Operation: Read Messages

The Read Messages operation retrieves a list of all stored log messages for a given process to view the history of messages (including timestamp, message type and message content) and to troubleshoot issues that occurred. This operation expects a PID or PUID as input from a process with the operation Log Message or Log Batch Message.

Attributes can be used to filter for log messages:

The Message attribute can be used to filter for log messages with the specified search text.
The Key attribute can be used to filter for log messages with the specified key.
The Level attribute can be used to filter for log messages with the specified level.

Input

The adapter expects the following XML structure as input:

Example

XML

<Element>
	<PID></PID>
	<PUID>D4813FA1-EC9E-475D-81EB-3B69026346E5</PUID>
	<Message>age</Message>
	<Key>A</Key>
	<Level>INFO</Level>
</Element>

The following elements can be included in the input:

Attribute	Description
`PID`	ID of the process for which the messages are retrieved
`PUID`	PUID of the process for which the messages are retrieved
`Message`	The `Message` attribute filters the result of the `Read Messages` operation for log messages that contain the specified search text. If the `Message` attribute is empty or no matching search text is found, the attribute is empty in the output. Possible value: Any string (string, case-insensitive).
`Level`	The `Level` attribute filters the result of the `Read Messages` operation for log messages that contain the specified search text. If the `Level` attribute is empty or no matching search text is found, the attribute is empty in the output. Possible value: Any string (string, case-insensitive).
`Key`	The `Key` attribute filters the result of the `Read Messages` operation for log messages that contain the specified key. If the `Key` attribute is empty or no matching search text is found, the attribute is empty in the output. Possible value: Any string (string, case-insensitive).

Output

The adapter generates an XML document as output with PID, PUID, timestamp, key, level, and content of the log message.

Example
