NimbostratusGTM Monitor up and Down for HOP load-balancing
Hello,
I have GTM monitoring several servers under one wide up, its using HOP pool load-balancing method, which uses trace-route to find the nearest server, but for some reason the servers which are not under LTM but directly on GTM keeps going up and down, anyone has seen this? could this be a timer issue?

"The Hops load balancing mode is based on the traceroute utility, and tracks the number of intermediate system transitions (router hops) between a client LDNS and each data center. Hops mode selects a virtual server in the data center that has the fewest router hops from the Local DNS."1) Your GTM LB method shouldn't really effect your health monitoring. What health monitor do you have for the generic GTM servers? You may want to do a tcpdump to see the behavior. And also possibly turn on GTM debug and look through "tail -f /var/log/gtm & "tail -f /var/log/ltm"
2) Are the GTM servers that are not under the LTM setup as a generic server?
f5dev7_171984My assumption to use the HOP LB method was because the servers are scattered at different two-location,
1) I will try to that as soon as I get access.
2) Yes they are setup as generic servers.
