Sure, In fact you only have to modify the script to add your servers....
For the moment it is hardcoded :) a little ugly I know :) But still very
easy to add new servers.

Both MRTG & RRDTOOL are supported. Anyway all that you have to do if you
want to move to rrdtool is download/install rrdtool, and read quickly the
INSTALL file present into the using-RRDTOOL/ directory. Still very
simple...
The 3 steps are :
1. Creating a RRDtool database for storing your servers value : for exemple
: (script : lvsgsp.dbcreate.RS)
rrdtool create $DB \
DS:www1:GAUGE:600:U:U \
DS:www2:GAUGE:600:U:U \
DS:www3:GAUGE:600:U:U \
RRA:AVERAGE:0.5:1:600 \
RRA:AVERAGE:0.5:6:700 \
RRA:AVERAGE:0.5:24:775 \
RRA:AVERAGE:0.5:288:797 \
RRA:MAX:0.5:1:600 \
RRA:MAX:0.5:6:700 \
RRA:MAX:0.5:24:775 \
RRA:MAX:0.5:288:797
=> Will create a database to store values on www1, www2 & www3. If you have
more than 3 servers, simply append line
2. Update the database created : (lvsgsp.daily.rs)
rrdtool update $DB N:$WWW1:$WWW2:$WWW3
=> append new value to rrdtool database.
3. Create graph
$RRDTOOL graph $OUTPUT --start -86400 \
-w 550 -h 150 \
-v "Connection Number" \
-t "LVS realserver actives connections tracking : Daily report" \
--alt-autoscale-max \
COMMENT:"Current actives connections - $TIME\n" \
DEF:web1=$DB:www1:AVERAGE \
DEF:web2=$DB:www2:AVERAGE \
DEF:web3=$DB:www3:AVERAGE \
LINE1:web1#FF0000:"Webserver 192.168.6.2" \
LINE1:web2#0000FF:"Webserver 192.168.6.3" \
LINE1:web3#555555:"Webserver 192.168.6.4"

Usage: lvsgsp [[-v vsipaddr vsport]|[-f fwmark]] [-r rsipaddr rsport]
-v vsipaddr vsport : ip address & port of the virtual server
-f fwmark : the fwmark number
-r rsipaddr rsport : ip address & port of the real server
Belong to -v or -f VS
Samples:
TCP|UDP VS: lvsgsp -v 192.168.200.10 80
TCP|UDP VS with RS: lvsgsp -v 192.168.200.10 80 -r 192.168.100.1 80
FWMARK VS: lvsgsp -f 1
=> -r to grab value of a specific realserver.
>thanks Alexandre! I am currently using 0.2 (?) release that you
originally
>posted on the web...
New release still compatible with all your configuration.
>PS - MRTG question - do you use something on the 'year' graph to make
things
>look nicer? check out these examples... looks great till year, then it
>looks like strange..
... I recommand using rrdtool since you can configure it much more finely
than MRTG. If you need help on it let me know, will help you :)
Best regards,
Alexandre
