Alerts API
Contents
Create alert
POST /v2/alerts/
Path Parameters
name*
String
A name that uniquely identifies this alert.
metric*
String
The graphite metric query to alert on.
alert_criteria*
String
The criteria for which the alert triggers.
additional_criteria
String
Any extra metrics that are to be included when evaluating the state of an alert, these are referred to as Composite Alerts. Note that any additional criteria must be referenced in the expression field and a maximum of 3 additional criteria is allowed. Example: {"f": {"type": "above", "above_value": 5, "metric": "additional.metric.to.alert.on"} where f is also referenced in the expression field. Defaults to {}.
expression
String
A conditional relationship between multiple metrics. It allows for the combining of multiple alert criteria. It’s represented in the format of a boolean expression where each individual alert criteria is denoted as a single letter. The letter a is reserved for the criteria defined in alert_criteria. Only required when additional alerting criteria are defined. Maximum number of 3 additional criteria allowed (4 including the default alert criteria). && takes higher precedence over || Examples: a && b, a || c. Defaults to a.
above_vale
String
The value above which the alert should trigger. Required for alert type above and outside_bounds.
below_value
String
The value below which the alert should trigger. Required for alert type below and outside_bounds.
time_period
String
The time period in minutes for which the threshold needs to be breached. Leave empty for an instantaneous evaluation. Required for alert type missing.
scheduled_mutes
String
List of scheduled mutes for this alert. Must be a list of scheduled mute IDs. Defaults to an empty list.
notification_channels
String
List of notification channels for this alert. This can be a combination of channel names and channel IDs. Defaults to Email me if none exists.
notification_type
String
The type of notification interval for this alert. Options are state_change (['state_change'] or 'state_change' is valid) or ['every', time_in_minutes]. This lets you control how often you want to be notified for an alert. Defaults to ['every', 60] if empty.
info
String
Alert message sent with notifications. Can contain an arbitrary string which may contain a description of the alert, steps to follow or references to documentation.
on_query_failure
String
Controls if a notification is delivered if the graphite function query fails. Only valid for Alerts that have graphite function in the metric field. Defaults to notify. Graphite function query can fail due to timeouts from matching too many metrics, being malformed or if it returns duplicate metrics due to aliasing.
Curl example:
Creates an alert named alert1 for metric test.metric.1 that triggers if the value is above 5 for 2 minutes with the (default) Email me notification type.
Request format:
Alert criteria examples:
Create an alert that triggers if the metric is missing for 10 minutes.
Create an alert that triggers if the metric is above 5.6 ever.
Create an alert that triggers if the metric is below 2.1 or above 5.6 ever.
Create an alert that triggers if the metric is below 2.1 or above 5.6 for 10 minutes.
Composite alerts can evaluate multiple metrics/values, and are defined in the additional_criteria and expression parameters in the request format.
Create an alert when one metric is above 80 and another is below 20.
Create an alert when one metric is below 50 or another is below 30.
Create an alert when one metric (A) is below 50 and another (B) is above 60 or if a third (C) is above 120. Note that performing an && on two monitors gets preference over || so this alert expression will be evaluated as (A && B) || C
NOTE: - Our Alerts UI doesn’t fully support composites so composite alerts can only be created and updated via the API. The alert overview page (when you click the eye button on an alert), will only display one metric for the alert instead of all the metrics associated. However the alert notifications are working and will display the graph of the last metric that breached the alert threshold. So for example, if the alert is a && b, and a breaches the threshold, then a few minutes later b breaches it’s threshold, the alert notification will show the metric graph for b.
Search alerts
GET /v2/alerts/
Returns a JSON object containing information on alerts matching the search query. Returns all the alerts if the parameter is left empty: /v2/alerts/?
Path Parameters
name
String
Format: &name=<alert_name1>&name=<alert_name2>The alert name to search for. Can specify multiple alert names to search for more than 1. Performs an OR operation so a query such as &name=<alert_name1>&name=<alert_name2> will return info on both alert_name1 and alert_name2
id
String
Format: &id=<id1>&id=<alert_id2>The alert id to search for. Can specify multiple ids to search for more than 1. Performs an OR operation so a query such as &id=<alert_id1>&id=<alert_id2> will return info on both alert_id1 and alert_id2.
search
String
Format: &search=<search_string>A more generic search that will match any alert whose alert name, metric name or notification channel name contains the search string.
page
String
Format: &page=1The page number to query. Used if there are more alerts than can be displayed in a single request. (default: 1)
max
String
Format: &max=50The maximum number of alerts to display. Limit of 100. (default: 100)
Curl example:
Returns a list of all alerts
Returns a list of alerts that match the search pattern "example".
Specifying both alert_name and alert_id performs an OR operation and returns alert that match either criteria. Including a search string performs an AND operation with the other criteria.
Search for a single alert
GET /v2/alerts/<alert_id>/
Returns information on a single alert
Curl example:
Obtain information on the alert identified by the id 123-456-7890. The alert id can be found in the URL of the alert when viewed from within the Hosted Graphite Alerts UI. NOTE: a request must contain the forward slash character after the alert_id.

PUT /v2/alerts/<alert_id>/
Update attributes of an alert identified by the alert id
Curl Example
Modify the alert identified by the id 123-456-789 to alert if the metric values are below 6 for 3 minutes. Each field is optional, only the specified fields are updated, and requests must contain the forward slash character after the alert_id.
