Monitorix – lightweight system monitoring tool

Monitorix is a free, lightweight, open source system monitoring tool designed to monitor as many services as possible.

This application monitors CPU load and temperatures to the users on the system. Network devices activity, network services demand and even the devices’ interrupt activity are also monitored. The current status of any corporate server with Monitorix installed can be accessed via a web browser.

It has been designed to be used under production Linux servers, but due its simplicity and small size you can use it to monitor embedded devices.

Features include:

  • Monitors:
    • System core (CPU load and temperatures, active processes and memory allocation).
    • Global or per-processor/core kernel usage (user, nice, system, idle and I/O wait).
    • Temperatures (HP ProLiant IML Agent and LM-Sensors with HDDtemp support).
    • Mounted filesystems and disk I/O.
    • Activity of up to 5 network devices.
    • Use of SMTP, SSH, FTP, Telnet, Samba, NetAtalk, VirusMail, FAX, POP3 and HTTP services.
    • Complete MTA statistics including anti-spam, anti-virus and greylisting.
    • Activity of up to 12 predefined network ports.
    • Devices interrupt activity (APIC support with up to 256 different interrupts).
    • and more.
  • Support for HP Insight Management Agents for ProLiant servers.
  • Support for Samba v2 and v3, Sendmail, Postfix, NetAtalk, Qpopper and Hylafax status logs.
  • Support for the Nginx web server statistics.
  • Support for remote servers monitorization (Multihost feature).
  • Silent mode to be able to retrieve the graphs from scripts or other programs.
  • Traffic statistics are stored on disk into RRD format fixed-size databases.
  • Possibility to view statistics per day, week, month or year.
  • Possibility to view statistics with rendered graphs or in plain text.
  • Each picture can be zoomed in to see the graph in more detail.
  • Monthly traffic activity report via email can be sent to LAN users.
  • Warns if some selected network port is not listening.
  • Two alert capabilities cover either if CPU load average or the root filesystem reaches or exceeds a threshold value for an specified amount of time.
  • Web interface offers minimal learning, ubiquitous access.
