Interfaces with High Percent Utilization Resource Fails Method System ConvertToInt32 Double value fail to convert the received value to Int32

Updated: August 15, 2016

Overview

This article describes the issue when the Web Console stops loading the high percent interfaces utilization resource.

 

 The following errors appear:

ERROR SolarWinds.Orion.Web.UI.BaseResourceControl - Exception while loading resource

Method "System.Convert.ToInt32(Double value) faill to convert the received value to Int32"


Environment

  • All versions of NPM
  • All versions of SAM 

Cause 

In this case, the issue was the device was sending unrealistic high numbers via WMI and caused exception in the resource.

 

Resolution

Check the interface tables. In this case, WMI node had interfaces with percent utilization like 24575890000%.

It's because the device reports bandwidth=0 and the traffic is like 2.457589E+17. If the device is not able to report correct bandwidth, set the custom bandwidth on Interface Edit web page.
