Alert based on average operation time metric

Hello

Please suggest how to create alert based on average operation time duration. The number displayed on Application health report. Marked red on attached pic below. I need alarm then this average metric goes up above baseline but not then single or number operations violates threshold or % above baseline.

Thanks and regards,

Igor

Hello @Igor M.

The baseline setting specifies whether to use the average or pinned baselines for the baseline condition. By default, the average source is selected. This option is available only for generic performance, transaction performance, and Citrix performance alerts. It will not work unless the selected baseline type is enabled for that combination of metrics and dimensions.

A comparison mode describes how a metric value should be compared against a threshold value. Have a look on the below link for more insight:

Igor,

If I understood your case correctly, all you need to do is to create two separate alerts:

In alert #1 use Application1 as filter (on application dimension, of course) and set 4s as a threshold (Operation time metric). Alert #2 should look similar, but use Application2 as a filter and 0.4s as a threshold.

To keep your alert consisted with the report, remember to select Application user experience as an alert type.

Best Regards

Jacek

Gents, i think nobody got me right.

Question was, how to define alert on marked on pic metrics. This is second level drill down from standart Application health report.

- If for first app metric > 4 seconds then triger alert

- If for second app metric > 400 mili-seconds then triger alert

Can one explain please.

Hello @Igor M.

You highlighted the software services area in the first screenshot :)

Now you highlighted the application/business unit. So you can try to configure the alert according to the below screenshot and make sure you are using your application name under the dimension filters.

Regards,

Babar

Babar, thank you for helping me. Honestly i dont understand. Could you please elaborate it more?

I compare "Operations time" with average base line and receive alert for every operation that found spefified % above of baseline. But i need to compare Software serice comulative Operation time metric for its baseline. Not every single operation. How to specify comulative Software service Operation time? Metric that displayed in second line of Application health report. Could you suggest.

Hello @Igor M.

Let me know if below informaiton is helpful for you.

Single

If a baseline condition is specified, the current value of the metric is compared with the baseline value multiplied by the baseline multiplier .

Absolute

If a baseline condition is specified, the alert calculates a percentage increase in the actual absolute increment of the metric versus absolute baseline increment . This means that for two subsequent monitoring intervals, we measure the absolute increment in the value of the metric and subtract from it an increment calculated from comparing baseline value for the same monitoring intervals.

Relative

If a baseline condition is specified, the alert calculates a percentage increase in the actual relative increment of the metric versus relative baseline increment . The calculations are similar to those performed for the absolute mode, except that all differences in metric values or in baseline values are relative.
