Network Policy Server (NPS) is the Microsoft implementation of a Remote Authentication Dial-in User Service (RADIUS) server and proxy.
As a RADIUS server, NPS performs centralized authentication and authorization for wireless devices, and it authorizes switch, remote access dial-up, and virtual private network (VPN) connections. Using NPS, you can centrally configure and manage network access authentication, provide authorization for connection requests, and accounting for information logs.
As a RADIUS proxy, NPS allows you to configure connection request policies that tell the NPS which connection requests to forward to other RADIUS servers. You can also configure NPS to forward accounting data to be logged by one or more computers in a remote RADIUS server group.
Applications Manager monitors the availability and performance of Radius servers, and proactively alerts administrators of authentication, authorization, or accounting bottlenecks encountered by the NPS Server.
Are you experiencing sluggish application performance in your Microsoft NPS environment? Monitor the availability and performance of your Microsoft NPS configured as a RADIUS server. You can plan capacity, ensure your host CPU has adequate resources, and monitor your storage memory with CPU and Memory Usage stats. Without impacting application performance, you can add more resources based on server needs.
How quickly your NPS matches connection requests with network policies is a good measure of the efficiency of its policy engine. With Applications Manager, you can measure just that! You will see the length of time taken by NPS to process requests, the rate of pending requests on NPS, and the number of requests that matched configured policies. With this approach, Applications Manager exposes processing bottlenecks on the NPS and how they impact policy matching.
The NPS also provides a central accounting recording service for all accounting requests sent by the clients. The accounting request and response measures serve as effective indicators of the workload on the NPS server. Accounting data can also assist with network access troubleshooting. With Applications Manager, you can easily track accounting requests and responses between NPS and clients; uncover the load on a server to pinpoint irregularities in load balancing; proactively detect potential slowdowns, accurately isolate what is causing it, and promptly fix the problem. Additionally, you can capture the rate at which packets are dropped, as well as how many erroneous packets are received by the server; which in turn will shed light on any issues with the client, or in the network connection between the server and the client.
When NPS is used as a RADIUS server, it provides a central authentication and authorization service for all access requests that are sent by RADIUS clients, and it authenticates user credentials for connection attempts. As a RADIUS proxy, NPS is a central switching or routing point through which RADIUS access and accounting messages flow.
Using Applications Manager, you can be instantly notified if your NPS frequently defies access requests or rejects requests very often. You can also rapidly capture any unusual delays in request authentication by NPS; track the Access-Request messages sent by every access server for authentication, and report the rate at which these access requests are challenged or rejected by NPS.
Applications Manager helps you distinguish consistent performance patterns from anomalies, which is critical to ensuring that your data platform delivers optimal performance for the end users of your applications. Additionally, you will be alerted if there are potential slowdowns in NPS authentication, and you'll be able to spot any abnormal number of rejections of access requests, as well as authentication bottlenecks. By receiving instant notifications of performance issues and bottlenecks, you can take quick remedial action before your end users experience issues.
With Applications Manager, you gain system-wide visibility into resource utilization, application performance, and operational health of your NPS and application performance. Quickly begin NPS Monitoring with Applications Manager’s full-fledged, 30-day free trial edition.
