Remstats

An RRDtool-based Network Monitoring System

by Thomas Erskine <thomas.erskine@crc.ca>

why another network monitoring system
Why another network monitoring system?
  • The existing ones were either:
    • inadequate, and/or
    • extremely expensive, and/or
    • not customizable enough
what did you want
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

Remstats - NANOG

what s so great about it
What’s so great about it?
  • RRDtool (thank-you Tobi)
  • good customizable graphs
  • long-term data retention in small space
  • fast updates
seriously
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
Decoupling the collector
  • use other data-sources, anything you’ve got
  • write your own “collector”
  • how about a sed script?

Remstats - NANOG

ok how does it work
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
Enough! What does it look like?
  • I’m glad you asked. Let’s have a look…
how do i make it do all that
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)
