Nov 20, 2008Disabling Node
Once I disable a node in my pool, how can I tell when all persistent connections have been closed?
The Pool Statistics "Connections" does not seem to show persistent connections.
Thanks,
Drew

- The "STATISTIC_SERVER_SIDE_CURRENT_CONNECTIONS" should display persistent connections. Are you seeing a case where this statistic is returning 0 but you still have active connections to your pool?

Hey Joe,
Thanks for the reply.
I'm not sure how to monitor the variable you mentioned - STATISTIC_SERVER_SIDE_CURRENT_CONNECTION.
Is this via the command line interface?
Sorry,
Thanks,
Drew - Don_MacVittie_1Historic F5 AccountHey Drew,
The best iControl way is by calling get_statistics() on the node object, then looping through the result set looking for the statistic with that name.
Hope that helps!

Hi guys,
Anyway to get this information (STATISTIC_SERVER_SIDE_CURRENT_CONNECTION) from the web interface or web console?
I'll fire up the SDK and write something if there is not.
Thanks,

Is that all server_side current connections? That can be viewed with bigpipe global show all from the web console - JRahm

scratch that, didn't read the thread above... b node all show all reveals the node specific statistics in the web console, and all node stats would be server side. - Drew_82635

Hey elah,
I tried both commands - thanks for the reply!
I don't believe either one is returning Static/persistant connection information.
I know the F5 is maintaining persistent connection information because my browsers continue to connect to the same web server they initially talk to even when the "conns (cur, max, limit, tot) = (0, 30, 0, 53000)"
I can get conns (cur, max, limit, tot) = (1, 30, 0, 53000)" if i run the node all show all command right as the browser is connecting to the webserver.
What I'm looking to do is insure no browsers have persistent connections before I turn off a node.
Thanks for your help,

bigpipe persist all show all will show you all the entries if present (under a certain number of entries)
bigpipe persit node show all will show you the entries if present for a particular node
bigpipe persist help will give you all the combinations of options. You can always delete them all as well with bigpipe persist all delete - Drew_82635

That is exactly what I needed.
Now I just have to figure out why it returns:
PERSISTENT CONNECTIONS --
No persistent connections were found.
Very odd, I'll do some searching.
Thanks so much for your help,

Argh.
