The document discusses three common mistakes companies make with application monitoring: 1) Not monitoring the entire system leading to blind spots, 2) Monitoring arbitrary metrics that don't provide useful information, and 3) Viewing monitoring as someone else's problem rather than prioritizing it themselves. The author is from New Relic and seeks to educate on best practices for effective monitoring.
