40e564eb9c app/vmselect/promql: add range_over_time(m[d]) function for calculating value range for m over d 2020-01-21 19:05:29 +02:00

ecddba30fe app/vminsert/netstorage: increase timeout for pushing data from vminsert to vmstorage by 3x 
Our clients report that the previous timeout could lead to frequent errors when
vmstorage starts background merge for big parts on slow HDD.

9eaa2ab871 app/vmselect/promql: add label_match(q, label, regexp) and label_mismatch(q, label, regexp) functions for filtering out time series with labels matching the given regexp 2020-01-21 15:00:35 +02:00

cbd0452317 app/vminsert: increase default value for -insert.maxQueueDuration from 30s to 60s 
This should help catching up with high ingestion rate after VictoriaMetrics restart.

2084921e64 all: use github.com/klauspost/compress/gzip instead of compress/gzip 
`github.com/klauspost/compress/gzip` is more optimized than `compress/gzip`.
This gives better gzip compression and decompression speeds.

d21cc2d16a app/vmselect/netstorage: limit the maximum size for in-memory buffer for temporary blocks file 
This should reduce memory usage on systems with more than 8GB RAM.

b05f6cf11c app/vmselect: limit the default value for -search.maxConcurrentRequests, so it plays well on systems with more than 16 vCPUs 
A single heavy request can saturate all the available CPUs, so let's limit the number of concurrent requests to lower value.
This will give more chances for executing insert path.

a9f683423c app/{vminsert,vmselect}: improve error messages when VictoriaMetrics cannot handle too high number of concurrent inserts / selects 2020-01-17 16:16:43 +02:00

4b16b7fd11 all: mention command-line flags used for limiting the incoming request size in error messages 
This should improve error logs usability.

ce0b602405 app/vmselect/promql: fix panic on sum(aggr_over_time(...)) with incorrect number of args 2020-01-15 16:26:16 +02:00

bcd3f0c5bd 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]`.

fc01b11ddc app/vmselect/promql: return continuous values for min_over_time and max_over_time when step is smaller than scrape_interval 2020-01-11 12:47:57 +02:00
Aliaksandr Valialkin
16fb128bbc 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.

1c445bf7eb 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.

87a106702b 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]`.

c314d9a219 app/vmselect/promql: add tmin_over_time(m[d]) and tmax_over_time(m[d]) functions 
These functions return timestamp in seconds for the minimum and maximum value for `m` over time range `d`

705af61587 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.

9a1f6848ca app/vmselect/promql: fix results caching for multi-arg rollup functions such as quantile_over_time 
Previosly only a single arg was taken into account, so caching didn't work properly for multi-arg rollup funcs.

3d0c7b095a app/vmselect/promql: use scrapeInterval instead of window in denominator when calculating rate for the first point on the time series

9a2554691c 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.
