Server Environment Monitoring MRTG Graph Temperature Humidity Data

Graph Critical Environmental Conditions

Enterprise Server Environment Monitoring System

The Server Environment Monitoring System monitors critical environmental conditions, such as temperature, humidity, liquid presence, motion, intrusion, and vibration. When a sensor goes out of range of a configurable threshold, the system will notify you via email, LEDs, alarm beacon, web page, network management (SNMP), and SMS messages (via external GSM modem).

NTI's ENVIROMUX Enterprise Server Environment Monitoring System Graphs Critical Environmental Conditions with MRTG

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® Server Environment Monitoring System monitors environmental conditions and notifies the administrator or staff via email, SNMP traps, web-page alerts etc. if a sensor goes out of range of a pre-configured limit.

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.

Server Environment Monitoring Graphs

Sample graphs:

Internal Temperature: Daily Graph (5 Minute Average)

	Max	Average	Current
Internal Temperature:	73.7°F	71.1°F	73.7°F

Internal Temperature: Weekly Graph (30 Minute Average)

	Max	Average	Current
Internal Temperature:	73.5°F	71.6°F	73.4°F

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

Install MRTG on your computer using the MRTG installation guide.
- Installation procedure is available at:
  - For UNIX: http://oss.oetiker.ch/mrtg/doc/mrtg-unix-guide.en.html
  - For Windows: http://oss.oetiker.ch/mrtg/doc/mrtg-nt-guide.en.html
  - For Netware: http://oss.oetiker.ch/mrtg/doc/mrtg-nw-guide.en.html
Configure the ENVIROMUX server environment monitoring system to monitor the environmental conditions you want.
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:
<html> <head> <title>Enviromux-SEMS-16</title> <meta http-equiv="refresh" content="300"> </head> <body> <center><table><tr><td align="center"> <h1>Sensors for ENVIROMUX-SEMS-16</h1> </td></tr></table></center> <table>  <tr><td> <a href="intsens_1.html">Internal Temperature<br> <img src="intsens_1-day.png" border="0" alt=""></a> </td></tr> <tr><td> <a href="intsens_2.html">Internal Humidity<br> <img src="intsens_2-day.png" border="0" alt=""></a> </td></tr> <tr><td> <a href="intsens_3.html">Battery<br> <img src="intsens_3-day.png" border="0" alt=""></a> </td></tr> <tr><td> <a href="extsens_1.html">Office Temperature<br> <img src="extsens_1-day.png" border="0" alt=""></a> </td></tr> <tr><td> <a href="extsens_2.html">Office Humidity<br> <img src="extsens_2-day.png" border="0" alt=""></a> </td></tr></table> </body> </html>
Test run MRTG manually to ensure it is working properly.
Create a cron job to run MRTG on UNIX machines. Use a daemon on Windows.
Modify MRTG graphs.
- The default graphs generated by the MRTG configuration script can be modified. Following are examples of changes to the graphs that can be made.
