Overview

The Sensu VictorOps Handler is a Sensu Go Handler for sending events to the
VictorOps incident response platform.

As of the initial version (0.1.x), this is meant to work in the same fashion as
the prior Ruby based plugin, sensu-plugins-victorops, with the following
changes:

• The environment variables for routing key and API URL are now
  SENSU_VICTOROPS_ROUTINGKEY and SENSU_VICTOROPS_APIURL, respectively
• Since Sensu Go events do not have an action, the RECOVERY message_type is
  based on event.check.status == 0

Configuration

Asset registration

Sensu Assets are the best way to make use of this plugin. If you're not
using an asset, please consider doing so! If you're using sensuctl 5.13 with
Sensu Backend 5.13 or later, you can use the following command to add the asset:

sensuctl asset add nixwiz/sensu-victorops-handler

If you're using an earlier version of sensuctl, you can find the asset on the
Bonsai Asset Index.

Templates

provided by the event in the message sent via SNS. More information on
template syntax and format can be found in the documentation.

Environment variables

Security Note: Care should be taken to not expose the routing key for this handler by specifying it
on the command line or by directly setting the environment variable in the handler definition. It is
suggested to make use of secrets management to surface it as an environment variable. The
handler definition above references it as a secret. Below is an example secrets definition that make
use of the built-in env secrets provider.

type: Secret
api_version: secrets/v1
metadata:
  name: victorops_routingkey
spec:
  provider: env
  id: SENSU_VICTOROPS_ROUTINGKEY

Argument annotations

All arguments for this handler are tunable on a per entity or check basis based on annotations. The
annotations keyspace for this handler is sensu.io/plugins/victorops/config.

NOTE: Due to check token substituion, supplying a template value such
as for message-template as a check annotation requires that you place the
desired template as a golang string literal (enlcosed in backticks)
within another template definition. This does not apply to entity annotations.

Examples

To change the message template for a particular check, for that check's metadata add the following:

type: CheckConfig
api_version: core/v2
metadata:
  annotations:
    sensu.io/plugins/victorops/config/message-template: "{{`{{.Entity.Name}}/{{.Check.Name}}: {{.Check.State}}, {{.Check.Occurrences}}`}}"
[...]
