The example in this section demonstrates how to implement brief-log, a custom SAF for logging only three items of information about a request: the IP address, the method, and the URI (for example, 198.93.95.99 GET /jocelyn/dogs/homesneeded.html).
To load the shared object containing your functions, add the following line in the Init section of the magnus.conf file:
Init fn=load-modules shlib=yourlibrary funcs=brief-init,brief-log
To call brief-init to open the log file, add the following line to the Init section in magnus.conf. (This line must come after the one that loads the library containing brief-init.)
Init fn=brief-init file=/tmp/brief.log
To execute your custom SAF during the AddLog stage for some object, add the following line to that object in the obj.conf file:
AddLog fn=brief-log
The source code for this example is in addlog.c file in the install_dir/samples/nsapi directory.
