| 1 | +# Redis Streams Exporter |
| 2 | + |
| 3 | +Prometheus exporter for Redis Streams by the redis command `xinfo`. |
| 4 | + |
| 5 | +And this project is written by rust, it provide a painless, standalone, economical, simple monitor for the poor men who choice the lightweight queues by redis like me. |
| 6 | + |
| 7 | +## Installation and Usage |
| 8 | + |
| 9 | +### Binary |
| 10 | + |
| 11 | +[Download from github](https://github.com/cnzx219/redis-streams-expoter/releases) |
| 12 | + |
| 13 | +Then in terminal: |
| 14 | + |
| 15 | +```bash |
| 16 | +./redis-streams-exporter '--key=test-streams1;test-streams2;test-streams3' --redis=redis://127.0.0.1/0 --bind=127.0.0.1:9219 |
| 17 | +``` |
| 18 | + |
| 19 | +Or simplify: |
| 20 | + |
| 21 | +```bash |
| 22 | +./redis-streams-exporter --key=test-streams1 |
| 23 | +``` |
