Monitorix is a free, open source, lightweight system monitoring tool designed to monitorize as many services as possible. At this time it monitors from the CPU load and temperatures to the users using the system. Network devices activity, network services demand and even the devices’ interrupt activity are also monitored, and more. 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 UNIX/Linux servers, but due its simplicity and small size you can use it to monitor embedded devices.
All its development was initially created for monitoring Red Hat, Fedora and CentOS Linux systems, so this project was made keeping in mind these distributions. Today it runs on different Linux distributions and even in other UNIX systems like FreeBSD.
Monitorix is an open source project and, just like any other open source project, anyone can contribute with its own time and knowledgements.
- The monitorization includes:
- The system core (CPU load and temperatures, active processes and memory allocation).
- The kernel usage (user, nice, system, idle and i/o wait).
- The temperatures (HP ProLiant IML Agent and LM-Sensors with HDDtemp support).
- The mounted filesystems and disk i/o.
- The activity of up to 5 network devices.
- The use of SMTP, SSH, FTP, Telnet, Samba, NetAtalk, VirusMail, FAX, POP3 and HTTP services.
- The activity of up to 12 predefined network ports.
- The devices interrupt activity (APIC support with up to 256 interrupts).
- 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.
- 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.
- It warns if some selected network port is not listening.
- Web interface offers minimal learning, ubiquitous access.
- Configuration with only one text-plain file.
- Perl and Shell Script based (lightweight tool).
- Requires the RRDtool package and a CGI capable web server.
