vRealize Operations Manager tracks and analyzes the operation of multiple data sources in the SDDC by using specialized analytic algorithms. These algorithms help vRealize Operations Manager learn and predict the behavior of every object it monitors. Users access this information by using views, reports, and dashboards.
vRealize Operations Manager is available as a pre-configured virtual appliance in OVF. By using the virtual appliance, you can easily create vRealize Operations Manager nodes with pre-defined identical sizes.
You deploy the OVF file of the virtual appliance once for each node. After node deployment, you access the product to set up cluster nodes according to their role and log in to configure the installation.
You can deploy vRealize Operations Manager as a virtual appliance in one of the following configurations:
Cluster of one master and at least one data node, and optionally a group of remote collector nodes.
You can establish high availability by using an external load balancer.
The compute and storage resources of the vRealize Log Insight instances can scale up as growth demands.
vRealize Operations Manager contains functional elements that collaborate for data analysis and storage, and support creating clusters of nodes with different roles.
Types of Nodes
For high availability and scalability, you can deploy several vRealize Operations Manager instances in a cluster to track, analyze, and predict the operation of monitored systems. Cluster nodes can have either of the following roles.
Required initial node in the cluster. In large-scale environments, manages all other nodes. In small-scale environments, the master node is the single standalone vRealize Operations Manager node.
Master Replica Node
Optional. Enables high availability of the master node.
Optional. Enables scale-out of vRealize Operations Manager in larger environments. Data nodes have adapters installed to perform collection and analysis. Data nodes also host vRealize Operations Manager management packs.
Remote Collector Node
Overcomes data collection issues across the enterprise network, such as limited network performance. You can also use remote collector nodes to offload data collection from the other types of nodes.
Remote collector nodes only gather statistics about inventory objects and forward collected data to the data nodes. Remote collector nodes do not store data or perform analysis.
The master and master replica nodes are data nodes that have extended capabilities.
Types of Node Groups
Tracks, analyzes, and predicts the operation of monitored systems. Consists of a master node, data nodes, and optionally of a master replica node.
Remote Collector Group
Because it consists of remote collector nodes, only collects diagnostics data without storage or analysis. A vRealize Operations Manager deployment can contain several collector groups.
Use collector groups to achieve adapter resiliency in cases where the collector experiences network interruption or becomes unavailable.
Application Functional Components
The functional components of a vRealize Operations Manager instance interact with each other to analyze diagnostics data from the data center and visualize the result in the Web user interface.
The components of vRealize Operations Manager node perform these tasks.
Product/Admin UI and Suite API
The UI server is a Web application that serves as both user and administration interface, and hosts the API for accessing collected statistics.
The Collector collects data from all components in the data center.
The Transaction Locator handles the data flow between the master, master replica, and remote collector nodes.
The Transaction Service is responsible for caching, processing, and retrieving metrics for the analytics process.
The analytics engine creates all associations and correlations between various data sets, handles all super metric calculations, performs all capacity planning functions, and is responsible for triggering alerts.
Common databases store the following types of data that is related to all components of a vRealize Operations Manager deployment:
Collected metric data
User content, metric key mappings, licensing, certificates, telemetry data, and role privileges
Cluster administration data
Alerts and alarms including the root cause, and object historical properties and versions
The replication database stores all resources, such as metadata, relationships, collectors, adapters, collector groups, and relationships between them.
You can configure vRealize Operations Manager user authentication to use one or more of the following authentication sources:
vCenter Single Sign-On
VMware Identity Manager
OpenLDAP via LDAP
Active Directory via LDAP
Management packs contain extensions and third-party integration software. They add dashboards, alert definitions, policies, reports, and other content to the inventory of vRealize Operations Manager. You can learn more details about and download management packs from VMware Solutions Exchange.
You back up each vRealize Operations Manager node using traditional virtual machine backup solutions that are compatible with VMware vSphere Storage APIs – Data Protection (VADP).
Consolidated vRealize Operations Manager Deployment
Because of its scope, VMware Validated Design for Workload and Management Consolidation implements a small-scale vRealize Operations Manager deployment. This implementation is designed to maintain the ability to scale up to the larger VMware Validated Design for Software-Defined Data Center. The validated design uses a load balancer for the analytics cluster that runs on a single node and a one-node remote collector group. By using this configuration, you can scale out the cluster and remote collector group as required while minimizing downtime.
