Presumably you can have a cluster of grepping machines. I wonder how it scales compared to the millions you pay for Splunk.

is your business' core competency building a distributed grep or actually selling useful stuff?

Well, according to what people write in this thread, a distributed grep or some other way to organize a decent central logging system might be a necessary part of the core competency. Because if they buy splunk instead, they might go bankrupt.

You don’t have to be splunk to make money out of distributed grep but it turns out to not be that easy… as proven by the fact that there are quite a few competitors

My core competency is saving the business tons of money, so that they can pay me.
