collect采集命令
命令功能
支持采集多维度性能数据，包括Miss、访存统计、
命令格式
1 | ./ksys collect [-h] [-o OUTPUT] [--verbose] [-d <sec>] [-i <sec>] [-p PID] [-c CONFIG] [-G CGROUP][-l {0,1,2,3}] ... |
工具可采集指定应用，例如：./ksys collect [workload...]，其中[workload...]替换为应用路径加应用参数，若还需要对应用指定采集参数，请在[workload...]前指定。采集时，“-p”、“-G”或应用参数中最多只能指定一个。

使用示例
执行以下命令，查看collect命令支持的功能信息：
1 | ./ksys collect -h |
返回信息如下：
USAGE
ksys collect [-h] [-o OUTPUT] [-d <sec>] [-i <sec>] [-p PID] [-c CONFIG] [-l {0,1,2,3}] ...
Using config.yaml can carry out detailed parameter configuration. Refer to the
comments in config.yaml for details.
DESCRIPTION
Create a collection command line task.
POSITIONAL ARGUMENTS
workload
Specify workload parameters: contains the application and application parameters.
options:
-h, --help
show this help message and exit
-o OUTPUT, --output OUTPUT
Output the full path.
--verbose
Display more metric message
-d <sec>, --duration <sec>
Duration in seconds for the task collect. The minimum value is 1, If not explicitly specified, the task will collect data continuously. The user can use Ctrl+ \ to cancel the
task or Ctrl+ C to stop the task collection and enter the analysis.
-i <sec>, --interval <sec>
Interval in seconds for sampling. The minimum value is 1 and the default value is 1. The maximum value cannot exceed the collection duration. It is advisable to set the
interval to no more than one-tenth of the total collection duration. The time for collecting hotspot data in each subreport depends on the interval parameter.
-p PID, --pid PID
Analyze existing process. When pid does not exist, the collection will stop halfway. When this option is enabled, the hotspot collection can provide support for on-cpu/off-
cpu check.
-c CONFIG, --config CONFIG
Input the path of the config yaml file. The file format must be consistent with the sample.
-G CGROUP, --cgroup CGROUP
Monitors events in a specified cgroup. Only cgroup v1 and v2 are supported; hybrid cgroup configurations are not supported.
-l {0,1,2,3}, --log-level {0,1,2,3}
Set the log level (0=DEBUG, 1=INFO, 2=WARNING, 3=ERROR), which defaults to 1(INFO).

回显信息中指标区分系统维度（System wide）、应用维度（Application level）、PID维度（Process level）和cgroup维度（Cgroup level）。
- 对系统进行采集，性能数据为系统维度。
- 对应用进行采集，性能数据为系统维度和应用维度。
- 对进程进行采集，性能数据为系统维度和PID维度。
- 对cgroup进行采集，性能数据为系统维度和cgroup维度。
