dsetool insights_filters

Configures filters to include and exclude specific metrics for DSE Metrics Collector.

By default, the following metrics are always excluded:

  • Thread Per Core (TPC) metrics at each core level

  • Keyspace level metrics

  • DSE internal table metrics (except system_auth, paxos, and batchlog metrics)

Use a regular expression (regex) to specify which metrics to include or exclude from the filter.

Syntax conventions
Syntax conventions Description

UPPERCASE

Literal keyword.

Lowercase

Not literal.

Italics

Variable value. Replace with a valid option or user-defined value.

[ ]

Optional. Square brackets ( [ ] ) surround optional command arguments. Do not type the square brackets.

( )

Group. Parentheses ( ( ) ) identify a group to choose from. Do not type the parentheses.

|

Or. A vertical bar ( | ) separates alternative elements. Type any one of the elements. Do not type the vertical bar.

...

Repeatable. An ellipsis ( ... ) indicates that you can repeat the syntax element as often as required.

'Literal string'

Single quotation ( ' ) marks must surround literal strings in CQL statements. Use single quotation marks to preserve upper case.

{ key:value }

Map collection. Braces ( { } ) enclose map collections or key value pairs. A colon separates the key and the value.

<datatype1,datatype2>

Set, list, map, or tuple. Angle brackets ( < > ) enclose data types in a set, list, map, or tuple. Separate the data types with a comma.

cql_statement;

End CQL statement. A semicolon ( ; ) terminates all CQL statements.

[ -- ]

Separate the command line options from the command arguments with two hyphens ( -- ). This syntax is useful when arguments might be mistaken for command line options.

' <schema> …​ </schema> '

Search CQL only: Single quotation marks ( ' ) surround an entire XML schema declaration.

@xml_entity='xml_entity_type'

Search CQL only: Identify the entity and literal value to overwrite the XML element in the schema and solrconfig files.

--show_filters

Prints the current filters for DSE Metrics Collector.

--remove_all_filters

Remove all metrics filters for DSE Metrics Collector.

--add --global | --insights_only regex

Include metrics that match this regular expression and apply the filter with scope of --global or --insights_only.

--deny --global | --insights_only regex

Exclude metrics that match this regular expression and apply the filter with scope of --global or --insights_only.

--global

Metrics filter scope includes metrics reported locally and insights data files.

--insights_only

Limit metrics filter scope to insights data files only. Appropriate for diagnostic use.

Example filters

Show all active filters

dsetool insights_filters --show_filters

Remove all active filters

dsetool insights_filters --remove_all_filters

Add a global filter to deny all metrics for a specific keyspace

Add a global filter to deny all metrics matching KeyspaceMetrics

dsetool insights_filters --add --global --deny .+KeyspaceMetrics.+

Remove a global filter to allow metrics for a specific keyspace that has an existing deny filter

dsetool insights_filters --remove --global --deny "org\\.apache\\.cassandra\\.metrics\\.(keyspace_name|table_name).*(keyspace_name).*"
