A fully running Linux system consists of many subsystems (introduction, Cpu,memory,io,network, ...). ), monitoring and evaluating these subsystems is part of the performance monitoring. We often need macroscopic view of the whole system state, also need microscopic look at the operation of each subsystem. Fortunately, we don't have to reinvent the wheel to monito
Linux performance monitoring and analysis tool background recently, a pre-developed system performance test is required. The system is deployed on the Linux server cluster. In high concurrency and high load scenarios, you can collect all the information (including CPU, memory, I/O, disk, and network traffic) occupied by each device... linux

Nmon (named Nigel's Monitor) is a computer performance system monitoring tool developed by IBM employees Nigel Griffiths for AIX and Linux systems. Nmon can display the operating system statistics on the screen or stored in a data file to help understand the use of computer resources, adjust direction and system bottlenecks. This system benchmark tool only needs to use one command to get a lot of important

Miniprofiler Official website: http://miniprofiler.com/A particularly useful feature of Miniprofiler is its integration with the database framework. Apart from. NET native DbConnection class, Miniprofiler also has built-in support for the Entity Framework and LINQ to SQL, Ravendb, and MongoDB. Any step that executes will include the number of queries and the time spent. To detect common errors, such as the n+1 anti-pattern, Profiler detects multiple queries with only a difference in parameter va

A disk is usually the slowest subsystem of a computer, and it is also the most prone to performance bottlenecks, because the disk is the farthest from the CPU and the CPU access to the disk involves mechanical operations, such as rotating shafts and track searching. The speed difference between hard disk access and memory access is calculated by an order of magnitude, just like A disk is usually the slowest subsystem of a computer, and it is also the
