Why another network monitoring system?
• The existing ones were either:– inadequate, and/or– extremely expensive, and/or– not customizable enough
1999-09-21 Remstats - NANOG 3
What did you want?
• graphs and long-term data-storage like MRTG and RRDtool
• alerts and status-levels like NOCOL• data from non-SNMP sources
What’s so great about it?
• RRDtool (thank-you Tobi)• good customizable graphs• long-term data retention in small
space• fast updates
Seriously.
• non-SNMP data collection• “At a glance” web-pages for each
host• custom web-pages with live data• custom images with live data• long-term event logs

Decoupling the collector
• use other data-sources, anything you’ve got
• write your own “collector”• how about a sed script?
OK. How does it work?
• Collectors feed a standard data format to the updater
• all the collectors run in parallel• afterwards monitors do data-
specific stuff • finally the web-pages get
generated
Enough! What does it look like?
• I’m glad you asked. Let’s have a look…

How do I make it do all that?
• A single configuration file• Sections for graphtimes, colors, archives,
tools, scripts, alerts, oids, rrds and hosts• configuration base supplied• configuration-creation tools for some collectors
(ping, snmp and port)
