[LARTC] Traffic Control Diagnostic Graphing Utility

[LARTC] Traffic Control Diagnostic Graphing Utility

[Jason Boxman]

I wrote a Perl script to poll `tc` for traffic control statistics (just bytes 
presently) for leaf qdiscs.  The information is fed to either RRDTool or 
Munin[2], depending on what parameter is passed to the script.  If the option 
for a RRD database is used, graphs[3][4] are written to disk for each ten 
second polling interval.  If invoked via Munin[2], it handles graphing and 
samples at five minute intervals.

[3] http://trekweb.com/~jasonb/images/eth0-24-tc.png
[4] http://trekweb.com/~jasonb/images/eth0-1-tc.png

The aim is to graphically represent bandwidth utilization for each leaf class 
to help diagnose issues with misclassification, performance, and for long 
term profiling.

The script is available[5] here.  The included README explains basic 
configuration.

I hope someone else finds it useful.

Comments welcome.

    Hi Jason, 

    I'm trying your script with munin. But I can't make it work. Here you
have the error I get: 

munin-run polltc_eth0
Use of uninitialized value in hash element
at /etc/munin/plugins/polltc_eth0 line 126.
Use of uninitialized value in string eq
at /etc/munin/plugins/polltc_eth0 line 159.

at /etc/munin/plugins/polltc_eth0 line 159.

at /etc/munin/plugins/polltc_eth0 line 159.
Can't use an undefined value as an ARRAY reference
at /etc/munin/plugins/polltc_eth0 line 327. 

	polltc_eth0 is linked to polltc_ as explained in the Readme. And It is
modified to point to /sbin/tc. 

	I'm checking polltc_ to see if something else need to be modified. 

	Best regards.

hi Jason, and thx for your perl script. but i can't do it work. I can't
use perl, so i feel myself an idiot :(

the script answer this error:

Use of uninitialized value in hash element at polltc_eth1 line 126.
Use of uninitialized value in string eq at polltc_eth1 line 159.
Use of uninitialized value in string eq at polltc_eth1 line 159.

Use of uninitialized value in string eq at polltc_eth1 line 159.
Can't use an undefined value as an ARRAY reference at polltc_eth1 line 327.

the Line 126 is:
               $stats{ $id } = {
the line 159 is:
               if( $type eq "root" ) {
and the line 327 is:
               if( scalar( @{ $child_hash{ $foo } } ) > 0 ) {


TIA, Magin Lopez.
