app/vmselect/netstorage: do not intern string representation of MetricName for time series received from vmstorage 
It has been appeared that this interning may lead to increased memory usage and increased CPU usage
when vmselect performs queries, which select big number of time series.

vmselect/promql: check for deadline in count_values fn (#3806) 
* vmselect/promql: check for deadline in `count_values` fn

`count_values` could be very slow during the data processing.
Checking for deadline between iterations supposed to reduce
probability of exceeding `search.maxQueryDuration`.

The change also adds a new trace record, which captures the time
spent in aggregation function. Before that, the trace for aggr funcs
could be confusing since it doesn't account for all the places where
time was spent.

metricsql: support optional 2nd argument for rollup functions (#3841) 
* metricsql: support optional 2nd argument for rollup functions

Support optional 2nd argument `min`, `max` or `avg` for rollup functions:
 * rollup
 * rollup_delta
 * rollup_deriv
 * rollup_increase
 * rollup_rate
 * rollup_scrape_interval

 If second argument is passed, then rollup function will return only the selected aggregation type.
 This change can be useful for situations where only one type of rollup calculation is needed.
 For example, `rollup_rate(requests_total[5m], "max")`.

app/vmselect/netstorage: reduce tail latency during query processing 
Previously the selected time series were split evenly among available CPU cores
for further processing - e.g unpacking the data and applying the given rollup
function to the unpacked data.
Some time series could be processed slower than others.
This could result in uneven work distribution among available CPU cores,
e.g. some CPU cores could complete their work sooner than others.
This could slow down query execution.

The new algorithm allows stealing time series to process from other CPU cores
when all the local work is done. This should reduce the maximum time
needed for query execution (aka tail latency).

The new algorithm should also scale better on systems with many CPU cores,
since every CPU processes locally assigned time series without inter-CPU communications.

The inter-CPU communications are used only when all the local work is finished
and the pending work from other CPUs needs to be stealed.

all: small improvements in error messages and command-line flag descriptions related to concurrency limiters 2023-01-07 00:11:44 -08:00

lib/writeconcurrencylimiter: improve the logic behind -maxConcurrentInserts limit 
Previously the -maxConcurrentInserts was limiting the number of established client connections,
which write data to VictoriaMetrics. Some of these connections could be idle.
Such connections do not consume big amounts of CPU and RAM, so there is a little sense in limiting
the number of such connections. So now the -maxConcurrentInserts command-line option
limits the number of concurrently executed insert requests, not including idle connections.

It is recommended removing -maxConcurrentInserts command-line option, since the default value
for this option should work good for most cases.

app/vmui: small usability improvements 
- Show in the line tooltip the number of the query which generates the given line.
  This simplifies comparison of lines generated by multiple queries.

- Show metric name as __name__ label in the line tooltip in the same way as other labels are shown there.
  This makes the label information in the tooltip more consistent.

- Properly quote label values with JSON.stringify(). This prevents from improper formatting
  when label values contain doublequote chars.

- Remove double curly braces artifact at graph legend for lines without names and labels.

- Properly use modifier for regular expressions across the code.

app/vmselect/prometheus: no need manually call queryDuration.UpdateDuration (#3564) 
There is no need to manually call `queryDuration.UpdateDuration(startTime)`, because `defer queryDuration.UpdateDuration(startTime)` is executed at the beginning of the function(L660).

app/vmselect/searchutils: accept partial RFC3339 values at time, start and end query args 
This simplifies manual usage of the APIs. For example, the following query
would return the results over the 2022 year.

  /api/v1/query_range?start=2022&end=2023&step=1d&query=...

This is equivalent to:

  /api/v1/query_range?start=2022-01-01T00:00:00Z&end=2023-01-01T00:00:00Z&step=1d&query=...

- Document the feature at docs/CHANGELOG.md.
- Document the metrics explorer at https://docs.victoriametrics.com/#metrics-explorer .
- Properly set `start` and `end` args for the selected time range
  when performing the request, which returns metric names.
- Improve queries, so they return lower number of lines and labels.
  This should improve metrics' exploration.
- Properly encode label filters and query args before passing them to VictoriaMetrics.
- Various cosmetic fixes.

app/vmselect/promql: do not extend too short lookbehind window for rate() function if it is set explicitly 
Previously too short lookbehind window d for rate(m[d]) could be automatically extended
if it didn't cover at least two raw samples. This was needed in order to guarantee
non-empty results from rate(m[d]) on short time ranges.

Now the lookbehind window isn't extended if it is set explicitly,
since it is expected that the user knows what he is doing.

The lookbehind window continues to be extended when needed if it isn't set explicitly.
For example, in the case of rate(m).
