ServiceNow

ENTERPRISE: Built-in integrations are available for Sensu Enterprise users only.

Overview

Create ServiceNow configuration items upon Sensu client registration, create/resolve ServiceNow incidents, and/or create ServiceNow events for Sensu events.

Configuration

Example(s)

The following is an example global configuration for the servicenow enterprise event handler (integration).

{
  "servicenow": {
    "host": "dev42.service-now.com",
    "user": "admin",
    "password": "secret",
    "create_cmdb_ci": true,
    "cmdb_ci_enabled": true,
    "cmdb_ci_table": "cmdb_ci_server",
    "incident_management": true,
    "incident_table": "incident",
    "timeout": 10
  }
}

When creating ServiceNow configuration items, by default, Sensu will use the client’s name for the item name. Individual Sensu clients can override the name of their corresponding configuration item, using specific client definition attributes. In addition to specifying a item name, any valid CMDB table attributes (fields & values) may also be set, e.g. os_version.

The following is an example client definition, specifying its ServiceNow configuration item attributes.

{
  "client": {
    "name": "i-424242",
    "address": "8.8.8.8",
    "subscriptions": [
      "production",
      "webserver"
    ],
    "servicenow": {
      "configuration_item": {
        "name": "webserver01.example.com",
        "os_version": "14.04"
      }
    }
  }
}
