The Comparison panel is meant to display the difference of a current set of values and
the set of values right before, with the same time range.
When the current time range is for example from now-5m to now, the previous time range
(the one to compare with) should be now-10m to now-5m. To achieve this easily, use
the ${__range} variable for current and offset ${__range} for previous values as seen
in the table below.
| Query name | query |
|---|---|
| total-filtered | increase(application_total{status="success"}[${__range}]) |
| total-right-filtered | increase(application_total{status="timeout"}[${__range}]) |
| previous-filtered | increase(application_total{status="success"}[${__range}] offset ${__range}) |
| previous-right-filtered | increase(application_total{status="timeout"}[${__range}] offset ${__range}) |
The query names are mandatory.
