In version 13.1, the ILXLogger class was added to expand the ability to log from iRules LX. The API details have been added to to the wiki but in this article, I’ll add context and an example to boot...

Really good post and good to know HSL logging supported in iRules LX, thanks Jason, I’m curious though. HSL was built in TMM because it’s better at shifting packets in TMM than in the Linux kernel. As iRules LX runs in the control plane, are the HSL messages sent back over the RPC channel to TMM? Is there any significant overhead and how are messages handled that maybe processed asynchronously by node.js? Do they have a sequence number or something, otherwise messages risk arriving out of order. (Sorry for the long winded question... it’s friday night and clearly I should have better things to be doing!!)
