values provided by systems, web, and databases are insufficient. In many cases, we need to define specific monitoring values to monitor our systems. You may first think of performance counters. performance counters can be easily defined through custom category and counter to implement and monitor specific values. For

Label:General countersCollects server performance information for operating system servers, including processor, disk, network, memory Processor Processor 1.1% Processor time refers to the percentage that the processor uses to perform non-idle threads. This counter allows you to determine the current percentage of CPU usage for the server. 1.2% Privileged is the percentage of time that the process thread spends executing code in privileged mode.

performance counters to solve a database storage problem. During this process, I noticed some very strange phenomena: even though no operations are performed in the database, there are still write activities in the database files. This situation exists in both data and log files. This situation continues even when I make sure that I am not connected to SQL Server. Since there is no connection, how can I/O
