[SLUG] MRTG Demo data source
Dear list, I need to do a demo of signal graphing, so I though I would use MRTG. As I am away from my office, so I thought I would use two laptops. One of the server and the other as a client. The point is to show that we can do remote monitoring of 'real time' data. Yes, I admit the demo is dodgy and pointless but these people wanted to see a box with graphs draw in 'real time' (and blinking lights) What non-SNMP / MIB2 data sources are available? regards, Richard Hayes -- Richard Hayes Nada Marketing PO Box 12 Gordon Australia 2072 Tel: +(61-2) 9412 4367 Fax: +(61-2) 9412 4920 Mob: +(61) 0414 618 425 www.nada.com.au -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

It's very easy to plug an arbitrary non SNMP data source into MRTG. The output just needs to be in the format Line 1 current state of the first variable, normally 'incoming bytes count' Line 2 current state of the second variable, normally 'outgoing bytes count' Line 3 string (in any human readable format), telling the uptime of the target. Line 4 string, telling the name of the target. As an example, openupsmart (openupsmart.sf.net) when running will give status output on a port like this : [EMAIL PROTECTED]:~$ /usr/pkg/sbin/nc localhost 8740 248.0 58.0 28 days, 21 hours, 46 minutes, 35 seconds OpenUPSmart This can be snarfed into MRTG with a target like Target[ups]: `/usr/pkg/sbin/nc localhost 8740` MaxBytes[ups]: 300 Title[ups]: UPS Statistics PageTop[ups]: H1UPS Statistics/H1 YLegend[ups]: Power Statistics ShortLegend[ups] : nbsp; LegendI[ups]: nbsp;Volts LegendO[ups]: nbsp;Load options[ups]: gauge, nopercent You could use openupsmart if you wanted; there is a UPS simulator included in the source which you could quite easily modify to return some sort of reasonable random variables to make it look real. (http://openupsmart.sourceforge.net/mrtg/ups.html is a sample of actual data) Probably easier to just write your own dummy device, though. -i signature.asc Description: Digital signature -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Then you could start Firefox and watch the amount of resident set memory increase, the network traffic increase, the CPU usage increase, etc. If your PC runs SMART and sensors you can also plot longer term stuff such as the disk and CPU getting hotter. -- Glen Turner Tel: (08) 8303 3936 or +61 8 8303 3936 Australia's Academic Research Network www.aarnet.edu.au -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
