Extension
- Product information
- Release notes
Overview
This extension leverages the SNMP protocol to provide a complete solution to monitor network infrastructure. The complete configuration is provided out-of-the-box.
This is intended for users, who:
- Would like to monitor health state and performance of their core network infrastructure and provide unified analysis for Ops, DevOps and IT Admins.
This enables you to:
- Monitor health and performance of your network devices
- Set up alerts to be notified by traffic anomalies
Compatibility Requirements
- standard network devices supporting common MIB files
- SNMPv2c and SNMPv3 supported only
Details
This extension is built on top of the new Extension 2.0 Framework.
The extension package contains:
- SNMP DataSource configuration,
- dashboard template,
- Unified Analysis screen template,
- topology definition and entity extraction rules.
More information can be found in the Product News Blog:
Get started
Simply activate the extension in your environment using in-product Hub, provide device configuration and you’re all set up.
