Please, Dojo
looking for some kind of confirmation about the search behaviour in DataMiner
(10.2, Cassandra based, no Elasticsearch, no Cassandra Cluster, Multiple DMAs in cluster)
A couple of questions..
1) When Opening the "Element>Alarms" page (e.g. in the Microsoft protocol)
and selecting "Last24h", is this the same as dragging the element in Alarm Console
and selecting the same time span?
In other words, is the search mechanism the same across A & B here below?
The element can be hosted on a different DMA from the one where CUBE is connected - but in the case of the example above, I have it on the same DMA - yet the last 24h search seems very slow.
2) On average, in a system that is performing well,
what's the expected time to retrieve the last 24h alarms for a single element?
I think this depends heavily on the number of alarms logged - but when looking for "Alarms" in the local DB, are "Info Events" for the element still part of what the server needs to parse? Or I can have thousands & thousands of info events per day without impacting the search behaviour for the alarms in the last 24h ?
Thanks
Hi Alberto,
- Loading the history alarms in the elementcard or loading the history alarms by dropping an element on the alarmconsole uses the same mechanism to load the alarms and will result in the same set of alarms.
- The time to load the alarms of the last 24h depends on the amount of alarms in the database. The number of information events should not influence the loading of the alarms (unless you load these as well) as these are stored in another table.
