The ENVIROMUX-MINI-LXO Graphs the Data from its Sensors Using MRTG

The ENVIROMUX-MINI-LXO Server Environment Monitoring System can graph the data from its sensors using MRTG (Multi Router Traffic Grapher). This 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

'Daily' Graph (5 Minute Average)
Server Room Humidity - Daily Graph
Max   Average   Current
76.7 °F   75.2 °F   70.8 °F

'Weekly Graph' (30 Minute Average)
Server Room Humidity - Weekly Graph
Max   Average   Current
78.3 °F   72.4 °F   70.3 °F


Configure MRTG to graph environmental conditions using the ENVIROMUX-MINI-LXO Server Environment Monitoring System:

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

2) Configure the ENVIROMUX-MINI-LXO 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:

4) Test run MRTG manually to ensure it is working properly.
  • The first few times MRTG is run with a newly created env-mini config, it will show non critical errors and does not cause any long term issues. This will only happen once for each sensor. After each sensor is tried once, these messages will go away and MRTG will operate as expected.

5) Create a cron job to run MRTG on UNIX machines. Use a daemon on Windows.

6) Modify MRTG graphs.
