Celerra help running a perl script on control station

I am able to get this running but I am curious does the collect-perf.pl turn collection on?   So do I need to run that then wait to run the collect.pl until a reasonable amount of time has past?   Also does the collect.pl turn the performance data collection off?  I ran them more or less back to back and only ended up collecting 4 intervals in the data that was collected.  Does anyone know for sure how it works?

Just found the answer.  By default the collect-perf.pl runs for 2 days. 

300 second intervals (5 minutes) for 576 intervals (2 days)

When running collect-perf.pl, make sure to keep your ssh terminal open. Otherwise the script will terminate when you close the ssh window.

You may also be able to nohup the command, to prevent it from terminating.

I use WINSCP to upload the files to the control station, then i use PUTTY to connect and run the commands.

No.  You only call nohup ahead of the command you wish to run.  You might need to use "./" in front of the command you're trying to run, because most likely it is not in the local path.  Here's an example:

[nasadmin@vnxtest ~]$ cd /home/

[nasadmin@vnxtest ~]$ ./mailtest.pl nohup &

[1] 11782

Without the ./, I get:

[nasadmin@vnxtest ~]$ mailtest.pl nohup &

[1] 13358

bash: mailtest.pl: command not found

I would bet that running the command the way you specified has no output in the nohup.out file.

Let us know if that helps!

Guys a quick question if I run the command with nohup perl collect-perfdata.pl the command does not execute and gives an error no shuch command found

However if I run it as perl collect-perfdata.pl nohup I am able to execute the command. Would this still work the same way with nohup at the end instead of at the start?

Thanks for the reply Karl. The putty session did close, however the data collection did not stop. So I guess I could achieve what I wanted to.

I however have another problem while trying to retrieve the logs from the control station.

When I run perl collect.pl --full --outputdir /your_local_output_directory

I get the below error.. Any input is appreciated.

You're trying to write to your local workstation hard drive (C:\ drive).  This won't work.  You have to write the file to the local filesystem on the Control Station (for example, /tmp or /home/nasadmin), then move the file via FTP, SFTP or SCP to your local workstation.

Exactly what I tried now created a directory called outputs under home/nasadmin

I am logged in as nasadmin..

This is what I get

Actually, that output looks correct to me.  Did you look inside the outputs folder?
