNameValue
stringformat_file/etc/centreon-broker/pagerduty-events-format.json

The event format configuration file must be readable by the centreon-broker user

To learn more about custom event format and templating file, head over the following documentation.

Curl commands

Here is the list of all the curl commands that are used by the stream connector.

Send events

curl -X POST -H 'content-type: application/json' 'https://events.pagerduty.com/v2/enqueue' -d '{"dedup_key":"<my_host>_H","payload":{"component":"<my_host>","group":"<hg_1>","summary":"winter is coming","class":"host","severity":"info","timestamp":"2021-09-24T14:37:22.000","custom_details":{"Hostgroups":"<hg_1>","Hostseverity":2},"source":"<my_host>"},"event_action":"trigger","client":"Centreon Stream Connector","routing_key":"dzada32193dzbe1fz51xz","links":[{"href":"<centreon_url>","text":"Link to Centreon host summary"}]}'

You must replace all the <xxxx> inside the above command with their appropriate value. <my_host> may become linuxServerA.
