Opened: Mar 08, 2018

Severity: 3-Major


A client-side alert that contains a FPS-Username header with a value, but an empty fpm_username parameter - will be reported with "Unknown" username in bigIQ.


Post login client side alerts are missing username (will show as "Unknown" in bigIQ, works well with Alert-Server).


1. post login (alert is sent after submitting username parameter) client side alerts 2. alert-pool points to bigIQ IP (not Alert-Server)


Route all client-side alerts to another virtual server and strip of the empty fpm_username parameter from payload/query-string.

Fix Information

FPS will always send username in the fpm_username parameter in case it was empty and FPS has username value.
