Server monitoring is designed to determine whether the server is appropriately sized for the load that it's running. This document won't be able to guess the tools available to the I.T. department to perform this monitoring.
All servers in the MES environment should be monitored but especially the Applications, Process Historian and SQL servers. The OPC servers should be monitored for a short period after installing and configuring tags to determine if they are sized correctly.

Task Manager
Monitoring can be performed manually by using Task Manager. Task Manager provides information about applications currently running on your system, the processes and memory usage or other data about those processes, and statistics about memory and processor performance. Although useful as a quick reference to system operation and performance, Task Manager lacks the logging and alert capabilities so it should be used as a current real time reference of how the server is operating "now".
The first time you open task manager on Windows Server, you will be presented with a minimal display.

Hard Drive Space (Free Space)
If your server runs out of disk space, then it will obviously affect server performance. All data files (i.e.,. SQL Server databases) and log files should be configured to reside on the largest drive on the server.
It is important to regularly monitor the available free disk space on:
Process Historian: The drive(s) where the active archives reside
The drive(s) where the daily backups reside.
SQL: The drives where the .mdf and ldf files reside
The drives where the tempdb files reside.
Application Server:The drive where the log files reside.
