Event storage from providers in 800xA Multisystem Integration? (MI)
In object Alarm Collection Definition (Library Structure) there is an aspect called Event Attributes. The "Catagory name" (or name from Category translations?) seems to be linked to Storage Classes in the service Event Storage->Special Configuration.
1. Is this correct?
In our MI we have Alarm Collection Definitions for each provider system. Seems to be created automatic according to MI-manual 3BSE037076-600 B page 51. The Category Name seems to indicate it comes from the provider system because it has RAC_AE_ProviderSystem added after the each name. And I can't find these Category names in MI service Event storage->Special Configuration->Storage Classes.
2. Is this because these events are not stored in the MI servers? Only in provider systems? And when you take up event list you read it direct from provider system?
3. If this is true, is it correct that all events should be shown in MI? If we increase one event category to 50.000 in all provider systems, we should be able to see all 50.000 from each provider in MI, not just max 50.000 total from all systems?
4. 50.000 seems to be a max limit in provider system. But if above is true we can see 250.000 events (if we have 5 providers) in MI? (But with different "end-date" from each system).
- provider alarms are copied and remapped to new categories in the subscriber.
- provider events remain in provider and are read on-demand by event lists in subscriber
- increasing Event Storage in a provider system will also make those additional events available to a subscriber.
- the Alarm Manager in a subscriber will have more to handle since all alarms are copied there from all providers. Care must be taken to avoid alarm flooding. Unnecessary categories should be zeroed and less important (e.g. system alarm from providers) should be kept very short to preserve space for process alarms.
The default main alarm storage is 10.000. AFAIK no formal testing has been made with increased values so I would not attempt to increase that figure too much.
Again as I answered in the other thread; its more to it than just number of alarms.
- number of alarm subscribing clients
- depth & size of descendant lists
- number of concurrent alarm filters in use
- number of alarm global and list properties in use
Just to confirm then, it is correct that MI should be able to see a total of latest 250.000 events of each category, if we have set it to 50.000 in each provider system? (but only 50.000 from each system).
I did one thread about alarm and this about events. But since you mention alarms here too I can just ask here instead... About increasing MI Alarm storage to match all provider system I will check if we can make an official support case as you suggested.
One question, you said "provider alarms are copied and remapped to new categories in the subscriber".
Where is the setup that tells what Categorys that are visible in Alarm storage Configuration? Because in MI there are more categorys than in the provider systems. As an example in MI we have an "IT Asset Alarms_RAC_AE_xxx" (for each provider) but we dont have any IT Asset-category in the provider systems Alarm storages. So somewhere you must be able to define what categorys you have? (both regarding provider and subscriber).
