Document for API performance on the endpoints dashboard

This document is for basic knowledge of GCP monitoring of API performance on endpoints.

We will cover two topics related to GCP monitoring of API performance.

We need to login on to GCP https://console.cloud.google.com/
We need to select our project from the top left side. For eg : esb-platform-staging
After that search Endpoints on search bar and select Endpoints.

After that select the service in which your endpoints have deployed. For eg: building-blocks-dot-esb-platform-prod.appspot.com

In the overview dashboard, you will see various graphs like (Request, Error, Total latency, etc) in some time frame.
You can select one time frame and your selected graph will show all information within that time frame.

After selecting of time frame, you can see how many request hits came on your endpoints and also able to see how many 4xx, 5xx and latency came on your endpoints.

You can get all information related to your endpoints.
There is one more section that Deployment History, In which you can check which endpoints are deployed on the server.

You can also track the deployment of endpoints according to configuration IDs.
New configuration ids will create on every new deployment.
After selection of any configuration IDs, you can able to compare endpoints of deployment with older endpoints version.
Sometimes you may replace endpoints due to wrong deployment but still, you can able to access old endpoints due to caching implemented on the GCP side, but after some time you will get error like ‘’Backend error”, so you can check your endpoints with current deployment endpoints.

2. Steps for Endpoints monitoring-

Search the App engine on the GCP console search bar and select App engine.

After that select the service for which service you want to see performance. For eg: building-blocks

Then you can select the chart setting, from which you can see graph of server latency, traffic, instances, error, etc within the selected time.
You can change the time frame and performance will show on your selected graph.
After scrolling down, you will see the Application errors chart, from which you can how many errors have come in the selected time on your service.

After selecting any error you will redirect to the error reporting dashboard, and then you will able to see the occurrence of that error when it comes to your service. Also, you can redirect to logs for selected errors.

If Jira is connected GCP project, then you will be able create bugs from here as well with required log details.
After scrolling more on the App Engine dashboard, you will see the current load on the server endpoint-wise.
