GTM sorry server/last resort best practices

 

Do your GTMs monitor the LTM using the "bigip" monitor?

 

If so, the LTM will report the status of all its virtuals to the GTM syncgroup. (You don't need the GTMs to fire a separate HTTP health check at the LTM virtual server.)

 

 

After this, all you have to do is ensure that your LTM health checks appropriately mark the poolmembers up/down when they are available/unavailable. Given a properly functioning GTM syncgroup (emphasis on properly), if the virtual is Red on the LTM, it will be Red on the GTMs too.
