app/vmselect/netstorage: cache canonical MetricName for time series returned from the storage 
This reduces memory allocations for repeated queries, which return (almost) the same set of time series.

all: use metricsql.CompileRegexp instead of regexp.Compile for compiling regexps used in graphite queries 
This should speed up repeated queries, since metricsql.CompileRegexp returns regexps from the cache
on subsequent calls for the same input regexp.

app/vmselect/netstorage: consistently select the sample with the biggest value out of samples with identical timestamps 
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3333

This fix is based on https://github.com/VictoriaMetrics/VictoriaMetrics/pull/3620 ,
but doesn't slow down the common case with merging replicated data blocks so significantly.

all: small improvements in error messages and command-line flag descriptions related to concurrency limiters 2023-01-07 00:12:24 -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.

lib/vmselectapi: limit the number of concurrently executed requests 
This should prevent from out of memory errors when big number of vmselect
nodes send many concurrent requests to vmstorage

The limit can be controlled at vmstorage via the following command-line flags:
- search.maxConcurrentRequests
- search.maxQueueDuration

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)

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).
