Setup collectd

Add these lines to /etc/collectd/collectd.conf:

TypesDB "/usr/share/collectd/types.db" "/PLUGIN_PATH/types.db"
LoadPlugin exec
<Plugin rrdtool>
  DataDir "/var/lib/collectd/rrd"
</Plugin>
<Plugin exec>
  Exec nobody "/PLUGIN_PATH/zservertracelog.py" "/path/to/trace.log" "instance_name"
</Plugin>

Replace PLUGIN_PATH to path of this repository on server.

Also you can change nobody to user, that can access trace.log file.

Restart collectd:

sudo service collectd restart

Setup collection.cgi

Add this code snippet to collection.cgi, in $GraphDefs hash:

zoperequest => [
    '-v',
    's',
    'DEF:reqavg={file}:reqavg:AVERAGE',
    'DEF:reqmin={file}:reqmin:MIN',
    'DEF:reqmax={file}:reqmax:MAX',
    'DEF:appavg={file}:appavg:AVERAGE',
    'DEF:appmin={file}:appmin:MIN',
    'DEF:appmax={file}:appmax:MAX',
    "AREA:reqmax#$HalfBlue",
    "AREA:reqmin#$Canvas",
    "AREA:appmax#$HalfRed",
    "AREA:appmin#$Canvas",
    "LINE1:reqavg#$FullBlue:Total     ",
    'GPRINT:reqmin:MIN:%5.1lf%s Min,',
    'GPRINT:reqavg:AVERAGE:%5.1lf%s Avg,',
    'GPRINT:reqmax:MAX:%5.1lf%s Max\l',
    "LINE1:appavg#$FullRed:Processing",
    'GPRINT:appmin:MIN:%5.1lf%s Min,',
    'GPRINT:appavg:AVERAGE:%5.1lf%s Avg,',
    'GPRINT:appmax:MAX:%5.1lf%s Max\l',
],

collection.cgi file can be found in /usr/share/doc/collectd-core/examples/collection.cgi.
