[ixpmanager] Getting IXP Manager Sflow integration up and running

[Thorleif Wiik [BCIX]]

Hi all,

just working on the IXP Manager sflow integration.

Recently, I added a couple (not all) peering ports on some switches to send
sflow data
to the collector (which is currently on the same box as the IXP Manager
installation to see how it all work together).
Mac-Adresses are in the Database via the update-l2database.pl script.
For port-channels I inserted the Mac-Adresses via sql. More config details
see below

Then I started   $app/tools/runtime/sflow/sflow-to-rrd-handler
which is running for a couples of days, now.
I see new files to be generated in /var/www/ixpmatrix directories.

e.g.

/var/www/ixpmatrix/ipv4/bytes/p2p/src-00001/

..
-rw-r--r--  1 root root 185312 Sep 29 11:20
p2p.ipv4.bytes.src-00001.dst-00002.rrd
-rw-r--r--  1 root root 185312 Sep 29 11:20
p2p.ipv4.bytes.src-00001.dst-00003.rrd
-rw-r--r--  1 root root 185312 Sep 29 11:20
p2p.ipv4.bytes.src-00001.dst-00008.rrd
-rw-r--r--  1 root root 185312 Sep 29 11:20
p2p.ipv4.bytes.src-00001.dst-00013.rrd
..


Questions:


 a. P2P Graphs (currently my main issue):

When I look on the  IXP Manager Web Frontend now, I still see
_no_ graphs in the p2p section of each peer. Just looking on these,
which I switched sflow to "on" on the regarding switch ports.


Anything I forgot to install or configure for that ?



 b. PeeringMatrix

There might be a missing sflow BGP listener for that, can I have bit more
information on that?

Currently, when clicking on PeeringMatrix, I receive the following mail:

The sflow part of the application.ini like tis:

sflow.enabled = true
sflow.rootdir = /var/www/ixpmatrix
sflow.rrd.rrdtool = /usr/bin/rrdtool
