As a startup you should be using one of the many logging services out there - definitely don't waste time rolling your own or trying to install some open source log aggregator in an EC2 instance or something.
For error tracking, which is mostly what you'll care about, use a service like honeybadger, or rollbar, or whatever fits well with your stack.
For performance metrics use a dedicated service for that as well. NewRelic, or Skylight, or whatever works well for your stack.
