Canal Server exposes Prometheus metrics. The official example uses port 11112, configured by canal.metrics.pull.port in canal.properties:

properties

canal.metrics.pull.port=11112

Verify the endpoint:

bash

curl -fsS http://127.0.0.1:11112/metrics | grep canal_instance | head

Create conf/input.prometheus/canal.toml:

toml

interval = 15

[[instances]]
urls = ["http://127.0.0.1:11112/metrics"]
url_label_key = "canal_server"
url_label_value = "{{.Host}}"
labels = { job = "canal" }

Do not overwrite Canal's destination or instance labels because the dashboard variables depend on them. TPS, delay, and client panels require a running destination and real binlog traffic.
