示例

bailongma -h tdengine -p 6030 -u root -P taospass --listen 0.0.0.0:10101

它将监听端口 10101（默认为 10230）。

在 prometheus.yml 中配置

remote_write:
  - url: "localhost:10101/adapters/prometheus/write"
remote_read:
  - url: "localhost:10101/adapters/prometheus/read"

默认数据库是 prometheus，使用查询选项 database 修改它，配置文件如下

remote_write:
  - url: "localhost:10101/adapters/prometheus/write?database=prom1"
remote_read:
  - url: "localhost:10101/adapters/prometheus/read?database=prom1"

构建和安装

cargo build
cargo install --path .

blm-bench-prom

cargo build 也会产生一个基准工具。

blm-bench-prom http://127.0.0.1:10230/adapters/prometheus/test5 \
  --points 10 \
  --metrics 10 \
  --interval 1000 \
  --chunks 1000 \
  --samples 100
