Remstats

• An RRDtool-based Network Monitoring System
• by Thomas Erskine ltthomas.erskine_at_crc.cagt

2
Why another network monitoring system?

• The existing ones were either
• inadequate, and/or
• extremely expensive, and/or
• not customizable enough

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

4
Whats so great about it?

• RRDtool (thank-you Tobi)
• good customizable graphs
• long-term data retention in small space
• fast updates

5
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

6
Decoupling the collector

• use other data-sources, anything youve got
• write your own collector
• how about a sed script?

7
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

8
Enough! What does it look like?

• Im glad you asked. Lets 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)
