How do you monitor social media and community engagement?

Hey all, I'm cofounder of a startup in the Kubernetes space with a major open source offering (robusta.dev). I need a way to track reach + community engagement on social media.

Our community is on fire and people are writing blog posts and doing review videos about us. But I don't have a single graph right now that tracks this. We already raised our seed round but we're getting questions from major VCs today about the growing community. It's important we have something numeric that we can track and show for the A round.

Any recommendations for tools to track this?

edit: to be more specific, we'd like to track LinkedIn, Twitter, Slack statistics, social media mentions, YouTube views, and GitHub engagement. Open to more ideas for what we should track too. We do not need to track specific users - we just need the overall statistics.
