Viewing Alerts in Falcon
Falcon provides alerting for a variety of events to let you monitor the health of your
data pipelines. All events are logged to the metric.log file, which is installed by
default in your $user/logs/ directory. You can view the events from the log
or capture them using a custom interface.
Each event logged provides the following information:
Date: UTC date of action.
Action: Event name.
Dimensions: List of name/value pairs of various attributes for a given action.
Status: Result of the action. Can be FAILED or SUCCEEDED (when applicable).
Time-taken: Time in nanoseconds for a given action to complete.
For example, a new process-definition alert would log the following information:
2012-05-04 12:23:34,026 {Action:submit, Dimensions:{entityType=process}, Status: SUCCEEDED, Time-taken:97087000 ns}Table 2.5. Available Falcon Event Alerts
