ENVIROMUX® Enterprise Environment Monitoring Systems Graph Critical Environment Conditions with MRTG



The ENVIROMUX-2D, ENVIROMUX-5D and ENVIROMUX-16D Monitoring environmental conditions around servers, work stations or data centers helps prevent the damages caused to valuable equipment by environmental conditions like temperature, humidity, water leakage etc.

The Network Technologies Inc ENVIROMUX® Enterprise Environment Monitoring Systems monitors critical environmental conditions, such as temperature, humidity, liquid water presence, power, intrusion, and smoke. When a sensor goes out of range of a configurable threshold, the system will notify you via email, LEDs, alarm beacon, siren, web page, network management (SNMP), voice phone calls (via Automatic Voice Dialer System), and SMS messages (via external USB 3G modem).

Graphing using MRTG (Multi Router Traffic Grapher) provides a visual representation of the critical environmental conditions being monitored. MRTG generates HTML pages containing regularly updated PNG images providing graphical trending of time-series data. The graphs display daily, weekly, monthly and yearly statistics of the environmental conditions being monitored.

Sample Graphs

Internal Temperature: Daily Graph (5 Minute Average)
Max   Average   Current
73.7 °F   71.1 °F   73.7 °F

Internal Temperature: Weekly Graph (30 Minute Average)
Max   Average   Current
73.5 °F   71.6 °F   73.4 °F


Configure MRTG to graph environmental conditions using the ENVIROMUX Enterprise Environment Monitoring System:

1) Install MRTG on your computer using the MRTG installation guide.

2) Configure the ENVIROMUX server environment monitoring system to monitor the environmental conditions you want.

3) Create a MRTG configuration file that controls the graphs.

  • Note: You can also edit the summary HTML file below to display data from the sensors you use.
    • Simply replace ENVIROMUX-xD in the title and table tag to the ENVIROMUX unit you are using.

4) Test run MRTG manually to ensure it is working properly.
5) Create a cron job to run MRTG on UNIX machines. Use a daemon on Windows.

6) Modify MRTG graphs.
