My previous post has presented an hidden command for analysing in real time fabric statistics. I've developed a small op script, for the MX platform, that provides in one command the PFE/Fabric IN/OUT statistics for all the Fabric Planes (0 to 5) for a given DPC/MPC.
During stress tests it could be very useful :) At least, for me !
The 'op' script is called fabstats.slax. It has been tested with release 10.2 and 11.4. You can simply download it : here
After that, just upload it in the directory /var/db/scripts/op/ of your MX and activate the script by entering the following command :
edit exclusive
set system scripts op file fabstats.slax
commit sync and-quit
Now we can play with it:
sponge@bob> op fabstats ?
Possible completions:
<[Enter]> Execute this command
<name> Argument name
detail Display detailed output
fpc Specify fpc slot number
| Pipe through a command
You must provide 1 parameter :
- fpc : fpc slot number
Hereafter one sample output :
sponge@bob> op fabstats fpc 2
