I know that haproxy exposes metrics like „Tr“ and “Tt”. My problem with the application I have to proxy is that this application hides all of her functionality behind one endpoint. To address the app I have to POST to (just an example) https://hpalm/endpoint. The payload that gets POSTed always has this shape:
{ 0: \0000001C\0:conststr:GetServerSettings, .... The string behind „conststr“ is the real API endpoint, there are 10s of different meanings. Is it possible to have haproxy or a “plugin” inspect the POST body, extract the string and create metrics like “Tr” and “Tt” for each of those values ?
