This would be a question better posted for follow up on another forum on THWACK like this one Application & Server This is the section of THWACK for Database Performance Analyzer. That said the best bet is to make sure your MIB database is up to date and if the MIB you are searching for is still not there you can submit it for an update to the Solarwinds MIB database. Add MIBs to the SolarWinds MIB database - SolarWinds Worldwide, LLC. Help and Support
Start there and perhaps if you still need help move this discussion to the other section.
