Hi,

I am looking to exchange some notes related to the configuration of the Azure load balancer with K2 Five.

 

Specifically, the K2 farm can interact with users via multiple ports captured via:

https://help.k2.com/onlinehelp/K2Five/ICG/5.3/default.htm#Prepare/Firewall-Settings.htm

 

Outside of obvious ports 80 and 143, how can I configure Azure's load balancer to allow for monitoring and proper load balancing of other ports? Specifically, can I monitor and load balance ports 5555 and 5252?

 

Thanks a lot.

-BJ

Hi bjbier,


 


Maybe the Azure LB health probes can be used in your scenario, it sounds like you might have to create health page check for K2 servers.

Thanks. Azure's load balancer health probes, in this case, seem to be only scratching the surface - we've been running with these probes for a while, however, they fail to detect less frequent but more impactful outages, to be more specific k2 service down situations.  One thing I have not tried to do yet, was to design the health check page. Have you seen anything that could be used as a template? Do you have some ideas what to check for? 

 

Such a page would need to trigger K2 internals so that I'd not confuse IIS responses with responses caused by k2server. I'm sure I could try to reverse engineer some internal asps that are provided by K2, it's just a matter of time.

 

Thanks a lot!
