Manually create an alert

Manually create an alert

An alert can be automatically generated or you can manually create an alert. After creating the alert, an event is also created in the Event [em_event] table. Alerts that are manually created are useful for testing purposes.

Before you begin

Role required: evt_mgmt_admin or evt_mgmt_operator


  1. Navigate to Event Management > All Alerts
  2. Click New.
  3. Fill in the fields, as appropriate.
    Table 1. Alert form
    Field Description
    Number If an alert was created as a result of the event, this field contains the unique ID that Event Management generates to identify the alert.
    Source Event monitoring software that generated the event, such as SolarWinds or SCOM. This field has a maximum length of 100. It is formerly known as event_class.
    Node Node name, fully qualified domain name (FQDN), IP address, or MAC address that is associated with the event, such as IBM-ASSET. This field has a maximum length of 100.
    Type Pre-defined event type, such as high CPU, which is used to identify an event record. This field has a maximum length of 100.
    Resource Node resource that is relevant to the event. For example, Disk C, CPU-1, the name of a process, or service. This field has a maximum length of 100.
    Configuration Item JSON string that represents a configuration item. For example, {"name":"SAP ORA01","type":"Oracle"}. CI identifier that generated the event appears in the Additional information field. This field has a maximum length of 1000.
    Location The physical location of the CI.
    Incident The corresponding incident for the alert.
    Description The alert description.
    Message key Event unique identifier to identify multiple events that relate to the same alert. If this value is empty, it is generated from the Source, Node, Type, and Resource field values. This field has a maximum length of 1024.
    Additional Information A JSON string that gives more information about the event. The JSON data is supported for String values only, other value types are not supported. Numbers must be converted to String values by enclosing them in double quotes, for example, this value is not supported: {"CPU":100 } while this value is supported: {"CPU":"100"}. Another example of a valid JSON string is: {"evtComponent":"Microsoft-Windows-WindowsUpdateClient","evtMessage":"Installation Failure: Windows failed. Error 0x80070490"}. This information can be used for third-party integration or other post-alert processing. Values in the Additional information field of an Event that are not in JSON format are normalized to JSON format when the event is processed. For example, assume that the following plain text is in the Additional information field “Connection instance is successful”. When the event is processed, all this plain text becomes one JSON string and might not be useful within an alert. In the resultant alert, this string is in the Additional information field in JSON format, containing the data: {“additional_content”: “Connection instance is successful"}.
    Mandatory. The severity of the event. The value for this field is copied from the event unless the event closes the alert, in which case the previous severity is retained for reporting.
    • Critical: Immediate action is required. The resource is either not functional or critical problems are imminent.
    • Major: Major functionality is severely impaired or performance has degraded.
    • Minor: Partial, non-critical loss of functionality or performance degradation occurred.
    • Warning: Attention is required, even though the resource is still functional.
    • Clear: No action is required. An alert is not created from this event. Existing alerts are closed.
    • Info: An alert is created. The resource is still functional.
    State The state of the alert.
    • Open: The alert requires user action.
    • Reopen: The previously closed alert requires additional user action.
    • Flapping: The alert is receiving a high frequency of identical events from the same source which causes many alert reopenings after a close had been made. User action is required.
    • Closed: The alert is closed and no further user action is required.
    Category Manner in which an alert derives from one or more events. If the alert was upgraded from Fuji, then all updated alerts have the Regular category.
    • Default: Alert that does not derive from any alert rule or event rule transform.
    • Threshold: Alert that derives from an event rule threshold.
    • Regular: Alert that derives from an alert rule.
    Acknowledged A check box that shows whether a user acknowledged an alert.
    Maintenance A check box that shows whether the resource affected by the alert is in maintenance.
    Updated The most recent time that the alert information was updated.
    Knowledge Article The knowledge article associated with the alert, if any.
    Flapping tab
    Flap count The number of times the alert has flapped—that is, has fluctuated between a closed and a non-closed state—within the flap interval since the start time in the Flap start window.
    Flap start window The initial start time to measure the flapping occurrences.
    Flap last update time The last time flapping occurred. This time is the ServiceNow processing time, not the source system time.
    Flap last state The state before the alert entered the flapping state.
    History tab
    Initial event time The time the event that generated the alert first occurred. This time is the ServiceNow processing time, not the source system time.
    Last event time The last time the event that is linked to the alert occurred. This time is the ServiceNow processing time, not the source system time.
    Created The alert creation time.
    Parent The parent alert, if any—that is, any related alerts that have occurred earlier.
    Work notes The additional notes about the alert.
  4. Click Submit.
