My friend Mat has developed a pretty cool script that can make pretty pictures out of Analyzer files from CLARiiON and VNX arrays. He’s decided to release it to the world, so you can download it here. I’ve also added the following instructions to a pdf document available here. Here’s a sample output file from the script. He’s after feedback as well, so send it through and I’ll make sure it gets to him.
The heatmap script allows you to generate heatmaps of various metrics over time from NAR files generated from EMC Clariion/VNX arrays.
- This script was developed and tested using Strawberry Perl (v5.12.3), but there is no reason it won’t work with other flavours or versions of Perl, but it is possible that other perl modulse other than the one listed below may need to be installed
- It requires the Text::CSV module for Perl. Available here http://search.cpan.org/CPAN/authors/id/M/MA/MAKAMAKA/Text-CSV-1.21.tar.gz , if you can get cpan working (run “cpan Text::CSV”) it will be easy to install, otherwise you’ll have to do it manually …
Unzip the files into eg C:\Text-CSV-1.21 and run the following commands
- The script uses the Microsoft tool logparser.exe to manipulate various CSV files available here http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=24659
- The script uses naviseccli to convert the NAR files into CSV files.
- At the moment the script will only run on a windows server/PC due to its reliance on the logparser tool, if people are interested I will investigate other tools available in the Linux/Unix worlds.
- The default min/max figures that I am using may be unrealistic, I am by no means an expert in analysing the performance of an array, any feedback is welcome.
The following are the command line options available for the script
These options allow you to set the location of the various 3rd party binaries that the script relies on
The interval that the analyser stats are averaged down to, ie 1800 seconds will set the average interval to 30 minutes
The input NAR file(s), more than one NAR file can be specified
The filename of the generated HTLM output file, the default is HEATMAP.HTML
The name of the array, this is for reporting purposes only
Generate a summary for each attribute type, displaying minimum, average and maximum figures for each metric
Disk Utilization (%)
Disk Total Throughput (IO/s)
SP Utilization (%)
SP Total Throughput (IO/s)
This generated a mash table for each metric type (currently only Storage Processor and Disk), averaging each of the metrics for each type down into a single table, allowing you to combine multiple metrics into a single table.
The –mash option will display the mash-up table alongside the selected metrics, and the –mashonly options will only display the mash-up tables.
–array_ip <ip addresS>
This option allows you to query the array (as it is currently configured) to determine drive types (currently only SATA II, FIBRE CHANNEL, and SATA II SSD), currently this options only affects the IOPS calculations for drives.
–user_id <user id>
These options are only used in conjunction with the –get_drive_type option, if you have cached credentials for the array configured then these options should not be necessary.
This option is only used in conjunction with the –get_drive_type option, it will display another drive table, and allow you to view the different drive type, drive size, pool and RAID Group layouts.
This option is only used in conjunction with the –get_drive_type and –display_drive_type options, it will highlight the corresponding disks in the other heatmaps, it will also allow you to select all of the drives that have the same attributes as displayed by the –display_drive_type option.
These options allow you to generate a configuration file, using the –generate_config option, this will generate a config file with all of the default attributes, and to use a configuration file using the –config_file option.
This option will display the following help information.
Usage: heatmap.3.010.pl <options>
Where options can be the following:

Running the script without any –nar_file options will result in the script prompting the user to supply NAR file(s)
Allows you to select which attributes you want to display on the heatmap.
