Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. After we deploy memcache, it does not mean that we should monitor the memcahce status, memory usage, and the value of hit/miss, with cacti, we can monitor the various memcache p

Performance monitoring has always been an issue that every website must seriously consider. For a large system, if you do not know the running status of each module, it is an accident, I don't even know how to cancel it. I think many software developers have noticed this.
