Sensorsoft SSA7708 Templates for Cacti

Description:

This is a perl script (which requires net snmp) and a pair of xml templates to monitor the temperature and humidity readings from the Sensorsoft SSA7708 (and probably other members of that family with modifications) environmental sensor.

Platform:

  • Cacti
  • Unix (at least... net snmp is required)
  • Language:

  • XML
  • Perl
  • Screenshots:



    Code:

    #!/usr/bin/perl
    
    # This is a script for reading the SNMP data from a Sensorsoft SSA7008 environmental
    # monitoring device.  In this case it is pulling the temperature and humidity data
    # from a sensor plugged into the first port.
    
    # Output from this script is in a format that Cacti can be made to understand.
    
    # Cacti has difficulty polling this device directly, because in order to get either
    # of these values you first have to set a second value that will indicate which
    # value to poll.
    
    # If your sensorsoft is configured somewhat differently you will have to adjust
    # this script to suit your needs.
    
    # This script lives at http://www.elifulkerson.com
    
    # Requirements:
    # - perl
    # - snmpget (from NET SNMP)
    # - snmpset (from NET SNMP)
    
    
    $sensor_ip_address = "YOUR IP ADDRESS HERE";
    $snmp_community = "YOUR SNMP COMMUNITY HERE";
    
    #temperature
    $tmp = `snmpset -v1 -c $snmp_community $sensor_ip_address .1.3.6.1.4.1.15848.1.16.0 i 4`;
    $tmp = `snmpget -v1 -c $snmp_community $sensor_ip_address .1.3.6.1.4.1.15848.1.20.0`;
    
    $tmp =~ s/SNMPv2-SMI::enterprises.15848.1.20.0 = STRING: \"//;
    $tmp =~ s/ F\"//;
    $tmp =~ s/ \% RH\"//;
    
    # humidity
    $tmp2 = `snmpset -v1 -c $snmp_community $sensor_ip_address .1.3.6.1.4.1.15848.1.16.0 i 2`
    ;
    $tmp2 = `snmpget -v1 -c $snmp_community $sensor_ip_address .1.3.6.1.4.1.15848.1.20.0`;
    
    $tmp2 =~ s/SNMPv2-SMI::enterprises.15848.1.20.0 = STRING: \"//;
    $tmp2 =~ s/ F\"//;
    $tmp2 =~ s/ \% RH\"//;
    
    chomp($tmp,$tmp2);
    
    print "temp:$tmp humidity:$tmp2\n";
