I use NMON (Nigels Monitoring) in AIX. It creates a daily nmon log with the naming conventions of:
hostname_YYMMDD_0000.nmon
or
myserver_080902_0000.nmon
What I am interested in doing is creating a script that is executed on the first of each month to clean up last months *nmon files. . .what I mean by clean up is that it would create a directory in the format of yyyymm and move all of last months files in that newly created directory.
The problem is that each hostname is of different lengths (since I would be using this on different hosts). . .so it's difficult to use the "cut" command because the length of characters will differ from box to box.
I have a script which would monitor a given directory and delete any files which are older than 10 days. I was going to set the 10 crob jobs to perform this operation for 10 different directories (some are actually sub-directories), but my boss doesn't like that idea, so I need to do that in one...

Hi All,
First of all, I am a DBA and not an AIX admin. I am new at using this NMON tool.
In interactive mode, I can start nmon, push 't' to have the list of process with their statistic (ie cpu% etc.).
I would like to know if there is a way to redirect that screen output into a log... (1 Reply)
Hello,
How can I know if ORACLE Database is running slow due to Memory or due to processing power ?

crontabs
CRONTABS(4) Crontabs users' Manual CRONTABS(4)NAME
crontabs - configuration and scripts for running periodical jobs
SYNOPSIS
run-parts [--list|--test]<directory>
DESCRIPTION
Crontabs is a historical name for the run-parts script and the system crontab. The run-parts script runs all executables in the specified
directory. Run-parts runs all executables in the specified directory. The execution of files can be allowed or denied by creating file
jobs.allow or jobs.deny which worked similar as other allow/deny config files. The file must be created in the specified directory.
--list print names of all files (not limited to executables), but don't run them. This option can't be used with test option.
--test print names of files, which would be run.
Randomization of jobs can be configured in the /etc/sysconfig/run-parts file. To enable randomization of jobs, set the RANDOMIZE
parameter to 1 and set the RANDOM parameter to an integer which determines a random seed. Additionally, you may configure the RAN-
DOMTIME parameter (again, by specifying an integer) to provide an additional level of randomization. Jobs are not randomized when
the RANDOM and RANDOMTIME parameters are set to 0. Values in these two parameters must be set to 1 or larger to provide a good
enough randomization.
Randomization of cron jobs can be useful for shared networks, where multiple cron jobs executed at once can cause spikes in traffic,
especially during daily jobs. With randomized jobs, the workload is evenly distributed throughout the day.
EXAMPLE OF CONFIGURATION FILE
RANDOMIZE=1
RANDOM=4
RANDOMTIME=8
Historically the crontab file contained configuration which called run-parts on files in cron.{daily,weekly,monthly} directories. These
jobs are now run indirectly through anacron to prevent conflicts between cron and anacron. That means the anacron package has to be
installed if the jobs in these directories should be running. Refer to the anacron(8) how to limit the time of day of the job execution.
EXAMPLE
/etc/cron.daily/jobs.deny could contain for example 0logwatch which forbid execution of this script.
