Aggregating Dashboard Statistics

Introduction

A customer recently asked how to configure dashboards so that an aggregated average for particular server groups are displayed. Here’s the solution we provided

Update the System Dashboard

Parameters

The parameters section is added to enable filtering by the value(s) you are looking for. In this example, we’ll assume that the serverHosts configured on your platform have a “prod” or “qa” prefix. The “All Environments” label is provided as an all-inclusive default.

Modify the "System" Dashboard

In order to utilize the #environment value from the parameters definition, I replaced all instances of $serverHost=#serverHost# with (#environment).

Conclusion

The new “System” dashboard is provided in its entirety below:

Users can now select the average of all servers, or statistics for a particular subset of servers (as defined in the parameters)

You can add additional constraints as needed -- the value field consists of a valid DataSet search query.

Implement the new System Dashboard

Simply create a new dashboard and paste the (above) configuration in!
