Chris, One very important piece of information you leave out is how fine a resolution you want. MRTG doesn't do 24 hours for anything. 33 hours, 20 minutes is the closest. That is a 5 minute resolution. Then there's a 30 minute resolution for 400 30 minute periods, a 2 hour resolution for 400 2 hour periods, and a 1 day resolution for 400 days. See the theme? You say you want 2 years worth of data, but at what resolution? 30 seconds, 5 minutes, a half hour, 2 hours, 1 day, 1 month? It also depends on how often (at a minimum) you plan to update each RRA.
Funny you say graphing leaves something to be desired. Graphing capabilities are usually what draw people to the whole MRTG/RRDTool world in the first place. Have you checked out the MRTG FAQ (http://faq.mrtg.org)? If you want to add something to it or think you have an idea how to make it better, I'm sure the powers that be are always willing to listen... Paul >>> "Chris Knipe" <[EMAIL PROTECTED]> 08/10/02 13:53 PM >>> Lo all, Not wanting to sound like a pathetic lazy newbie here (Newbie to RRD I am though, lazy I don't think), I've read through the various documentation that comes with RRDTool over 25 times now (As well as a mini-howto I found via google). Either I am just really stupid, and unfortunately maths never was my strong point - which is making my quest harder I think. I was wondering if anyone perhaps know of some really good docs explaining how RRD works. I think I've managed to get the creation of the databases under my belt, but the graphing, leaves ALLOT to be desired. I am totally clueless as to how to create the graphs I want, and are semi-clueless on the creationof databases. To give you guys a example of what I want to achieve right now (perhaps one of you would be so kind to provide me with the code to create the db and do the graphing - though, I'd still like to RTFM on my own)... I want to monitor Cisco serial ports, and capture incoming and outgoing traffic, 2yrs worth of archives. Now that's fairly easy, I think I've managed to get a DB for this. Now, I want to create 4 graphs out of this information. 1) Incoming / Outgoing Traffic in the last 24hrs (MRTG Equivalent) 2) Incoming / Outgoing Traffic in the last month (MRTG Equivalent) 3) Incoming / Outgoing Traffic in the least year (MRTG Equivalent) 4) Total traffic used in the *current* Month. With a additional line, indicating anything below a threshold (say, 1GB) in one colour, and everything above the threshold in a alternative colour. (Should be only from 01/01/01 to 31/01/01 for example, hence, the total traffic incoming over the interface, for the current month it is in). Additionally, I'd also like to know how I can export RRD's data to a CSV type file. I am *totally* clueless as to how I can achieve this... The docs are good however, I'm sure it's just me that's being rather stupid, and once I get the proper syntax, I'm more than likely going to kick myself for not thinking of it myself - but after battling with this for two months now, I need to find a solution rather quickly, seeing that my deadline to implement the system is slowly crawling nearer and nearer.
