1min MRTG - The 1 Minute MRTG Patches

1min MRTG

The 1 minute MRTG patches allow MRTG to work with 1 minute updates, instead of the hardcoded 5 minutes. Not only the updating system (cron in my case) has to run every minute, but a few things have to be modified here and there so; so that the generated graphs and webpage follow the 1 minute rythme.It's allready heavy enough to generate images every 5 minutes. For 1 minute updates, RRDtool is a must. These patchs apply to MRTG using RRDtool to store values. It hasn't been tested, and will probabily not work with rateup. It's fairly easy to run MRTG with RRDtool, check out the: MRTG and RRD tool document for a quick how-to, it's located on the MRTG website.
