Filter Methods¶
IndexList¶
-
IndexList.
filter_allocated
(key=None, value=None, allocation_type='require', exclude=True) Match indices that have the routing allocation rule of key=value from indices
Parameters: - key – The allocation attribute to check for
- value – The value to check for
- allocation_type – Type of allocation to apply
- exclude – If exclude is True, this filter will remove matching indices from indices. If exclude is False, then only matching indices will be kept in indices. Default is True
-
IndexList.
filter_by_age
(source='name', direction=None, timestring=None, unit=None, unit_count=None, field=None, stats_result='min_value', epoch=None, exclude=False, unit_count_pattern=False) Match indices by relative age calculations.
Parameters: - source – Source of index age. Can be one of ‘name’, ‘creation_date’, or ‘field_stats’
- direction – Time to filter, either
older
oryounger
- timestring – An strftime string to match the datestamp in an index
name. Only used for index filtering by
name
. - unit – One of
seconds
,minutes
,hours
,days
,weeks
,months
, oryears
. - unit_count – The number of
unit
(s).unit_count
*unit
will be calculated out to the relative number of seconds. - unit_count_pattern – A regular expression whose capture group identifies
the value for
unit_count
. - field – A timestamp field name. Only used for
field_stats
based calculations. - stats_result – Either min_value or max_value. Only used in conjunction with source`=``field_stats` to choose whether to reference the minimum or maximum result value.
- epoch – An epoch timestamp used in conjunction with
unit
andunit_count
to establish a point of reference for calculations. If not provided, the current time will be used. - exclude – If exclude is True, this filter will remove matching indices from indices. If exclude is False, then only matching indices will be kept in indices. Default is False
-
IndexList.
filter_by_regex
(kind=None, value=None, exclude=False) Match indices by regular expression (pattern).
Parameters: - kind – Can be one of:
suffix
,prefix
,regex
, ortimestring
. This option defines what kind of filter you will be building. - value – Depends on kind. It is the strftime string if kind is
timestring
. It’s used to build the regular expression for other kinds. - exclude – If exclude is True, this filter will remove matching indices from indices. If exclude is False, then only matching indices will be kept in indices. Default is False
- kind – Can be one of:
-
IndexList.
filter_by_space
(disk_space=None, reverse=True, use_age=False, source='creation_date', timestring=None, field=None, stats_result='min_value', exclude=False) Remove indices from the actionable list based on space consumed, sorted reverse-alphabetically by default. If you set reverse to False, it will be sorted alphabetically.
The default is usually what you will want. If only one kind of index is provided–for example, indices matching
logstash-%Y.%m.%d
–then reverse alphabetical sorting will mean the oldest will remain in the list, because lower numbers in the dates mean older indices.By setting reverse to False, then
index3
will be deleted beforeindex2
, which will be deleted beforeindex1
use_age allows ordering indices by age. Age is determined by the index creation date by default, but you can specify an source of
name
,max_value
, ormin_value
. Thename
source requires the timestring argument.Parameters: - disk_space – Filter indices over n gigabytes
- reverse – The filtering direction. (default: True). Ignored if use_age is True
- use_age – Sort indices by age.
source
is required in this case. - source – Source of index age. Can be one of
name
,creation_date
, orfield_stats
. Default:creation_date
- timestring – An strftime string to match the datestamp in an index
name. Only used if source
name
is selected. - field – A timestamp field name. Only used if source
field_stats
is selected. - stats_result – Either min_value or max_value. Only used if
source
field_stats
is selected. It determines whether to reference the minimum or maximum value of field in each index. - exclude – If exclude is True, this filter will remove matching indices from indices. If exclude is False, then only matching indices will be kept in indices. Default is False
-
IndexList.
filter_closed
(exclude=True) Filter out closed indices from indices
Parameters: exclude – If exclude is True, this filter will remove matching indices from indices. If exclude is False, then only matching indices will be kept in indices. Default is True
-
IndexList.
filter_forceMerged
(max_num_segments=None, exclude=True) Match any index which has max_num_segments per shard or fewer in the actionable list.
Parameters: - max_num_segments – Cutoff number of segments per shard.
- exclude – If exclude is True, this filter will remove matching indices from indices. If exclude is False, then only matching indices will be kept in indices. Default is True
-
IndexList.
filter_kibana
(exclude=True) Match any index named
.kibana
,kibana-int
,.marvel-kibana
, or.marvel-es-data
in indices.Parameters: exclude – If exclude is True, this filter will remove matching indices from indices. If exclude is False, then only matching indices will be kept in indices. Default is True
-
IndexList.
filter_opened
(exclude=True) Filter out opened indices from indices
Parameters: exclude – If exclude is True, this filter will remove matching indices from indices. If exclude is False, then only matching indices will be kept in indices. Default is True
-
IndexList.
filter_none
()
-
IndexList.
filter_by_alias
(aliases=None, exclude=False) Match indices which are associated with the alias or list of aliases identified by aliases.
An update to Elasticsearch 5.5.0 changes the behavior of this from previous 5.x versions: https://www.elastic.co/guide/en/elasticsearch/reference/5.5/breaking-changes-5.5.html#breaking_55_rest_changes
What this means is that indices must appear in all aliases in list aliases or a 404 error will result, leading to no indices being matched. In older versions, if the index was associated with even one of the aliases in aliases, it would result in a match.
It is unknown if this behavior affects anyone. At the time this was written, no users have been bit by this. The code could be adapted to manually loop if the previous behavior is desired. But if no users complain, this will become the accepted/expected behavior.
Parameters: - aliases (list) – A list of alias names.
- exclude – If exclude is True, this filter will remove matching indices from indices. If exclude is False, then only matching indices will be kept in indices. Default is False
-
IndexList.
filter_by_count
(count=None, reverse=True, use_age=False, source='creation_date', timestring=None, field=None, stats_result='min_value', exclude=True) Remove indices from the actionable list beyond the number count, sorted reverse-alphabetically by default. If you set reverse to False, it will be sorted alphabetically.
The default is usually what you will want. If only one kind of index is provided–for example, indices matching
logstash-%Y.%m.%d
–then reverse alphabetical sorting will mean the oldest will remain in the list, because lower numbers in the dates mean older indices.By setting reverse to False, then
index3
will be deleted beforeindex2
, which will be deleted beforeindex1
use_age allows ordering indices by age. Age is determined by the index creation date by default, but you can specify an source of
name

source
field_stats
is selected. It determines whether to reference the minimum or maximum value of field in each index. - exclude – If exclude is True, this filter will remove matching indices from indices. If exclude is False, then only matching indices will be kept in indices. Default is True
-
