Universal Agent Messages and Codes

All Universal Agent components have the same message facilities. Messages - in this context - are text messages written to a console, file, or system log that:

  • Document the actions taken by a component.
  • Inform users of error conditions encountered by a component.

Each Agent component writes messages unique to that component.

Message Information​

These pages identify and describe those messages. For each message, the following information is provided:

  • Message ID
  • Message text
  • Description
  • Severity
  • System Action
  • User action
  • Component

Message Groups​

On these pages, messages are grouped 100 per page. To find details for a specific message, select the appropriate message group.

Message ID​

Each message is prefixed with a unique message ID that identifies the message.

The message ID format is pppnnnnl, where:

  • ppp is the product category identifier:
    • UAG (Universal Automation Center Agent Component)
    • UNV (All other Universal Agent Components)
  • nnnn is the message number unique to that message.
  • l is the severity level of that message (see Severity Levels, below).

Severity Levels​

There are six severity levels of Universal Agent messages. The severity level is based on the information provided by those messages.

Severity Level

Description

A (Audit)

Messages document the configuration options used by the program's execution and resource allocation details. They provide complete description of the program execution for auditing and problem resolution.

I (Informational)

Messages document the actions being taken by a program. They help determine the current stage of processing for a program. Informational messages also document statistics about data processed.

W (Warning)

Messages document unexpected behavior that may cause or indicate a problem.

E (Error)

Messages document program errors. They provide diagnostic data to help identify the cause of the problem.

D (Diagnostic)

Messages document diagnostic information for problem resolution.

T (Alert)

Messages document a notification that a communications issue, which does not disrupt the program or require action, has occurred.

Return Codes​

A return code - referred to as exit code on some platforms - is an integer value returned by a component to indicate success or failure of that component.

See Return Codes for descriptions of the return codes that can be produced by the different components that comprise Universal Agent.
