Add a flag to Alert Definitions to "ignore live values"

Solution In Progress - Updated -

Issue

  • Live values will cause false alerts when alert is configured to use dampening rules;
  • An alert that should be triggered only if certain metric value is collected a certain number of times in a row will be falsely triggered if someone navigate to the metric page in JBoss ON UI;
  • Add a flag to Alert Definitions to "ignore live values"

Environment

  • Red Hat JBoss Operations Network (ON) 3
  • An alert is defined to be triggered if metric value is equal to 0 a certain number of times consecutively - for instance:
    • Imported process that is executed periodically - for instance once per hour;
    • Every time, process is properly executed value for the metric Invocation per Minute is lager then 0;
    • In between two execution of the process, the value of Invocation per Minute is 0;
    • Collection period for Invocation per Minute is set to 20 minutes;
    • An alert is defined to be triggered only if Invocation per Minute value is equal to 0 four times in a row (meaning that there was a problem and process was not properly executed);
