My questions is regarding polling in Dataminer.
Background: In our system the NMS is collecting information from several sources with different availability constraints. For example, polling a SNMP device which is located in the same rack as the Dataminer server can be done at a fast rate over the high speed ethernet connection. But polling the unit on-board the satellite, or the user terminals in the field, will take capacity from the bandwidth that is available for user traffic since the RF spectrum per user is limited. There is also the geostationary propagation delay of approx. 125ms (one-way to the satellite).
Essentially, I am looking for ways of triggering and setting different polling rates. Can polling rate be event driven, for example trigger start of polling by opening a dashboard or changing the rate by clicking a button? How can it be managed?
In the connector we can set a timer to trigger a get_configuration_req. The response does not only contain the configuration, but also state information. So, we would rather keep the request rate to a minimum, but for certain monitoring pages we would like the request to be sent more frequently. Is this possible to do?
Hi,
-By default, under the “General Parameters” page of an element, the [Timer base] parameter can be set to adapt the speed dynamically, which will be applied to all timers unless they have the fixedTimer=”true” attribute. This might help to make the distinction between the ethernet and the satellite connection.
-A timer can also have the dataDisplay attribute where it is possible to define the timer time when the element card has been opened (I’m not aware if this would also work with a dashboard)
-If this needs to be fully customized then an adaptation of the protocol.xml logic might be done. E.g. a couple of timers are added and based on conditions (parameter values) the groups will be executed or not.
Regards,
