Read Text Log
Updated: May 13, 2016
Applies To: System Center 2012 SP1 - Orchestrator, System Center 2012 - Orchestrator, System Center 2012 R2 Orchestrator
The Read Text Log activity will read lines in a structured text log file. If you have log files that change names, you can configure the Read Text Log activity to read from the newest file in a folder that matches a file name pattern. The Read Text Log activity can be used to check a log for errors and then take corrective action on the server that is creating the log or send an email to an administrator to escalate the issue.
Important
For the Read Text Log activity to work correctly, every line in the text log file must begin with a timestamp.
Configuring the Read Text Log Activity
Before you configure the Read Text Log activity, you need to determine the following:
The log file name you are reading.
The timestamps format in the log.
Use the following information to configure the Read Text Log activity.

| The most recent file in this folder | Select and type the folder where the most recent file that matches the pattern that you specify will be read. You can also use the ellipsis (...) button to browse for the folder. |
| Matching this pattern | Type the file name pattern that will be used to find the log file that will be read. You can use the * and ? wildcards to specify the pattern. These wildcards behave in the same way as the Windows Command Prompt. |
