Setting Custom Check Conditions

The Auto-Response facility (in all console servers with Firmware V3.5.1 and later) uses Check Conditions to trigger action sequences. Included is a Custom Check which allows uses to run a nominated custom script executable (with nominated arguments) whose return value is used as the trigger event. The script executable can be used to monitor nominated ports/ device status, or to probe the state of software applications or services running on other computers and appliance at the site:

• Click on Custom Check as the Check Condition
• Create an executable trigger check script file (e.g. the file below named /etc/config/test.sh )

#!/bin/sh 
logger "A test script" 
logger Argument1 = $1 
logger Argument2 = $2 
logger Argument3 = $3 
logger Argument4 = $4 
if [ -f /etc/config/customscript.0 ]; then 
rm /etc/config/customscript.0 
exit 7 
fi 
touch /etc/config/customscript.0 
exit 1

• Enter the Script Executable file name (i.e. /etc/config/test.sh). For other examples of custom script executables referfaq417-More-Custom-Script-Checks
  
   
  
  
• Set the Check Frequency (i.e. the time in seconds between re-running the script) and the Script Timeout (i.e. the maximum run-time for the script) 
• Specify the Successful Return Code. An Auto-Response is triggered if the return code from the script is not this value
• Enter Arguments that are to be passed to the script (e.g. with a web page html check script, these Arguments might specify the web page address/DNS and user logins)
• Check Save Auto-Response
