Monitor PostHog with MrCron

MrCron pulls active-user and event counts from PostHog every 5 minutes so you can watch product engagement on the same dashboard as your errors and deploys.

How MrCron monitors PostHog

  • Active users on rolling 24h and 7d windows per project.
  • Session count for the last 24 hours.
  • Top event names by volume for the last 24 hours.
  • Sparkline history for active users on the project overview.
  • Auth-failure detection with an amber Rotate key CTA when the personal API key stops working.
  • Alert rules that fire on active-user drops via any notification channel.

What you will see

Active users (24h / 7d), session count, top events on your project page.

Auth flow: OAuth. Credentials are stored encrypted at rest with AES-256-GCM and never returned to your browser.

Frequently asked questions

What PostHog credentials does MrCron need?
A personal API key with read access to your project. MrCron stores it encrypted at rest and never returns the key to your browser.
Which PostHog metrics are stored raw versus rolled up?
Raw snapshots are kept for 7 days. Longer history is rolled up hourly, then daily, so charts stay fast even on year-scale windows.
Does MrCron cover self-hosted PostHog?
Yes. Configure the integration with your self-hosted PostHog host URL and the same personal API key format works.
Can I alert on a drop in active users?
Yes. Create an alert rule on the posthog_active_users_24h metric with a threshold below your baseline and route it to any channel.
