Health, logs and crashes

How each app is doing in plain words, live logs with search, and crashes explained with their likely cause.

Health

Every minute OpsNexa Online measures each app: requests per minute, failed requests, response time (95th percentile) and memory against its limit. The app’s Overview says in plain words whether it’s healthy, needs attention or has a problem, with charts over 1 hour, 24 hours or 7 days, and a table view.

An app that keeps failing requests or nearly runs out of memory sends a notification.

Logs

The Logs tab shows live logs for production or any preview, and workers.

The Logs tab: live logs, search, errors only, and Explain the errors.
Logs: search, show only errors with their stack traces, or ask for an explanation.
  • Search the log.
  • Only errors shows just the errors, with their stack traces.
  • Explain the errors says what the current errors mean.
  • Developers can ask Claude for a deeper look, when AI features are on.

When an app crashes

When an app crashes and is restarted, runs out of memory, stops answering, or keeps crashing, OpsNexa Online keeps the last 200 log lines of that moment (secret values removed) and explains them:

  • a crash in the app’s own code, with the file and line from the stack trace;
  • an API key that was rejected, or a quota used up, at OpenAI, Stripe and others;
  • a database out of connections, or a service that doesn’t answer;
  • out of memory, with its limit, the week’s peak and whether memory kept growing.

The likely cause is in the notification, the latest crash is on the Overview, and the Logs tab lists recent crashes.

Vulnerabilities

  • The Security tab lists known vulnerabilities in the image the app runs, with how many have a fix and plain advice (rebuild on a newer base image, upgrade a library).
  • The Alerts tab checks the app’s dependencies and runtime every week for known vulnerabilities and versions that stop getting security fixes.
The Alerts tab: a known vulnerability in a dependency, with how to fix it.
Alerts: dependencies and runtimes checked every week.
