Rob,
Bummer and disappointed! We can't use the automatic geolocation on worldwide maps feature since it is driven off the device SNMP Location field. This feature is unusable for us because we do not populate each and every device with the usable location info to generate long/lat coordinates. We've defined a custom property SiteLocation which has the specific site address. So we would much rather prefer to see this feature be expanded to provide the flexibility to designate a custom property..
Any chance Node property variable support for filtering is provided in this release for Worldwide Map resource (https://thwack.solarwinds.com/ideas/4880)?
