Ok..I'm going down a road that I KNOW some of you have travelled before, I need your travel tips. We are setting up a server group on 7.5 Windows and we are putting a load balancer in front of it. How do you all tell if a node is up? There are 4 types of probes that I'm being told are available.
PING HTTP TCP Script Ping - Obviously doesn't tell you anything other than the host OS is up HTTP - Won't work for telling if a remedy service is up TCP - My instincts are telling me that this one simply does something similar to a telnet to a given port, if the port allows you 'in', then the service is considered up. I don't consider this one viable because it doesn't 'test' much and I expect that my remedy server could respond to the port request without actually being functional Script - This one is the most promising in my mind, but I know nothing about the scripting language of TCL. How does the rest of the remedy world 'verify' that their remedy instance is online so that their load balancer can know to route traffic to it or not. I just this week finished a java servlet that allows the mid tier load balancer to know if an individual node is working properly, but the same can't be said yet for Remedy..any and all help is appreciated _______________________________________________________________________________ UNSUBSCRIBE or access ARSlist Archives at www.arslist.org attend wwrug11 www.wwrug.com ARSList: "Where the Answers Are"
