ContributionsMost RecentMost LikesSolutionsRe: DataSources_List PropertySource @Antony HawkinsFirst, I would like to say that this PropertySource is awesome and solved a big problem I had on trying to manage SDT for some SQL Queries we added as DataSources. I do have an issue that I hope you can help with. The PropertySource has been added to our environment and it is working great on every device that isn't monitored by a Large Collector. The devices monitored by these collectors test well in the PropertySource and fall into the AppliesTo devices, but the property is never written to them. If I change a device from being monitored by a Large Collector to a Medium Collector then the property is written. Any ideas what may be causing this and how to resolve?
