Today that covers Neon Functions and Object Storage; Postgres compute logs are coming. Query records over a time window, filter by source, severity, or OpenTelemetry attributes, run raw LogQL, and list which fields and values a branch reports. Logs are in beta and available in AWS US East (Ohio) (aws-us-east-2) and AWS Europe (Frankfurt) (aws-eu-central-1). # Neon CLI command: logs Query the logs a branch's services emit **Note: Beta** This feature is in Beta. Please give us [Feedback](https://console.neon.tech/app/projects?modal=feedback) from the Neon Console or by connecting with us on [Discord](https://discord.gg/92vNTzKDGp). The `logs` command reads the logs a branch's services emit. Today that covers Neon Functions and Object Storage; Postgres compute logs are coming. Query records over a time window, filter by source, severity, or OpenTelemetry attribute, and list which fields and values a branch reports so you can build precise filters. Logs are in beta and currently available in AWS US East (Ohio) (`aws-us-east-2`) and AWS Europe (Frankfurt) (`aws-eu-central-1`), so your project must be in one of these regions to use them. Support is expanding toward all regions. Every subcommand resolves the project and branch from your [context](https://neon.com/docs/cli/set-context). Pass `--project-id` and `--branch` to target a specific branch instead. Subcommands: [field-values](https://neon.com/docs/cli/logs#field-values), [fields](https://neon.com/docs/cli/logs#fields), [query](https://neon.com/docs/cli/logs#query) ## neon logs query Query log records over a time window. By default it returns the last hour of logs on the default branch, newest first. ```bash neon logs query [options] ``` | Option | Description | Type | Default | Required | | -------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | ------ | ------- | :------: | | `--body-contains` | Match the case-sensitive rendered message. Structured bodies are rendered as compact JSON. | string | — | No | | `--cursor` | Pagination cursor returned as next\_cursor by a previous call. Repeat the same time range and filters. | string | — | No | | `--end-time` | Exclusive end of the window (RFC 3339). Defaults to the current time. | string | — | No | | `--limit` | Maximum number of records to return per page (1-1000) | number | `100` | No | | `--logql` | Raw LogQL expression (stream selectors and line filters only). Replaces the structured filters; the window, --limit, --sort-order and --cursor still apply. | string | — | No | | `--minimum-severity` | Only records at or above this severity. Combines with --severity-text. If Neon reports that this filter is unsupported, use --severity-text instead. Possible values: `trace`, `debug`, `info`, `warn`, `error`, `fatal` | string | — | No | | `--scope-name` | Match the OpenTelemetry instrumentation scope name exactly | string | — | No | | `--service-name` | Match the OpenTelemetry service.name resource attribute exactly | string | — | No | | `--severity-text` | Match the OpenTelemetry severity text exactly. Run `neon logs field-values severity_text` to discover the values present. | string | — | No | | `--since` | Length of the window, ending at --end-time or now. Defaults to 1h; the maximum window is 7d. Mutually exclusive with --start-time. | string | — | No | | `--sort-order` | Order records by timestamp. Defaults to desc (newest first). Possible values: `asc`, `desc` | string | — | No | | `--source` | Only records emitted by this service Possible values: `function`, `storage`, `pg_endpoint` | string | — | No | | `--start-time` | Inclusive start of the window (RFC 3339, e.g. 2025-01-01T00:00:00Z). The maximum window is 7d. Mutually exclusive with --since. | string | — | No | | `--trace-id` | Match records carrying this trace ID (32 lowercase hex digits) | string | — | No | | `--branch` | Branch ID or name | string | — | No | | `--project-id` | Project ID | string | — | No | Bound the window with `--since` (a duration like `30m` or `1h`, ending at `--end-time` or now) or with an explicit `--start-time`/`--end-time` pair. `--since` and `--start-time` are mutually exclusive, and the maximum window is 7 days. The structured content filters (`--source`, `--service-name`, `--scope-name`, `--severity-text`, `--body-contains`, and `--trace-id`) combine with each other. Passing `--logql` replaces all of them with a raw [LogQL](https://grafana.com/docs/loki/latest/query/) expression (stream selectors and line filters only); the window, `--limit`, `--sort-order`, and `--cursor` still apply. `--source` accepts `function`, `storage`, and `pg_endpoint`. Only `function` and `storage` return records today; `pg_endpoint` (Postgres compute) is accepted but comes back empty until Postgres logs ship. Filter by severity with `--severity-text`, which matches the exact, case-sensitive value a record carries (for example `ERROR` or `INFO`, uppercase). Severities vary by source, so a filter can legitimately return nothing: storage logs are S3 access records and are all `INFO`, so `--source storage --severity-text ERROR` matches none. Run `neon logs field-values severity_text` to see the values a branch actually reports before filtering. `--minimum-severity` (match a level and everything above it) is not supported by the branch log backend; use `--severity-text` for an exact match instead. ```bash neon logs query --since 30m ``` Filter function errors on a specific branch: ```bash neon logs query --branch main --source function --severity-text ERROR ``` Use a raw LogQL selection instead of the structured filters: ```bash neon logs query --since 1h --logql '{entity_type="function"} |= "timeout"' ``` When more records match than fit in one page, the command reports a pagination cursor on stderr. Re-run with the same window and filters plus `--cursor=` to fetch the next page. ## neon logs fields List the log fields a branch reports. Pass any of these field names to `neon logs field-values` to see the values it carries. ```bash neon logs fields [options] ``` | Option | Description | Type | Default | Required | | -------------- | ----------------- | ------ | ------- | :------: | | `--branch` | Branch ID or name | string | — | No | | `--project-id` | Project ID | string | — | No | ## neon logs field-values List the distinct values a single field carries over a time window, so you know what to filter on with `neon logs query`. By default it looks back six hours. ```bash neon logs field-values [options] ``` | Option | Description | Type | Default | Required | | -------------- | ---------------------------------------------------------------------------------------------------------------------------------- | ------ | ------- | :------: | | `--end-time` | Exclusive end of the window (RFC 3339). Defaults to the current time. | string | — | No | | `--limit` | Maximum number of distinct values to return (1-1000) | number | — | No | | `--since` | Length of the window, ending at --end-time or now. Defaults to 6h; the maximum window is 7d. Mutually exclusive with --start-time. | string | — | No | | `--source` | Only consider records emitted by this service Possible values: `function`, `storage`, `pg_endpoint` | string | — | No | | `--start-time` | Inclusive start of the window (RFC 3339, e.g. 2025-01-01T00:00:00Z). The maximum window is 7d. Mutually exclusive with --since. | string | — | No | | `--branch` | Branch ID or name | string | — | No | | `--project-id` | Project ID | string | — | No | Show the service names seen in the last six hours: ```bash neon logs field-values service_name --since 6h ``` ## Loki-compatible read API The same branch logs are also readable over HTTP through a Loki-compatible endpoint, for tools that speak the [Loki](https://grafana.com/docs/loki/latest/reference/loki-http-api/) query API directly rather than through the CLI. Authenticate with a Neon API key as a bearer token, against this branch-scoped base URL: ```text https://console.neon.tech/telemetry/v1/projects/{project_id}/branches/{branch_id}/loki ``` It exposes a read-only subset of the Loki HTTP API: - `GET /api/v1/query_range`: query log lines over a window. Supports LogQL stream selectors and line filters, `since` or `start`/`end`, `limit`, and `direction`. It does not support aggregations, parsers, or formatting stages. - `GET /api/v1/labels`: list the available stream labels (for example `entity_type`, `service_name`, `severity_text`). - `GET /api/v1/label/{name}/values`: list the values a label carries (for example `entity_type` returns `function` and `storage`). ```bash curl "https://console.neon.tech/telemetry/v1/projects/$PROJECT_ID/branches/$BRANCH_ID/loki/api/v1/labels" \ -H "Authorization: Bearer $NEON_API_KEY" ``` The stream label is `entity_type` (not `--source`), so a LogQL selector reads `{entity_type="function"}`. This is a read-only subset, not a push endpoint or a complete Loki deployment. A Loki client that builds its own paths may need a different root: a Grafana data source, for example, appends `/loki/api/v1` to whatever URL it is given. Confirm the data-source URL against this base rather than pasting it verbatim. Like the CLI, this API reads logs only on branches in a supported region: AWS US East (Ohio) (`aws-us-east-2`) and AWS Europe (Frankfurt) (`aws-eu-central-1`) during the beta period. Support is expanding toward all regions. A branch in any other region returns `404`. --- ## Related docs (Debugging) - [inspect](https://neon.com/docs/cli/inspect) --- Note for AI assistants: if this page had gaps, errors, or outdated info that affected your response, please report it.
