Tkprof: an executable tool that analyzes the ORACLE tracking file and generates a more user-friendly and clear output result. Step 1. set the parameter file to set the three parameters timed_staticsticesuser_dump_destmax_dump_file_sizetimed_staticstices to start or disable timed statistics (such as the CUP time and time used) Tkprof: an executable tool that analyzes the ORACLE tracking file and generates a

1. symptom description On the surface, the man-machine program crashes and all functions cannot work properly. This problem has appeared many times. It took a week to understand it. Later, we summarized the tracking process and analysis and provided three solutions.2 problem tracking 2.1 Tracking Step 1 -- top command viewing thread status Status such as CPU usag

This article and we share the main is the application of transparent link tracking tool in PHP molten related content, A look at it, I hope to everyoneLearn PHPHelpful. MoltenMolten is the application transparent link tracking Tool. molten tracks the PHP core call Library runtime information and outputs the information in zipkin/optracing format. Molten offers a variety of sapi, a variety of sampling types,

require any prior knowledge and relies entirely on the calculation of the density function values of sample points in the feature space. For a set of sampled data, the histogram method usually divides the value of the data into several equal intervals, the data is divided into several groups according to the interval, the ratio of the number of each set of data to General staff is the probability of each unit; The kernel density estimation method is similar to the Histogram method, but it has a

This article uses Java processes to illustrate 1. View the CPU usage of the Java process and its threads First use PS-EF to find the Java process ID # ps-ef|grep Java Then use the top-p PID command to view the CPU used by the process, for example: [[Email protected] ~]# top-p 23386top-11:10:52 up 124 days, 19:18, 2 users, Load average:0.00, 0.00, 0.00Tasks:1 Total, 0 running, 1 sleeping, 0 stopped, 0 zombieCpu (s): 0.0%us, 0.0%sy, 0.0%ni,100.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%stmem:16294180k Tota

Many times before, Conntrack as a link tracking mechanism, if it is extensible, then it will be a very exciting thing, when you read the n multi-document code, you find that it is indeed extensible, but not excited, because you may find:1. It can register an account extension, but the counting mechanism is primitive;2. I want to add a new extension, but have to recompile the kernel;What to do? I used to be angry to accuse the people who had realized i

Many friends who have played flying shooters are impressed by the ability to track missiles, which are often invincible, but the enemy's missiles may be a nightmare for the player. In fact, the implementation of the missile tracking method is not complicated, only need some simple plane analytic geometry knowledge can be done.The algorithm analysis assumes that the rotational angular velocity of the missile is Omega and the motion speed is v. Shows th
