You win! I have about 50 nodes at the moment. :)
We use the Elastic Stack for collecting the logs from all the nodes. I'm always requesting changes because I am not the Administrator for the Elastic Stack products.
The Elastic company seems to be very good with their support. They offered one local class and it was very informative. Elastic has been difficult for me because I'm not an Administrator for the Elastic products and I did not fully know the options available to me. So I make requests and in most cases they have been done. I'm sure there is a better way for me to use the Elastic Stack, but it's an evolving process at the moment.
I'd be very interested to know how everyone else uses it too.
