Log command outputs
|
|
===================
|
|
|
|
> Log command outputs for later analysis
|
|
|
|
* By default, this behavior is turned off. To enable it, execute the command below:
|
|
|
|
```bash
|
|
$ options save-result true
|
|
NAME BEFORE-VALUE AFTER-VALUE
|
|
----------------------------------------
|
|
save-result false true
|
|
Affect(row-cnt:1) cost in 3 ms.
|
|
```
|
|
|
|
If the message above is output on the console, then this behavior is enabled successfully.
|
|
|
|
* Log file path
|
|
|
|
The command execution result will be save in `{user.home}/logs/arthas-cache/result.log`. Pls. clean it up regularly to save disk space.
|
|
|
|
### Use asynchronous job to log
|
|
|
|
```bash
|
|
$ trace Test t >> &
|
|
job id : 2
|
|
cache location : /Users/zhuyong/logs/arthas-cache/28198/2
|
|
```
|
|
|
|
By doing this, the command will run at background asynchronously, and output the execution result into `~/logs/arthas-cache/{PID}/{JobId}`:
|
|
|
|
* The background job will continue to run even if the current session is disconnected. The default job timeout value is 1 day, use global '[options](options.md)' command to alternate it.
|
|
* The execution result will be output into the file asynchronously. Pls. note the behavior of this command is not controlled by `save-result` option from global [options](options.md). No matter `save-result` is set to `true` or not, this command will write into `~/logs/arthas-cache/{PID}/{JobId}` anyway, instead of into `~/logs/arthas-cache/result.log`.
