classloader
|
||||
===========
|
||||
|
||||
Check the inheritance tree, urls and classes loading profiles of the class loaders.
|
||||
|
||||
It can be a great help for `ResourceNotFoundException` when you can use command `classloader`to specify a class loader to `getResources` and print all the urls of the valid resources.

getstatic
|

=========
|
||||
|
||||
Check the static fields of classes conveniently as `getstatic class_name field_name`
|
||||
|
||||
Tip: if the *field* is a composite object, you can even use [`OGNL`](https://en.wikipedia.org/wiki/OGNL) to traverse, filter and access the internal properties of it.
|
||||
|
||||
E.g. suppose `n` is a `Map` and the key is a `Enum` then if you want to get the key with a specific `Enum` value - `STOP` or `a`, you can achieve it as:
|
||||
|
||||
```
|
||||
$ getstatic com.alibaba.arthas.Test n 'entrySet().iterator.{? #this.key.name()=="STOP"}'
|
||||

De-compile specified loaded classes.
|
||||
|

`jad` helps to *de-compile* the byte code in JVM to the source code to assist you to better understand the logic behind.
|
||||
|
||||
F.Y.I
|
||||
* the de-compiled code will be grammatically highlighted for readability in Arthas Console;
|
||||
* you have to understand there might be some trivial grammar errors but it won't affect the logic understanding.

### Usage

When several class loaders loaded the same class:

1. `jad` to get the hashcode of the class loader;
|

2. `jad -c <hashcode>` to get the de-compiled class loaded by the class loader.
|

```java

|

Abbreviated from “Search-Class”; with the help of this command, you can search out all the loaded classes in JVM. Supported options are: `[d]`、`[E]`、`[f]` and `[x:]`.

|
||||
|[f]|print the fields info of the current class, which should be used along with `-d`|
|

|[x:]|the depth to print the static fields, whose default is `0` - directly invoke the `toString()`|
|

|
||||
Tip:
|
||||
1. *class-patten* supports full qualified class name (e.g. com.taobao.test.AAA and com/taobao/test/AAA)
|
||||
2. `sc` turned on the `sub-class` matching in default mode, if you do want to hide the `sub-class` please just turn it off via `options disable-sub-class true`.

======

|

Check the basic profile and stack trace of the threads.
|

|

### Parameters
|
||||
|
||||
|Name|Specification|
|
||||
|---:|:---|
|
||||
|*id*|thread id in JVM|
|
||||
|[n:]|the top n busiest with stack traces|
|
||||
|[b]|locate the threads blocking others|
|
||||
|[i `<value>`]|specify the interval to collect data to compute CPU ratios (ms)|
|
||||
|
||||
How to get the CPU ratios?
|
||||
|
||||
> Within an *specified* interval, the time cost by the thread compared to the total CPU time.
|
||||
> Take a sample (using `java.lang.management.ThreadMXBean#getThreadCpuTime`) to get the CPU time cost for all the threads and after a *specified* interval (default *100 ms*, which can be specified by `-i`), take another sample and we have the CPU time cost and the ratios naturally.
|
||||
|
||||
> Attention: this kind of operation will take time, to decrease the extra cost, you'd better expand the interval to like `5000 ms` for less performance overhead.
|
||||
|
||||
F.Y.I
|
||||
|
||||
If you'd like to check the CPU ratios from the very start of the Java process, [show-busy-java-threads](https://github.com/oldratlee/useful-scripts/blob/master/docs/java.md#-show-busy-java-threads) can be a help.

#### thread -b locate the blocking threads
|
||||
|
||||
Using `-b`, we can effectively locate the threads holding locks blocking other threads resulting in a frozen system.
|
||||
|
||||
```sh
|
||||
$ thread -b

||||
