FTP Monitor
The FTP Monitor checks whether your FTP service is reachable and responsive. This helps detect outages on file transfer infrastructure used by legacy integrations, batch exports, or partner uploads.
How it works
- We connect to your FTP endpoint and verify that the service responds.
- If the server cannot be reached or does not respond within the configured timeout, the check fails.
Configuration
Basic settings
- Hostname: Hostname only, without protocol or path.
- Port: Optional (default is typically 21).
- Check interval and Timeout.
- Status:
active,maintenance,disabled.
Advanced settings
If your server requires authentication or encryption (e.g. FTPS), advanced options can be configured via the monitor settings.
Monitoring locations
FTP checks run from our monitoring locations. Monitor-level Allowed Check Countries (or customer-level defaults) control which locations are used.
Port-only mode (no credentials)
By default (Check Mode: protocol), the monitor connects to your FTP endpoint and verifies that the service responds as expected. Set Check Mode to tcp to skip that protocol validation. The monitor only opens a bare TCP connection to hostname:port, without any FTP handshake, and no credentials are required or stored. Use tcp mode when you only need to confirm the port is reachable.
TCP Port Monitor
The TCP Port Monitor checks whether a raw TCP port is open and accepting connections. It is commonly used for databases, caches, message queues, and other non-HTTP services that don't speak a protocol we have a dedicated monitor for.
IMAP/POP Monitor
The IMAP/POP Monitor verifies that your mail server is reachable for clients. This is useful for detecting authentication and connectivity issues that impact inbox access.
