Usefulness of server ip on Big-IP DNS systems
I am trying to understand on a F5 GTM system, what purpose does the server ip fulfill? Say I am setting up a WideIP that's supposed to return the IP of a generic host. How I'd typically go about it is a.) create a "server" object that corresponds to a DataCenter and then b.) configure virtual servers that are part of this server. The Big-IP system requires an IP address for this 'server' object and it doesn't seem to matter what IP you enter - because ultimately - it's the IP of one of the virtual servers that gets returned as the WideIP anyway. I've set up Generic Host servers with made up IPs and it has still worked.275Views0likes2CommentsGSLB - Monitoring LTM VIP load balancing via iRule
In one of our environments we are configuring a single LTM VIP and load balancing multiple applications via an iRule. We currently have other LTM environments integrated via iQuery with our GTM for GSLB configuration and monitoring. Is there a way to monitor the VIP at the GTM level via iQuery that would give a true back-end pool status? Since, let's say, we are load balancing 100 different applications via a single VIP, if 99 of them went offline, the VIP would still show as ONLINE/GREEN. Or would we even go as far as integrating via iQuery and adding a dependency monitor of the pool itself instead?56Views0likes6Comments
