#### 介绍
|
#### 介绍
|
||||||
A-Tune-BPF-Collection is BPF based tunning tools collection
|
A-Tune-BPF-Collection是BPF工具集，这些BPF程序用以跟踪内核行为模式以实时细粒度地调整内核参数，达到提升系统性能的目标。
|
||||||
|
|
||||||

||||||
软件架构说明
|
以`readahead_tune`为例来介绍A-Tune-BPF-Collection中的BPF程序。
|
||||||
|
|
||||||
|
`readahead_tune`包含两部分：
|
||||||
|
|
||||||
|
* BPF program(`readahead_tune.bpf`)：加载到内核的BPF program以跟踪ext4/xfs文件系统的文件读操作
|
||||||
|
* BPF control program(`readahead_tune`)：读取配置文件，配置BPF program的参数，随即加载BPF program到内核
|
||||||
|
|
||||||
#### 安装教程
|
#### 安装教程
|
||||||
|
|
||||||
1. xxxx
|
通过rpm命令或者yum安装`A-Tune-BPF-Collection` rpm包：
|
||||||
2. xxxx
|
|
||||||
3. xxxx
|
```
|
||||||
|
# yum install A-Tune-BPF-Collection
|
||||||
|
or
|
||||||
|
# rpm -ivh A-Tune-BPF-Collection-{version}.x86_64.rpm
|
||||||
|
```

|
以`readahead_tune`为例介绍A-Tune-BPF-Collection中的BPF程序程序使用：
|
||||||
2. xxxx
|
|
||||||
3. xxxx
|
1. （可选）默认配置文件会安装在`/etc/sysconfig/readahead_tune.conf`，也可以自己新建配置文件，通过`start_readahead_tune`命令`-c|--config`选项指令配置文件路径。若未指定配置文件，则会使用默认安装的配置文件。
|
||||||
|
|
||||||
|
```
|
||||||
|
注意：仅支持通过完整路径名指定配置文件，相对路径会无法识别；配置文件中若存在不合法的选项配置或者配置选项缺失，都会使用该选项的默认配置值。
|
||||||
|
```
|
||||||
|
|
||||||
|
2. 通过`start_readahead_tune`命令启动/加载`readahead_tune.bpf` BPF Program。命令使用方法可以使用`start_readahead_tune -h|--help`帮助命令。
|
||||||
|
3. 通过`stop_readahead_tune`命令停止/卸载`readahead_tune.bpf` BPF Program。

%description
|
||||||
|
A-Tune BPF Collection contains a set of BPF program which can interact with kernel in real time.
|
||||||
|
It has the following capabilities:
|
||||||
|
readahead_tune: trace file reading characteristics, then ajust file read mode to get maximum I/O efficency
