and no. You need to use <b>Include:</b> to link them all into a master.cfg
and then run MRTG with this, which means they must share all the same global
declarations. I’m working on a patch for MRTG to allow wildcards in
the Include: directive but at the moment each file needs to be declared
individually. The recommended ‘best practice’ is to have one
cfg file per device, then optionally link them all together with a ‘master.cfg’
file that uses Include: statements. You can also have a ‘global.cfg’
file that is included by the various device cfg files, which can contain the
various global declarations like LogFormat, Interval, WorkDir, and so on. This
forum post talks about it: http://www.steveshipway.org/forum/viewtopic.php?f=2&t=4093<o:p></o:p></span></p>

you are running as a daemon, then you can use ‘Forks:’ (if you are
running under linux/unix) to control the number of threads used, and tune this
to make sure the checks are spread out over the 5min interval. Here, we
have home-grown code that makes certain of an even spread in scheduling.
The hit on the network is not really significant; it’s the hit on the
MRTG system CPU and memory that is more a problem. You can use RRDTool
1.4.x with rrdcached (in unix socket mode) to improve disk speed, but you
need to use the development snapshot of MRTG for this to work.<o:p></o:p></span></p>

you have ‘Logformat: rrdtool’ in the MRTG cfg file, then it will

specify the location of the RRDTool Perl libraries if you have not installed
them into the site-perl path. Note that, if in RRDTool mode, you will
need to have a frontend installed (eg, routers2 or 14all) as MRTG will no
longer generate the graph images every cycle.<o:p></o:p></span></p>
