Specifies the logging directory, where the log file and logging-related support files are stored. Optional Boolean attribute. Specifies whether logging is enabled true or disabled false for a site. The default value is true. Optional uint attribute. Specifies the number of events to be stored in the buffer before they are flushed to the log file.

A lower number will cause events to be flushed more quickly, at the cost of performance as a result of a greater number of disk operations. Reduce this value for more real-time troubleshooting, increase it for performance. A value of 0 specifies that the flush will occur at the default maximum of 64k. The default value is 0. When false, a new log file is created based on UTC.

The default value is false. Optional flags attribute. Specifies the categories of information that are written to either the log file when you use W3C Extended log file format or to the ODBC data source during logging events for a site.

Log the query, if any, that the client was trying to perform. For example, Default. Log the name of the authenticated user who accessed your server. For more information see web statistics software.

A good log analyser will be able to retain the basic statistical information in it's own database after the raw log files have been deleted.

Is it safe to delete log files? Yes, log files can be safely deleted. However, before you delete all your log files, it might be worth keeping the most recent content of the most important log files in case you need to troubleshoot any problems. What are the different types of logs? Types of logs Gamma ray logs. Spectral gamma ray logs. Density logging. Neutron porosity logs. Pulsed neutron lifetime logs.

Carbon oxygen logs. Geochemical logs. Why do we need log files? Log files are also important to keeping track of applications that have little to no human interaction, such as server applications. Log files can also be used to correlate data between servers, and find common problems between different systems that might need one major solution to repair them all.

What is a system log? Note, I've added some space for clarity, and changed the IP number to Different servers have different log formats. Nevertheless the data in this log fragment is pretty typical of the information available. Let's look at one line from the above fragment split for easier viewing.

This is the IP address of the machine that contacted our site. The ". As regards privacy, you can't prevent this information being given away. Of course how easy it is to associate you with your IP address is another matter.

In this case all I can say is "someone at bellglobal. It's quite likely that were you to visit again tomorrow the "ppp
