docker check cpu usage

Test and solution for high memory usage and high CPU usage of MySQL. The changes are as follows: Innodb_buffer_pool_size = 576 M-> 256 M InnoDB Engine Buffer occupies a large proportion, the first is to use it to open the knifeQuery_cache_size = 100 M-> 16 M query CacheTmp_table_size = 102 M-> 64 M temporary table sizeKey_buffer_size = 256 m-> 32 M After the mysq

In the absence of nagios monitoring software, as long as the server can be on the Internet, you can send mail to remind the Administrator system load and CPU usage. First, install the following Linux mail client msmtp software (similar to a foxmail tool) 1. Download and install:Http://downloads.sourceforge.net/msmtp/msmtp-1.4.16.tar.bz2?modtime=1217206451big_mirror=0 Copy Code code as follows:

: Of course, this requires that you have no site and have an independent application pool corresponding to it. The application pool name should preferably be the site name, for example: About the application pool configuration of IIS, I won't talk about it here. If you don't understand it, you can search Then open the task manager, such: Observe that the process is w3wp.exe, check the CPU

The syntax is as follows:SELECT t1.pid, t2.userid, t3.count, t1.dateFROM _ mydata AS t1Left join _ myuser AS t3 ON t1.userid = t3.useridLeft join _ mydata_body AS t2 ON t1.pid = t3.pidOrder by t1.pidLIMIT 0, 15 Call show columns to check the structure of the three tables:MySQL> show columns from _ myuser;MySQL> show columns from _ mydata;MySQL> show columns from _ mydata_body; Finally, the problem is found: _ mydata table, only a pr

the value of tmp_table_size is the default 32 M, So we modified My. ini and assigned the value of tmp_table_size to 200 M: D: webmysql> notepad c: windowsmy. ini[Mysqld]Tmp_table_size = 200 M Then restart the MySQL service. CPU usage is slightly reduced. The previously used CPU usage waveform is 100% in a straight lin

in kernel mode and user mode. we can get the difference between the value 2 at a certain interval and the value 2 obtained earlier, and we will get the time at which the thread/process runs on the CPU during this interval, divide the time by the interval to get the corresponding CPU usage. For example, if the running time is 10 ms and the interval is 1000 ms, th

(Seconds) sometimes you need to check how much CPU the script consumes. you need to check the values of "user-mode time" and "system kernel time. The second and microsecond sections are provided separately. you can divide the microseco

So I created an index for the _ mydata table based on the field userid:

Based on the queens version deployed in Kolla-ansible, you can view the resource usage of openstack Based on docker stats and find that neutron_openvswitch_agent has been occupying 100% of CPU resources. This problem has been fixed in the latest queens and rocky versions, to solve this problem, follow these steps: SolutionReplace the/var/lib/Kolla/venv/lib/pytho

In Windows + IIS6, w3wp memory usage often fails to be released in time, resulting in slow server response.After studying it today, you can make the following configurations:1. Separate applications for each website in IISProgramPool configuration. That is, they do not affect each other.2. Set the recycle time of the application pool. The default value is 1720 hours, which can be modified as needed. At the same time, set the number of w3wp processes t

　 The reason for high CPU usage 1. The computer runs a large program, such as large games, 3D network games and so on, this situation is usually normal, such programs require more CPU resources, users will be large program exit for a period of time, the CPU utilization rate is basically back to normal; 2. If the com

m:D:/web/mysql> notepad C:/Windows/My. ini[Mysqld]Tmp_table_size = 200 m Then restart the MySQL service. CPU usage is slightly reduced. The previously used CPU usage waveform is 100% in a straight line, and now it is 97% ~ 100%Between ups and downs. This indicates that adjusting the tmp_table_size parameter can impr

Solution to high CPU usage in win10 System With the release of the win10 preview version, more and more users have installed the win10 system to experience the power of the win10 system. In a computer, CPU is the core part. Some users find that the CPU usage is very high, s
