Measures reported by GtmServerStTest
A server defines a physical system on the network. If a server is unavailable or down for a longer duration, the traffic manager will not be able to handle the load. To ensure the requests are catered properly, the server should be up and running.
This test auto-discovers the servers in the target BIG-IP GTM, and for each server, this test reports the availability and the status of the server. Using this test, administrators can instantly identify the servers that are not available/error-prone/disabled.
Outputs of the test: One set of results for each server status in the BIG-IP GTM that is being monitored.
