First, remember the option we mentioned before, to list the current settings of all of analog's variables. To get this, just put -settings on the command line, or PRINTVARS ON in one of your configuration files, along with your other commands. Then analog will produce the list of settings instead of running in the normal way.
DEBUG ONyou get all the debugging. (And DEBUG OFF turns it off again.) You can also get just certain categories of debugging. The categories are
DEBUG FSwould give you information about file opening and closing, and what was in each logfile, but none of the other sorts of debugging. Each line of debugging information is prepended with its code letter. You can also specify
DEBUG +CDto add C- and D-category debugging, and
DEBUG -CDto remove them.
The WARNINGS command acts similarly. As well as WARNINGS ON and WARNINGS OFF, there are warnings in the following categories.
You can also use command line abbreviations for these commands. The DEBUG command is represented by +V (for ON), -V (for OFF), +VFS (to select options FS), +V+FS (to add those options), and +V-FS (to remove them). Similarly the WARNINGS command can be given by +q, -q, +q<options>, +q+<options> or +q-<options>.
PROGRESSFREQ 20000 # saythen analog will produce a little message after every 20,000 lines it reads from the logfile. This is useful to determine whether the program has really stopped or (as is more likely) is just being slow for some reason (such as using DNS lookups).
There is just one more section about analog's configuration commands and command line arguments, but it's a rather long one, on the form interface. (This is a way of running analog by selecting options from a web page.) You might prefer to go straight onto the section on What the results mean.
