Monitoring Alert Execution through the humio-activity Repository

The humio/activity package provides a wealth of information about activity within LogScale and should be installed to help monitor alerts.

Examine the category field in the humio-activity repo to track progress and any errors generated when executing alerts.

The status field indicates either a Success or Failure. Repeated entries with a failure indicate an error should be investigated.

There are three different Success scenarios for Legacy Alerts:

  • LogScale successfully polled the alert query, found events to trigger on, and successfully triggered at least one of the associated actions

  • LogScale successfully polled the alert query, found events to trigger on, but the alert was throttled

  • LogScale successfully polled the alert query, but found no events to trigger on

For filter alerts, the following scenarios indicate Success:

  • LogScale successfully polled the alert query, found events to trigger on, and successfully triggered at least one of the associated actions

  • LogScale successfully polled the alert query, but found no events to trigger on

The subCategory then indicates whether the event relates to the execution of the Alert, Query, or Action.

Checking the severity field will indicate the level of the event:

  • Info entries are used to indicate when an alert has been triggered or other informational messages. No action is required.

  • Warning indicates an issue either with the alert, reading the result, or triggering actions, or where an alert has not been triggered due to throttling. In some cases, the warning resolves on its own. But if the message persists, it may require action.

  • Error indicates an error, for example running the query or trigger. Requires action.

The following additional fields in each event contain more detailed information for each alert invocation or error; for a full example event, see Alert Raw Event Example:

Field Description
actionId ID of the triggered action; only set for the invocation of a specific action
actionIds List of action ids for when an alert trigger has been triggered
actionInvocationId Unique id for the invocation of an action, can be used to correlate logs, same commenas for actionId
actionInvocationIds List of action invocation ids for when an alert has been triggered
actionName Name of the action that generated an error or would have been triggered
actionName Name of the triggered action; only set for the invocation of a specific action
alertId ID of the alert
alertName Name of the alert
alertTime The timestamp when the alert was triggered.
dataspace Name of the repository or view
eventId The eventId when an alert trigger on an event
events The number of the events returned by the query; by default all queries return a maximum of 200. Where no events were returned by the query the value will be 0.
eventsToTriggerOn When polling a filter alert query
exceptionMessage A detailed error message that will include errors at the cluster-level that may have contributed; for example permission, API, or network issues
externalQueryId The external id of the running query
lastAlertTime The timestamp of the last time the alert triggered
message The error or warning message for the alert
query The alert query executed
queryProcessedEvents The number of events processed to return the final result set.
queryTimeMillis Time in milliseconds since the underlying live query of the alert has been started.
status Indicates whether the alert was successful (value Success) or failed (value Failure). An individual failure may be triggered for multiple reasons, but repeated failures over a period of time may indicate a problem that needs investigation.
suggestion A guide to the warning or error and how to resolve or identify more information
user The user the query runs on behalf of (run-as-user)
viewId ID of the view for the alert
Alert Errors and Resolutions

When investigating errors to identify issues, make use of the message and suggestion fields to provide guidance on why an issue has occurred. The list below describes each message type.

Table: Filter alert errors and solutions

MessageSeverityDescriptionSolution
Problem invoking action. If all actions fail, they will be retried Error There was a problem invoking the alert's actions and all actions failed. In order to be successful, at least one action must trigger on an alert. The alert is not considered to have triggered and will not be throttled. Check the logs for the invoked actions if unsure which action failed. Check if there are any problems with the action targets, such as e-mail server down, pager service down, and so on.
Polling alert query resulted in an error Error The alert query produced an error. This can be due to many different reasons. Look at the message in the exceptionMessage and consult documentation based upon that for possible solutions.
Starting alert query resulted in an error Error The query returned an error when starting. This is usually because of an error in the query. Look at the message in the exceptionMessage field and consult documentation based upon that for possible solutions. Contact LogScale Support for assistance if needed.
An event from the alert query does not contain @id or @ingesttimestamp Error The alert query has removed the @id or @ingesttimestamp fields. This is needed for the alert to be able to run. Check the alert query definition and edit it so that it preserves @id and @ingesttimestamp , if needed. For more information about how to do this, see Editing an Alert.
Triggering on event did not succeed within retry limit, it will not be retried further Error There was an action error and the value in the configurable FILTER_ALERTS_MAX_CATCH_UP_LIMIT parameter has been reached. It will not attempt to trigger the action further. Check the specific errors or warnings from invoking actions. If needed, contact LogScale Support for assistance.
Could not start alert query since it is blocked Error The alert query cannot run since it is blocked. Either rewrite the alert query so it is no longer blocked, or check with the system administrator and remove the query from the blocklist. If using LogScale Cloud, this error can occur if the cluster is in a maintenance window.
Did not start historic query to catch up since ingest is too far behind Error Data is behind because ingest has not caught up. So the historic query on older data cannot run. Look at other logs from the alert to see if there are any errors or warnings, or check whether there are other problems with LogScale.
Alert is too far behind. Will skip events that are older than the catch up limit Error Data older than X hours based on the configured value in the FILTER_ALERTS_MAX_CATCH_UP_LIMIT parameter will not be considered in alert results. Look at other logs from the alert to see if there are any errors or warnings, or check whether there are other problems with LogScale.
There has been a query warning that some events are unavailable for more than ${limit}. These events will now be skipped Error Some events have been unavailable for more that the configured amount of time for the cluster. If there were events that may have produced results, these events were skipped during query execution. Look at the query warning. Run query manually, if needed. Check cluster performance.
The alert is broken Error The alert configuration prevents the alert from running. Edit the alert, check all fields and queries, and save it again. For more information about how to do this, see Editing an Alert.
The alert is not assigned to run on any node Error The alert is not assigned to run on any nodes. Alerts are distrubted evenly among the nodes in a cluster, so that each one runs on a single node. Reassignment of nodes on which alerts run occurs automatically when new cluster nodes are added or old cluster nodes are removed. If the alert does not run on another node after 15 minutes, contact LogScale Support.
Cannot run ${triggerType.toLowerCase}. ${triggerType} was saved by a user that does not exist anymore. Change the alert to run as a different user or on behalf of the organization. Error The user attempting to execute the query no longer exists in the system. Save the alert as a user that exists in the system, or change the alert to run on behalf of the organization. For more information about how to do this, see Editing an Alert.
Cannot run ${triggerType.toLowerCase}. ${triggerType} was saved by a user that no longer has read permission on the view. Grant the user permission again, or change the alert to run as a different user or on behalf of the organization. Error The configured user no longer has read access to the view or repository. grant the user read permissions on the repository or view that the alert is running in, or save the alert with a user that has such permissions or to run on behalf of an organization.

Starting alert query in previous run has not finished. The alert will not be polled in this run Warning The alert query starting did not finish in the previous run, so it cannot be polled in the current run. None. This message is informational. If the problem continues, you can disable the alert, wait one minute, and enable the alert. NOTE: If you do this you may lose results.
Starting the alert query has not finished. The alert will not be polled in this run Warning Query is submitted but has not finished initial loading. None. This message is informational.
Discarding values for field-based throttling. The alert might trigger again before the throttle period expires Warning Maximum amount of field values for throttling has been reached. Once exceeded, the older values are discarded and can produce alerts again even though they are within the throttling period. The values for field-based throttling are set in the following field based on the alert type: ALERT_MAX_THROTTLE_FIELD_VALUES_STORED. For more information about field-based throttling, see Field-Based Throttling. If possible, use a field that produces a smaller amount of different values.
Unknown action Warning The alert contains an unknown action. Edit the alert, remove the action, and add a different action.
Polling encountered a cancelled query Warning The query was cancelled before execution could complete. The cancelled query will be restarted automatically. If the problem persists, contact the system administrator.
Polling alert query in previous run has not finished. The alert will not be polled in this run Warning The alert query did not finish in the previous run, so it cannot be polled in the current run. None. This message is informational. If the problem continues, you can disable the alert, wait one minute, and enable the alert. NOTE: If you do this you may lose results.
Query uses functionality scheduled to change in an automation breaking way Warning The query contains some functionality that may break the alert after a coming release.

The system will stop live queries and start running historic queries to catch up. None. This message is informational. If the isLiveQuery field never reverts to true, contact the system administrator.
Filter alert received too many events. It will only trigger on ${state.triggerLimit} per ${FilterAlertJobImpl.QueryBucketSpan} Warning The alert resulted in too many events and cannot trigger all events. The query is likely too broad. If this was unexpected, rewrite the alert query to produce fewer results. For more information about how to do this, see Editing an Alert.
Filter alert did not trigger. Trigger limit of ${state.triggerLimit} per ${FilterAlertJobImpl.QueryBucketSpan} has already been reached Warning The alert resulted in too many events and cannot trigger all events. The query is likely too broad. If this was unexpected, rewrite the alert query to produce fewer results. For more information about how to do this, see Editing an Alert.
Alert failed triggering on event Warning There was a problem triggering the alert's actions. In order to be successful, at least one action must trigger on an alert. The alert is not considered to have triggered and will not be throttled. Check the logs for the actions if unsure which action failed. Check if there are any problems with the action targets, such as e-mail server down, pager service down, and so on.
Unknown query warning. The alert will trigger for available events Warning The alert encountered an unknown query. This occurs if, for example, if LogScale is being upgraded. The alert will trigger for the available events but not for any events that might be the result of the unknown query. Look at the warning in the warning field for more information.
