Network monitoring conventionally consists of observing a network’s bandwidth usage in order to determine areas of congestion or to analyze equipment or software problems. Nagios and MRTG are useful, Open Source monitoring utilities that run with Linux and can be used to understand mixed-platform environments where UNIX and MS Windows coexist. Progent's network integration experts can help you deploy both these utilities to optimize and troubleshoot your infrastructure.
Nagios Network Monitoring Application
The Nagios Open Source monitoring application is a host and service monitor that runs under Linux. The Nagios daemon executes intermittent checks on hosts and services you specify by means of outside plug-ins which bring back status information to Nagios. When issues are detected, the Nagios can send notifications to administrative personnel in a variety of ways such as email, instant messaging, or SMS. Current status information, archival records, and analysis reports can be accessed using a standard web browser.
Major capabilities of the Nagios monitor are:
- Monitoring of system services such as SMTP, HTTP, SSH, and PING
- Monitoring of host resources: processor load, memory/disk usage, running processes, etc.
- Ability to define host hierarchy, allowing differentiation between hosts that are not running as opposed to ones that are not accessible
- Support personnel alerts by email, beeper, or other pre-specified method in case service or machine problems occur or are fixed
- Ability to specify scripts to be executed upon the detection of service or host events for automated problem resolution
- Support for deploying backup and distributed monitoring computers
- Outboard command option that enables on-the-fly modifications to be made to the tracking and notification behavior via the utilization of event scripts, the web GUI, and third-party software
- Retention of host and service state across program restarts
- Planned downtime for suppressing machine and service notifications when there are intentional service breaks
- Web interface for examining existing network status, notification and anomaly history, event logs, etc.
- Authorization protocol that allows you to limit what customers can see and modify from the browser interface
MRTG is a free tool to track the traffic load on a network. Running under Microsoft Windows or Linux, MRTG reads the traffic counters of network routers and creates web-accessible graphs which offer a live visual representation of this data.
Multi Router Traffic Grapher lets you track the bandwidth in and out of any SNMP-enabled network appliance. This can represent servers, routers, and switches. Administrators can utilize the displayed data to determine system bottlenecks.
Data you can depict with MRTG include:
- Throughput in bits or bytes per second
- Connection rate in connections per second
- Bandwidth in an out of a particular VIP server or real server
- Total number of simultaneous sessions
