HAProxy Stats Test
This test monitors each proxy service associated with the target Proxy server and for each proxy service, reports the status, session utilization, session related statistics such as current sessions, maximum sessions, errors that were detected etc. Using this test, administrators can easily figure out processing bottlenecks and rectify the same before the users complain of slow responsiveness of the proxy server.
Target of the test : A HA Proxy server
Agent deploying the test : A remote agent
Outputs of the test : One set of results for every proxy service of the target HA Proxy server being monitored
