Engine and Daemon Logs

Each Engine and Engine Daemon generates its own logs. These can be accessed directly on Engines. However, because Engines are typically installed in several different machines, there are also methods to view logs remotely from other computers. The following procedures describe how to read Engine logs.

To directly view log files, look in the following directories in each Engine install directory

• Engine instance logs: install-dir/work/machine name-instance/log/*
• Engine Daemon logs: install-dir/profiles/machine name/logs/engined.log
• Also examine other .log files in the Engine tree

To read a remote Engine log in a scrolling window

Procedure 

1. Go to Grid Components > Engines > Engine Admin.
2. Select an Engine.
3. From the Actions list, select Remote Log.

This opens a window that displays the log for the Engine. Logging information is displayed as it is generated. This does not, however, display any prior logging history.

To access previous logs remotely

Procedure 

1. Go to Engines > Engine Admin.
2. Select an Engine.
3. From the Actions list, select Log Files.
4. A window opens with a list of links for each of the logs residing on that Engine, listed by date and time. You can do any of the following:
— Select an Engine Daemon or a particular Engine from the list in the upper left. This shows all of the log files on that Engine Daemon or Engine and their sizes. You can also type in the list box to quickly filter the list to partial matches.
— Click on a log file name and its content is displayed to the right in the window.
— Click the links in the upper right to download a ZIP archive of all log files on the host, a ZIP archive of all log files of an Engine Daemon or Engine instance, or a particular log file.

The Log Files window

You change the log level for Engines in Engine configurations, in the Log section. You can also set other logging options in Engine configurations, such as the maximum log size, and when log files are automatically cleaned.
