Fatih Arslan 362e44501a promql: fix printing annotations of an *AlertStmt
Currently the printer doesn't print the annotations of an `*AlertStmt`
declaration. I've added a test case as well, which fails for the current
master.

beorn7 5408666387 Correctly stringify GROUP_x modifiers without labels
Since rule evaluations work via String(), this fixes evaluation of
rules containing GROUP_x modifiers without labels. This change is the
minimal bugfix (so that we can release a fixed version without
risk). It does not intend to implement any additional features (like
allowing `GROUP_LEFT()` or `ON()` or even `ON` - see discussion in
https://github.com/prometheus/prometheus/issues/1597 ).

Brian Brazil 7201c010c4 Rename On to MatchingLabels 2016-04-26 14:28:36 +01:00
Brian Brazil 1d08c4fef0 Add 'ignoring' as modifier for binops.
Where 'on' uses the given labels to match,
'ignoring' uses all other labels to match.

group_left/right is not supported yet.

Julius Volz 6ac39700ea Fix missing printed keep_common without grouping. 2016-04-15 19:48:17 +02:00
Brian Brazil 9d0112d7cf Add without aggregator modifier.
This has the advantage that the user doesn't need
to list all labels they want to keep (as with "by")
but without having to worry about inconsistent labels
as when there's only one time series (as with "keeping_common").

Almost all aggregation should use this rather than the existing
two options as it's much less error prone and easier to maintain
due to not having to always add in "job" plus whatever other common
job-level labels you have like "region".

beorn7 a7408bfb47 Unify duration parsing
It's actually happening in several places (and for flags, we use the
standard Go time.Duration...). This at least reduces all our
home-grown parsing to one place (in model).

Julius Volz 5e2d1c1464 Deprecate keeping_extra, rename it to keep_common.
`keep_common` is more in line with the function name
`drop_common_labels()` terminology-wise, and also more in line with
`group_left`/`group_right` (no `...ing` verb suffix).

We could also go the full way and call it `keep_common_labels`. That
would have the benefit of being even more consistent with the function
`drop_common_labels()` and would be more explanatory, but it also seems
quite long.

Fabian Reinartz 5602328c7c Refactor query evaluation.
This copies the evaluation logic from the current rules/ package.
The new engine handles the execution process from query string to final result.
It provides query timeout and cancellation and general flexibility for
future changes.

functions.go: Add evaluation implementation. Slight changes to in/out data but
	not to the processing logic.
quantile.go: No changes.
analyzer.go: No changes.
engine.go: Actually new part. Mainly consists of evaluation methods
	which were not changed.
setup_test.go: Copy of rules/helpers_test.go to setup test storage.
promql_test.go: Copy of rules/rules_test.go.

Fabian Reinartz 32b7595c47 Create promql package with lexer/parser.
This commit creates a (so far unused) package. It contains the a custom
lexer/parser for the query language.

ast.go: New AST that interacts well with the parser.
lex.go: Custom lexer (new).
lex_test.go: Lexer tests (new).
parse.go: Custom parser (new).
parse_test.go: Parser tests (new).
functions.go: Changed function type, dummies for parser testing (barely changed/dummies).
printer.go: Adapted from rules/ and adjusted to new AST (mostly unchanged, few additions).
