Leif Hedstrom commented on TS-4741:
-----------------------------------
Maybe this can be piggybacked somehow of the future plumbing of the Lua
Scriptles (what I call "Lua Crooks" :-)? Basically, attach a co-routine from a
logging State to the HttpSM? Or some such.
> Emit logs with native Lua functions

> Key: TS-4741
> URL: https://issues.apache.org/jira/browse/TS-4741
> Project: Traffic Server
> Issue Type: Improvement
> Components: Logging
> Reporter: James Peach
> Fix For: sometime
>
>
> Starting with TS-4548, we have Lua configuration for setting up logging
> objects. The next step is to find a way to let operators write a Lua function
> to generate the actual log lines. This would let you perform log filtering,
> etc. in Lua and make arbitrary calls to Lua functions when generating the log
> entries.
> To get this to work, the main challenges are Lua state management (one state
> per loggin thread maybe? how would config reload work?) and the API around
> exposing logging tags (magic table indexes named after the tags?).
