System

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.

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.

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)
