Enable Audit Collection Enable collection of audit events from the service's roles. false 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 Solr events:
  • operation: the Solr 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.
 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 Solr events:
  • operation: the Solr 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.

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 followig 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.

Active Directory Domain This parameter is useful when authenticating against an Active Directory server. This value is appended to all usernames before authenticating against AD. For example, if this parameter is set to "my.domain.com", and the user authenticating is "mike", then "mike@my.domain.com" is passed to AD. If this field is unset, the username remains unaltered before being passed to AD. ldap_domain false

Solr TLS/SSL Server JKS Keystore File Location The path to the TLS/SSL keystore file containing the server certificate and private key used for TLS/SSL. Used when Solr is acting as a TLS/SSL server. The keystore must be in JKS format. solr_https_keystore_file false
Solr TLS/SSL Server JKS Keystore File Password The password for the Solr JKS keystore file. solr.jetty.keystore.password solr_https_keystore_password false
Solr 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 Solr might connect to. This is used when Solr 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. solr_https_truststore_file false
Solr TLS/SSL Client Trust Store Password The password for the Solr TLS/SSL Certificate Trust Store File. This password is not required to access the trust store; this field can be left blank. This password provides optional integrity checking of the file. The contents of trust stores are certificates, and certificates are public information. solr.jetty.truststore.password solr_https_truststore_password false
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. solr_ldap_basedn false
Enable LDAP TLS If true, attempts to establish a TLS (Transport Layer Security) connection with an LDAP server that was specified with ldap://. Not required when using an LDAP URL with prefix ldaps://, because that already specifies TLS. This option is also known as "Use StartTLS". false solr_ldap_enable_starttls false
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, for example: ldaps://ldap_server.example.com:1636. Note that usernames and passwords will be transmitted in the clear unless either an ldaps:// URL is used, or "Enable LDAP TLS" is turned on (where available). Also note that encryption must be in use between the client and this service for the same reason.For more detail on the LDAP URL format, see RFC 2255 . A space-separated list of URLs can be entered; in this case the URLs will each be tried in turn until one replies. solr_ldap_uri false
Solr Secure Authentication Choose the authentication mechanism used by Solr. simple solr_security_authentication false
Enable TLS/SSL for Solr Encrypt communication between clients and Solr using Transport Layer Security (TLS) (formerly known as Secure Socket Layer (SSL)). Additional manual steps must be performed. false solr_use_ssl false

Cgroup CPU Shares Number of CPU shares to assign to this role. The greater the number of shares, the larger the share of the host's CPUs that will be given to this role when the host experiences CPU contention. Must be between 2 and 262144. Defaults to 1024 for processes not managed by Cloudera Manager. cpu.shares 1024 rm_cpu_shares true
Cgroup I/O Weight Weight for the read I/O requests issued by this role. The greater the weight, the higher the priority of the requests when the host experiences I/O contention. Must be between 100 and 1000. Defaults to 1000 for processes not managed by Cloudera Manager. blkio.weight 500 rm_io_weight true
Cgroup Memory Hard Limit Hard memory limit to assign to this role, enforced by the Linux kernel. When the limit is reached, the kernel will reclaim pages charged to the process. If reclaiming fails, the kernel may kill the process. Both anonymous as well as page cache pages contribute to the limit. Use a value of -1 to specify no limit. By default processes not managed by Cloudera Manager will have no limit. If the value is -1, Cloudera Manager will not monitor Cgroup memory usage therefore some of the charts will show 'No Data' memory.limit_in_bytes -1 MiB rm_memory_hard_limit true
Cgroup Memory Soft Limit Soft memory limit to assign to this role, enforced by the Linux kernel. When the limit is reached, the kernel will reclaim pages charged to the process if and only if the host is facing memory pressure. If reclaiming fails, the kernel may kill the process. Both anonymous as well as page cache pages contribute to the limit. Use a value of -1 to specify no limit. By default processes not managed by Cloudera Manager will have no limit. If the value is -1, Cloudera Manager will not monitor Cgroup memory usage therefore some of the charts will show 'No Data' memory.soft_limit_in_bytes -1 MiB rm_memory_soft_limit true
HDFS Block Cache Blocks per Slab Number of blocks per cache slab. The size of the cache is 8 KB (the block size) times the number of blocks per slab times the number of slabs. solr.hdfs.blockcache.blocksperbank 16384 solr_hdfs_blockcache_blocksperbank true
HDFS Block Cache Off-Heap Memory Use off-heap memory when caching HDFS blocks in Solr. solr.hdfs.blockcache.direct.memory.allocation true solr_hdfs_blockcache_direct_memory_allocation true
HDFS Block Cache Enable caching of HDFS blocks in Solr. There is one block cache per Solr collection. configured to use off-heap memory, Maximum Off-Heap Memory must be set high enough to account for all block caches. solr.hdfs.blockcache.enabled true solr_hdfs_blockcache_enabled true
HDFS Block Cache Number of Slabs Number of slabs per block cache. The size of the cache is 8 KB (the block size) times the number of blocks per slab times the number of slabs. solr.hdfs.blockcache.slab.count 1 solr_hdfs_blockcache_slab_count true
Java Direct Memory Size of Solr Server in Bytes Maximum amount of off-heap memory in bytes that may be allocated by the Java process. Passed to Java -XX:MaxDirectMemorySize. If unset, defaults to the size of the heap. 1 GiB solr_java_direct_memory_size false

Stacks Collection Data Retention The amount of stacks data that is retained. After the retention limit is reached, the oldest data is deleted. stacks_collection_data_retention 100 MiB stacks_collection_data_retention false
Stacks Collection Directory The directory in which stacks logs are placed. If not set, stacks are logged into a stacks subdirectory of the role's log directory. stacks_collection_directory stacks_collection_directory false
Stacks Collection Enabled Whether or not periodic stacks collection is enabled. stacks_collection_enabled false stacks_collection_enabled true
Stacks Collection Frequency The frequency with which stacks are collected. stacks_collection_frequency 5.0 second(s) stacks_collection_frequency false
Stacks Collection Method The method used to collect stacks. The jstack option involves periodically running the jstack command against the role's daemon process. The servlet method is available for those roles that have an HTTP server endpoint exposing the current stacks traces of all threads. When the servlet method is selected, that HTTP endpoint is periodically scraped. stacks_collection_method jstack stacks_collection_method false
