How To: Evaluate DSE Cassandra Clusters for Astra Migration
One of my co-works ssdatastaxrecently built a python tool called Astra Perseverance which executes against a diagnostic tarball from DSE Opscenter and provides some information needed for astra sizing. You can find the tool here. In this short how to I am going to show you how to setup your macbook environment and execute this script.
First setup your environment:
brew install python3 pip3 install pandas pip3 install xlsxwriter
Next install the tool:
git clone https://github.com/ssdatastax/astra-perseverance.git
Now execute the tool:
cd astra-perseverance python3 explore.py -p /Users/stevenmatison/Downloads/test/Cluster_1 -p /Users/stevenmatison/Downloads/test/Cluster_2 -p /Users/stevenmatison/Downloads/test/Cluster_3
After execution an Excel Spreadsheet will be located in each folder.
Notice I use python3 and pip3 here instead of documented python and pip. I had issues with existing python2 install not taking pandas or xlsxwriter.
