How to merge multiple NAR files

I have come up with a script to accomplish that.  I created it for my needs, so it's not polished or anything, but it gets the job done.

I create three folders and call them Files, Merged and Script.

The nar files go in Files, and the perl script goes in Script. The output goes in Merged.  The script assumes that you have the latest naviseccli installed and that it is defined in the path variable in Windows.

You will need to point to the right folders in the perl script.  Maybe the code is not optimized, but it has helped me out a lot.

EDIT:  The slashes and comments didn't come out right on the forum, and I don't know how to attach a perl script file. So if you are having trouble running this, send me a message through this forum.

$narfiles_dir = " $mergedfiles_dir = "" @file_list =(); $number_of_files = ""; opendir DIR, $narfiles_dir; while ($filename = readdir(DIR)) { if ($filename eq "." || $filename eq "..") { next; } else { push (@file_list, $filename); } } closedir(DIR); $number_of_files = @file_list; #$output = $mergedfiles_dir."test.txt"; #open (ABC, ">$output") || die ($!); for ($count = 0; $count <= ($number_of_files - 1); $count++) { if ($count < 2) { $a = "naviseccli analyzer -archivemerge -data ".$narfiles_dir.$file_list[$count]." ".$narfiles_dir.$file_list[$count+1]." -out ".$mergedfiles_dir."merged".$count.".nar"."\n"; print $a."\n"; system($a); $count++; } else { $b =  "naviseccli analyzer -archivemerge -data ".$narfiles_dir.$file_list[$count]." ".$mergedfiles_dir."merged".($count-2).".nar"." -out ".$mergedfiles_dir."merged".($count-1).".nar"."\n"; print $b."\n"; system($b); } } #close (ABC);

I had a feeling you would say that! :-(

Thanks

The merged file does however have all of the data points, so if you wanted to dump them out to a .csv say and import them to excel, you can manipulate the data from there. Also if viewing in Navisphere you can specify shorter time frames when opening the files and the averaging will be less than viewing the file as a whole.

That is what I do. I merge a week's worth of files, display it in Navisphere analyzer and for each RG or lun I want to focus on, I do a "save as" and save the data as a CSV file. Then I use Excel to create graphs, or find average, standard deviation, etc.

First, thanks very much for posting this method, I know that a lot of us that work with NAR files will appreciate this.

Second, when you merge two NAR files together, it does in fact get all the data points, it just can't display more than 156 in the Analyzer GUI - the points are still all in the merged file.

Hi,

I want to try to merge multiple nar files with the script but i have an error when i try to run the command line :

NaviSECCli.exe analyser -archivemerge -data D:\FILES\CK200074200302_SPB_2009-12-16_18-09-16-GMT_P01-00.nar D:\FILES\CK200074200302_SPB_2009-12-16_20-45-16-GMT_P01-00.nar -out D:\MERGED\test.nar

Security file not found.  Already removed or check -secfilepath option.

Can you help me please ?

hello

skip cli, try it via Navisphere GUI, it works for me,

naviseccli is expecting to find username, password and scope information - which you are not providing in your command. There are two options -

1. You can create a securityfile with the default username, password and scope. Once you do this, naviseccli will try to use this information whenever you issue a command from that host.

2. You can provide the login credentials along with the individual CLI command.

Just found the old thread I'm also wanting to merge a large number of nar files

is there a new method to do this now? or a link to the script?

Read this: www.50mu.net

This blog post covers the retrieval, merging and the steps to take to analyze performance.

I se4arch through that site and could not find the article you mentioned.  Can you post the exact link?

Thanks,

On a machine that has naviseccli installed:

Create a directory called c:\nar_files & then copy your nar files there.

Create another directory called c:\nar_merged & then copy one nar file there and rename it temp.nar

Create a third directory called scripts.

Put this batch file into the scripts directory & run it.

echo on

del c:\nar_files\nar_list.txt

dir c:\nar_files /w /p /b > c:\nar_files\nar_list.txt

for /f %%i in (c:\nar_files\nar_list.txt) do (del c:\merged_files\output.nar

     naviseccli analyzer -archivemerge -data c:\merged_files\temp.nar c:\nar_files\%%i -out c:\merged_files\output.nar

     del c:\merged_files\temp.nar

     copy c:\merged_files\output.nar c:\merged_files\temp.nar)

It takes a while to run.

But when done rename output.nar to match the array and date and open in analyzer.
