Hi Pradip, The focus of that blueprint is to create metrics from logs in the LogStash component and then publish them to the Kafka metrics topic. The Monasca Threshold Engine can then be used to alarm on the metrics. For example, if the number of errors in a log file exceeds some amount, alarm and send a notification.

Subject: [openstack-dev] [Monasca] Alarm generation from a sequence of events
We come across the following interesting BP in the last weekly meeting: https://blueprints.launchpad.net/monasca/+spec/alarmsonlogs
Understood how the non-periodic nature of log events to be taken care of (by introducing period = -1 in value-meta).
Just wondering can it be possible to use this to satisfy the following usecase:
Given a causal or non-causal sequence of events a, b, c – can we determine that a condition ‘p’ has occurred and alarm on that.
