Dynamic log import

EELS can automatically import records from proprietary log files when those log files grow by a given amount.

The configuration information for dynamic log import is contained in a dynamic-import parameter block. Multiple dynamic-import blocks are allowed within a single configuration file. The parameter block contains the following tags:

• filename

• filter

• growth

The script must import the records in a format that EELS can use. For information on how to create such a script, see ``Importing external log files''. One feature that is not addressed by the dynamic-import parameter block is that of how to keep track of what has already been imported. It is the responsibility of the import script to keep track of what has already been imported from a particular script. There are several methods you can use to do this:

• after importing the records from the log file, rotate the name, for example, from log_file.err to log_file.err.001

• keep a running total of the size of the log file at the moment it is imported, so that the next time you import the file, you know how many bytes or records to skip

• delete the contents of the log file; if you are confident about this, empty the log file after you have imported it into the EELS database
