The HSYCO System Monitor I/O Server is used to monitor several key hardware and operating system parameters of an HSYCO server:
- Operating system boot time
- HSYCO start time
- Disk space
- Java memory (used, free and maximum available memory)
- Java total number of file descriptors currently open and number of threads used
- Performance (CPU percent busy time, 1 minute load average, 5 minutes load average)
- Console error messages
- Internet connection status
- Cameras status
- I/O Servers status
- Database update, backup and de-fragmentation times
- Clock drift of remote HSYCO servers monitored through the HSYCOREMOTE I/O server.
It also supports the hardware watchdog if available and supported by the Linux operating system.
Contents
HSYCO Configuration
You can have only one HSYCO System Monitor I/O Server.
Add a SYSTEM I/O Server in the I/O Servers section of the Settings and set its parameters.
Note that the SYSTEM I/O Server doesn't count in the I/O servers license total, so you don't need an extra I/O Server license to use SYSTEM with HSYCO.
High Availability
- Shutdown when inactive: defaults to false.
