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.
