Grafana / Gateway Service Metrics / Routing Failure

Products

• CA API Gateway

Issue/Introduction

Need to understand why the counter of "routing failure" is never moving in the Grafana graphs even if I am generating errors of this kind.

Can you explain how the tag "isRoutingFailure" is set to true?

We are using the example gateway deployment from :

https://github.com/CAAPIM/apim-charts/tree/stable/charts/gateway

 

Environment

Release : 10.0

Component : API GATEWAY

Cause

The Grafana graphs are using data from influxdb which is receiving metrics data from the gateway using the external metrics .

The API are created from API Portal and are using the default portal policy templates or are using custom policy templates where the routing is done in a custom encapsulated assertion .

Resolution

By default a encapsulated assertion is not propagating the routing statistics to the parent policy , therefore the policy will always be flagged as failed due to policy problem.

If you are doing the routing in a portal published API template which is a encapsulated assertion too or a custom encapsulated assertion you have to set the option "Update routing statistics in parent policy"  in the encapsulated assertion properties . 

This is also not checked for the portal default templates :

- Standard Policy Template - API Key

- Standard Policy Template - No auth

- Standard Policy Template - OAuth.20 .

Right click the policy "Standard Policy Template Fragment - API Key " select  "encapsulated assertion properties " on the bottom of the screen select "Update routing statistics in parent policy" and save it.
