Learn how to formulate events() queries.

You use events() queries to display events in charts. An events() query cannot be the only query on the chart; at least one time series must be enabled on the chart in addition to the events() query to display the events.

Event Query Syntax

events([<filterName>=”<filterValue>”] [and|or|not <filterName>=”<filterValue>”]])

where <filterName> is one of the supported event filters.

You can specify multiple event filters separated by boolean operators (and, or, not). You can use a comma instead of the boolean operator and. You cannot create events() queries in the Query Builder.

Example Queries

  • events(name=”Request*” and (severity=”severe” or severity=”warn”)) or events(name=”Request*”, severity=”warn” or source=”app-1”) - Display user events or events based on any alerts that start with Request and are either severity severe or warn.

  • events(severity=”warn” or source=”app-1”) - Display events with severity warn or generated by the source app-1.

Event Filters

Event filters allow you to limit which events are returned from events() queries.

alertId The ID of the alert that created the event. events(alertId=1411189741192)
alertTag A tag associated with the alert that generated the event. events(alertTag="ops")
eventTag A tag associated with the event. events(eventTag="codepushes")
name The name of the event. Manually created events have a unique name, while events generated by an alert have the same name as the associated alert. The name filter requires quotes if spaces exist in the name. events(name="Request Latency too high")
severity The classification of the user event or the severity of alert that generated the event. User event classification levels are severe, warn, info, and unclassified. Although an event can be left as unclassified, the severity filter does not accept unclassified as a valid value. events(severity="info")
source or tag The source or source tag associated with the alert that generated the event. The source filter allows you to display events generated by an alert based on a single source or set of sources. The tag filter works the same way, but allows you to specify a source tag instead of a source name. events(source="app-*" or tag="dc2")
subtype The subtype of event of type alert-detail: failing, recovered. events(subtype="failing")
target The target of the alert that generated the event. The list of targets associated with an alert are considered a single string. If you want to identify a single target within that string, then you must use wildcards. For example, if the notification field contains: john.doe@example.com, jane.doe@example.com, pd:fbw21c9ee0219473w2179r4t23f8c34, to use jane.doe@example.com as the target filter, specify the email as *jane.doe@example.com*. events(target="*jane.doe@example.com*")
type The type of an event. There are system-generated event types: alert, maintenanceWindow, alert-detail, credentials-error, alert-created, alert-updated, alert-deleted, dashboard-deleted, maintenancewindow-created, maintenancewindow-updated, maintenancewindow-deleted and you can optionally assign a type to a user event. The value requires quotes if it contains spaces or starts with a wildcard. events(type="Code push")

Further Information

There are many functions available for operating on the result of an events() query. For examples, see Advanced events() Expressions and for a general reference, see Event Functions.
