  • 1.  Alert Builder

    Hello,

     

    We are really struggling with the Alert Builder.  The Alert Definition and Alert Threshold sections are confusing.

     

    For the Alert Definition, what exactly does the Accumulation Interval mean?

     

    For the Alert Threshold, what exactly does the threshold, alert condition, and threshold evaluated mean?  The Help section over this part is very vague and unhelpful.

    Accumulation defines what will be evaluated against threshold.

    run frequency < accumulation interval

    Then summarized values in accumulation period are evaluated and compared to threshold.

    Hi Brian,
    Remember that even Correlation (Threshold) Alerts are always built to take action based on the results of a query.  I always like to think of them like this:
    "Every N minutes (run frequency), run the Query looking back over the past N minutes (Accumulation interval which can also be read as "NOW -N Minutes").  If the results of the whole query (per report) or any line in the query result (per line) is more than N (Threshold) then send a message to the defined Alert Receivers every N minutes (Notification frequency).

    The Query that you use to power the Alert must have some kind of counter/metric involved.  So a total number of failed logins (with a Count that you added in the Query Builder) or a Total Disk Used (that you include as an Attribute in the Query) or something of the sort.

    Does that help or make it worse?  Let us know!
