Ask HN: How could application monitoring be better?

Hi everybody. Full disclosure: I am trying to validate a startup idea. Please help :)

I believe there is a gap in the market for affordable application noting. The current solutions (new relic, datadog) seem out of reach for most startups/individuals/small businesses.

Am I right or not really? Is there something else that bugs you about these APM tools? Do you wish they did something else?

Thanks in advance! Chris
