DX NetOps 21.2 network monitoring software continues to innovate and improve the scale, speed, and simplicity of network operations with a focused set of high-value features and capabilities. The latest release of Broadcom’s DX NetOps 21.2 network monitoring software delivers expanded capabilities to monitor and assure your software-defined networking (SDN), and network functions virtualization (NFV) deployments.
DX NetOps can collect and generate events and alarms from any SDN/SD-WAN solution on various network elements in case of failure and changes. Although DX NetOps can display all network events and alarms in a single NetOps portal for network operations center (NOC) teams rather than switching between multiple administrative consoles to monitor both traditional and modern networks, few SDN solutions generate less than 100,000-200,000 alarms/events daily. Due to this, NOC teams have to spend 3-4 hours daily to clear/acknowledge alarms that are not relevant to their business or operations.
A real-world example is one of our European customers migrating all their worldwide data centers to a Software-Defined Data Center (SDDC) architecture. They chose Cisco ACI for this effort. When they first deployed Cisco ACI in one of their data centers, the NOC was flooded with 200,000 tickets into their existing DX NetOps network monitoring software.
After the in-depth analysis, they discovered that out of 200,000 tickets generated by their deployment, only a few of them actually needed their attention. This situation quickly elevated their efforts to rely on network monitoring software, which could reduce this alarm noise while being scalable, reliable, and seamlessly integrated into other third-party solutions.
Figure 1: DX NetOps configuration interface where
teams can blacklist or whitelist events or alarms based on
severity, notification id, fault code, type or other factors in order to reduce alarm noise and improve triage times.
DX NetOps network monitoring software introduces a new filter mechanism with a global configuration to filter network alarms and events for all SDN/SD-WAN solutions, and it can be configured from the DX NetOps user interface. This new feature will allow customers to define the filters based on the Event ID, Event Types, Fault Code, Severity, and other feasible options based on the vendor technology.
Customers can then decide whether they want to blacklist or whitelist certain types of events and alarms or create actionable events or alarms. Here are some advantages to having this new capability:
- Filtered alarms will get removed automatically from DX NetOps with no additional steps needed.
- Single configuration for all the DX NetOps plugins with easily defined global filters for the common conditions/parameters.
- Restart of services like engine/wildfly not required for any change in filter configuration such as Create/Update/Delete operations.
- Support whitelisting and blacklisting of Events and Alarms.
- Define distinct filters for each site/technology or single filter for all running engines.
