Create a query-level monitor

Introduced 1.0

Query-level monitors run the query and check whether or not the results should trigger an alert. Query-level monitors can only trigger one alert at a time. For more information about query-level monitors and bucket-level monitors, see Create monitors.

Sample Request

POST _plugins/_alerting/monitors
{
  "type": "monitor",
  "name": "test-monitor",
  "monitor_type": "query_level_monitor",
  "enabled": true,
  "schedule": {
    "period": {
      "interval": 1,
      "unit": "MINUTES"
    }
  },
  "inputs": [{
    "search": {
      "indices": ["movies"],
      "query": {
        "size": 0,
        "aggregations": {},
        "query": {
          "bool": {
            "filter": {
              "range": {
                "@timestamp": {
                  "gte": "{{period_end}}||-1h",
                  "lte": "{{period_end}}",
                  "format": "epoch_millis"
                }
              }
            }
          }
        }
      }
    }
  }],
  "triggers": [{
    "name": "test-trigger",
    "severity": "1",
    "condition": {
      "script": {
        "source": "ctx.results[0].hits.total.value > 0",
        "lang": "painless"
      }
    },
    "actions": [{
      "name": "test-action",
      "destination_id": "ld7912sBlQ5JUWWFThoW",
      "message_template": {
        "source": "This is my message body."
      },
      "throttle_enabled": true,
      "throttle": {
        "value": 27,
        "unit": "MINUTES"
      },
      "subject_template": {
        "source": "TheSubject"
      }
    }]
  }]
}

If you use a custom webhook for your destination and need to embed JSON in the message body, be sure to escape your quotes:

{
  "message_template": {
    "source": "{ \"text\": \"Monitor {{ctx.monitor.name}} just entered alert status. Please investigate the issue. - Trigger: {{ctx.trigger.name}} - Severity: {{ctx.trigger.severity}} - Period start: {{ctx.periodStart}} - Period end: {{ctx.periodEnd}}\" }"
  }
}

Optionally, to specify a backend role, you can add the rbac_roles parameter and backend role names to the bottom of your create monitor request.

Example request

The following request creates a query-level monitor and provides two backend roles, role1 and role2. The section at the bottom of the request shows the line that specifies the roles with this syntax: "rbac_roles": ["role1", "role2"].

If you want to specify a timezone, you can do so by including a cron expression with a timezone name in the schedule section of your request.

The following example creates a monitor that runs at 12:10 PM Pacific Time on the 1st day of every month.

For a full list of timezone names, refer to Wikipedia. The alerting plugin uses the Java TimeZone class to convert a ZoneId to a valid timezone.

Create a bucket-level monitor

Bucket-level monitors categorize results into buckets separated by fields. The monitor then runs your script with each bucket’s results and evaluates whether to trigger an alert. For more information about bucket-level and query-level monitors, see Create monitors.

Document-level monitors

Introduced 2.0

Document-level monitors check whether individual documents in an index match trigger conditions. If so, the monitor generates an alert notification. When you run a query with a document-level monitor, the results are returned for each document that matches the trigger condition. You can create trigger conditions based on query names, query IDs, or tags that combine multiple queries.

To learn more about per document monitors that function similarly to the document-level monitor API, see Monitor types.

Search for monitor findings

You can use the Alerting search API operation to search the findings index .opensearch-alerting-finding* for available document findings with a GET request. By default, a GET request without path parameters returns all available findings. To learn more about monitor findings, see Document findings.

To retrieve any available findings, send a GET request without any path parameters as follows:

GET /_plugins/_alerting/findings/_search?

To retrieve metadata for an individual document finding entry, you can search for the finding by its findingId as follows:

GET /_plugins/_alerting/findings/_search?findingId=gKQhj8WJit3BxjGfiOXC

The response returns the number of individual finding entries in the total_findings field.

To get more specific results in a findings search, you can use any of the optional path parameters that are defined in the following table:

Path parameter	Description	Usage
`findingId`	The identifier for the finding entry.	The finding ID is returned in the initial query response.
`sortString`	This field specifies which string the Alerting plugin uses to sort the findings.	The default value is `id`.
`sortOrder`	The order to sort the list of findings, either ascending or descending.	Use `sortOrder=asc` to indicate ascending, or `sortOrder=desc` for descending sort order.
`size`	An optional limit for the maximum number of results returned in the response.	There is no minimum or maximum values.
`startIndex`	The pagination indicator.	Default is `0`.
`searchString`	The finding attribute you want returned in the search.	To search in a specific index, specify the index name in the request path. For example, to search findings in the `indexABC` index, use `searchString=indexABC’.

Create a document-level monitor

You can create a document-level monitor with a POST request that provides the monitor details in the request body. At a minimum, you need to provide the following details: specify the queries or combinations by tag with the inputs field, a valid trigger condition, and provide the notification message in the action field.

The following table shows the syntax to use for each trigger option:

Trigger options	Definition	Syntax
Tag	Creates alerts for documents that match a multiple query with this tag applied. If you group multiple queries by a single tag, then you can set it to trigger an alert if the results are returned by this tag name.	`query[tag=<tag-name>]`
Query by name	Creates alerts for documents matched or returned by the named query.	`query[name=<query-name>]`
Query by ID	Creates alerts for documents that were returned by the identified query.	`query[id=<query-id>]`

      ]
  }}]
}

Limitations

If you run a document-level query while the index is getting reindexed, the API response will not return the reindexed results. To get updates, wait until the reindexing process completes, then rerun the query.

Update monitor

Introduced 1.0

When updating a monitor, you can optionally include seq_no and primary_term as URL parameters. If these numbers don’t match the existing monitor or the monitor doesn’t exist, the alerting plugin throws an error. OpenSearch increments the version number and the sequence number automatically (see the example response).
