Definition File Format - UNIX

Definition File Format for UNIX

The format of the definition load file for events and event handlers follows the keyword / value-pair convention used for Universal Agent configuration files. However, because more than one definition can be specified in a load file, some additional conventions are used.

  • The begin_event and end_event keywords are used to mark the beginning and end, respectively, of each event definition entry.
  • The begin_handler and end_handler keywords are used to mark the beginning and end, respectively, of each event handler entry.
  • The begin_script and end_script keywords are used to mark the beginning and end, respectively, of any user script contained in the definition load file.

Lines that belong to the script must begin with the stmt keyword. Long stmt values that have to be split across lines can be done so using the + and - line continuation characters (as described in Configuration File Syntax). These lines will be accepted verbatim, and no script syntax validation will be done. Lines will continue to be added to the script until an end_script, end_handler, begin_handler, or begin_event keyword is read, or the end of the file is reached.

If a parameter's value contains spaces, it must be enclosed in single ( ' ) or double ( " ) quotation marks.

If quotes are to be saved as part of the parameter's value, enclose the value in single ( ' ) quotation marks quotes, and use a set of double ( " ) quotation marks to enclose the quoted value (for example, optname 'optval1 "optval2 optval2a" optval3').

The script keyword can be used in lieu of a begin_script/end_script block, in which case the contents of the specified file will be written to the event handler.

A sample definition file for UNIX is shown in the following figure.


Definition File Options

The Definition File options used in this example are:

Option

Description

event_id

Identifier that uniquely identifies an event definition record.

event_type

Type of system event represented by the event definition record.

comp_name

Event-driven UEM Server responsible for monitoring the event.

state

Event definitions that should be processed or ignored by UEM.

inact_date_time

Date and time at which UEM will stop monitoring an event definition.

triggered_id

ID of an event handler record that UEM will execute when an event occurrence is triggered.

filespec

Name of a file to monitor.

rename_file

Specification for whether or not UEM should rename a monitored file when an event occurrence is triggered.

rename_filespec

Specification for how a file should be renamed when an event occurrence is triggered.

handler_id

Identifier that uniquely identifies an event handler record.

handler_type

Type of process executed for the event handler, based on the contents of the USER_COMMAND and USER_SCRIPT parameters.

maxrc

Highest value with which a handler can exit to still be considered as having executed successfully.

userid

ID of a user account in whose security context the handler process will be executed.

script_type

Type of script statements contained in the action field of the event handler record.
