No problems, ask away... >(1) Do I need to install SNMP to use MRTG ? is it a MUST ? I want to use MRTG >to monitor network >traffic and cpu load in particularly. It all depends. If you want to query all the boxes in the same manner (via snmp) - probably. If all you want to do is trend the cpu on the box where MRTG is installed - you can, but you can also do so through external programs. For my MRTG box, I have an external script inspired by Alex van den Bogaerdt's FAQ that gives me very detailed information on the CPU activity, which is not normally available via SNMP. For all my Netware and Windows boxes, I use SNMP to query them remotely. >(2) What is the difference between MRTG and RDDTOOL ? Can I use MRTG without >RDDTOOL ? If >yes, >what is the consequencies ? MRTG is a completely self-contained program (pretty much) that collects the data, stores the data, draws the graphs and generates the html pages housing those graphs. RRDtool is more of a database, with external plug-ins to collect the data, draw graphs and generate html. These are basic differences, and I'm sure there are opinions about what I just said. MRTG does everything you need automatically using it's own process. RRDtool needs something (like MRTG) to collect the data, something to insert the data (again, like MRTG), something to draw the graphs (like 14all or mrtg-rrd) and something to write out the html (again, 14all or mrtg-rrd). There are other tools (like Cricket, routers, et al.) listed on the RRDWorld link that can do the same thing as MRTG. But they all need RRDtool to store the data. Yes, SNMP is a protocol, but it is also commonly referred to as the application daemon running on the host (or client) machine. HTH!
