When starting Web Monitor and selecting any option under the Event Viewer category, the Web Monitor displays the following message:
"There are no events to display"
Additionally, if you have a UAG Array and you select "Current Status" under the Array Monitor category, you may see that the UAG nodes show a Synchronization Status of "error".
While troubleshooting the issue, the UAG tracing output may show an entry similar to the following:
21FC.2F28::<Date/Time> [MonitorHelper]The dummy request failed: System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it <UAG server internal IP address>:50002
Note: For more information on UAG tracing, please see my teammate Ben Ari’s blog on UAG Tracing:
By default, UAG servers are configured to log UAG related events to the following location:
<UAG install folder>\logs\Events
You can then use Web Monitor to view and filter those logged events. See the following TechNet article for more information related to UAG logging:
By default, both the LOGS folder and EVENTS folder have the following Security Permissions:
SYSTEM - Full Control
NETWORK SERVICE - Full Control
Administrators (<localserver>\Administrators) - Full Control
Users (<localserver>\Users) - Read & execute, List folder contents and Read
You may see the above Web Monitor errors if the NETWORK SERVICE does not have the proper permissions for the Logs and/or Events folders.
Make sure that the NETWORK SERVICE has Full Control permissions for the Logs and/or Events folders (including subfolders and files).
