LM Instance Auto Balance Collector Tool

I have a simple (read:basic) Excel spreadsheet that does this.

You could do the same, or I'll happily share the spreadsheet if you'd like.

It's based on this page:
https://www.logicmonitor.com/support/collectors/collector-groups/auto-balanced-collector-groups
And specifically, this equation from that page:
Number of instances = (Target_Collector_mem/Medium_mem)^1/2 * Medium_Threshold

The spreadsheet (which was only created for me, so like I said, it's basic) requires you to enter the current number of instances on each collector and the collector memory size, and it calculates the rebalance threshold. 

In my testing, it works well.
