说明
Loki 是主服务器，负责存储日志和处理查询 。
promtail 是代理，负责收集日志并将其发送给 loki 。
Grafana 用于 UI 展示loki

过滤指定内容
语法说明
- |=：日志行包含字符串。
- !=：日志行不包含字符串。
- |~：日志行匹配正则表达式。
- !~：日志行与正则表达式不匹配。对最近五分钟内的所有日志行进行计数
count_over_time({job="jm-admin"}[5m])
获取在过去十秒内所有非超时错误的每秒速率
rate({job="jm-admin"} |= "error" != "timeout" [10s]集合运算符
与PromQL一样，LogQL支持内置聚合运算符的一个子集，可用于聚合单个向量的元素，从而产生具有更少元素但具有集合值的新向量
| 运算符 | 说明 |
|---|---|
| sum | 计算标签上的总和 |
| min | 选择最少的标签 |
| max | 选择标签上方的最大值 |
| avg | 计算标签上的平均值 |
| stddev | 计算标签上的总体标准差 |
| stdvar | 计算标签上的总体标准方差 |
| count | 计算向量中元素的数量 |
| bottomk | 通过样本值选择最小的k个元素 |
| topk | 通过样本值选择最大的k个元素 |
统计最高日志吞吐量按container排序前十的应用程序
topk(10,sum(rate({job="fluent-bit"}[5m])) by(container))获取最近五分钟内的日志计数，按级别分组
sum(count_over_time({job="fluent-bit"}[5m])) by (level)本博客所有文章除特别声明外，均采用 CC BY-NC-SA 4.0 许可协议。转载请注明来自 ALLBS！
