23.1.2 System Supervision
Unite CM can supervise the modules that respond to a survey request. A request will be sent
to the module with the specified interval, default set to 30 seconds. Unite CM can send a
supervision request (either to a Unite module or an ICMP ping) every second, i.e. if the
interval is set to 30 seconds up to 30 modules (Unite or IP Equipment) can be supervised. If
this limit is exceeded, the interval will automatically be increased.
In the response, the module includes information about host name, software version,
module key, license, start-up time and start-up cause. If the error relay is released, the
response will include this information also which will result in the status “Error” in the
overview.
If the module does not answer on the request, Unite CM will generate a persistent Status
Log. It includes the module type, IP address and host name of the non-responding module.
The default level is “Critical”, but can be changed on the setup page. It is also possible to add
a customized text to the Status Log. The persistent fault will be cleared when Unite CM gets
a response from the module.
When supervision is started/ended and when the supervision interval is changed, an
Activity Log with information about the changes will be sent.
Change the Supervision Settings
On the Setup page, it is possible to choose if a module should be supervised or not and to set
the interval (in seconds, default value is 30 seconds) at which Unite CM sends out a module
status request to the supervised module. The fault level, event description and interface
description can be edited from this page. There is also a direct link to the supervised
module’s Advanced Configuration page for basic configuration of the module.
Note that changing settings is only possible for supervised modules in the Existing Modules
list. Refer to 23.1.1 System Survey on page 157 for more information.
1 Click “Configuration” on the start page.
2 Select Supervision > Unite Modules in the menu on the Configuration page.
New modules in the system are found in a New Modules list and can be added to
Existing Modules list by pressing “Add”.
