iControl Rules of Engagement...
Hi
Having written a few application specific iControl monitors for a service's backend servers, I was wondering if there were and F5 recommendations regarding the interval that iControl scripts should be run and what the maximum number of concurrent connections via iControl is ?
The Scenario:
5 Backend servers: A, B, C, D, E
Servers A, B & C have two associated Virtual Servers, but are also dependant on virtual servers associated with D & E.
As A, B & C need to know the status of D & E, the iControl scripts have to check their status before deciding if they need to take any BigIP action.
The application requirements we have mean that we need the fastest possible reaction to (application) failure so as a result, all nodes for the service check their BigIP status (and each others) every 15 seconds.
Operationally this is working well at the moment, but we have an additional three services that require a similar setup and I'm concerned that this could cause BigIP problems.
I apologise in advance if this sounds like a badly written test exam, but I'd appreciate anyone else's experiences / guidance here.
Thanks in advance!!
