Viewing log files

At least two log files are associated with each grid node, one containing the system log entries and one or more containing the application-specific log entries. System log entries are those generated by the grid as the container for the application running in the node; examples might include bootstrapping information such as Grid and Java versions. Application log entries are those generated by the application and relate specifically to functionality in the application; an application may declare more than one log file. Because each application is running in one or more grid nodes, you can obtain valuable information about an application by viewing these log files. You typically access log files from the Applications, Nodes, or Log Files pages. Once a log file is opened, you can filter and search for relevant information. It is also possible to view log files of old nodes that are no longer running and to download log files in order to, for example, email them to someone.
