Free tier · Enterprise AI Agent upgrades at kingai.work

My Understanding / 我的理解

EN: This skill reads the last 200 lines of the systemd journal (journalctl -n 200 --no-pager) and the kernel ring buffer (dmesg --level=err,warn), analyzes them for errors, warnings, and anomalies, then produces a categorized report in Chinese. Categories include: security events (authentication failures, sudo violations), system errors (kernel panics, OOM), hardware issues (disk errors, memory errors, thermal throttling), and service failures (unit crashes, restart loops).

CN: 该技能读取 systemd 日志的最后 200 行（journalctl -n 200 --no-pager）和内核环形缓冲区（dmesg --level=err,warn），分析其中的错误、警告和异常，然后生成分类的中文报告。分类包括：安全事件（认证失败、sudo 违规）、系统错误（内核恐慌、OOM）、硬件问题（磁盘错误、内存错误、热节流）和服务故障（单元崩溃、重启循环）。

Design Philosophy / 设计理念

EN: "Prioritize by severity, contextualize by category." The skill collects logs from two complementary sources (systemd journal = userland services, dmesg = kernel/hardware) because they cover different failure domains. Output is sorted by severity within each category so the most critical issues appear first. Frequency analysis (how many times an error repeats) helps distinguish chronic issues from one-off events.

CN： "按严重性排序，按类别归类。" 该技能从两个互补来源收集日志（systemd 日志 = 用户态服务，dmesg = 内核/硬件），因为它们覆盖不同的故障域。输出在每个类别内按严重性排序，使最关键的问题优先显示。频率分析（某个错误重复多少次）有助于区分慢性问题和偶发事件。

Triggers / 触发场景

English	中文
Server experiencing issues — "check the logs"	服务器出现问题 — "查看日志"
After a crash or unexpected reboot	系统崩溃或意外重启后
Regular health checks / morning inspection	常规健康检查 / 晨检
CI build failures with unknown cause	CI 构建失败原因不明
User reports "something is wrong" without specifics	用户报告"出了点问题"但不具体
Investigating service restart loops	调查服务重启循环
Monitoring new hardware for early failure signs	监控新硬件是否出现早期故障迹象

Check / Diagnostic Commands & Scoring

bash

# 1. Last 200 journal entries (score: 2 pts) — PRIMARY SOURCE
journalctl -n 200 --no-pager

# 2. Journal errors/warnings only (score: 2 pts)
journalctl -p err -n 100 --no-pager

# 3. Kernel errors and warnings (score: 2 pts) — HARDWARE SOURCE
dmesg --level=err,warn 2>/dev/null || dmesg | grep -iE 'error|warn|fail'

# 4. Failed systemd units (score: 1 pt)
systemctl --failed --no-legend

# 5. Recent authentication failures (score: 1 pt)
journalctl -u sshd -u sudo --since "24 hours ago" -p err --no-pager -n 50

# 6. OOM killer events (score: 1 pt)
journalctl -k --since "24 hours ago" | grep -i "oom_killer\|out of memory"

# 7. Disk errors in kernel logs (score: 1 pt)
dmesg | grep -iE 'ata.*error|i/o error|buffer i/o error|sd.*fail'

Health score: /10 — Deduct 2 pts if journalctl returns nothing (no systemd), 1 pt if dmesg needs sudo, 1 pt if no errors found (neutral, not a penalty — the system is healthy).
