Show HN: Is PagerDuty useful with an uptime monitoring service?

I am so confused about the PagerDuty app whether or not it is useful for future Odown users,

As the founder of Odown which is a simple uptime monitoring service, it's very important to add all kinds of tools that can help our customers, but right now we're starting with the highest priority integrations like Slack

So if you have used an uptime monitoring service like Odown or any other app before, do you think PagerDuty should exist in any basic monitoring app?
