panagenda GreenLight uses various methods to request system data from different monitoring targets. All data is collected by so-called sensors. Sensors are software modules running on the panagenda GreenLight virtual appliance that request information from a given monitoring target at given scheduled rate. In the Sensor section of this Administrator's Guide, you will find more detailed information about sensors.
 
A typical sensor request has four steps:
 

Sensor measurement steps
 
     Request data from target system
     Receive data from target system
     Transform data for better readability and optimize it for storage
     Store transformed data into panagenda GreenLight's internal data warehouse
 
Step 3 is often used on complex sensor result set, but not mandatory.
Step 4 is optional and can be configured while sensor setup (but it is set per default). More information about sensor results can be found in General Information for all Sensors.
