I discover that mrtg is available as a package for CentOS-5. At first blush this seems the answer but would it in fact suffice for my purposes: measuring the total data volume passing over eth0 on the CentOS based host running mrtg? Is there a how-to guide to configuring snmp for eth0 on CentOS? I am afraid this this is all new territory for me and I am working under serious time and resource constraints. I have to get this done quickly and cheaply and I need a recipe to monitor total eth0 traffic cumulatively over a period of months. Getting the niceties of snmp mastered and in place must wait til a later date. Any pertinant advice is welcomed. -- *** E-Mail is NOT a SECURE channel *** James B.
