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)
- 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.
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:
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 |
Datapoints
ID | Value | R/W | Description |
---|---|---|---|

oad.avg.15 | <val> | R | the system’s load average during the last 15 minutes |
disk.free.percent | <val> | R | the free storage space as a percentage of total available space |
disk.free | <val> | R | the free storage space in Mbytes |
disk.used | <val> | R | the used storage space in Mbytes |
disk.errors | <val> | R | only available when the root filesystem is BTRFS, this is the sum of all error counters as returned by the "btrfs devices stats /" command |
memory.free | <val> | R | the amount of free run-time memory of the Java virtual machine, in Mbyte |
memory.max | <val> | R | the maximum amount of run-time memory that could be used by the Java virtual machine, in Mbyte |
memory.used | <val> | R | the amount of run-time memory used by the Java virtual machine, in Mbyte |
camera.total | <val> | R | the total number of cameras defined |
camera.errors | <val> | R | the number of cameras that HSYCO is unable to access |
camera.errors.list | <list> | R | a comma separated list of the cameras having errors, or an empty string if there are no errors |
io.total | <val> | R | the total number of I/O servers defined |
io.errors | <val> | R | the number of I/O servers that HSYCO is unable to access |
io.errors.list | <list> | R | a comma separated list of the I/O servers having errors, or an empty string if there are no errors |

console.errors | 0 | R | the console.log file contains no new errors |
1 | the console.log file contains new errors |
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)
