# Alerting API

Use the Alerting API to programmatically create, update, and manage monitors and alerts. For APIs that support the composite monitor specifically, see [Managing composite monitors with the API]({{site.url}}{{site.baseurl}}/observing-your-data/alerting/composite-monitors/#managing-composite-monitors-with-the-api).

## Create a query-level monitor

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 [Creating monitors]({{site.url}}{{site.baseurl}}/monitoring-plugins/alerting/monitors/).

#### Example request

```json
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": {% raw %}"{{period_end}}||-1h"{% endraw %},
                  "lte": {% raw %}"{{period_end}}"{% endraw %},
                  "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:

```json
{
  "message_template": {
    {% raw %}"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}}\" }"{% endraw %}
  }
}
```

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"]`.

```json
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": {

      },
      "throttle_enabled": true,
      "throttle": {
        "value": 27,
        "unit": "MINUTES"
      },
      "subject_template": {
        "source": "TheSubject"
      }
    }]
  }],
  "rbac_roles": ["role1", "role2"]
}
```

}
```

If you want to specify a time zone, you can do so by including a [cron expression]({{site.url}}{{site.baseurl}}/monitoring-plugins/alerting/cron/) with a time zone 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.

#### Example request

```json
{
  "type": "monitor",
  "name": "test-monitor",
  "monitor_type": "query_level_monitor",
  "enabled": true,
  "schedule": {
    "cron" : {
        "expression": "10 12 1 * *",
        "timezone": "America/Los_Angeles"
    }
  },
  "inputs": [{
    "search": {
      "indices": ["movies"],

        "size": 0,
        "aggregations": {},
        "query": {
          "bool": {
            "filter": {
              "range": {
                "@timestamp": {
                  "gte": {% raw %}"{{period_end}}||-1h"{% endraw %},
                  "lte": {% raw %}"{{period_end}}"{% endraw %},
                  "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 a message body."
      },
      "throttle_enabled": true,
      "throttle": {
        "value": 27,
        "unit": "MINUTES"
      },
      "subject_template": {
        "source": "Subject"
      }
    }]
  }]
}
```

For a full list of time zone names, refer to [Wikipedia](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones). The Alerting plugin uses the Java [TimeZone](https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/util/TimeZone.html) class to convert a [`ZoneId`](https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/time/ZoneId.html) to a valid time zone.

## Bucket-level monitors

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 [Creating monitors]({{site.url}}{{site.baseurl}}/monitoring-plugins/alerting/monitors/).

```json

## Document-level monitors
Introduced 2.0
{: .label .label-purple }

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 [Monitors]({{site.url}}{{site.baseurl}}/observing-your-data/alerting/monitors/).

### Search the findings index

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

```json
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:

```json
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>]`

#### Example request

The following example shows how to create a document-level monitor:

    }
  ],

                "source": "The Subject",
                "lang": "mustache"
            }
         }
      ]
  }}]
}

```

### 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.
{: .tip}

## Update monitor

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).

OpenSearch increments the version number and the sequence number automatically (see the example response).
