graphing large values (k/M/T/etc) with 14all.cgi

graphing large values (k/M/T/etc) with 14all.cgi

Post by Brendon Caligar » Wed, 23 Apr 2003 00:32:10



Environment:
    RH7.3 + stock net-snmp (latest rh patch releases)
     mrtg-2.9.29.tar.gz
    14all-1.1p25.tar.gz
     rrdtool-1.0.41.tar.gz

mrtg is running in 'rrdtool' mode

Appended to this message is the mrtg.cfg extract which I am using to graph
the available space versus size of my '/' partition.

The snmp gets are retrieving the right information (disk size / availability
in megabytes).

The values of the preview screen are ok (the right number of Gbs) whilst the
5min/weekly/monthly/yearly graphs  give the X-axis in megabytes.  I would
like to 'coerce' 14all.cgi into displaying 'G' instead of 'k' and 'M'
instead of nothing as I trying to graph megabytes not bytes (I am already
extracting the values in megabytes).

I have tried toying with the kMG[target] variable but it seems to be ignored
completely!!!

Any help welcome!!!!

1. Changing graph size and scale in 14all.cgi

I would like to make the graphs displayed by 14all.cgi larger.

I would also like to change the 5 minute graph so that the x axis
covers about an 8 hour time period. My goal is to see more detail.

Is this possible? I am not a programmer, so detailed instructions
would be much appreciated. I intend on writing a MRTG RRDTool 14all
web page for people trying to run this combination on Win2000 Pro --
something that will be easy for "router guys" to follow.

Thanks in advance
