Network Performance Monitor for network visibility across clouds. As you manage your cloud applications, it is also important to have visibility into the virtual network connections between datacenters, remote office sites, and critical workloads. Network Performance Monitor (NPM), a cloud-aware network monitoring solution in Operations Management Suite Insight & Analytics, that monitors networks for performance degradation and outages.
New features and enhancements have been added to the Network Performance Monitor solution to aid in comprehensive monitoring and faster troubleshooting:
- ICMP based reachability tests: NPM can detect connectivity using Internet Control Message Protocol (ICMP), in addition to TCP. ICMP-based probing is used in environments with restrictive firewall configurations, that prevent routers, switches, and hosts from responding to TCP based probes. This post provides guidance on selection of the right protocol for your environment.
- Network State Recorder: Enhancements to NPM, enable the admin to view the state of the network at any point in the past. To investigate a network connectivity incident, that a user may have encountered last Friday night – select the date and time and NPM presents the connectivity, loss, and latency status at that instant.
- Topology Map: This map presents all the network paths between the endpoints and helps localize a network problem to a particular path. You can drill down into the node links and visualize the hop-by-hop topology of routes. The topology map is now interactive, enabling the filtering of paths by health status (e.g. paths with a high loss), addition/removal of network hops, zoom, and more.
Improved Alert Management: NPM now leverages the alert management capabilities in OMS. Users can now get email-based alerts, in addition to the existing alerts within NPM. Alerts can also be used to trigger remedial actions via runbooks or integrate with existing service management solutions using webhooks.
Windows desktop support: NPM agents can now run on Windows desktops/client operating systems (Windows 10, Windows 8.1, Windows 8, and Windows 7), in addition to the previously supported Windows Server OS.
- Linux support: NPM agents can now test network connectivity from Linux workstations and servers. The following distributions are supported: CentOS Linux 7, Red Hat Enterprise Linux 7.2, Ubuntu 14.04 LTS, Ubuntu 15.04, Ubuntu 16.04 LTS, Debian 8, and SUSE Linux Server 12.
- Search: Improvements in search, enable quicker drill-down to the specific network and subnets that may be faulty, thereby enabling faster identification and remediation.
