I'm a solo developer

To a first approximation, monitoring tools are built for teams, projects running at scale, and for systems where falling over matters at scale. And monitoring as a "best practice" is good engineering practice only in those contexts.

You don't have that context and probably should resist the temptation to boilerplate it and considering it as moving the project forward. Because monitoring doesn't get you customers/users; does not solve customer/user problems; and nobody cares if you monitor or not (except assholes who want to tell you you are morally failing unless you monitor).

Good engineering is doing what makes sense only in terms of the actual problems at hand. Good luck.

I wasn't building one exactly for me, but I believe not all devs have a team available to monitor the deployments for them...and sometimes centralized observability could really be a plus and ease the life for a developper....just being able to vizualise the state of your multiple vps deployments from your single pc without logging into you provider accounts should count for something I belive....this is without any form of anomaly detection or extra advice about your deployment state...I wanna believe this is useful but again the critique is welcome

Agreed... while monitoring isn't everything, not just alerts, but a dashboard and reports can provide insights and early warnings before things start falling over.

A single 80% CPU spike isn't anything to worry about by itself... but if it is prolonged, frequent and accompanied with significant influence on p95/99 latency and response, it could be a critical warning that you need to either mitigate an issue or upgrade soon.

I would be more inclined to set limits on response latency, or other metrics that would be impactful to users as to what is tolerable, and use that as critical alert levels. The rest you can use reports on to get say hourly or half-hourly windows in terms of where performance hits are, what the top values were for latency in addition to p95/p99, etc.

Thanks tracker...very insightful
