Re: [mpls-linux-general] MPLS logging

[Michael F. <mic...@el...>]

Thanks James,
This has fixed all my problems.
I was trying to set up LSP's dynamically, as well as get LSP stats back
from a test network we have here.
With the debug running, the speed of the routers (at least interrogating
via mpls commands) was VERY slow.
We also set up the routers with a series of preconfigured LSP's, and
turn them on and off depending on
measured loads.
It was by chance that I peered into /var/log/messages and saw the debug.

The setup went from 15 mins to 13 secs by switching off debug.
The load measuring commands went way down also.

Everything is sweet now.
