Mat has updated the DIY Heatmaps for EMC CLARiiON and VNX arrays to version 4.01. You can get it from the Utilities page. Any and all feedback welcome.
Updates and Changes to the script
- Add database storage / retrieval for performance stats. The database size will be approximately 2.1 x the size of the NAR file based on the default interval of 30 minutes. On my PC it took a bit over 9 hours to process 64 NAR files into a database, the NAR files were 1.95GB and the resulting database was 4.18GB. However running the script over the database to produce a heatmap only takes seconds.
- Changed to use temporary tables for transitional data. This should slightly reduce the size of the database file, as the temporary data is not written to disk.
- Changed the way the script processes multiple NAR files, the script previously bunched all NAR files into a single naviseccli process, this was problematic if you were processing multiple large NAR files, the script now processes them one at a time.
- Add command line options:
–output_db Output the processed NAR file to the nominated database
–input_db Use the nominated database as the source of data for the heatmap
–s_date Specify a start date/time must be in the format (with quotes if specifying date and time “mm/dd/yyyy hh:mm:ss”
–e_date Specify an end date/time
–retrieve_all_nar When retrieving NAR files from the array, you can now retireve all nar files (it wont overwrite files already downloaded)
–process_only_new If you are downloading NAR files, only process files that haven’t been downloaded previously
–max_nar_files Set the maximum number of files to download and process
Please let us know if you find any bugs or problems with the script, or if you have any further suggestions for changes and enhancements.
