This article describes how to check server status by reviewing several indicators, including the system tray icon, the Server Details page and Applications page in EMS, and Windows services.
Check Server Status
At the end of the article you should be able to
- Recall the definition of Neverfail Continuity Engine cluster status checking
- Identify the function of each indicator
- Identify four methods to check the server status.
A good maintenance system plan includes regular checks to ensure optimum performance. Neverfail Continuity Engine provides multiple indicators to accomplish this task. Each indicator reports different data related to the status and the overall health of the Continuity Engine cluster.
The System Tray Icon
Right clicking the Continuity Engine system tray icon on any Continuity Engine server reports the identity and role of the server plus the status of data replication. This check however does not provide any further details about replication progress or queue sizes. So you should not rely on this exclusively.
EMS Server Details Page
The Server Details page of the Engine Management Service offers you a more thorough check. It shows the roles in the identities of the servers and the status of the channel and replication. Check to see that only one server is active and that replication is being performed.
EMS Applications Page
The Applications page shows the status of all installed applications. It also shows the start/stop tasks after failover or switchover operation and the output from the monitoring tasks, used to keep file filters correctly configured. Make sure that you see no errors which would be highlighted in red.
Check Windows Services via the Windows Service Control Manager to ensure that the protected application is, in fact, operational on the active server. Also, check to see that the same services are stopped on the passive server, otherwise replication will not function correctly.
This knowledge combined with the knowledge gained from other e-learning articles will assist you in achieving success with your Neverfail Continuity Engine product.
