10 System Supervision and Security
10.1 System Supervision
10.1.1 Unite System Supervision
The UPAC 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. The UPAC can
send a supervision request (either to a Unite module or an ICMP ping) every 2 seconds, i.e.
if the interval is set to 30 seconds up to 15 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 and OS
versions, module key, licence, 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.
Status Symbols
If the module does not answer on the request, the UPAC 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 the UPAC 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 the module should be supervised or not, and
to set the interval (in seconds, default value is 30 seconds) at which the UPAC 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
administration pages for basic configuration of the module.
