Real User Monitoring - Service Level Agreement (SLA) Alerting

Alerting based on an Service Level Agreement is robust against single peaks or outliers. You can specify for each self defined group if you want to get notified when an amount of executions are below a defined threshold. The following fields define the behavior:

  • Response Time Threshold [ms] : Enter the value in ms. Default is 3000
  • Percentage: Define how many executions in % should be below the threshold. Default is 94
  • Calculation Frequency [min]: Defines how often the alert should be calculated. Default is 10 minutes
  • Minimum Number of Executions: Define how many executions must be available in the interval. Default is 10
  • Notification Variant: In case someone should be notified you can choose a variant.
  • Outbound Connection Variant: In case something should be triggered automatically you can choose the variant.

The following picture illustrates under which conditions an alert is raised.

 

Starting with SAP Focused RUN 4.0 FP02 you can define additionally under Group Configuration not only dedicated systems but also LMDB Attributes:

  • IT Admin Role: e.g Production System
  • Priority: e.g. Very High, High
  • Lifecycle Status: e.g. Active, Installed
  • Additional Attribute Key: Your own defined LMDB attribute
  • Additional Attribute Value: The value you have entered for that system under the LMDB attribute

All Attributes are AND combined, different values per attribute are OR combined.

Important!

  • If systems are entered only these systems are taken into count for alert calculation.
  • If LMDB Attributes are entered only the systems where all the entered combinations matches are taken into count for alert calculation.
  • If neither system IDs nor LMDB Attributes are entered the alert calculation takes all systems for alert calculation.

 

In the picture above are all Systems selected where

IT Admin role is Production System AND

Priority is Very High OR High AND

Lifecycle Status is Active OR Installed AND

Additional Attribute Location is set

(Attribute Value is not not evaluated because it is empty)

Starting with SAP Focused RUN 4.0 FP02 you can define additionally under the SLA configuration to  

  • Raise Alert per System: If multiple system have been entered or LMDB Attributes for each system a separate alert is raised
  • Raise Alert per Request: If multiple requests have been entered or wildcards a separate alert is raised for each matching request name.
  • No Auto Confirmation on Green Alert: The alert is not automatically confirmed for a green calculation event.

Important!

Be careful with using Raise Alert per Request, Raise Alert per System and LMDB Attributes or without defining a system. This might create many different alerts.

 

Some hints:

  • Mixing different request types usually makes no sense, because they have different response time ranges. Front-end requests are usually around some seconds whereas back-end requests are around hundreds of milliseconds.
  • Limit the amount of possible alerts by entering values as precise as possible. Wild cards are allowed but too generic values could create too many alerts.
