1. Remstats An RRDtool-based Network Monitoring System by Thomas Erskine

2. Why another network monitoring system? The existing ones were either: –inadequate, and/or –extremely expensive, and/or –not customizable enough

3. 1999-09-21Remstats - NANOG3 What did you want? graphs and long-term data-storage like MRTG and RRDtoolRRDtool alerts and status-levels like NOCOLNOCOL data from non-SNMP sources

4. What’s 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. 1999-09-21Remstats - NANOG6 Decoupling the collector use other data-sources, anything you’ve 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? I’m glad you asked. Let’s have a look…

18. 1999-09-21Remstats - NANOG18 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)
