Server performance monitoring: Performance Monitoring Tool

Performance monitoring tool: 1. Task Manager 2. Performance Logs and alarms I. Task Manager 1. Purpose: display applications running on the system Program Process, CPU, memory, and other usage and statistical information. 2. Open Mode (local or remote) 1> right-click the blank area in the taskbar and select "Task Manager" 2> CTRL + ALT + del ctrl + ALT + end 3> Ctrl + Shift + ESC 3.1> how to end a task and how to create a new task; 2> each application has a corresponding process; 3> modify the information of the displayed columns; performance Console 1. Start -- Management Tools -- Performance 2. System Monitor: monitors memory, hard disk, and CPU usage by default; 1> add and delete objects; 2> Performance objects: hardware or software 3> View performance in different ways; 3. Performance Logs and alarms; 1> create log settings 2> Start and Stop records 3> view log files with system monitor

Server performance monitoring: Create a performance alarm

Create performance alert
1> open the performance console and select "Performance Logs and alarms ";
2> right-click "alarm", select "new alarm settings", and add as prompted;
3> note: the alert recipient must enable the messenger service.

Server performance monitoring: monitors CPU Performance

1.% processor time CPU utilization, generally lower than 85%, the lower the better;
2. System: Number of queue threads of the processor queue lenght, generally less than 10, the lower the better;
3. Server work queues: length of the current server job queue of the queues lenght CPU, generally less than 4, the lower the better
4. Number of hardware interrupt requests received by the interrupts/sec processor per second. (The Windows2003 series can process thousands of interrupted programs per second). The lower the program, the better.
Solution: 1. Upgrade CPU 2. Add multiple CPUs

Server performance monitoring: monitor memory performance

1. Pages/sec System reads or writes pages from the virtual memory per second. The total number of pages normally ranges from 0 ~ Between 20, the lower the better;
2. available bytes System Total number of available physical memory bytes, generally greater than 5% of the total physical memory, the higher the better;
3. The committed bytes system has reserved the number of bytes of physical memory for the virtual memory, which is generally lower than the total number of physical memory. The lower the value, the better;
4. The total number of physical memory bytes that the pool nonpaged bytes occupies by the operating system and cannot be written into the virtual memory, which is generally stable.
5. The number of times page faults/sec does not find the data required by the application in the physical memory per second, generally less than 5, the lower the better;
The key to solving the problem when the above counter exceeds the range: 1. Process 2. Memory

Server performance monitoring: monitors disk Performance

1.% disk Time disk utilization. The disk drive represents the percentage of time used by the read/write requests to provide services, generally less than 50%, the lower the better;
2. Current disk queue lenght is currently waiting for the number of disk read/write requests, generally between 0-2, the lower the better;
3. avg. Disk Bytes/transfer average number of bytes transmitted by the system from the disk for each write or read operation. The higher the average, the higher the transmission efficiency of the disk;
4. The total number of bytes that the disk Bytes/sec system can read or write from the disk per second. The higher the speed, the higher the transmission speed.
Solution to the problem that the values of the first two counters are out of the range: disk upgrade: for example, replacing a disk with a fast transmission speed.

Server performance monitoring: monitors network performance

1. Network Utilization (in Task Manager) network utilization, generally lower than 30%, the lower the better;
2. Network Interface: the total number of bytes that the bytes sent/sec Nic can send per second. The higher the speed, the faster the NIC sends.
3. Network Interface: the total number of bytes that the bytes total/sec Nic can send and receive per second. The higher the speed, the faster the speed;
4. SERVER: the total number of bytes received by the bytes received/sec server from the network per second, less than 50% of the network bandwidth
