Rules to Extract Events from Log Files	This file contains the rules which govern how log messages are turned into events by the custom log4j appender that this role loads. It is in JSON format, and is composed of a list of rules. Every log message is evaluated against each of these rules in turn to decide whether or not to send an event for that message. Each rule has some or all of the following fields: alert - whether or not events generated from this rule should be promoted to alerts. A value of "true" will cause alerts to be generated. If not specified, the default is "false". rate (mandatory) - the maximum number of log messages matching this rule that may be sent as events every minute. If more than rate matching log messages are received in a single minute, the extra messages are ignored. If rate is less than 0, the number of messages per minute is unlimited. periodminutes - the number of minutes during which the publisher will only publish rate events or fewer. If not specified, the default is one minute threshold - apply this rule only to messages with this log4j severity level or above. An example is "WARN" for warning level messages or higher. content - match only those messages whose contents match this regular expression. exceptiontype - match only those messages which are part of an exception message. The exception type must match this regular expression. Example:{"alert": false, "rate": 10, "exceptiontype": "java.lang.StringIndexOutOfBoundsException"}This rule will send events to Cloudera Manager for every StringIndexOutOfBoundsException, up to a maximum of 10 every minute.		version: 0, rules: [ alert: false, rate: 1, periodminutes: 1, threshold:FATAL, alert: false, rate: 1, periodminutes: 2, exceptiontype: .*, alert: false, rate: 1, periodminutes: 1, threshold:WARN ]	log_event_whitelist	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.

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 will not be evaluated. For example, here is a JSON formatted trigger configured for a DataNode that 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"}]Consult the trigger rules documentation for more details on how to write triggers using tsquery.The JSON format is evolving and may change in the future and as a result backward compatibility is not guaranteed between releases at this time.

Time-Series Storage	The approximate amount of disk space dedicated to storing time series and health data. Once the store has reached its maximum size older data will be deleted to make room for newer data. The disk usage is approximate because we only begin deleting data once we've reached the limit. Note that Cloudera Manager stores time-series data at a number of different data granularities, and these granularities have different effective retention periods. Specifically, Cloudera Manager stores metric data as both raw data points and ten-minutely, hourly, six-hourly, daily, and weekly summary data points. Raw data consumes the bulk of the allocated storage space, weekly summaries the least. As such, raw data is retained for the shortest amount of time, while weekly summary points are unlikely to ever be deleted.

Each rule has some or all of the following fields: alert - whether or not events generated from this rule should be promoted to alerts. A value of "true" will cause alerts to be generated. If not specified, the default is "false". rate (mandatory) - the maximum number of log messages matching this rule that may be sent as events every minute. If more than rate matching log messages are received in a single minute, the extra messages are ignored. If rate is less than 0, the number of messages per minute is unlimited. periodminutes - the number of minutes during which the publisher will only publish rate events or fewer. If not specified, the default is one minute threshold - apply this rule only to messages with this log4j severity level or above.

Note that Cloudera Manager stores time-series data at a number of different data granularities, and these granularities have different effective retention periods. Specifically, Cloudera Manager stores metric data as both raw data points and ten-minutely, hourly, six-hourly, daily, and weekly summary data points. Raw data consumes the bulk of the allocated storage space, weekly summaries the least. As such, raw data is retained for the shortest amount of time, while weekly summary points are unlikely to ever be deleted.

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 B to specify no limit. By default processes not managed by Cloudera Manager will have no limit.	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 B to specify no limit. By default processes not managed by Cloudera Manager will have no limit.	memory.soft_limit_in_bytes	-1 MiB	rm_memory_soft_limit	true

Stacks Collection Frequency	The frequency with which stacks will be collected.	stacks_collection_frequency	5.0 second(s)	stacks_collection_frequency	false
Stacks Collection Method	The method that will be 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

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 all of 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 will not be evaluated. For example, here is a JSON formatted trigger that 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"}]Consult the trigger rules documentation for more details on how to write triggers using tsquery.The JSON format is evolving and may change in the future and as a result backward compatibility is not guaranteed between releases at this time.
