hmm, this will make it harder to track down, anything you can think of that's different between ones where it works and ones where it doesn't?

I couldn't get ReadMode 1 to work for java exceptions so I found some
rsyslog documentation to use ReadMode 2  for indent and that actually works
me.

yeah, that's what the readmode was created for :-)

as a test, could you leave it with the default readmode (which will make each line of the java code be a different log message) and see if you have the same problem, just to rule out of that is part of the problem?

Where is the best place to post debug logs?

you can't send them to the list, but private e-mail to Rainer and/or me will work (Rainer is much more familiar with things, but is short of time)

posting them on dropbox or something like that and sending a link can also work.

Subject: Re: [rsyslog] Imfile sporadically sending messages

It's  very unlikely that the problem is keeping up

read mode 2 means that it can't consider a log paragraph read until it
has the
beginning of the next log message (it doesn't know if there is more data
pending on the log it's got)

I think that Rainer will need to take a look at this, is there anything
showing
up in a debug run?

Just to chime in that I am unfortunately extremely busy at the moment. I
can have a quick lock at the debug log, but not more, probably for the next
2 weeks. Sorry for that,
Rainer

I use rsyslog and the imfile module to watch some application logs and

imfile is sporadically sending messages to the remote server. On a few
servers it works as expected but it isn't consistent.

I receive about 191 new events (lines) per minute and its only sending
a few messages every couple of minutes.

A tcpdump confirmed the all messages are not being sent from the host.

rsyslog-5.10.1-4.el5.centos.x86_64.rpm

ReadMode 2 works indented and not 1 not like the doc says.
http://www.rsyslog.com/doc/imfile.html

Is it possible that it can't keep up? I watch the state files and it
doesn't seem like they update at all after they are created.



#Sample Config
$ModLoad imfile

#Watch java app log with multiline support $InputFileName
/logs/app1.log $InputFileReadMode 2 $InputFileTag app1-log:
$InputFileStateFile state-app1-log
$InputFileFacility local6
$InputFileSeverity debug
$InputRunFileMonitor

#Watch app access log
$InputFileName /logs/app1-access.log
$InputFileTag app1-access:
$InputFileStateFile state-app1-access
$InputFileFacility local7
$InputFileSeverity debug
$InputRunFileMonitor
