Network Performance Monitor Solution in Operations Management Suite (OMS) [1] monitors network performance in near real-time in terms of network delay and data loss between two Networks, Subnetworks or Nodes which could be physical as well as virtual and could exist across cloud services like Microsoft Azure, Amazon Web Services or even on-premises.
About Operations Management Suite
Operations Management Suite is a Cloud native unified solution for IT management for any enterprise regardless of Location, Operating System used (Microsoft Windows as well as Linux), choice of Hypervisor, choice of Cloud service provider, public cloud, private cloud as well as hybrid scenarios. It helps gain visibility and control of the systems and applications with simplified management and security, cloud integrated backups and easy to manage recovery points to eliminate the chance of data loss in case of disaster and provides a reliable business continuity solution for physical as well as Virtual Machines on-premises and in the cloud.
What Network Performance Monitor does
Network Performance Monitor [2] detects network issues like traffic blackholing, routing errors, Network congestion. It generates a dashboard to display summarized information about the Network including Network health events, unhealthy Network links, and Subnetwork links with most loss and most latency. Custom dashboard can also be generated using OMS features.
An interactive topology map is also generated to show the routes between Nodes. It can be used to distinguish the unhealthy path which is useful for Network administrator to find out the root cause of the issue. Alerts can also be configured to trigger Runbooks to take auto corrective action. [3]
Design
The solution does not require any access to network devices. Microsoft Monitoring Agent (MMA) or OMS extension (valid only for Virtual machines hosted in Azure) is to be installed on one or more servers in the Subnetworks that are to be monitored. The solution automatically detects the Subnet that the Node is connected to.
Network Performance Monitor uses Internet Control Message Protocol (ICMP) or Transmission Control Protocol (TCP) Ping and the roundtrip time for a ping between two nodes is used to calculate network performance metrics such as packet loss and link latency. This data is pushed to OMS where its used to create customizable dashboard. The data can also be used to find the state of the network at a point-in-time in history too.
