I have a group of servers that are synchronized via NTP. One server is running an NTP server and I was able to install the SNTP/NTP sensor to monitor it. The other servers in this group use NTP clients to sync to the server running the NTP server but I can't figure out a way to add sensors to confirm the clients are staying in sync. Normally this shouldn't be an issue but we've had cases where the NTP clients have been set to the wrong IP address or the IP address has changed so even though the NTP clients are running, the time isn't staying in sync. It would be great if there was a simple way for PRTG to check this (without resorting to a custom VBScript). Any suggestions?
