We have Global Monitor and use basic security. We are a 13 hospital system running our QDX environment with 15 sites. Global Monitor allows our operator staff to check the health of interfaces and cycle threads/processes when necessary. The defining of certificates can be a pain but the over-all benefit to our ability to monitor the system overides that.
Please let us know what OS platform, engine version, and global monitor version you run. We may be interested in exploring the global monitor product for our shop.
