Network monitoring typically entails tracking a system's data traffic to help determine bottlenecks or to troubleshoot hardware or software issues. Nagios and MRTG are powerful, no-cost monitoring tools that run with Linux and can be used to understand multi-platform environments where UNIX family systems and MS Windows both operate. Progent's network support consultants can show you how to deploy each of these utilities to tune and repair your network.
Nagios Open Source Monitoring Application
The Nagios Open Source monitoring system is a host/service monitor that operates under Linux. The Nagios daemon runs periodic inspections of servers and services you request by means of external add-ons which bring back status data to Nagios. When issues are detected, the Nagios can send notifications to administrative contacts in a variety of ways such as email, instant messaging, or Short Message Service. Current status information, archival records, and analysis reports can be accessed using a web browser.
Key features of Nagios are:
- Monitoring of system services such as SMTP, HTTP, FTP, and PING
- Tracking of host resources: CPU load, memory/disk usage, log files, etc.
- Capability to specify host hierarchy, allowing differentiation between machines that are down as opposed to hosts that are unreachable
- Support personnel alerts via email, beeper, or other user-defined means in case service or host problems occur or get resolved
- Option to define event handlers to be run during service or host events for proactive problem resolution
- Support for deploying backup and distributed monitoring servers
- External command option that allows ad hoc modifications to be defined for the tracking and notification behavior via the use of event scripts, the web interface, and third-party applications
- Retention of host and service status across program restarts
- Scheduled offline periods for suppressing machine and service alerts when there are deliberate service breaks
- Web interface for viewing existing system state, notification and problem history, event logs, etc.
- Authorization protocol that allows you to restrict what users can see and modify from the browser applet
Multi Router Traffic Grapher (MRTG)
MRTG Graphical Traffic Load Monitor is an Open Source tool to track the traffic load on your network. Running under Windows or Linux and most UNIX platforms, MRTG reads the traffic counters of routers and generates web pages which provide a live visual representation of this data.
Multi Router Traffic Grapher lets you track the traffic through any SNMP-enabled network appliance. This can represent servers, routers, and switches. You can utilize the resulting information to identify network bottlenecks.
Data you can depict using MRTG include:
- Throughput in bits or bytes per second
- Connection rate in connections/sec
- Throughput through a particular Virtual server or node server
- Number of concurrent sessions
