Telenor MAM Event Aggregator And Analyzer
About
In the Telenor DMS, the Telenor MAM Event Aggregator and Analyzer element queries an OpenSearch database for aggregated MAM error events offloaded by the system. Aggregations are performed by Device Class Type and Asset ID.
Since the raw data in OpenSearch is retained for only 21 days, the primary purpose of this element is to aggregate and store the data for long-term analysis. It also enables alerting based on error counts.
Aggregated data is stored in two tables:
- Error Events Per Device Type
- Error Events Per Asset ID
These tables support further analysis and reporting.

Data Tables
Aggregated data is displayed on two pages:
Errors Per Device Type, which displays the following information:
Events Count: The total number of errors during the aggregation period, grouped by Error Code and Device Class.
Devices Count: The number of distinct devices that generated errors during the aggregation period.
Errors Per Asset, which shows the Events Count, i.e., the total number of errors during the aggregation period, grouped by Error Code and Asset ID.
