I'm using perhour option to graph some usage stats (number of pages printed on HP printer). It doesn't make sense to count how many pages are printed each second, but it does make sense to track it by hour. So I attempted to use "perhour" option. However, after printing couple of pages on the printer, the graphs have strange peaks, showing something like couple of hundred pages printed per hour (which is wrong). The data is polled from the printer every 5 minutes (with some other data, like network traffic, memory usage and toner levels). My wild guess is that the problem is I'm polling the data way too often, and MRTG isn't smart enough to handle this properly.
To solve the problem, I was thinking about creating separate cronjob that runs only once an hour to poll only this data from the printer. If I'm right that the problem is simply polling the data too often, it should solve it. However, than I'd need to wait for one hour for graphs to update (and I'd like more realtime response if possible). The entry in config file I currently have looks something like this: Target[hp.pages]: .1.3.6.1.2.1.43.10.2.1.4.1.1&.1.3.6.1.2.1.43.10.2.1.4.1.1:[EMAIL PROTECTED] Options[hp.pages]: nopercent,noinfo,growright,perhour Step[hp.pages]: 3600 Title[hp.pages]: Pages Printed PageTop[hp.pages]: <h1>Pages Printed -- HP LaserJet</h1> MaxBytes[hp.pages]: 1000000 YLegend[hp.pages]: # Pages per Hour ShortLegend[hp.pages]: LegendI[hp.pages]: Pages: LegendO[hp.pages]: Legend1[hp.pages]: Pages Printed Is there some better way to plot this kind of data? -- See Ya' later, alligator! http://www.8-P.ca/ -- Unsubscribe mailto:[EMAIL PROTECTED] Archive http://lists.ee.ethz.ch/mrtg FAQ http://faq.mrtg.org Homepage http://www.mrtg.org WebAdmin http://lists.ee.ethz.ch/lsg2.cgi
