Products

• CA Network Flow Analysis (NetQos / NFA)

Issue/Introduction

After configuring the SNMP service according to the NFA watchdog setup documentation, it is still not functioning. In the watchdog logs we are getting the following error:

System.Net.WebException: The request failed with HTTP status 405: Method Not Allowed.
   at WatchdogMain.DeviceManager.CPUs..ctor(SnmpProfile profile, IPAddress address)
   at WatchdogMain.DeviceManager.WatchDogDeviceManager.Initialize()

Environment

Windows Server

Cause

This issue is due to a misconfiguration of the ProxyService and .NET in IIS.

Resolution

To fix this:

1) Open IIS on the NFA Console server

2) Select 'Applications Pools' on the left

3) Find the ProxyService in the application pools list

4) Double click ProxyService and set it to .NET 4.0 instead of .NET 2.0

5) Hit Recycle on the right had side.

6) Recycle the NetQoS Reporter/Analyzer Watchdog Service
