Setting up statistics and aggregation for Port Throughput on the 7750 SR

Purpose

This use case shows how to use NSP to set up the data collection and aggregation required to run a Port Throughput report in Analytics for 7750 SR NEs managed using MDM.

The following prerequisites must be completed.

  • Telemetry types for port throughput have been installed.

  • At least one 7750 SR NE has been discovered in the network and is reachable.

  • Aggregation rules have been deployed.

Steps
 
1 

From Data Collection and Analysis Management, Subscriptions, we’ll create a subscription.

We need interface utilization statistics for 7750 SR NEs. An object filter that contains “7750” ensures that we receive data whether the NE type says “7750 SR” or “7750 SR-12”.

Let’s look at the aggregation rule for interface data. From the Aggregation view, choose the aggregation rule and click Edit Aggregation Rule to see the details.

The Retention Period fields show how long aggregated data is stored in the auxiliary database. The default retention period for daily aggregation is 90 days. That means that daily granularity is available in Analytics for up to 90 days of data.

3 

Changing the retention period to 120 days makes daily granularity available for a longer time. Change the retention time and click UPDATE.

End of steps

We’re done

We’ve set up a subscription for interface utilization data, and aggregation is deployed. When data has been successfully collected and aggregated, we’ll be able to run a Port Throughput Summary (NSP) report in the Analytics application.
