Detailed Description

This class provides the hooks to control the output produced by any of the network services.

Depending upon when this service is invoked and with what flags, the output of other network services can be controlled. The output can be streamed to stderr, to a file, to a logging daemon, or it can be set to be "silent". If logging records are output to a file, the file can be set to a maximum size and repeatedly split into new files. The log file size can be limited at any logging point (i.e., application, client logging daemon, or server logging daemon) by specifying the -i

Parameters:

sample_interval_in_secs	and -m
max_size_in_KB	options for the Logging_Strategy class in a svc.conf file.

By default, two logfiles are generated. It's possible, however, to generate as many logfiles as necessary to store all the information. To achieve this, it is only necessary to indicate the maximum size of the logfiles via the -m option and the process will generate automatically the logfiles. You can control the total number of logfiles created via the -n option.

By using the -o option we can also choose the mode of organization of the files, e.g., the first one is the normal used in Unix systems (when cron rotates the logs it keeps the lowest number the most recent one), the second is for increasing speed (we only create a new log file, and don't rotate the others (fewer accesses to disk)).

By default, the ACE_Logging_Strategy uses the singleton reactor, i.e., what's returned by ACE_Reactor::instance(). If you want to set the reactor used by ACE_Logging_Strategy to something other than the singleton reactor you'll need to get a pointer to the ACE_Logging_Strategy instance and do this

ACE_Reactor my_reactor; ACE_Logging_Strategy *logging_strategy = ...... // Get instance.

logging_strategy->reactor (&my_reactor);

and then logging_strategy will use your reactor. If you're dynamically linking the ACE_Logging_Strategy then you can use the ACE_Dynamic_Service template to get a pointer to the ACE_Logging_Strategy.
