Dear downvoters, please give me a solution or explain why downvotes my question — Hoo, Nov 27 '15 at 05:08
Make sure you have selected your application from drop down at the top of the Android Monitor tab. If there's 'No Debuggable Application' then it will show logs of entire os. — Apurva, Nov 27 '15 at 05:12
If you want logcat only for your app, then add package name in filter, then you will be able to see only logcat of your application. — Chirag Savsani, Nov 27 '15 at 05:15

Logcat is system wide, it reports on everything that's happening inside Android. This allows you to diagnose external factors that may have affected your application (and events that occurred before and after it ran)

From the docs:

The Android logging system provides a mechanism for collecting and viewing system debug output. Logs from various applications and portions of the system are collected in a series of circular buffers, which then can be viewed and filtered by the logcat command. You can use logcat from an ADB shell to view the log messages.

According to matthewrdev logcat give report of all things which is happening in your android device.

If you want logcat only for your appication, then add package name in filter, then you will be able to see only logcat of your application.

Add filter in Eclipse :

Open your logcat
Click on green "+" button
Then below dialog will display.
Add your application package name.

Now you will be able to see logcat only of your application.
