Hi, If anyone can help with this, I very much appreciate it. I have used MRTG a lot for traffic monitoring, server monitoring and weather station monitoring, but always (till now) using the default 5 minute interval. What I am trying to now is monitor our many (ie 125) printers on an hourly basis, but am getting some unexpected results, and can't see what is wrong. Apologies in advance for the long email, but I think it is best to give as much info. as I can up front. ############################################################# Here is what I am doing:- === We print via Novell's NDPS, and I can extract each printer's job count from the NDPS/Netware host servers. (BTW, I tried getting page counts from our collection of Intel Netports and HP Jetdirects, but the results were to variable - most don't update their SNMP counters). === I have a shell script running from CRON on the hour. 0 * * * * ~/getndps >> getndps.log 2>&1 It gathers the data and splits it into many text files, 2 per printer. As an example, for printer "ku13" it creates data/ku13.data (which is where MRTG gets its data) and data/ku13.hist (handy for debugging, and maybe some custom tabular web pages later on). It then calls MRTG to digest the data. ====== here is ku13.data (1 line with the cumulative job count. The count is low because we had to restart the NDPS server yesterday) ku13 95 ====== and here is ku13.hist Tue May 27 11:00:03 EST 2003 ku13 41 Tue May 27 12:00:02 EST 2003 ku13 46 Tue May 27 13:00:04 EST 2003 ku13 54 Tue May 27 14:00:02 EST 2003 ku13 66 Tue May 27 15:00:05 EST 2003 ku13 76 Tue May 27 16:00:08 EST 2003 ku13 95 Here is a snip from my jobs.cfg file for MRTG (the header, plus the ku13 portion) HtmlDir: /home/ndps/html/ ImageDir: /home/ndps/images/ Logdir: /home/ndps/logs/ Options[_]: growright, perhour, nopercent, integer, noinfo, withzeroes, noo Refresh: 3600 Interval: 60 WriteExpires: Yes # Target[ku13]: `awk ' /ku13/ { print $2; print 0; print 0; print 0 }' data/ku13.d ata ` Title[ku13]: Print Jobs on printer ku13 PageTop[ku13]:
