It is found that the web server is abnormal in the monitoring, and the cpu and load will suddenly increase, and then it will return to normal in 10 minutes. Ssh connection, several php-cgi processes use 100% cpu. At that time, I suspected that some programs were not written, so I informed the development team to check them. As you can see, as the number of visits increases, several web servers found abnorma

backgroundThrough performance monitoring, it is found that a core occupancy rate of the on-line server CPU has reached 100%, and is caused by one of our key services. Fortunately, because our service processes are assumed by multiple identical worker (thread) schedules, there is no impact on services other than high CPU usage. With the last time we found the one
