Specifies the squid domain for built-in system metrics.
Optional
fillIf there is no data in the specified region this value will be used to fill the gap. Default: null.
Aggregation functions that maps multiple points per point region to a single point value.
Optional
groupList of ordered tag names for a 'GROUP BY'.
Name of the built-in Squid metric to query.
Optional
noSpecifies what result will be returned if there were no records found in the database. In this case the 'resultGroups' array will be empty (default), or can be filled with a default values if 'return-result-group-with-default-values' is specified. The generated result group will have 'tagValues' set to empty strings.
May be useful to get a ready-to-render array with no additional post-processing required.
Note: 'tagDomains' can provide similar functionality when set of tag values is defined: multiple result groups will be filled with default values. There is no need to use this option if 'tagDomains' is used.
Default: 'return-no-result-groups'
Optional
orderThe results will be ordered by the specified tags (ORDER BY).
End of the queried interval. Must be an integer value.
Start of the queried interval. Must be an integer value.
Optional
pointSpecifies the alignment of the per-point interval. Default: 'align-by-start-time'
Optional
pointTime interval per point. Must be less than periodEndSeconds - periodStartSeconds. Set to 0 or keep undefined to have only 1 value in the result.
Optional
tagA mapping of known tag values that must be present in the response groups.
This ensures that the result will include groups for all specified tag values, even if there is no data for some values in the database.
Example: Consider a tag 'isError' with two possible values: '0' and '1'.
When 'tagDomains' contains {'isError': ['0', '1']}
, the result will include
groups for both 'isError: 0' and 'isError: 1'. If the database lacks data for
'isError: 1', the points in this group will be set to 'fillValue' (default is 'null').
The tags in the new groups will be copied from the existing resultGroups, along with one of the tag domain values.
Optional
tagTag filters. TODO: add operations to exclude tags: !=, !contains...
