Error 400

Non è indicato alcun file del repository né alcun test. Inizia tracciando il metrics scraper attorno all’endpoint di login mostrato nei log e riproduci la risposta HTTP 400 su un LTM interessato; il lavoro è completato quando l’autenticazione rimane affidabile e le metriche continuano a essere raccolte.

This issue is happening on about half of our LTMs. We thought changing the username to a new one was a workaround, but it doesn't work consistently. We are able to get metrics from these systems for some period of time until we start getting these errors and no longer get metrics.

Since the logs don't show information on what LTM has the issue, we use a script to capture that information and place it in the log; thus the LTM name on each line.
