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
