I've set a connection limit for a cluster node, which triggers periodically. It looks like this:
01200017:4: Warning, pool member IP 220.127.116.11 port 80 for pool /PR/eeee.com has reached its connection limit.
Now, how can I determine the number of unique users denied by this limit? Thank you.
You could go with LB_FAILED event and capture the required info via loggings.
LB_FAILED do gets triggered when connection limit is increased.
Later use the logs and figure out your unique source ip's or if logs are forwarded to some external app's like splunk, filter it there to find the unique sources.
You can display LTM connexions with the TMSH command show sys connection, more details in links below :
