Supported OS
This check monitors Hudi.
It is compatible with Hudi versions 0.10.0
and above.
The Hudi check is included in the Datadog Agent package. No additional installation is needed on your server.
Configure the JMX Metrics Reporter in Hudi:
hoodie.metrics.on=true
hoodie.metrics.reporter.type=JMX
hoodie.metrics.jmx.host=<JMX_HOST>
hoodie.metrics.jmx.port=<JMX_PORT>
Edit the hudi.d/conf.yaml
file, in the conf.d/
folder at the root of your
Agent’s configuration directory to start collecting your hudi performance data.
See the sample hudi.d/conf.yaml for all available configuration options.
This check has a limit of 350 metrics per instance. The number of returned metrics is indicated when running the Datadog Agent status command. You can specify the metrics you are interested in by editing the configuration. To learn how to customize the metrics to collect see the JMX Checks documentation for more detailed instructions. If you need to monitor more metrics, contact Datadog support.
Run the Agent’s status
subcommand and look for hudi
under the Checks section.

Available for Agent versions >6.0
Hudi uses the log4j
logger by default. To customize the format, edit the log4j.properties
file in either your Flink or Spark conf
directory. An example log4j.properties
file is:
log4j.rootCategory=INFO, file
log4j.appender.file=org.apache.log4j.FileAppender
log4j.appender.file.File=/var/log/hudi.log
log4j.appender.file.append=false
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss,SSS} %-5p %-60c %x - %m%n
By default, Datadog’s integration pipeline supports the following conversion pattern:
%d{yyyy-MM-dd HH:mm:ss,SSS} %-5p %-60c %x - %m%n
An example of a valid timestamp is: 2020-02-03 18:43:12,251
.
Clone and edit the integration pipeline if you have a different format.
Collecting logs is disabled by default in the Datadog Agent, enable it in your datadog.yaml
file:
logs_enabled: true
Uncomment and edit the logs configuration block in your hudi.d/conf.yaml
file. Change the path
and service
parameter values based on your environment. See the sample hudi.d/conf.yaml for all available configuration options.
logs:
- type: file
path: /var/log/hudi.log
source: hudi
log_processing_rules:
- type: multi_line
pattern: \d{4}\-(0?[1-9]|1[012])\-(0?[1-9]|[12][0-9]|3[01])
name: new_log_start_with_date
The Hudi integration does not include any events.
hudi.can_connect
Returns CRITICAL
if the Agent is unable to connect to and collect metrics from the monitored Hudi instance, WARNING
if no metrics are collected, and OK
otherwise.
Statuses: ok, critical, warning
