Product Architecture

DX NetOps Performance Management
uses an extensible multiserver architecture to support monitoring the largest networks.
DX NetOps Performance Management
uses an extensible multiserver architecture to support monitoring the largest networks. It provides more information about your network by collecting performance data and integrating with other data sources, such as
CA Application Delivery Analysis
and
Network Flow Analysis
. This article covers the basic system architecture.
The following diagram shows the basic system architecture:

For
DX NetOps Performance Management
to work properly in a firewall-protected environment, certain ports must be open.
For more information about these ports, see Review Installation Requirements and Considerations.
Components
DX NetOps Performance Management
includes the following primary components:
  • NetOps Portal
    • Front-end client for the console, dashboards, and reporting
    • Administration and event management
    • Integrates with other data sources
  • Data Aggregator
    • Data loading and normalization
    • Threshold monitoring
    • OpenAPI
  • Data Repository
    • Vertica database for data aggregator performance data
    • Multi-node (3-5) cluster for large networks
    • Single node for small networks
  • Data Collector
    • Simple Network Management Protocol (SNMP) and Internet Control Message Protocol (ICMP) discovery and data collection
    • Integration point for
      DX NetOps Virtual Network Assurance
      and
      DX NetOps Mediation Manager
    • Each supports monitoring up to 500,000 monitored items
    • Multiple data collectors support large or geographically dispersed networks
  • DX NetOps Mediation Manager
    • Collects non-SNMP inventory and performance data
    • Loads data to the data aggregator through a dedicated data collector
  • DX NetOps Virtual Network Assurance
    • Collects inventory and performance data from software-defined networking (SDN) and network functions virtualization (NFV) environments
    • Loads data to the data aggregator through a data collector
Other Architectures
The following architectures reduce data loss:
  • Disaster Recovery
    If a large-scale disaster occurs, disaster recovery enables a switchover to a recovery system.
    For more information about disaster recovery, see Disaster Recovery.
  • Fault Tolerance
    Fault tolerance enables your
    DX NetOps Performance Management
    environment to continue operating properly when a hardware failure or network issue occurs.
    For more information about fault tolerance, see Fault Tolerance.
A low-scale architecture is also available. A low-scale architecture matches the basic architecture, but the data aggregator and data Collector are on a single node. If the sizing tool indicates a low-scale deployment, see Install a Low-Scale System.
