+ | ==== Hardware recovery unit ==== | ||
+ | |||
+ | station-supervisor daemon running on station computer should use external support device for error outputs. | ||
+ | Connection management will be self controlled in device. Interface | ||
+ | between hardware recovery unit and main station computer should be | ||
+ | terminal based. | ||
+ | station-supervisor monitor software (if it is running, otherwise by | ||
+ | standard system console) in system console mode station | ||
+ | supervisor-should write debug output on this device (similarly to dmesg | ||
+ | for example) | ||
+ | |||
+ | Technically the link between main computer and hardware recovery unit is implemented on RS232 serial interface. | ||
+ | |||
+ | ==== Web monitoring interface ==== | ||
+ | |||
+ | Web access is primary diagnostic interface. Terminal is secondary as | ||
+ | backup. | ||
+ | |||
+ | Moreover web access is intended as file based. File based means that | ||
+ | station-supervisor uploads an diagnostic file to webserver. Webserver | ||
+ | takes this file (probably from more than one station) and serve a web | ||
+ | page with stations status | ||
+ | limited only to modification of an station-supervisor configuration file stored | ||
+ | on webserver. Configuration file may contain an parameter for station reboot | ||
+ | request. After station-supervisor will notice change or update in the | ||
+ | webserver stored configuration file, station-supervisor reboots the station and | ||
+ | update its parameters according to actual config file. | ||
+ | |||
+ | This approach is needed, because we usually have not direct IP | ||
+ | connectivity from Internet to stations. | ||
