mtools does not parse MongoDB 4.4+ JSON logs. So I built mdbkit

说明与用途

mdbkit 替代了旧版 mtools，帮助 MongoDB 运维人员快速解析结构化 JSON 日志，识别最耗费资源的查询模式，获取确定性的索引建议，并构建事件时间线，全部无需连接数据库。

问题

MongoDB 4.4+ changed log format to structured JSON, breaking legacy mtools (mloginfo, mplotqueries) and leaving operators with fragile grep/jq pipelines.

结果

Operators can quickly identify the most costly query shapes, receive concrete index suggestions, and reconstruct incident timelines—all from local log files, without any network access.

工作流

• 1. Run mdbkit queries /var/log/mongodb/mongod.log to list slow query shapes and their impact.
• 2. Run mdbkit advise /var/log/mongodb/mongod.log to get deterministic index recommendations with confidence scores.
• 3. Run mdbkit triage /var/log/mongodb/mongod.log to build an incident timeline of elections, rollbacks, stalls, etc.

mdbkit reads log files you hand it. It is strictly read only.
