Please install the November 2020 firmware update on your Didactum measurement and remote control system. In the German web interface, under "Logical Scheme," you will find a new menu item at the top: "Activation/Deactivation of the Logical Scheme." Here, all rules and automatic actions will be deactivated for a specific period (selectable from 10 minutes up to a maximum of 24 hours).
IMPORTANT: Please note that this is a general/global function that will disable all notification and alarm functions of your server room monitoring system for a specific period! We strongly advise against deactivating the alarm function of any smoke detectors, voltage detectors, or water detectors installed in the server room! Of course, you can also deactivate previously created monitoring functions and their associated alarm notifications (access control, door contacts, vibration sensor, motion detector, automatic video transmission, etc.) individually.
We assume that you have configured individual threshold and alarm values for the SNMP-compatible temperature sensor in your smart monitoring system. For example, you may have defined a temperature value of 24.5 degrees Celsius as the threshold between the sensor states "Normal" and "Warning." If the temperature falls just below 24.5°C, the temperature sensor is considered to be in "Normal" mode. If the current temperature reaches a value just above 24.5°C, the status "Warning" is displayed. In practice, the measurement data often fluctuates between the previously defined threshold values of "Normal" and "Warning." In such a case, you would receive too many notifications and alarm messages from the smart measurement and monitoring system.
The solution:
Simply use the hysteresis function offered by the monitoring system. Using the "Time" hysteresis type, you can define, for example, the required duration for the state change from "Normal" to "Warning" (and vice versa). You can, for instance, set a time duration of 1 minute before the monitoring system reports the new state as "Normal" or "Warning." If you use the "Value" hysteresis type, the current sensor status will not be reported unless the temperature fluctuates by a larger (measured) value than previously defined in the monitoring system.
Please only access the HTML5-based web interface of the monitoring devices using Google Chrome, Apple Safari, or Mozilla Firefox. Please also check if the recommended Java plugin is installed in your browser. First, try deleting the rule created under "Logical Scheme" using the web browser that is not authorized for this purpose. You may need to restart the IT monitoring device beforehand. If the rule cannot be deleted, please perform a factory reset using the DIP switches or use the CPU tool included in the firmware file.
After the monitoring system has been reset to its factory default settings, please use only Chrome, Safari, or Firefox for configuration. Your monitoring system should then function correctly as usual.
Currently, you can define up to 500 different actions and alarms in the Didactum Remote Monitoring System.
After analyzing your configuration file, our technicians determined that you have not defined any rules or automatic actions under "Logical Scheme" in the web interface. These logic rules must be defined so that your network thermometer can notify and alert you and your colleagues in the event of a critical temperature in the server room. Instructions on how to define notifications and alarms are available here.
You can deactivate the notification and alarm rules stored in the web interface of the Didactum measurement and monitoring systems with a single click. To do this, go to the "Logical Scheme" menu item. Here you can a) deactivate all rules or b) deactivate individual rules for a specific period. In your case, select your alarm rule "Server Cabinet Door Contact".
Under "Deactivate Scheme", select "Yes". Then define the deactivation period. The IT monitoring device offers options such as 10 minutes or several hours. Click "Apply". The deactivated alarm rule will now be displayed in red. After the specified period expires, the rule will be automatically reactivated.
