Enter the metric names to be included or excluded using the Metric Name parameter. Metric Name - The name of a metric that will be included or excluded during metric collection. If you do not select Health Test Metric Set or Default Dashboard Metric Set, or specify metrics by name, metric filtering will be turned off (this is the default behavior).For example, the following configuration enables the collection of metrics required for Health Tests and the jvm_heap_used_mb metric: Include only Health Test Metric Set: Selected. Include/Exclude Custom Metrics: Set to Include. Metric Name: jvm_heap_used_mb You can also view the JSON representation for this parameter by clicking View as JSON.

This value must be unique for the specific role. triggerExpression (mandatory) - A tsquery expression representing the trigger. streamThreshold (optional) - The maximum number of streams that can satisfy a condition of a trigger before the condition fires. By default set to 0, and any stream returned causes the condition to fire. enabled (optional) - By default set to 'true'. If set to 'false', the trigger is not evaluated. expressionEditorConfig (optional) - Metadata for the trigger editor. If present, the trigger should only be edited from the Edit Trigger page; editing the trigger here can lead to inconsistencies. For example, the following JSON formatted trigger configured for a DataNode fires if the DataNode has more than 1500 file descriptors opened:[{"triggerName": "sample-trigger", "triggerExpression": "IF (SELECT fd_open WHERE roleName=$ROLENAME and last(fd_open) > 1500) DO health:bad", "streamThreshold": 0, "enabled": "true"}]See the trigger rules documentation for more details on how to write triggers using tsquery.The JSON format is evolving and may change and, as a result, backward compatibility is not guaranteed between releases.

This value must be unique for the specific role. triggerExpression (mandatory) - A tsquery expression representing the trigger. streamThreshold (optional) - The maximum number of streams that can satisfy a condition of a trigger before the condition fires. By default set to 0, and any stream returned causes the condition to fire. enabled (optional) - By default set to 'true'. If set to 'false', the trigger is not evaluated. expressionEditorConfig (optional) - Metadata for the trigger editor. If present, the trigger should only be edited from the Edit Trigger page; editing the trigger here can lead to inconsistencies. For example, the following JSON formatted trigger configured for a DataNode fires if the DataNode has more than 1500 file descriptors opened:[{"triggerName": "sample-trigger", "triggerExpression": "IF (SELECT fd_open WHERE roleName=$ROLENAME and last(fd_open) > 1500) DO health:bad", "streamThreshold": 0, "enabled": "true"}]See the trigger rules documentation for more details on how to write triggers using tsquery.The JSON format is evolving and may change and, as a result, backward compatibility is not guaranteed between releases.

Enable Service Level Health Alerts	When set, Cloudera Manager will send alerts when the health of this service reaches the threshold specified by the EventServer setting eventserver_health_events_alert_threshold		true	enable_alerts	false
Enable Configuration Change Alerts	When set, Cloudera Manager will send alerts when this entity's configuration changes.		false	enable_config_alerts	false
Healthy Kafka Broker Monitoring Thresholds	The health test thresholds of the overall Kafka Broker health. The check returns "Concerning" health if the percentage of "Healthy" Kafka Brokers falls below the warning threshold. The check is unhealthy if the total percentage of "Healthy" and "Concerning" Kafka Brokers falls below the critical threshold.		Warning: 94.99 %, Critical: 49.99 %	KAFKA_KAFKA_BROKER_healthy_thresholds	false
Service Triggers	The configured triggers for this service. This is a JSON-formatted list of triggers. These triggers are evaluated as part as the health system. Every trigger expression is parsed, and if the trigger condition is met, the list of actions provided in the trigger expression is executed. Each trigger has the following fields: triggerName (mandatory) - The name of the trigger. This value must be unique for the specific service. triggerExpression (mandatory) - A tsquery expression representing the trigger. streamThreshold (optional) - The maximum number of streams that can satisfy a condition of a trigger before the condition fires. By default set to 0, and any stream returned causes the condition to fire. enabled (optional) - By default set to 'true'. If set to 'false', the trigger is not evaluated. expressionEditorConfig (optional) - Metadata for the trigger editor. If present, the trigger should only be edited from the Edit Trigger page; editing the trigger here can lead to inconsistencies. For example, the following JSON formatted trigger fires if there are more than 10 DataNodes with more than 500 file descriptors opened:[{"triggerName": "sample-trigger", "triggerExpression": "IF (SELECT fd_open WHERE roleType = DataNode and last(fd_open) > 500) DO health:bad", "streamThreshold": 10, "enabled": "true"}]See the trigger rules documentation for more details on how to write triggers using tsquery.The JSON format is evolving and may change and, as a result, backward compatibility is not guaranteed between releases.

Other

Display Name	Description	Property Name	Default Value	API Name	Required
Topic Auto Creation	Enables auto creation of topics on the server. If set to true, it attempts to produce, consume, or fetch metadata for a non-existent topic automatically create the topic with the default replication factor and number of partitions.	auto.create.topics.enable	true	auto.create.topics.enable	false
Enable Automatic Leader Rebalancing	If automatic leader rebalancing is enabled, the controller tries to balance leadership for partitions among the brokers by periodically returning leadership for each partition to the preferred replica, if that replica is available.	auto.leader.rebalance.enable	true	auto.leader.rebalance.enable	false
Enable Controlled Shutdown	Enables controlled shutdown of the broker. If enabled, the broker moves all leaders on it to other brokers before shutting itself down. This reduces the unavailability window during shutdown.	controlled.shutdown.enable	true	controlled.shutdown.enable	false
Controlled Shutdown Maximum Attempts	Number of unsuccessful controlled shutdown attempts before executing an unclean shutdown. For example, the default value of 3 means that the system will attempt a controlled shutdown 3 times before executing an unclean shutdown.	controlled.shutdown.max.retries	3	controlled.shutdown.max.retries	false
Default Replication Factor	The default replication factor for automatically created topics.	default.replication.factor	1	default.replication.factor	false
Enable Delete Topic	Enables topic deletion using admin tools. When delete topic is disabled, deleting topics through the admin tools has no effect.	delete.topic.enable	true	delete.topic.enable	false
List of Metric Reporters	List of metric reporter class names. HTTP reporter is included by default.	kafka.metrics.reporters	nl.techop.kafka.KafkaHttpMetricsReporter	kafka.metrics.reporters	false
Enable Kerberos Authentication	Enables Kerberos authentication for this Kafka service.	kerberos.auth.enable	false	kerberos.auth.enable	false
Leader Imbalance Check Interval	Defines the frequency of leader imbalance checks.	leader.imbalance.check.interval.seconds	5 minute(s)	leader.imbalance.check.interval.seconds	false
Leader Imbalance Allowed Per Broker	The percentage of leader imbalance allowed per broker. The controller rebalances leadership if the leader imbalance ratio goes above the configured value per broker.	leader.imbalance.per.broker.percentage	10 %	leader.imbalance.per.broker.percentage	false
Log Cleaner Deduplication Buffer Size	The total memory used for log deduplication across all cleaner threads. This memory is statically allocated and will not cause GC problems.	log.cleaner.dedupe.buffer.size	128 MiB	log.cleaner.dedupe.buffer.size	false
Log Compaction Delete Record Retention Time	The amount of time to retain delete messages for log compacted topics. Once a consumer has seen an original message, it has to be ensured that it also sees the delete message. If the delete message is removed too quickly, this might not happen. The configurable delete retention time helps to circumvent this issue.	log.cleaner.delete.retention.ms	7 day(s)	log.cleaner.delete.retention.ms	false
Enable Log Compaction	Enables the log cleaner to compact topics with cleanup.policy=compact on this cluster.	log.cleaner.enable	true	log.cleaner.enable	false
Log Cleaner Clean Ratio	Controls how frequently the log cleaner will attempt to clean the log. This ratio restricts the maximum space wasted by duplicates in the log. For example, if set to 0.5, then at most 50% of the log can be populated by duplicates. A higher ratio results in fewer, more efficient cleaning processes, but more wasted space in the log.	log.cleaner.min.cleanable.ratio	0.5	log.cleaner.min.cleanable.ratio	false
Number of Log Cleaner Threads	The number of background threads used for log cleaning.	log.cleaner.threads	1	log.cleaner.threads	false
Log Flush Message Interval	The number of messages written to a log partition before triggering an fsync on the log. Setting this property to a low value results in more frequent data to disk synchronization, but also has major impact on performance. For durability, Cloudera recommends the use of replication rather than depending on a single-server fsync. However, this setting can be used as an extra safety measure. If used in conjunction with log.flush.interval.ms, the log is flushed when either criteria is met.	log.flush.interval.messages		log.flush.interval.messages	false
Log Flush Time Interval	The maximum time between fsync calls on the log. If used in conjunction with log.flush.interval.messages, the log is flushed when either criteria is met.	log.flush.interval.ms		log.flush.interval.ms	false
Log Flush Scheduler Interval	The frequency, in milliseconds, with which the log flusher checks whether any log is eligible to be flushed to disk.	log.flush.scheduler.interval.ms		log.flush.scheduler.interval.ms	false
Maximum Message Size	The maximum size of a message that the server can receive. This property has to be in sync with the maximum fetch size the consumers use. Otherwise, an unruly producer could publish messages that are too large for consumption.	message.max.bytes	1000000 B	message.max.bytes	false
Minimum Number of Replicas in ISR	The minimum number of replicas in the in-sync replica needed to satisfy a produce request where required.acks=-1 (that is, all).	min.insync.replicas	1	min.insync.replicas	false

Default Number of Partitions	The default number of partitions for automatically created topics.	num.partitions	1	num.partitions	false
Number of Replica Fetchers	Number of threads used to replicate messages from leaders. Increasing this value increases the degree of I/O parallelism in the follower broker.	num.replica.fetchers	4	num.replica.fetchers	false
Offset Commit Topic Number of Partitions	The number of partitions for the offset commit topic. Changing this value after deployment is currently unsupported, therefore, Cloudera recommends using a higher number of partitions (for example, 100-200) for production.	offsets.topic.num.partitions	50	offsets.topic.num.partitions	false
Offset Commit Topic Replication Factor	The replication factor for the offset commit topic. A higher setting (for example, 3 or 4) is recommended in order to ensure higher availability. If the offsets topic is created when there are fewer brokers than the replication factor, then the offsets topic is created with fewer replicas.	offsets.topic.replication.factor	3	offsets.topic.replication.factor	false
Enable Producer Metrics	Enables producer metrics	producer.metrics.enable	false	producer.metrics.enable	false
Default Consumer Quota	Any consumer distinguished by clientId/consumer group will get throttled if it fetches more bytes than this value per-second.	quota.consumer.default		quota.consumer.default	false
Default Producer Quota	Any producer distinguished by clientId will get throttled if it produces more bytes than this value per-second.	quota.producer.default		quota.producer.default	false
Replica Maximum Fetch Size	The maximum number of bytes to fetch for each partition in fetch requests that replicas send to the leader. This value should be larger than message.max.bytes.	replica.fetch.max.bytes	1 MiB	replica.fetch.max.bytes	false
Allowed Replica Message Lag	If a replica falls more than this number of messages behind the leader, the leader removes the follower from the ISR and treats it as dead. This property is deprecated in Kafka 1.4.0; higher versions use only replica.lag.time.max.ms.	replica.lag.max.messages	4000	replica.lag.max.messages	false
Allowed Replica Time Lag	If a follower has not sent any fetch requests, nor has it consumed up to the leader's log end offset during this time, the leader removes the follower from the ISR set.	replica.lag.time.max.ms	10 second(s)	replica.lag.time.max.ms	false
Enable Sentry Privileges Caching	Enables Sentry privilege caching. Only applicable if authorization via Sentry is enabled.	sentry.kafka.caching.enable	true	sentry.kafka.caching.enable	false
Sentry Privileges Cache Refresh Interval	Defines the time interval between updates for the Sentry privileges cache. Any change in role or privilege can take up to the specified time for changes to be reflected in the cache.	sentry.kafka.caching.ttl.ms	30 second(s)	sentry.kafka.caching.ttl.ms	false
Sentry Privileges Cache Maximum Update Failures	If the Sentry privileges cache fails to update for the specified number of times, all authorization requests will be denied.	sentry.kafka.caching.update.failures.count	3	sentry.kafka.caching.update.failures.count	false
Sentry Service	Name of the Sentry service that this Kafka service instance depends on			sentry_service	false
Enable Unclean Leader Election	Enables replicas not in the ISR set to be elected as leader as a last resort, even though doing so might result in data loss.	unclean.leader.election.enable	false	unclean.leader.election.enable	false
ZooKeeper Root	The znode in ZooKeeper used as a root for this Kafka cluster.	zookeeper.chroot		zookeeper.chroot	false
ZooKeeper Session Timeout	If the server fails to send a heartbeat to ZooKeeper within this period of time, it is considered dead. If set to a too low value, ZooKeeper might falsely consider a server dead. If set to a too high value, ZooKeeper might take too long to recognize a dead server.	zookeeper.session.timeout.ms	6 second(s)	zookeeper.session.timeout.ms	false
ZooKeeper Service	Name of the ZooKeeper service that this Kafka service instance depends on			zookeeper_service	true
