A toy project to play music (aha, mostly Noise in fact) through Prometheus metrics.
This project is inspired by prometheus_video_renderer.
- I haven't tuned a good way for the audio sample, so maybe you won't hear any sound. I run the benchmark for a long time(1h+), and can hear the noise.
- Don't test this in the office, you may disturb your colleagues.
go build -o tiplay main.go
Start a Prometheus
Here we use
tiup to start a TiDB cluster in the machine.
# Install tiup curl --proto '=https' --tlsv1.2 -sSf https://tiup-mirrors.pingcap.com/install.sh | sh # Start a TiDB playground, this will also start a Prometheus server # Here we start a TiDB cluseter with 5.3 version tiup --tag 5.3 playground 5.3
The output may look like below:
Playground Bootstrapping... Start pd instance Start tikv instance Start tidb instance Waiting for tidb instances ready 127.0.0.1:4000 ... Done Start tiflash instance Waiting for tiflash instances ready 127.0.0.1:3930 ... Done CLUSTER START SUCCESSFULLY, Enjoy it ^-^ To connect TiDB: mysql --comments --host 127.0.0.1 --port 4000 -u root -p (no password) To view the dashboard: http://127.0.0.1:2379/dashboard PD client endpoints: [127.0.0.1:2379] To view the Prometheus: http://127.0.0.1:50344 To view the Grafana: http://127.0.0.1:3000
Run a benchmark to the TiDB, so we can query metrics from Prometheus later
Here we run a TPCC benchmark with go-tpc. We can already use this tool with
# Prepare the data tiup bench tpcc --warehouses 4 prepare # Run the benchmark tiup bench tpcc --warehouses 4 run
Long time later...
tiplay -prom_url http://127.0.0.1:50344 -track "sum(rate(tidb_executor_statement_total[1m])) by (type)"
Have a fun and please listen to the Noise!!!
