[ixpmanager] peer-to-peer statistics | sFlow

[Vladislav Leontjev]

Hello,

I'm back with some results (had to change IP and *.rrd files dir location):

latest log: http://p.ip.fi/FlLd
visual prnt-src:of vlan graph: https://prnt.sc/n0im4x

----------------------------------------------------------------------------
 /srv/ixpmanager/config/grapher.php
-----------------------------------------------------------------------------

        'sflow' => [
            // show sflow / p2p links on the frontend
            'enabled' => env( 'GRAPHER_BACKEND_SFLOW_ENABLED', false ),

            // for larger IXPs, it's quite intensive to display all the
graphs
            'show_graphs_on_index_page' => env(
'GRAPHER_BACKEND_SFLOW_SHOW_ON_INDEX', false ),

            // where to find the MRTG rrd files
            'root'  => env( 'GRAPHER_BACKEND_SFLOW_ROOT', '
http://10.81.7.10/grapher-sflow/' ),
        ],


------------------------------------------------------------------------
/srv/ixpmanager/.env
------------------------------------------------------------------------
GRAPHER_BACKENDS="mrtg|sflow"
GRAPHER_BACKEND_SFLOW_ENABLED=true
GRAPHER_BACKEND_SFLOW_ROOT="http://10.81.7.10/grapher-sflow"
GRAPHER_ACCESS_CUSTOMER=0
GRAPHER_ACCESS_P2P=1

----------------------------------------------------------------
Files have been gathered as it should be;
#/var/www/ixp_p2p/ipv4/bytes/p2p/src-00001$ ls
p2p.ipv4.bytes.src-00001.dst-00003.rrd

I have got 2 peering ports UP and till now 2 rrd files accordingly;
will leave "./sflow-to-rrd-handler --macdbtype=configured" for sometime
to gather more of them;

------------------------------------------------------------------
local install of apache: added lines (used apache the same which was
installed with IXP manager)
------------------------------------------------------------------
/etc/apache2/apache2.conf

Alias /grapher-sflow /var/www/ixp_p2p
<Directory "/data/ixpmatrix">
        Options None
        AllowOverride None
</Directory>
----------------------------------------------------------------
shows the content of /var/www/ixp_p2p with all of its subdirs
http://10.81.7.10/grapher-sflow/
visual prtn-src:of apache  https://prnt.sc/n0ijkk

-------------------------------------------------------------
/usr/local/etc/ixpmanager.conf
-------------------------------------------------------------

<sql>
        dbase_type      = mysql
        dbase_database  = ixpmanager
        dbase_username  = ixpmanager
        dbase_password  = *
        dbase_hostname  = 127.0.0.1
        #dbase_portname = /tmp/mysql.sock
</sql>

<ixp>
        sflow_rrdcached = 0
        sflowtool = /usr/local/bin/sflowtool
        sflowtool_opts = -4 -p 6343 -l
        sflow_rrddir = /var/www/ixp_p2p
#       debug = 1
        apikey = *
        apibaseurl = http://10.81.7.10/api/v4
        macdbtype = configured
</ixp>

Do I understand wright:

1. If I see some page NOT with "dummy" and NOT with "no image found" it
means it's normally tries to interpreter sflow
converted *.rrd's? -> visual prtn-src:of vlan graph: https://prnt.sc/n0im4x

2. As far as there will be enough *.rrd files the graph
visual prtn-src:of vlan graph: https://prnt.sc/n0im4x
will be shown with in/out statistics at the bottom as it should be?
3. GRAPHER_BACKENDS="mrtg|sflow" - tries to use mrtg -> failed -> then
sflow?
4. from log means: production.ERROR: No backend available to process this
graph
It's because of mrtg is not installed?
5. Do I understand documentation in a wright way: Overall peering graph is
available only by mrtg? I need to implement it too them?

Thank you.

Vladislav.
