q1 - average failures per second, 5m window:
avg without(job, status)(rate(fulfilment_requests_total{status="failed"}[5m]))q2 - average processed per second, 5m window:
avg without(job, status)(rate(fulfilment_requests_total{status="processed"}[5m]))q3 - average failure rate by instance :
avg without(job, status)(rate(fulfilment_requests_total{status="failed"}[5m])) / avg without(job, status)(rate(fulfilment_requests_total{status="processed"}[5m]))q4 - average failure rate by instance with version:
(avg without(job, status)(rate(fulfilment_requests_total{status="failed"}[5m])) / avg without(job, status)(rate(fulfilment_requests_total{status="processed"}[5m]))) * on(instance) group_left(app_version) app_infoq5- average failure rate by version:
avg without(job, status, instance)(rate(fulfilment_requests_total{status="failed"}[5m]) * on(instance) group_left(app_version) app_info) / avg without(job, status, instance)(rate(fulfilment_requests_total{status="processed"}[5m])* on(instance) group_left(app_version) app_info)Results
You'll see output like this:
| Version | Avg. Failure Rate |
|---|---|
{app_version="1.3.1"} | 0.04880891333737356 |
{app_version="1.5.2"} | 0.1361644759015841 |
Turns out the new version is producing errors at 3X the rate of the old version. Guess we need to rollback the update 🙂
