![需要性能副驾驶 (pcp) 吗?和 pmlogger 文件夹已满](https://linux22.com/image/230594/%E9%9C%80%E8%A6%81%E6%80%A7%E8%83%BD%E5%89%AF%E9%A9%BE%E9%A9%B6%20(pcp)%20%E5%90%97%EF%BC%9F%E5%92%8C%20pmlogger%20%E6%96%87%E4%BB%B6%E5%A4%B9%E5%B7%B2%E6%BB%A1.png)
在由 rhel-8.9-x86-64.iso 构建的 Redhat 8.9 系统上带图形用户界面的服务器,我假设默认情况下安装了以下 rpm(见下文)。
该文件夹/var/log/pcp/pmlogger/<hostname>/
包含大约 200 个文件,大部分都经过压缩,.xz
但该文件夹大小为 2 GB。
- 它是什么
pcp
?我真的需要安装它吗?它有什么功能是我离不开的? - 有没有办法防止
pmlogger
文件夹大小变得太大?可以删除该文件夹中的内容吗? - 根据
yum remove pcp
下面显示的结果,如果我继续删除 ,是否存在任何突出的问题pcp
?
。
# yum remove pcp
