文件打包存储到/var/kylin-sysassist/collect/systemlog-2025-09-04-10-53-18.tar.gz，解压这个压缩包.
解压后看到很多目录，比如：
activeinfo/：激活信息、KMS 日志。
mem/：内存碎片信息（extfrag_index、unusable_index）。
network/：网络配置、端口、UDP/TCP 状态。
processXXXX/mem/：某些进程的内存采样数据，包括 mem_info 和调用栈 stack.txt。
sosreport/：系统完整 sosreport 报告。
作用：这是 sysassist 收集到的系统快照，能用来定位问题（内存、网络、进程等）。

[#####################################] (100%) complete
Check complete
Report path: /var/kylin-sysassist/syscheck/sysCheckReport工具执行全面检查，生成报告 /var/kylin-sysassist/syscheck/sysCheckReport。
作用：一次性做健康体检，快速发现风险配置或隐患。
ls /var/kylin-sysassist/syscheck/
bugreport：显示高危 bug（这里 0 个）。
cvereport：显示系统已知漏洞（这里 0 个）。
rpm_qa.txt：系统安装的 rpm 包列表，便于复现环境或排障。
sysCheckReport：详细的健康检查结果，包括：
漏洞/bug 数量。
基础配置（kdump、sysstat 已启用，serial 未配置）。
内核参数检查（哪些 panic 选项没启用，给出建议）。
irqbalance 服务状态。
IO 调度策略（mq-deadline）。
logrotate 策略（30 份，单文件 4MB）。
内存健康：未检测到高压力，无严重碎片，无 OOM 记录。
系统资源使用率：CPU 2.26%，内存 10.55%，磁盘 3.43%，swap 未用。
最后给出优化建议（如配置串口、调整内核参数、提高 vm.min_free_kbytes）。
作用：让管理员快速看到潜在风险（安全漏洞、内核参数、资源不足），并给出优化建议。
总结
你执行的整个流程其实就是 安装工具 → 收集系统状态 → 开启监控 → 做健康体检 → 查看报告。
collect → 全面采集并保存快照。
monitor → 长期后台监控，支撑后续 panalysis/nanalysis。
syscheck → 一次性体检，发现 bug、cve、安全隐患。
报告文件在 /var/kylin-sysassist/{collect,syscheck}/，可供后续分析或上报支持团队。
