LOGFILE CONFIGURATION ENTRIES

A logfile configuration entry looks like this:


    log:/var/log/messages:10240


The log:FILENAME:SIZE line defines the filename of the log, and the
maximum amount of data (in bytes) to send to the Xymon server.

 
what is the MAX SIZE value possible - iow constrained by what ?

logfetch monitors the bottom X chunk of the file - true or false ?


if I get output like below - what can I conclude?  


[msgs:/var/log/rmsupload.log]
<...SKIPPED...>
SIZE being set to 31856
200 SITE command was accepted
local: /ftpstage/rms/rmsupload17896.t remote: 'tran.rmsrpt32(+1)'
227 Entering Passive Mode (161,195,160,202,88,21)
125 Storing data set TRAN.RMSRPT32.G0008V00


<...SKIPPED...>
I had more data than could fit in the chunk? iow I may have missed interesting stuff!


SIZE being set to 31856  
means what? how is this value decided?


Thanks!

This is from the FTP server you're using.  Nothing to do with Xymon.

MAXBYTES is read into an "int" (signed) variable, and copied to another of
type "off_t".  I think the size of these types is architecture-dependent,
but you can expect these to be at least 16 bytes, which should mean a
number up to 32767.

I'm not a C programmer, so someone else might correct me.  Also, there may
be other constraints on how MAXBYTES is used.
