In the previous article "using Memcached to Improve the Performance of. NET Applications", Zhou Gong described how to use Memcached in. NET to Improve the Performance of. NET applications. In actual use, Memcached may be suspended for some unpredictable reasons. Once such a situation occurs, it will again put a huge pressure on the database, therefore, you must monitor the running status of Memcached. Zhou Gong searched for the Memcached monitoring

Mongosniff can be thought of as custom-designed for MongoDB, similar to tcpdump for TCP/IP network traffic analysis. Mongosniff is often used to drive development.Note: Mongosniff require

In the performance testing process, it is of great significance to monitor host resources. On the one hand, during the test, you can determine whether the pressurization is successful and whether the system can withstand the current pressure to ensure system security. On the other hand, after the test, you can sort the monitoring data, it can provide data support for performance analysis, problem discovery, and bottleneck search. This article will int

Dstat produces meaning:During performance testing, we generally need to detect many aspects of data, including CPU usage, memory usage, network conditions, load average, process information, disk information, and so on. These data can generally be monitored using commands provided by the system, but in general, these commands are scattered, such as Vmstat,iostat,ss,netstat. But in this way, the command is too scattered, there is an urgent need for a c
