Monitor logs

Summary: Logs for Functions and Object Storage live on the Monitoring page, split across the Functions and Storage tabs (one viewer per service, no combined view). Filter by level (DEBUG, INFO, NOTICE, WARN, ERROR, FATAL) or service name, search log bodies, poll for new lines with Go live, and download the current view as a .log file. Logs are retained for 3 days.

View, search, and download logs for Functions and Object Storage

The Monitoring page shows service logs in two tabs, Functions and Storage. Each tab is a log viewer for that service on the current branch; there is no combined, all-services view. The two tabs share the same controls, described below.

  1. In the Neon Console, select a project and branch.
  2. Go to Monitoring.
  3. Open the Functions or Storage tab.

Each tab shows logs from every function or bucket on the branch. Narrow to a single service with the service name field (see Scope by service).

You can also jump straight to a service's tab without visiting Monitoring first:

  • From the Functions list, open a function's menu and select View logs.
  • From the Object Storage bucket list, open a bucket's menu and select View logs.

Both land you on the matching tab.

Each row shows a timestamp, a level, and the log message. Expand a row to see its full context: timestamp, severity, entity_type, scope_name, and service_name. entity_type identifies the kind of service a line came from (function or storage); service_name identifies the specific one (neon-function/<slug> or neon-storage/<bucket>).

For what these fields mean for a given service, and how each service maps its own output onto the shared level set, see Function logs or Object Storage logs.

Use the service name field to narrow the view to one function or bucket. It matches a substring by default; click the ~/= toggle next to it to switch to an exact match on the full name.

Every service reports logs on the same shared level set: DEBUG, INFO, NOTICE, WARN, ERROR, FATAL. Not every service emits every level. See the service-specific pages linked above for what each one actually produces.

Use the level chips to show only the levels you care about, and the search box to match a literal, case-insensitive substring in the log body. Use the time-range chips (5m, 15m, 1h, 6h, 24h, 7d) to change the query window. Logs are retained for only 3 days (see Retention), so the 7d option is selectable but can't return anything older than 3 days back.

If a query matches more than 1,000 lines, the view shows only the most recent 1,000 and displays a banner telling you to narrow the time range or add a search to see the rest.

If no logs match the current filters, the empty state offers a Widen time range button that expands the query window in one click.

Go live polls for new log lines every 5 seconds; it isn't a push-based live tail. Toggle it off to stop polling and inspect a static view.

Download saves the log lines currently loaded in the view, exactly as filtered, to a plain-text .log file, newest first. Downloading doesn't re-run the query against the full retention window: it's a snapshot of what's on screen, so narrow your search, levels, and time range first if you want a smaller or more targeted file.

The same branch logs are available from the terminal with neon logs query, so you can filter and script against them without opening the Console:

Bash
neon logs query --since 30m

Combine filters like --source, --service-name, and --severity-text, or pass a raw --logql expression.

Logs are retained for 3 days. Once a log line falls outside that window, it's no longer queryable in the Console.
