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.
