I've already setup HTTP DataCollector and now my requirement is how can I get these datacollector values in my email alerts.
Once you have your HTTP Request setup, you should also be able to use the same predefined variables to setup a Custom Email. Then you can build a policy which triggers off whatever Health Rule you setup and as the action trigger it to do both your HTTP Request and a custom email.
You might be able to do it a better way, but off the top of my head, this way seems simple enough.
Thanks a lot for your response.
Request you to please explain me step by step how can i find a way of extracting the Data Collector attribute value using predefined/custom template variables.
Thanks a lot in advance.
It should be the same way you did your HTTP Requests, but this document may help:
