When viewing the timeline, you'll note that PCs can return different statuses. These status codes translate as follows:
- 299 - Alert Sent. (Not acknowledged / Display not started) - This could mean the PC is not online, client app is no longer installed, or just hasn’t polled the server yet.
- 400 - Alert Start / Displaying. The message is displaying on the PC.
- 401 - User Acknowledged. The message was dismissed by a user. (Acknowledged)
- 402 - Alert Expired. The message displayed until expired. (Not acknowledged)
- 403 - Alert Canceled. The message was canceled in the admin console and thus display ended.
- 404 - Alert Replaced. The message was replaced by another message sent to that PC.
- 405 - Message Unread. The message was never picked up by this desktop and the message has since expired. (Never displayed the message.)
What can cause a desktop's status to remain as "unread" (and not receive desktop alerts)?
There are several causes that can prevent a computer from receiving desktop alerts:
- The PC is offline, "asleep", or disconnected from the web.
- The PC is not running the Omnilert Desktop Alert (ODA) client.
- The PC has uninstalled the ODA client.
- The PC is behind a network firewall or proxy that prevents the ODA client from reaching out to Omnilert.
- The user profile logged into the PC has disabled or blocked ODA from connecting. (Personal firewall)
A large number of "Message Unread" responses in the logs can indicate a network issue blocking PCs from reaching desktop.omnilert.net to receive alerts.
