Network Monitoring
Monitoring Network Services
How to monitor various services across the network using SNMP:
- BIND 9
- Monitor the number of successful and failed queries.
- Cacti
- Scripts and information related to Cacti.
- Postfix
- Monitor the number of emails sent and recieved.
- OpenBSD's Packet Filter

Tools
Some of the tools used to monitor network hosts:
- MRTG
- Multi Router Traffic Grapher: Polls hosts via SNMP and creates graphs based on the data. Can be used together with RRDtool.
- Cacti
- Cacti is the slickest and one of the easiest to use network monitoring tools around. All setup and configuration is done via the web interface. Everything from the way it queries hosts to the style and layout of the graphs is customizable.
- RRDtool
- Round Robin Database -- stores data and generates graphs. Many other projects use RRDtool as part of their foundation, including MRTG and Cacti.
- mrtg-rrd.cgi
- A CGI/FastCGI script used to generate graphs of the data that MRTG stores in an RRD database.
- Net-SNMP
- Formerly ucd-snmp, this software package contains various tools relating to SNMP: an SNMP agent, trap daemon, client applications, and more.
- InstantView
- Provides a graphical, map-based monitoring point of network nodes and links. Uses data collected from SNMP, ICMP, syslog, and more, to present an up to the minute view of network status.
