Hi,
what is the right procedure to delete all actual history alarms?
Go into DevCenter and "TRUNCATE alarm;"
Use nodetool to delete snapshots?
nodetool clearsnapshot

Hi Dominik,
Indeed, when using Clustered Databases, the timetrace table no longer exists in Cassandra. Here, alarms are kept in Elasticsearch.
You can check out which indices you have in elasticsearch by going to
http://[IPADDRESS]:9200/_cat/indices?v&s=index:desc .
This will group your indices together.
Active alarms (which you do not want to remove) are in the [DataMiner prefix]-activalarms index.
All other alarms are in the [DataMiner prefix]-alarms-* index should be historical alarms. It's possible there are a few of these indices. These can be deleted via the Elasticsearch API or, if you're more inclined towards using a UI for this, we can recommend Elasticvue .
Note that this will delete any and all actual history alarms and references to them. It will not be possible to recover them afterwards.
It seems the timetrace table must also be truncated. Is that correct?
