Feature/node stats

[cgunning]

Adds stats for node. I had to change interval in LBNodeFQDN from int to string. Could it be a version issue and that they've changed this?

[cgunning]

Ok. I've failed somewhat with my branches and pull requests. Sorry about that

@cgunning Don't mind the pull requests - I appreciate the help/effort and extra features. Thanks! My F5 certainly has interval in Node FQDN as an int. I have version BIG-IP 11.6.0 Build 5.0.429 Hotfix HF5.
I'll see if mine breaks now.

@cgunning yep - that node FQDN does break now

I'd be interested to know what version of BIG-IP you are running.
Tx.

Ok. That's unfortunate. I'm running version 12.0 so it seems to have been a change there which seems like a bad change to me. For best compability I think it's necessary to take the version into account. I don't know the best way to do this but I'd be happy to cooperate with you to solve this issue

Yep - it is unfortunate. It feels like an error with the v12 software - surely it should be an int??
So for now I have set that field to an interface. Not nice. If you have a better idea - feel free to suggest.
I've raised an issue as a reminder for myself. I may ask F5 when we upgrade ours.
