Network monitoring conventionally consists of tracking a system's bandwidth usage in order to determine areas of congestion or to analyze hardware or software issues. Nagios and MRTG are useful, no-cost monitoring utilities that operate under Linux and can be used to understand mixed-vendor networks where UNIX family systems and Windows both operate. Progent's system integration consultants can show you how to use each of these products to tune and troubleshoot your network.
Nagios Network Monitoring System
The Nagios monitoring system is a host and service monitor that runs with Linux. The monitoring daemon runs intermittent inspections of servers and services you request by means of outside add-ons which bring back status information to Nagios. When problems are encountered, the daemon can generate notifications to administrative contacts in a variety of ways such as e-mail, instant messaging, or SMS. Current status data, archival records, and reports can be accessed via the web.
Major capabilities of the Nagios monitor include:
MRTG
MRTG is an Open Source tool to monitor the bandwidth utilization on a network. Running under MS Windows or Linux, MRTG reads the traffic counters of routers and creates web-accessible graphs which provide an up-to-date visual representation of this data.
MRTG lets you track the traffic in and out of any SNMP network appliance. This includes processors, routers, and switches. You can use the displayed information to identify network bottlenecks.
Type of information you can graph with MRTG include:
