HAPROXY Stats page

Using 1.2.17 if version is relevant..  

Is there a FAQ anywhere?  

I searched the web site, but have not been able to find an explanation for all the counters on the stats page. If documented somewhere, can someone point it out. For the most part, I think I understand most of the non error stats, and half the error stats. Perhaps it's just the abbreviations that are confusing me.

Act. - Active (is the server active)

Bck. - Backup (is the server reserved for backup)

Curr. - Current number of entries in queue or active sessions

Max. - Maximum number of entries in queue or sessions seen so far

Limit - Maximum that Curr./Max. can grow to until incoming sessions are held in queue

Cumul. - Cumulative - How many sessions so far  

Errors:  

Conn. - Connection errors - Was able to find some of this documented. :-)

            Problem: Unable to connect to server because server is at Limit sessions (or minconn if only one server, no other servers have different cookies), and entries in Queue timed out giving error to client

            Possible Resolutions:

Decrease load to this server (add more servers to balance)

Increase limit (maxconn)

Increase contimeout so that sessions can sit in queue longer prior to failing  

Resp. - ?????????? (I see a few non 0 entries, and have no idea????)

Sec. - ??????????

Check - Number of times server failed a host check.

Down - Number of times server went down due to too many check failures    

PS: It would be nice if the check option warned about bad configurations for new users like me:

Setting the same cookie for more than one server. I was expecting it to load balance between the two, but instead no matter the weight, etc... almost everything goes to the first. (Should be stated a little clearer that each server should have a different cookie to be balanced, or no cookie at all).

Setting a minconn with only one server (or two servers with the same cookie) essentially makes it act like maxconn.   Received on 2007/10/06 17:11
