2839f4688a app/vmselect/promql: fix panic on sum(aggr_over_time(...)) with incorrect number of args 2020-01-15 16:26:09 +02:00

8b14572f70 app/vmselect/promql: add hoeffding_bound_upper(phi, m[d]) and hoeffding_bound_lower(phi, m[d]) functions
These functions can be used for calculating Hoeffding bounds
for `m` over `d` time range and for the given `phi` in the range `[0..1]`.

46bfdbe6cf app/vmselect/promql: do not take into account the previous point before time window in square brackets for min_over_time, max_over_time, rollup_first and rollup_last functions
This makes the behaviour for these functions similar to Prometheus when processing broken time series with irregular data points
like `gitlab_runner_jobs`. See https://gitlab.com/gitlab-org/gitlab-exporter/issues/50 for details.

4f0a645f77 vendor: update github.com/valyala/fastjson from v1.4.2 to v1.4.5
This should fix parsing Inf values in `/api/v1/import`. The previous attempt to fix this in VictoriaMetrics v1.32.1 was unsuccessful.

164278151f app/vmselect/promql: add aggr_over_time(("aggr_func1", "aggr_func2", ...), m[d]) function
This function can be used for simultaneous calculating of multiple `aggr_func*` functions
that accept range vector. For example, `aggr_over_time(("min_over_time", "max_over_time"), m[d])`
would calculate `min_over_time` and `max_over_time` for `m[d]`.

c4632faa9d app/vmselect/promql: add tmin_over_time(m[d]) and tmax_over_time(m[d]) functions

f358fb72d1 app/{vmbackup,vmrestore}: add backup complete file to backup when it is complete and check for this file before restoring from backup
This should prevent from restoring from incomplete backups.

Add `-skipBackupCompleteCheck` command-line flag to `vmrestore` in order to be able restoring from old backups without `backup complete` file.

0455c03cb9 app/vmselect/promql: properly calculate rate on the first data point
It is calculated as `value / scrape_interval`, since the value was missing on the previous scrape,
i.e. we can assume its value was 0 at this time.

- `topk_max(k, q)` - returns top K time series with the max maximums on the given time range
- `topk_avg(k, q)` - returns top K time series with the max averages on the given time range
- `topk_median(k, q)` - returns top K time series with the max medians on the given time range
- `bottomk_min(k, q)` - returns bottom K time series with the min minimums on the given time range
- `bottomk_max(k, q)` - returns bottom K time series with the min maximums on the given time range
- `bottomk_avg(k, q)` - returns bottom K time series with the min averages on the given time range

20812008a7 lib/storage: remove metricID with missing metricID->metricName entry
The metricID->metricName entry can be missing in the indexdb after unclean shutdown
when only a part of entries for new time series is written into indexdb.

Recover from such a situation by removing the broken metricID. New metricID
will be automatically created for time series with the given metricName
when new data point will arive to it.
