Unable to push metric to Inbound telegraf webhooks from github server


I have my own repository and want to get the notification to telegraf inbound webhooks which I can post it to wavefront

Ex: For pull_ request event
I want to get metric “no of file changed”, “no of file added” “no of open issues” “no of deletion” etc.

I need to know how to configure telegraf.conf to get these all metrics and configure for individual if needed.

Following this link

telegraf inbound webhooks is successfully configured in github server

Snippet how my telegarf.conf configured

#Address and port to host Webhook listener on
service_address = “IP:1619”
path = "/github"
measurement_name = “testing”
* ‘admin’ = event.sender.site_admin bool
* ‘commit’ = event.comment.commit_id string

please let me know what is missing here.
