Network monitoring typically entails tracking a system's data traffic to help identify choke points or to troubleshoot hardware or application issues. Nagios and MRTG are powerful, no-cost monitoring tools that operate with Linux and can be used to monitor mixed-platform networks where UNIX family systems and Windows both operate. Progent's system integration engineers can help you deploy each of these utilities to optimize and repair your infrastructure.

Nagios Open Source Monitoring Application
Nagios screenThe Nagios Open Source monitoring application is a host/service monitor that runs with Linux. The Nagios daemon executes intermittent inspections of servers and services you request by means of outside add-ons which bring back status information to Nagios. When issues are detected, the Nagios can send notifications to support personnel in a variety of ways such as email, instant messaging, or Short Message Service. Up to date status data, archival records, and reports can be accessed via a web browser.

Key features of Nagios include:

  • Tracking of system services such as SMTP, HTTP, SSH, and PING
  • Tracking of host machines: CPU load, disk and memory usage, log files, etc.
  • Capability to define network host ranking, allowing distinction between hosts that are down as opposed to ones that are not accessible
  • Contact notifications by e-mail, beeper, or other pre-specified method in case service or host problems are detected or get fixed
  • Ability to define scripts to be executed upon the detection of service or machine events for proactive problem resolution
  • Accommodation for implementing backup and distributed monitoring servers
  • External command interface that enables ad hoc edits to be defined for the tracking and notification activity through the use of event handlers, the web interface, and third-party software
  • Preservation of host and service state across program restarts
  • Scheduled downtime for suppressing host and service alerts during deliberate outages
  • Browser interface for viewing current system state, notification and problem history, event logs, etc.
  • Permissions protocol that permits you to limit what users can view and do from the web applet

MRTG consulting servicesMulti Router Traffic Grapher (MRTG) is an Open Source tool to track the traffic load on a network. Powered by MS Windows or Linux and most UNIX platforms, MRTG captures data from the traffic counters of network routers and produces web-accessible graphs which offer a live visual representation of this traffic.

Multi Router Traffic Grapher allows you to graph the bandwidth in and out of any SNMP network device. This can represent servers, routers, and switches. You can use the resulting information to determine network trouble spots.

Type of information you are able to depict using MRTG include:

  • Throughput in bits or bytes per second
  • Connection rate in connections/sec
  • Throughput through a specific VIP server or node server
  • Number of simultaneous sessions
