top command and options

Back to performance measurement commands

The top program provides a dynamic real-time view of a running system. It can display system summary information as well as a list of processes or threads currently being managed by the Linux kernel.

Type the following command:

$ top

The top command used to display all the running and active real-time processes in ordered list and updates it regularly. Press ‘c‘ option in running top command, it will display absolute path of running process.

If you want to kill a running process then use kill command as - {kill -9 <process-id>}

Press (Shift+W) to save the running top command results under /root/.toprc.

OPTIONS

-u | -U :User-filter-mode as: -u | -U number or name

Display only processes with a user id or user name matching that given. The '-u' option matches on effective user whereas the '-U' option matches on any user (real, effective, saved, or filesystem).

Prepending an exclamation point ('!') to the user id or name instructs top to display only processes with users not matching the one provided.

$ top -u tarun

replace tarun with your username ;-)

-c :Command-line/Program-name toggle Starts top with the last remembered 'c' state reversed. Thus, if top was displaying command lines, now that field will show program names, and visa versa. See the 'c' interactive command for additional information. You can use this command to display absolute path of running process.

$ top -u tarun

-d :Delay-time interval as: -d ss.t (secs.tenths) Specifies the delay between screen updates, and overrides the corresponding value in one's personal configuration file or the startup default.

$ top -d 1

No screen capture, try it yourself ;-)

Using chrome console to test xPath and css selectors

Note: If you are new to java and selenium then start with selenium java training videos . Since the advent of selenium there have been many plugin to test xPath / css selectors but you don’t need any of them if you have chrome browser. Using Chrome console you can test both xPath and css selectors. Launch website to be tested in chrome browser and hit F-12 and you would see chrome console opened in lower pane of application - Hit escape key and console would open another pane to write element locators - And now you can start writing xPath or css selectors in chrome console and test them - The syntax for writing css id - $$(“ ”) And hit the enter key. If your expression is right then html snippet of the application element corresponding to the css selector would be displayed - If you mouse over the html snippet in chrome console then it would highlight the corresponding element in application - If you want to clean console of previously wri

Verify email confirmation using Selenium

Note: If you are new to java and selenium then start with selenium java training videos . Email confirmation seems to be integral part of any registration process. I came across an application which lets you provide your email address. You can follow the sign up link in you mail and then complete the registration process. Lets consider we provide GMail address for it. Now if were to use only Selenium then we would have to follow following steps - Launch GMail using Selenium; Some how search for new mail in the list of available mails; Some how click on it; Parse the mail message; Get the registration link; Follow up with registration process What do you think of an approach in which you can

Distributed Load Testing with JMeter

Distributed Testing with JMeter When one JMeter client is not able to offer amount of threads required for load testing then distributed testing is used. In distributed testing - One instance of JMeter client can control number of JMeter instances and collect data from them Test plan does not need to be copied to each server, the client sends it to all servers note - JMeter will run all the threads on all the servers, hence 100 threads on 5 JMeter server would pump 500 threads in total. If many server instances are used, the client JMeter can become overloaded and so the client network connection. This has been improved in latest versions of JMeter by switching to Stripped modes, but you should always check that your client is not overloaded When Client (master) and Server (slave) nodes are on same network (no SSH required) Configure Client Node Herein client is referred as the machine controlling test execution on other JMeter nodes. This is also referred
