Scripting and programming languages use variables to define important values that allow the NetMRI job engine to respond according to what it sees in the data it's parsing. CCS is no different; in each section of a CCS script (Script, Actions, Issues and Triggers), you use variables to define the values that CCS uses to run CLI commands and to match against output data from network devices.
NetMRI 's job engine recognizes several types of variables:
Well-Known Variables – A set of standard variables universally recognized by the NetMRI job engine in all scripts whereever they are called out. See the section Well-Known Variables for a list and brief descriptions of the well-known variables in the NetMRI system.
Script-Variables – User-defined variables that are used in sections of a script to allow interactive user/admin input during script execution. You define Script-Variables in the Script section of any script. (See the section Script-Variables: for more detail.) When a script runs, a Script-Variable prompts the user running the script to enter the value (IP address, user name, device name, etc...).
A Script-Variable can refer to lists in the NetMRI system (Configuration Management –> Job Management tab –> Lists) as an input type. (See and The getListValue( ) Function for more detail.)
Trigger-Variables – A special variable type, limited to Trigger sections, that is used to extract pieces of information from the command-line output resulting from an Action-Command attribute. Consult the topic Trigger-Variables: for more information.
SET variables – Custom, user-defined variables that can be declared only in specific Command scripting attributes. SET variables can also reference lists, which are two-dimensional tables of data that are installed into the Lists page in NetMRI. See Setting Variables in Command Attributes for more.)
