Metric Filter Defines a Metric Filter for this role. Cloudera Manager Agents will not send filtered metrics to the Service Monitor. Define the following fields:
  • Health Test Metric Set - Select this parameter to collect only metrics required for health tests.
  • Default Dashboard Metric Set - Select this parameter to collect only metrics required for the default dashboards. For user-defined charts, you must add the metrics you require for the chart using the Custom Metrics 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. In this example, the JSON looks like this:{ "includeHealthTestMetricSet": true, "filterType": "whitelist", "metrics": ["jvm_heap_used_mb"] }
monitoring_metric_filter false

Process Swap Memory Thresholds The health test thresholds on the swap memory usage of the process. This takes precedence over the host level threshold. Warning: 200 B, Critical: Never process_swap_memory_thresholds false
Role Triggers The configured triggers for this role. 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 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.

Metric Filter Defines a Metric Filter for this role. Cloudera Manager Agents will not send filtered metrics to the Service Monitor. Define the following fields:
  • Health Test Metric Set - Select this parameter to collect only metrics required for health tests.
  • Default Dashboard Metric Set - Select this parameter to collect only metrics required for the default dashboards. For user-defined charts, you must add the metrics you require for the chart using the Custom Metrics parameter.
  • Include/Exclude Custom Metrics - Select Include to specify metrics that should be collected. Select Exclude to specify metrics that should not be collected. 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

Role Triggers The configured triggers for this role. 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 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.

Metric Filter Defines a Metric Filter for this role. Cloudera Manager Agents will not send filtered metrics to the Service Monitor. Define the following fields:
  • Health Test Metric Set - Select this parameter to collect only metrics required for health tests.
  • Default Dashboard Metric Set - Select this parameter to collect only metrics required for the default dashboards. For user-defined charts, you must add the metrics you require for the chart using the Custom Metrics parameter.
  • Include/Exclude Custom Metrics - Select Include to specify metrics that should be collected. Select Exclude to specify metrics that should not be collected. 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. In this example, the JSON looks like this:{ "includeHealthTestMetricSet": true, "filterType": "whitelist", "metrics": ["jvm_heap_used_mb"] }

Process Swap Memory Thresholds The health test thresholds on the swap memory usage of the process. This takes precedence over the host level threshold. Warning: 200 B, Critical: Never process_swap_memory_thresholds false
Role Triggers The configured triggers for this role. 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 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 Audit Collection Enable collection of audit events from the service's roles. navigator.audit.enabled true navigator_audit_enabled false
Audit Event Filter Event filters are defined in a JSON object like the following: { "defaultAction" : ("accept", "discard"), "rules" : [ { "action" : ("accept", "discard"), "fields" : [ { "name" : "fieldName", "match" : "regex" } ] } ] } A filter has a default action and a list of rules, in order of precedence. Each rule defines an action, and a list of fields to match against the audit event. A rule is "accepted" if all the listed field entries match the audit event. At that point, the action declared by the rule is taken. If no rules match the event, the default action is taken. Actions default to "accept" if not defined in the JSON object. The following is the list of fields that can be filtered for Impala events:
  • userName: the user performing the action.
  • ipAddress: the IP from where the request originated.
  • operation: the Impala operation being performed.
  • databaseName: the databaseName for the operation.
  • tableName: the tableName for the operation.
navigator.event.filter navigator_audit_event_filter false
Audit Queue Policy Action to take when the audit event queue is full. Drop the event or shutdown the affected process. navigator.batch.queue_policy DROP navigator_audit_queue_policy false
Audit Event Tracker Configures the rules for event tracking and coalescing. This feature is used to define equivalency between different audit events. When events match, according to a set of configurable parameters, only one entry in the audit list is generated for all the matching events. Tracking works by keeping a reference to events when they first appear, and comparing other incoming events against the "tracked" events according to the rules defined here. Event trackers are defined in a JSON object like the following: { "timeToLive" : [integer], "fields" : [ { "type" : [string], "name" : [string] } ] } Where:
  • timeToLive: maximum amount of time an event will be tracked, in milliseconds. Must be provided. This defines how long, since it's first seen, an event will be tracked. A value of 0 disables tracking.
  • fields: list of fields to compare when matching events against tracked events.
Each field has an evaluator type associated with it. The evaluator defines how the field data is to be compared. The following evaluators are available:
  • value: uses the field value for comparison.
  • userName: treats the field value as a userName, and ignores any host-specific data. This is useful for environment using Kerberos, so that only the principal name and realm are compared.
The following is the list of fields that can be used to compare Impala events:
  • operation: the Impala operation being performed.
  • username: the user performing the action.
  • ipAddress: the IP from where the request originated.
  • allowed: whether the operation was allowed or denied.
  • databaseName: the database affected by the operation.
  • tableName: the table affected by the operation.
  • objectType: the type of object affected by the operation.
  • privilege: the privilege associated with the operation.

Impala Query Aggregates Controls the aggregate metrics generated for Impala queries. The structure is a JSON list of the attributes to aggregate and the entities to aggregate to. For example, if the attributeName is 'hdfs_bytes_read' and the aggregationTargets is ['USER'] then the Service Monitor will create the metric 'impala_query_hdfs_bytes_read_rate' and, every ten minutes, will record the total hdfs bytes read for each user across all their Impala queries. By default it will also record the number of queries issues ('num_impala_queries_rate') for both users and pool. For a full list of the supported attributes see the Impala search page. Note that the valid aggregation targets are USER, YARN_POOL, and IMPALA (the service), and that these aggregate metrics can be viewed on both the reports and charts search pages. [ attributeName: hdfs_bytes_read, aggregationTargets: [USER, IMPALA_POOL_USER, IMPALA_POOL, IMPALA, CLUSTER] , attributeName: hdfs_bytes_written, aggregationTargets: [USER, IMPALA_POOL_USER, IMPALA_POOL, IMPALA, CLUSTER] , attributeName: thread_cpu_time, aggregationTargets: [USER, IMPALA_POOL_USER, IMPALA_POOL, IMPALA, CLUSTER] , attributeName: bytes_streamed, aggregationTargets: [USER, IMPALA_POOL_USER, IMPALA_POOL, IMPALA, CLUSTER] , attributeName: cm_cpu_milliseconds, aggregationTargets: [USER, IMPALA_POOL_USER, IMPALA_POOL, IMPALA, CLUSTER] , attributeName: query_duration, aggregationTargets: [USER, IMPALA_POOL_USER, IMPALA_POOL, IMPALA, CLUSTER] , attributeName: admission_wait, aggregationTargets: [USER, IMPALA_POOL_USER, IMPALA_POOL, IMPALA, CLUSTER] , attributeName: memory_accrual, aggregationTargets: [USER, IMPALA_POOL_USER, IMPALA_POOL, IMPALA, CLUSTER] , attributeName: thread_cpu_time, aggregationTargets: [USER, IMPALA_POOL_USER, IMPALA_POOL, IMPALA, CLUSTER] , attributeName: memory_spilled, aggregationTargets: [USER, IMPALA_POOL_USER, IMPALA_POOL, IMPALA, CLUSTER] ] impala_query_aggregates false
Impala StateStore Role Health Test When computing the overall IMPALA health, consider Impala StateStore's health true impala_statestore_health_enabled 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.

LDAP URL The URL of the LDAP Server. The URL must be prefixed with ldap:// or ldaps:// . The URL can optionally specify a custom port if necessary, but by default the ldap:// will connect to port 389, and the ldaps:// will connect to port 636. Note that passwords will be in the clear if ldap:// is used, and by fall 2020 Active directory servers will no longer allow non LDAPS connections to bind to AD hosts with LDAP signing enabled. See microsoft knowledge document 935834 for more information. ldap_uri impala_ldap_uri false
impala TLS/SSL Client Trust Store File The location on disk of the trust store, in .jks format, used to confirm the authenticity of TLS/SSL servers that impala might connect to. This is used when impala is the client in a TLS/SSL connection. This trust store must contain the certificate(s) used to sign the service(s) connected to. If this parameter is not provided, the default list of well-known certificate authorities is used instead. impala_truststore_file false
impala TLS/SSL Client Trust Store Password The password for the impala TLS/SSL Certificate Trust Store File. This password is not required to access the trust store; this field can be left blank.

LDAP BaseDN This parameter is useful when authenticating against a non-Active Directory server, such as OpenLDAP. When set, this parameter is used to convert the username into the LDAP Distinguished Name (DN), so that the resulting DN looks like uid=username,this parameter. For example, if this parameter is set to "ou=People,dc=cloudera,dc=com", and the username passed in is "mike", the resulting authentication passed to the LDAP server look like "uid=mike,ou=People,dc=cloudera,dc=com". This parameter is mutually exclusive with Active Directory Domain. ldap_baseDN ldap_baseDN false
LDAP Pattern When set, this parameter allows arbitrary mapping from usernames into a Distinguished Name (DN). The string specified must have a placeholder named "#UID" inside it, and that #UID is replaced with the username. For example, you could mimic the behavior of LDAP BaseDN by specifying "uid=#UID,ou=People,dc=cloudera,dc=com". When the username of "mike" comes in, it replaces the #UID and the result is "uid=mike,ou=People,dc=cloudera,dc=com". This option should be used when more control over the DN is needed. This parameter is mutually exclusive with LDAP Domain and LDAP BaseDN. ldap_bind_pattern ldap_bind_pattern false
Active Directory Domain Use this field for Active Directory configurations only, when combined with a simple username value in the "LDAP Bind User Distinguished Name" field, it will result in a UPM of user@example.com used for search/bind operations for authenticated user lookups. ldap_domain ldap_domain false

Impala TLS/SSL CA Certificate The location on disk of the certificate, in PEM format, used to confirm the authenticity of SSL/TLS servers that the Impala daemons might connect to. Because the Impala daemons connect to each other, this should also include the CA certificate used to sign all the SSL/TLS Certificates. Without this parameter, SSL/TLS between Impala daemons will not be enabled. ssl_client_ca_certificate ssl_client_ca_certificate false
Impala TLS/SSL Server Private Key File (PEM Format) The path to the TLS/SSL file containing the private key used for TLS/SSL. Used when Impala is acting as a TLS/SSL server. The certificate file must be in PEM format. ssl_private_key ssl_private_key false
