Alarm enrichment, bulk size

  • 1.  Alarm enrichment, bulk size

    I'm trying out the overwrite-rules in the nas probe but it don't quite work out for me. The log tells me:


    [main, alarm_enrichment] AlarmQueueReader: bulk_read_size must be less than than MAX_HUB_BULK_SIZE: 100 


    bulk_read_size in the nas raw configuration is set to 250, where can I change the MAX_HUB_BULK_SIZE? (if this is even the problem )

    Good chance the message was already there before making the modifications to nas config. Not sure if it is really a problem or not. The message is in regards to the bulk size for the alarm_enrichment queue which can be set via hub raw configure > postroute > alarm_enrichment. Default of 100 but not set in the config. It can be increased, perhaps to 200 to eliminate the message.

    bulk size is variable based on how much it is actually reading at any given time. If it’s able to read a full 1200 messages successfully, it will continue to take that many in. However, if it cannot then it decreases down to 100. As for the “bulk_read_size” variable, that’s a setting for NAS which never reads in bulk. The key “bulk_read_size” only applies to alarm_enrichment. NAS itself will always read alarms off the bus one at a time.
