Network monitoring conventionally consists of tracking a system's data traffic in order to identify bottlenecks or to troubleshoot equipment or application issues. Nagios and MRTG are powerful, Open Source monitoring tools that operate under Linux and can be helpful to monitor mixed-platform environments where UNIX family systems and MS Windows coexist. Progent's IT integration consultants can help you use each of these products to optimize and troubleshoot your network.
Nagios Open Source Monitoring System
The Nagios network monitoring application is a host and service monitor that runs under Linux. The Nagios daemon runs intermittent inspections of hosts and services you request using outside plug-ins which bring back status information to Nagios. When issues are detected, the daemon can send notifications to support personnel in a number of ways such as email, instant messaging, or SMS. Current status information, historical logs, and analysis reports can be examined via the web.
Key capabilities of the Nagios monitor are:
- Tracking of network services such as POP3, HTTP, FTP, and PING
- Monitoring of host resources: processor load, disk and memory usage, running processes, etc.
- Capability to define host hierarchy, allowing differentiation between machines that are not running vs. ones that are not accessible
- Support personnel notifications by email, pager, or other pre-defined means when service or machine issues occur or get fixed
- Ability to specify scripts to be run during service or machine events for automated problem resolution
- Accommodation for implementing backup and distributed network monitoring computers
- External command option that allows ad hoc edits to be defined for the tracking and notification behavior through the use of event handlers, the web interface, and third-party applications
- Preservation of machine and service state across application restarts
- Planned downtime for eliminating machine and service notifications during deliberate service breaks
- Web interface for viewing current network state, notification and anomaly history, log file, etc.
- Permissions scheme that enables you to restrict what users can view and do via the browser interface
MRTG Graphical Traffic Load Monitor
Multi Router Traffic Grapher (MRTG) is an Open Source tool to track the bandwidth utilization on a network. Powered by Microsoft Windows or Linux and most UNIX platforms, MRTG captures data from the traffic counters of network routers and creates web pages which provide an up-to-date intuitive representation of this data.
Multi Router Traffic Grapher permits you to graph the traffic in and out of any SNMP network device. This includes processors, routers, and switches. You can utilize the resulting data to determine system trouble spots.
Data you can graph with MRTG include:
- Traffic in bits or bytes/sec
- Connection rate in connections/sec
- Bandwidth in an out of a particular Virtual server or real server
- Total number of simultaneous sessions
