Trino¶

Collect Trino metrics information.

Configuration¶

Trino is an application written in Java language that can obtain metrics information through jmx.

JMX Exporter is an open-source tool used to export JMX (Java Management Extension) metrics for Java applications into Prometheus format metric data.

Obtain Trino metrics information through JMX Exporter, and collect jmx metrics information by opening DataKit's prom collector.

Download JMX Exporter¶

Coordinator Node¶

coordinator is a type of server called Trino, responsible for parsing statements, querying plans, and managing workers.

• Add jmx_config.yaml

rules:
- pattern: ".*"

• Adjust startup command

...
-javaagent:/opt/apache/trino/lib/jmx_prometheus_javaagent-0.19.0.jar=3900:/opt/apache/trino/etc/jmx_config.yaml \
-Dnode.environment=test \
-Dnode.id=trino-coordinator \
...

Among them, 3900 is an exposed port that can be accessed through the http://localhost:3900 Obtain metrics information.

DataKit Collector¶

Due to the fact that Trino can directly expose the metrics URL through JMX Exporter, it can be collected directly through the prom collector.

Perform the following actions:

cd datakit/conf.d/prom
cp prom.conf.sample trino.conf

Adjust the content of trino.conf as follows:

  urls = ["http://localhost:3900"]

  source = "trino"

  [inputs.prom.tags]
    component="trino"
  interval = "10s"

Note that the marker needs to be adjusted

Description of main parameters:

• urls: trino Metric address, where you fill in the metric URL exposed by the corresponding component
• source: Collector alias, recommended to distinguish
• interval: collection interval
• measurement_prefix: Metric set prefix for easy management of classification
