Watchdog timer is a special embedded function in Remote Files SE that helps keeping up state of the server. While the server is active, watchdog timer monitors it with 1-minute interval. It sends request and check server’s response. If test fails, the server ‘gently’ restarts itself. ‘Gently’ means no active sessions is closed. This is the main difference with restarting the server, when all sessions are closed and users have to login to the server once more to get access to files.

Watchdog timer works automatically. It does not need (and have no) configurable parameters. Due to its small period (1 minute) it can detect and fix server problems in the initial stage when remote users even may not suspect them. Because this function works absolutely automatically, it does not require administrator to take decision, restart, etc. Watchdog timer can sufficiently increase stability of the server.

Watchdog timer monitors both HTTPS/HTTP and FTP (if is used) servers.
