It really depends on what log level your application is logging at. If
you are
logging at 'INFO' level, then there will be alot of data to process. As
you
see, Hobbit implements a limit on how much log data it will parse. This
is a
good thing, at least in my opinion.

It all depends what is in your log... and why soo much data is being
written.
If they are all errors, well hobbit would be catching them telling you
there
are errors. Since this is not the case.. would guess your log has data
other
than errors.

Suggestions:
1. tune your application log settings so that only errors are written.
2. make use of the client-local.cfg log's setting of ignore. This will
allow
the hobbit client to identify what is an extraneous message, and ignore
it.
Per the man page:

The ignore PATTERN line (optional) defines lines in the logfile which
are
ignored entirely, i.e. they are stripped from the logfile data before
sending
it to the Hobbit server. It is used to remove completely unwanted
"noise"
entries from the logdata processed by Hobbit. "PATTERN" is a regular
expression.

I hope this helps you,

It's great to hear you guys, Hubbard and Steve, that you also find this
is a limitation (more than a bug), not wrong in my configuration.

I was thinking to modify source codes before, but it might be difficult
for me. I'll try your suggestions, thanks!

In my reply to your email, I said that this behavior "was a good thing". I do 
not find this to be a limitation at all. I offered you two possible 
solutions, were any of these applicable ?

The "limitation" really resides in whatever application is logging soo 
verbosely. Production level applications should have their logging limited as 
much as possible whenever possible, only logging indicators of errors. And 
whenever this isn't possible, make use of the IGNORE option.
