stack
|
||||
=====
|
||||
|
||||
Print out the full call stack trace containing the current method.
|
||||
|
||||
Most of the time, we know the method being invoked but not always we know **HOW being invoked**; `stack` can be a great help to locate the *source* for you.
|
||||
|
||||
### Parameters
|
||||
|
||||
|Name|Specification|
|
||||
|---:|:---|
|
||||
|*class-pattern*|pattern for the class name|
|
||||
|*method-pattern*|pattern for the method name|
|
||||
|*condition-express*|condition expression|
|
||||
|[E]|turn on regx matching while the default is wildcards matching|
|
||||
|`[n:]`|calling times|
|
||||
|
||||
F.Y.I
|
||||
1. any valid OGNL expression as `"{params,returnObj}"` supported;
|
||||
2. filter by time cost as `trace *StringUtils isBlank '$cost>100'`; calling stack with only time cost higher than `100ms` will be printed.
|
||||
|
||||
Attention:
|
||||
1. `$cost` can be used in `watch/stack/trace`;
|
||||
2. using `#cost` in Arthas 3.0 instead of `$cost`.

|
||||
Startup script is as follows:
|
||||
|
||||
```bash
|
||||
./as.sh <PID>[@IP:PORT]
|
||||
```
|
||||
|
||||
|
||||
|
||||
### Parameter Description
|
||||
|
||||
* PID: Target Java process ID(Make sure that the user executing the command has sufficient permissions to operate the target Java process.)
|
||||
|
||||
* IP: The address that Arthas Server listens on, the default value is `127.0.0.1`. Arthas allows multiple users to access simultaneously without interfering with each other.
|
||||
|
||||
* PORT: Arthas Server port，the default value is 3658
|
||||
|
||||
### Sample
|
||||
|
||||
* If you do not specify IP and PORT, the default is 127.0.0.1 and 3658
|
||||
|
||||
> ./as.sh 12345
|
||||
|
||||
Equivalent to:
|
||||
|
||||
> ./as.sh 12356@127.0.0.1:3658
|
||||
|
||||
### Remote Diagnosis
|
||||
|
||||
After starting Arthas Server, users can use `telnet` connect to the remote Arthas Server, for example：
|
||||
|
||||
```bash
|
||||
telnet 192.168.1.119 3658
|
||||
```
|
||||
|
||||
### sudo Support
|
||||
|
||||
If you need to switch users, such as `admin`, you need to add the -H parameter.
|
||||
|
||||
```bash
|
||||
sudo -u admin -H ./as.sh 12345
|
||||
```
|
||||
|
||||
|
||||
### Windows Support
|
||||
|
||||
`as.bat` script only supports one parameter: pid

### Usage
|
||||
|
||||
A demo:
|
||||
|
||||
```java
|
||||
public static void main(String[] args) {
|
||||
List<String> list = new ArrayList<String>();
|
||||
list.add("a");
|
||||
list.add("b");
|
||||
|
||||
List<String> list2 = new ArrayList<String>();
|
||||
list2.add("c");
|
||||
list2.add("d");
|
||||
|
||||
int len = add(list, list2);
|
||||
}
|
||||
|
||||
private static int add(List<String> list, List<String> list2) {
|
||||
int i = 10;
|
||||
while (i >= 0) {
|
||||
try {
|
||||
hehe(i);
|
||||
} catch (Throwable t) {
|
||||
t.printStackTrace();
|
||||
}
|
||||
i--;
|
||||
}
|
||||
|
||||
list.addAll(list2);
|
||||
return list.size();
|
||||
}
|
||||
|
||||
private static void hehe(int i) {
|
||||
if (i == 0) {
|
||||
throw new RuntimeException("ZERO");
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Tracing down method `add`:
|
||||
|
||||
```shell

F.Y.I
|
||||
1. just like JProfile and the like commercial software, you can `trace` down the specified method calling in Arthas;
|
||||
2. there will be some overhead using `trace` but not much;
|
||||
3. the time cost is an instructive clue for troubleshooting, which means it's not that accurate ignoring the cost it itself causes; the deeper or more the call is, the accuracy is becoming worse;
|
||||
4. `[0,0,0ms,11]xxx:yyy() [throws Exception]`，the same method calling aggregated into one line here while `throws Exception` indicates there is an exception.

Check the parameters, return values and exceptions of the methods at different times.
|
||||
|
||||
`watch` is a powerful command but due to its feasibility and complexity, it's quite hard to locate the issue effectively.
|
||||
|
||||
In such difficulties, `tt` comes into play.
|
||||
|
||||
With the help of `tt` (abbreviated from *TimeTunnel*), you can check the contexts of the methods at different times.
|
||||
|
||||
### Usage
|
||||
|
||||
Let's record the whole calling contexts:
|
||||
|
||||
```java
|
||||
$ tt -t -n 3 *Test print
|
||||
Press Ctrl+D or Ctrl+X to abort.

|
||||
- `-t`
|
||||
|
||||
record the calling context of the method `*Test.print`
|
||||
|
||||
- `-n 3`
|
||||
|
||||
limit the number of the records (avoid overflow for too many records; with `-n` option, Arthas can automatically stop recording once the records reach the limit)
|
||||
|
||||
#### Property
|
||||
|
||||
|Name|Specification|
|
||||
|---|---|
|
||||
|INDEX|the index for each call based on time|
|
||||
|TIMESTAMP|time to invoke the method|
|
||||
|COST(ms)|time cost of the method call|
|
||||
|IS-RET|end with normal return|
|
||||
|IS-EXP|end with exceptions|
|
||||
|OBJECT|`hashCode()` of the object invoking the method|
|
||||
|CLASS|class name of the object invoking the method|
|
||||
|METHOD|method being invoked|
|
||||
|
||||
#### Condition expression
|
||||
|
||||
Tips:
|
||||
1. `tt -t *Test print params[0].length==1` with different amount of parameters;
|
||||
2. `tt -t *Test print 'params[1] instanceof Integer'` with different types of parameters;
|
||||
3. `tt -t *Test print params[0].mobile=="13989838402"` with specified parameter.

F.Y.I
|
||||
1. the calling stack is little different using Arthas now instead of the original method;
|
||||
2. **Loss** of the thread local variables will be a fact since there is no way for Arthas to record the thread local info.
|
||||
3. **Potential** modifications of objects can happen since only a reference will be recorded by Arthas while later process might modify objects without Arthas's watch.

watch
|
||||
=====
|
||||
|
||||
Monitor the methods in data aspect including `return value`, `exceptions` and `parameters`.
|
||||
|
||||
With the help of [OGNL](https://en.wikipedia.org/wiki/OGNL), you can easily check the details of the variables.
|
||||
|
||||
### Parameters & Options
|
||||
|
||||
There are four different usage scenarios for `watch` command, which makes it the most complicated command in Arthas.
|
||||
|
||||
|Name|Specification|
|
||||
|---:|:---|
|
||||
|*class-pattern*|pattern for the class name|
|
||||
|*method-pattern*|pattern for the method name|
|
||||
|*express*|expression to monitor|
|
||||
|*condition-express*|condition expression|
|
||||
|[b]|before invoking|
|
||||
|[e]|encountering exceptions|
|
||||
|[s]|returned normally|
|
||||
|[f]|returned normally and abnormally|
|
||||
|[E]|turn on regx matching while the default is wildcards matching|
|
||||
|[x:]|the depth to print the specified property with default value: 1|
|
||||
|
||||
F.Y.I
|
||||
1. any valid OGNL expression as `"{params,returnObj}"` supported
|
||||
2. there are four *watching* points: `-b`, `-e`, `-s` and `-f` (the first three are off in default while `-f` on);
|
||||
3. at the *watching* point, Arthas will use the `expression` to calculate the values and print them out;
|
||||
4. `in-parameters` and `out-parameters` are different since they can be modified; `params` stands for `in-parameters` in `-b`while `out-parameters` in other *watching* points;
|
||||
5. there is no `return value` and `exceptions` when using `-b`.

||||

|
||||
|
||||
### Usage
|
||||
|
||||
A demo:
|
||||
|
||||
```java
|
||||
public void execute() {
|
||||
List<String> list = new ArrayList<String>();
|
||||
list.add("a");
|
||||
list.add("b");
|
||||
|
||||
List<String> list2 = new ArrayList<String>();
|
||||
list2.add("c");
|
||||
list2.add("d");
|
||||
|
||||
int len = add(list, list2);
|
||||
}
|
||||
|
||||
private static int add(List<String> list, List<String> list2) {
|
||||
list.addAll(list2);
|
||||
return list.size();
|
||||
}
|
||||
```
|
||||
#### Check the `out-parameters`and `return value`
|
||||
|
||||
```shell
|
||||
$ watch com.alibaba.sample.petstore.web.store.module.screen.ItemList add "{params,returnObj}" -x 2
|
||||
Press Ctrl+C to abort.
|
||||
Affect(class-cnt:1 , method-cnt:1) cost in 44 ms.
|
||||
@ArrayList[
|
||||
@Object[][
|
||||
@ArrayList[isEmpty=false;size=4],
|
||||
@ArrayList[isEmpty=false;size=2],
|
||||
],
|
||||
|
||||
@Integer[4],
|
||||
]
|
||||
```
|
||||
|
||||
#### Check `in-parameters`
|
||||
|
||||
```shell
|
||||
$ watch com.alibaba.sample.petstore.web.store.module.screen.ItemList add "{params,returnObj}" -x 2 -b
|
||||
Press Ctrl+C to abort.
|
||||
Affect(class-cnt:1 , method-cnt:1) cost in 48 ms.
|
||||
@ArrayList[
|
||||
@Object[][
|
||||
@ArrayList[isEmpty=false;size=2],
|
||||
@ArrayList[isEmpty=false;size=2],
|
||||
],
|
||||
|
||||
null,
|
||||
]
|
||||
```
|
||||
|
||||
Compared to the previous *check*:
|
||||
1. size of `params[0]` is `2` instead of `4`;
|
||||
2. `return value` is `null` since it's `-b`.
|
||||
|
||||
|
||||
#### Check *before* and *after* at the same time
|
||||
|
||||
```shell
|
||||
$ watch com.alibaba.sample.petstore.web.store.module.screen.ItemList add "{params,returnObj}" -x 2 -b -s
|
||||
Press Ctrl+C to abort.
|
||||

],
|
||||
|
||||
@Integer[4],
|
||||
]
|
||||
```
|
||||
|
||||
F.Y.I
|
||||
1. the first block of output is the *before watching* point;
|
||||
2. the order of the output determined by the *watching* order itself (nothing to do with the order of the options `-b -s`).
|
||||
|
||||
#### Using `-x` to check more details
|
||||
|
||||
```shell
|
||||
$ watch com.alibaba.sample.petstore.web.store.module.screen.ItemList add "{params,returnObj}" -x 3
|
||||
Press Ctrl+C to abort.
|
||||

|
||||
|

#### Using condition expressions to locate specific call
|
||||
|
||||
```shell
|
||||
$ watch com.alibaba.sample.petstore.biz.impl.UserManagerImpl testAdd "{params, returnObj}" "params[0].equals('aaa')" -x 2
|

@Integer[6],
|
||||

|
||||
```
|
||||
|
||||
#### Check `exceptions`
|
||||
|
||||
```shell
|
||||
$ watch com.alibaba.sample.petstore.biz.impl.UserManagerImpl testAdd "{params, throwExp}" -e -x 2
|
