How to monitor vRA 8.1 via the api
Hello All,
Hello All,
It’s way too long that a posted a new article. Sorry for that but family comes first. The good news is that I am starting again ;)
This week I discovered 2 interesting api calls for checking the health of a vRA 8.1. deployment with the “:8008/health endpoint”. I thought, this is worth for sharing. So here they come 8-)
The first api call is to validate the health of a vRA 8.1 node:
I my example, I am using Postman to explore the api call.
GET http://pb0vra8va01.flexlab.local:8008/api/v1/services/local
The second api call is to validate the health of a vRA 8.1 cluster:
GET http://pb0vra8va01.flexlab.local:8008/api/v1/services/cluster
For a detailed overview of what kind of services are validated see the below example.
