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
- 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.
Options
| ID | Default | Values | Description |
|---|---|---|---|
| gui | true | true | enable support for the UI object, UISET actions and USER commands |
| false | disable UI support | ||
| internetmonitor | true | true | enable internet connection check |
| false | disable internet connection check | ||
| pollinterval | 30 | n ≥ 10 | the data acquisition interval, in seconds |

User Interface
Hsycomonitor Object
A panel that monitors the system. These parameters are displayed:
- system boot time
- HSYCO start time
- disk free space
- memory in MBs: used, free, max
- CPU usage in %: busy, load 1m, load 5m
- faults: console, internet, cameras, I/O servers
- error messages
Parameters
- server ID: the ID of the server as specified in hsyco.ini
- label: the text label on the panel. Can contain HTML tags
- position: the object's position. Use the pixels or rows and columns coordinates format
Syntax
(hsycomonitor <server ID>; <label>; <position>)
E.g.
(hsycomonitor system; System; x10y20)
