iRule documentation!?

I'm afraid there is no such documentation at this time. We are working to produce a more complete iRules reference. However, several of the commands you have seen described on this forum are undocumented. These are generally commands that developers have implemented and unit tested, but they were added too late to be included in an official release. It is usually our intention to add them to the next release, but sometimes these things fall through the cracks.

 

 

I will try to answer some of your specific questions.

 

1) There is currently no way to get the status of a single node or pool member from an iRule. This is a little more difficult than it sounds since there are a lot of things that would make a pool member ineligible for an LB pick. It could be disabled, down, over its connection limit, or have a zero ratio.

 

 

2) LB::server pool returns the currently selected pool. Other subcommands include name, addr, port, priority, and ratio. They are fairly self explanatory; however, name returns a list that includes the pool, address, and port.

 

 

Hope this helps...
