Hi folks!
Just want to say we've been using mrtg and rrdtool for quite some
times here to monitor many bandwidth links ... it's fantastic. I have a
need to change some MaxBytes entries quite often, which means in the cfg
files, I'm changing the MaxBytes line and then the description down
below, in the html table (the <TR><TD>Max Speed:</TD> <TD>128
kbits/s</TD></TR> line)... I wanted to automate this process, perhaps
write a script, (we already have a php/mysql front end, if we modify
someone's bandwidth, I want the change to propagate back to the config
file.) So my question is this: any way to make the description table
interpolate variables (such as ones set by the SetEnv keyword) or does
the mrtg script take all html tags literally? My idea is to write a
script that selects out the MaxBytes[] line of a specific target,
replace it with the new value, and if there is a corresponding
description in the table, make it dependent on the value of the MaxBytes
line. (Tried a few things such as setting SetEnv[target]:
MaxBytes="16000" then having it interpolate in the <table>, but to no
avail...) Any help would be greatly appreciated! Thanks!
