Resolution

The issue is resolved in SolarWinds Platform 2025.4. Consider upgrading your environment. If you cannot upgrade, use the workaround below.

Go to and open 'C:\Program Files\SolarWinds\Orion\NetPerfMon.Charts' using Notepad or NotePad++
Replace

with

Cast(Cast(DateTime as DateTime) as float)

3. Do step 2 for 'C:\Program Files\SolarWinds\Orion\NPM-NetPerfMon.Charts' as well
4. Restart Orion services
