Pinned topic NMON 14i on crontab does not create/write to log file

‏2014-06-26T03:46:37Z | 14i cron crontab linux nmon

Running NMON 14i on SUSE SLES 11 64-bit.

My crontab:
# crontab -l
# DO NOT EDIT THIS FILE - edit the master and reinstall.
# (/tmp/crontab.XXXXbEOGJY installed on Wed Jun 25 21:01:15 2014)
# (Cron version V5.0 -- $Id: crontab.c,v 1.12 2004/01/23 18:56:42 vixie Exp $)
###NMON - Every 15 minutes during weekdays for 24h
00 0 * * 1-5 /local/nmon/nmon -x


So I see that cron started the command:

/var/log # cat messages | grep nmon
Jun 26 00:00:01 icsp101 /usr/sbin/cron[20038]: (root) CMD (/local/nmon/nmon -x)

# ps -ef | grep nmon
root     20141     1  0 00:00 ?        00:00:00 /local/nmon/nmon -x

However, when I check the filesystem where nmon is installed, there is no output file created:

/local/nmon # ls -l
total 240
-rwxr-xr-x 1 root root 240514 Sep 19  2013 nmon


I assumed that it would automatically create a file.  Do I need to specify this explicitly on the crontab entry? If so, how?

Thanks in advance,

    No idea why you assume nmon would create output into the directly in which is it install?

    Would you expect vi to save files to /usr/bin ?

    It saves the file in the current working directory just like ever other UNIX/Linux command.

    So have a look at the directory that cron run in - I would guess "/".

    If you want to set something different try running nmon with a -m /home/nigel"
