The single source of truth for all things zPlanner related.

What is zPlanner

zPlanner is a tool that is designed to monitor disk change rates to VMware virtual machines. zPlanner leverages the PowerCLI interface to get data from vCenter and store it in a local MySQL database. This data is then manipulated and presented using Grafana.

The intended purpose of zPlanner is to help architect the number of Zerto Cloud Appliances that are required as well as how much bandwidth is needed to replicate a workload.

zPlanner is a combination of two parts, there is code that makes zPlanner work, as well as a virtual machine that has the required packages to run the code from GitHub. In order to deploy zPlanner you should download the zPlanner appliance and it will download the latest zPlanner updates during configuration.

Let’s work together to make this project even better!

If you look at the code on GitHub and see a way to make it better please submit a pull request.

If you have an idea for a feature, let me know, any and all feedback is welcome.

In the future, I’d like to move from PowerCLI to Python and the VMware SDK to improve scalability, so if you know anything about either of those subjects I’d love to collaborate with you as well.


Simple version

zPlanner is written and maintained by me, not Zerto. zPlanner uses read-only access to your vCenter server and has been rigorously tested to make sure it won’t hurt anything. However, use it at your own risk. I take no responsibility if you hurt your environment with it.

Feel free to view all of the code that zPlanner uses on my Github repo here http://github.com/Zerto-TA-Public/zPlanner and decide for yourself if it’s safe to use.
