Before we get started down the road of troubleshooting, it is important to ensure we are all speaking the same language when specific terminology is used throughout this document.

Description |
|---|---|
|
Adapter |
Adapters are how VCF Operations communicates with other products within the environment. For instance, when utilizing the Everpure Management Pack you will configure a separate adapter for each FlashArray you wish to monitor with VCF Operations. |
|
Analytics Nodes |
Analytics nodes consist of the master node and data nodes (if used). |
|
Master Node |
The initial, required node in all VCF Operations Manager deployments. All other nodes are managed by the master node. In a single-node installation, the master node manages itself, has adapters installed on it, and performs all data collection and analysis. |
|
Management Pack |
A management pack is (often) a third-party solution you install to integrate with various other products within the environment. Management packs can contain dashboards, alerts definitions, reports and the adapters needed to communicate with their respective products for VCF Operations integration. |
|
Remote Collector Node |
Remote collector nodes gather data but leave the storage and processing of the data to the analytics cluster. |
|
Replica Node |
To use VCF Operations high availability (HA), the cluster requires that you convert a data node into a replica of the master node. |
|
Witness Node |
To use VCF Operations continuous availability (CA), the cluster requires that you have a witness node. If the network connection between the two fault domains is lost, the witness node acts as a decision maker regarding the availability of VCF Operations. |
