Network monitoring conventionally entails observing a system's bandwidth usage in order to determine bottlenecks or to troubleshoot hardware or software problems. Nagios and MRTG are useful, free monitoring utilities that operate with Linux and can be used to understand mixed-vendor environments where UNIX family systems and Windows coexist. Progent's system support consultants can help you use both these utilities to tune and troubleshoot your infrastructure.
Nagios Open Source Monitoring System
The Nagios Open Source monitoring system is a host and service monitor that operates under Linux. The Nagios daemon executes intermittent checks on servers and services you request by means of outside add-ons which return status data to Nagios. When problems are detected, the daemon can generate alerts to management personnel in a number of ways such as e-mail, instant messaging, or Short Message Service. Up to date status data, historical records, and analysis reports can be accessed using a web browser.
Major capabilities of Nagios include:
MRTG
Multi Router Traffic Grapher (MRTG) is an Open Source utility to monitor the bandwidth utilization on your network. Running under Windows or Linux and most UNIX platforms, MRTG reads the traffic counters of routers and generates web-accessible graphs which provide a live intuitive depiction of this traffic.
Multi Router Traffic Grapher lets you track the traffic in and out of any SNMP-enabled network device. This includes processors, routers, and switches. You can utilize the resulting information to determine system trouble spots.
Data you can depict using MRTG include:
