About observability-mcp

- 正式环境的 Elasticsearch 日志 - 测试环境的 SkyWalking 日志和 Trace - Prometheus 或 VictoriaMetrics 指标

- none:不认证 - basic:用户名和密码 - bearer:Bearer Token - apikey:API Key

- Linux - Python 3.11 或更高版本 - 可以访问 Elasticsearch、SkyWalking 和指标后端

注意:容器中的 127.0.0.1 指向容器自己。如果 Elasticsearch、SkyWalking 或 Prometheus 在其他机器上,.env 中应填写那台机器可访问的 IP 或域名。

- 用户提到测试环境或测试线:查询 SkyWalking - 用户提到正式环境或生产环境:查询 Elasticsearch - 用户没有说明环境:默认查询正式环境 Elasticsearch - 查询无结果时不会自动跨环境重试,而是提示确认环境

- listlogindices:列出 Elasticsearch 索引、Alias 或 Data Stream - searchlogs:查询正式环境 Elasticsearch 日志 - listskywalkingservices:列出测试环境 SkyWalking 服务 - searchskywalkinglogs:查询测试环境 SkyWalking 日志 - getskywalkingtrace:查询测试环境 SkyWalking Trace

- traceid - nodeip - keyword - level - starttime、endtime - index - limit

- queryinstant:查询某个时刻的 PromQL - queryrange:查询一段时间内的 PromQL - getlabelvalues:查询某个标签的可选值

Profile 用来告诉服务不同索引中的时间、消息、级别、Trace ID、节点和错误堆栈 分别存在哪些字段中。调用者不需要传 Profile,服务会根据索引自动选择。

- filebeat-、logs-ecs-:使用 ecs - applog-:使用 offset-log - 其他索引:使用 generic

30000 通常是 SkyWalking UI 端口,不是首选的 OAP GraphQL 地址。

推荐指定较小的索引范围和时间范围。limit=5 只限制返回数量,不代表 Elasticsearch 只检查 5 条数据。
