This hotfix is cumulative with SolarWinds NPM 11.5.2 Hotfix 2 and SolarWinds NPM 11.5.2 Hotfix 3.

SolarWinds Network Performance Monitor version 11.5.2 Hotfix 4
==============================================================

This hotfix addresses the following issues:
- Data polled using the Multicast Routing poller are associated with incorrect timestamps. Instead of the time when the data were polled, the current time is recorded.
- Multicast Routing poller returns 0 for incoming bits per second but values greater than 0 for incoming packets per second. This is because counters for PPS and BPS are calculated as 0.
- Multi-cast data are not processed and recorded. When polling multicast data, you might see the following error in the DataProcessor.log:
System.Exception: Error in PrepareParameters:
parameterName: SourcePps
parameterType: Single
parameterValue: 0
Original error:
Arithmetic operation resulted in an overflow.
- Incorrect SSID is displayed for Ruckus wireless clients.

Install the hotfix on all polling engines affected by the issue.

SolarWinds Network Performance Monitor version 11.5.2 Hotfix 3
==============================================================

This hotfix addresses the following issues:
* If Database Maintenance starts before midnight, and the maintenance of interface tables is not completed before midnight, you may lose interface statistics.
* When creating a report on interfaces, the Details URL property is not available.
