Change the naming convention of the output file
Hi

Currently we have nmon running on our Red hat Linux server.
The ouput file is now coming with the naming convention as "servername_160321_0010.nmon".

The output file naming convention has to be changed as "nmon_servername_daily_2016.03.21_00.00.00"

How can we do it ? Any suggestions please ?

Below is the nmon script scheduled in cron.
Code:
[root@servername nmonlog]# crontab -l | grep -i nmon
10 00 * * * /usr/bin/nmon_x86 -ft -s 60 -c 1440 -m /vol/nmonlog > /dev/null 2>&1

Below is the location where the output files are saved :

Code:
 [root@servername nmonlog]# pwd
/vol/nmonlog

[root@servername nmonlog]# ls -ltr | grep -i nmon
-rw-r--r-- 1 root root 3820143 Mar 11 00:09 servername_160310_0010.nmon

---------- Post updated at 02:15 AM ---------- Previous update was at 02:08 AM ----------

Below is the script info :

Code:
[root@servername nmonlog]# crontab -l | grep -i /vol/nmonlog/Unix_Stat

I am confused, you said below is the script scheduled in cron for nmon:-
Code:
[root@servername nmonlog]# crontab -l | grep -i nmon
10 00 * * * /usr/bin/nmon_x86 -ft -s 60 -c 1440 -m /vol/nmonlog > /dev/null 2>&1

But then you posted the code for another script which seems to be not related:-
Code:
[root@servername nmonlog]# crontab -l | grep -i /vol/nmonlog/Unix_Stat
0,5,10,15,20,25,30,35,40,45,50,55 * * * * /vol/nmonlog/Unix_Statistics.sh >/dev/null 2>&1 #CPU,Memory & Filesystem Monitoring

output file naming convention has to be changed
Hi

Sorry to confuse you. My Bad.

Below is the script scheduled in cron for nmon:
Code:
[root@servername nmonlog]# crontab -l | grep -i nmon
10 00 * * * /usr/bin/nmon_x86 -ft -s 60 -c 1440 -m /vol/nmonlog > /dev/null 2>&1

Please ignore the script named /vol/nmonlog/Unix_Statistics.sh.

The ouput file is now coming with the naming convention as "servername_160321_0010.nmon".

The output file naming convention has to be changed as "nmon_servername_daily_2016.03.21_00.00.00"

How can we do it ? Any suggestions please ?

You might try showing us the source for /usr/bin/nmon_x86 (which presumably creates and names the file whose name you want to change) instead of showing us the source for /vol/nmonlog/Unix_Statistics.sh (which seems to have absolutely nothing to do with this thread).

Hi

Thanks for your reply.

I can't open the file using # cat /usr/bin/nmon_x86 in putty.

Below is the output I get when I try to cat the file :

It is a binary file, I don't think you can change the output file naming.

As per nmon command manual:-
Code:
-f	Specifies that the output is in spreadsheet format. By default, the command takes 288 snapshots of system data 
with an interval of 300 seconds between each snapshot. The name of the output file is in the format of hostname_YYMMDD_HHMM.nmon

Hi Yoda

Thanks for the reply.
So the file comes as hostname_YYMMDD_HHMM.nmon.
After the file is generated and completed for a particular day, can we rename the file from "hostname_YYMMDD_HHMM.nmon" to "nmon_servername_daily_2016.03.21_00.00.00".
Say for example if the data is collected for March 21st, I believe when the day March 21st ends at 23:59 nmon creates a new file for March 22nd. So after the data collection started for March 22nd a script has to be put to rename the file for March 21st. Is there an option to schedule this on crontab so that the file gets renamed automatically everyday.
