The IP based Didactum monitoring and alarm systems support the SNMP V1, SNMP V2c and the encrypted SNMP V3 network protocol. SNMP (Simple Network Management Protocol) is an essential part of the worldwide TCP / IP protocol. With the support of SNMP, important performance, status and measurement data can be collected and monitored remotely around the clock. In critical conditions or occurrence of errors, you can be proactively notified and alerted by the Didactum SNMP monitoring hardware. You can also use SNMP to control network-enabled devices and systems.
Each of the SNMPv1/v2c/v3 compatible measurement and monitoring devices also provides automatic notification and alarm functions as part of SNMP Get queries. In addition, actuators, such as relay switching, are also supported by the SNMP monitoring hardware.
To create a SNMP Get element in the IT monitoring system, please go to the "System tree" entry and then click on the "+" icon (top right). A new window called "Add a new element" will open. Select either SNMP Get (analog) or SNMP Get (discrete). How to set up SNMP Get functions in the form of virtual sensors in your SNMP monitoring hardware is shown here.
A capture of videos is supported by the Didactum monitoring systems. This is done via an SNMP set request. To do this, please write the string "1" (without quotes) in the OID identifier .1.3.6.1.4.1.39052.4.1.1.7.403001.
These parameters can be set via SNMP in any SNMP browser. These are standard fields that are generally available for OIDs.
Available are (read and write):
.iso.org.dod.internet.mgmt.mib-2.system.sysContact (.1.3.6.1.2.1.1.4)
.iso.org.dod.internet.mgmt.mib-2.system.sysName (.1.3.6.1.2.1.1.5)
.iso.org.dod.internet.mgmt.mib-2.system.sysLocation (.1.3.6.1.2.1.1.6)
The reference OIDs for the field values remain the same for all Didactum sensors of the same class. A specific sensor is referenced by its ID at the end of the OID.
Please see this example for analog sensors
.1.3.6.1.4.1.46501.1.3.1.5.201001 - here is the sensor class “analog“
.1.3.6.1.4.1.46501.1.3.1.6.201001 - here is the sensor type “temperature“
.1.3.6.1.4.1.46501.1.3.1.7.201001 - name "onboard temperature"
.1.3.6.1.4.1.46501.1.3.1.8.201001 - state "normal"
.1.3.6.1.4.1.46501.1.3.1.9.201001 - current value “35.41“
etc.
Please open the Didactum MIB file in a MIB-browser and you will see it. The sensor ID for those sensors that the user connects or creates may not be sequential (e.g. if a sensor has been removed).
The Didactum MIB file can be found in the English web interface under “Preferences” => SNMP => Download MIB file. Just click on didactum.mib and it will be automatically downloaded from the SNMP monitoring system.
