Measures reported by GtmPoolStatusTest
A pool is a logical set of devices, such as web servers, that you group together to receive and process traffic. Instead of sending client traffic to the destination IP address specified in the client request, the BIG-IP GTM sends the request to any of the nodes that are members of that pool. When members of a pool are unavailable/disabled, they will not be able to receive or process traffic creating unnecessary traffic overloading.
This test auto-discovers the pools in the target BIG-IP GTM and for each pool, this test reports the availability and the status of the pool. Using this test, the administrator can identify the pools that are not available/in error state.
Outputs of the test: One set of results for each pool in BIG-IP GTM that is being monitored.
Outputs of the test: Pool
