The operations management design includes components such as vRealize Operations Manager and vRealize Log Insight that form the operations management layer in the Telco Cloud Platform RAN solution. This section provides guidance on the main design elements such as sizing, networking, and diagnostics.

Note:

vRealize Operations Manager and vRealize Log Insight are optional components for Telco Cloud Platform RAN.

vRealize Log Insight Design

The vRealize Log Insight cluster consists of one primary node and two worker nodes behind a load balancer. The vRealize Log Insight Cluster is located in the management cluster at Regional Data Center, and all logging traffic is sent across the site-to-site link.

Enable the Integrated Load Balancer (ILB) on the three-node cluster so that all log sources can address the cluster by its ILB. By using the ILB, you do not need to reconfigure log sources with a new destination address in case of a scale-out or node failure. The ILB also guarantees that vRealize Log Insight accepts all incoming ingestion traffic.

The ILB address is required for users to connect to vRealize Log Insight using either the Web UI or API. It is also required for clients to ingest logs using syslog or the Ingestion API. A vRealize Log Insight cluster can scale out to 12 nodes: 1 primary and 11 worker nodes.

Table 1. Recommended vRealize Log Insight Design

Design Recommendation

Design Justification

Design Implication

Configure the enterprise edge sites to forward syslog data to the Centralized vRealize Log Insight Cluster.

Provides a central logging infrastructure for all Cell Sites.

All logging traffic is sent over the site-to-site link.

vRealize Operations Manager Design

The vRealize Operations Manager deployment is a single instance of a 3-node analytics cluster that is deployed in the management cluster along with a two-node remote collector group.

The remote collectors collect data from the compute vCenter Servers in the management cluster. Deploying remote collectors into enterprise edge sites would generate unnecessary traffic and occupy compute resources.

Table 2. Recommended vRealize Operations Manager Design

Design Recommendation

Design Justification

Design Implication

Configure vRealize Operations Manager to collect metrics from the compute vCenter Server

Provides operations management infrastructure for all Cell Sites.

As the Cell Sites are added, more data nodes and remote collectors need to be added.
