PATCH Change collection settings

/api/v1/monitors/{id}/collection

Uses stable source identities. Each changed field is applied in server acceptance order; unrelated fields and measurement history remain intact. Repeat the same operation_id and body after a lost response. Names, descriptions, activation and collection intervals synchronize. Executables and arguments remain in the locally approved policy.

Access and permissions

Uses stable source identities. Each changed field is applied in server acceptance order; unrelated fields and measurement history remain intact. Repeat the same operation_id and body after a lost response. Names, descriptions, activation and collection intervals synchronize. Executables and arguments remain in the locally approved policy.

Browser session: __Host-mb_session cookie.

Machine management credentials in Authorization: Bearer. Check the permissions (scopes) required by the operation.

When using a browser session for a mutation, send the current CSRF token in X-CSRF-Token with the same-site cookie. OAuth consent uses its documented form field.

Parameters and headers

Retries and asynchronous work

This change does not have a general retry guarantee. If the response is unclear, read the affected resource before trying again. Follow Retry-After waiting times and request new sign-in or action codes when they expire.

Request examples

Replace demo IDs, timestamps and placeholders with your own values. For a retry, keep the same IDs, time and content. These examples do not run requests on this page.

Keep login links, codes, cookies and keys private. Do not print them in logs or share them in support requests.

  • HTTP API, OAuth and MCP

    Find the user API endpoints, their permissions, fields, examples and response formats.

  • GET Read collection settings

    Read the current configuration and its agent acknowledgement. The collection interval is separate from the refresh interval of unchanged states. Custom definitions contain only declared field types and source identities, never commands or credentials.

  • POST Preview collection changes

    Uses stable source identities. Each changed field is applied in server acceptance order; unrelated fields and measurement history remain intact. Repeat the same operation_id and body after a lost response. Names, descriptions, activation and collection intervals synchronize. Executables and arguments remain in the locally approved policy.

  • GET Receive collection revisions

    An outgoing HTTPS event stream signals new revisions. Fetch the current snapshot after each event or reconnect; Last-Event-ID is not a replay log. CLI and MCP credentials receive one JSON revision for bounded polling. Without events, poll every five seconds and apply error backoff.
