v1.49.0 Changes
December 05, 2020๐ Changes since v1.48.0
๐ FEATURE: optimize Consul service discovery speed when discovering big number of services. See #574
FEATURE: add
label_uppercase(q, label1, ... labelN)
andlabel_lowercase(q, label1, ... labelN)
function to MetricsQL for uppercasing and lowercasing values for the given labels. See #936FEATURE: add
count_eq_over_time(m[d], N)
andcount_ne_over_time(m[d], N)
for counting the number of samples form
overd
that (equal / not equal) toN
.๐ FEATURE: do not print usage info for all the command-line flags when incorrect command-line flag is passed. Previously it could be hard reading the error message about incorrect command-line flag because of too big usage info for all the flags.
๐ FEATURE: upgrade Go builder from v1.15.5 to v1.15.6 . This fixes issues found in Go since v1.15.5.
๐ BUGFIX: properly parse timestamps in OpenMetrics format - they are exposed as floating-point number in seconds instead of integer milliseconds unlike in Prometheus exposition format. See the docs.
๐ BUGFIX: return
nan
fora >bool b
query whena
equals tonan
like Prometheus does. Previously0
was returned in this case. This applies to any comparison operation withbool
modifier. See these docs for details.๐ BUGFIX: properly parse hex numbers in MetricsQL. Previously hex numbers with non-decimal digits such as
0x3b
couldn't be parsed.BUGFIX: handle
time() cmp_op metric
like Prometheus does - i.e. returnmetric
value ifcmp_op
comparison is true. Previouslytime()
value was returned.BUGFIX: return
nan
forminute(m)
query whenm
equals tonan
like Prometheus does. This applies to all the time-related functions such asday_of_month
,day_of_week
,days_in_month
,hour
,month
andyear

v1.48.0 Changes
November 26, 2020๐ Changes since v1.47.0
๐ FEATURE: added Snap package for single-node VictoriaMetrics. This simplifies installation under Ubuntu to a single command:
snap install victoriametrics
๐ FEATURE: vmselect: add
-replicationFactor
command-line flag for reducing query duration when replication is enabled and a part of vmstorage nodes are temporarily slow and/or temporarily unavailable. See #711FEATURE: vminsert: export
vm_rpc_vmstorage_is_reachable
metric, which can be used for monitoring reachability of vmstorage nodes from vminsert nodes.FEATURE: vmagent: add Netflix Eureka service discovery (aka eureka_sd_config). See #851
FEATURE: add
filters
option todockerswarm_sd_config
like Prometheus did in v2.23.0 - see prometheus/prometheus#8074FEATURE: expose
__meta_ec2_ipv6_addresses
label forec2_sd_config
like Prometheus will do in the next release.๐ FEATURE: add
-loggerWarnsPerSecondLimit
command-line flag for rate limiting of WARN messages in logs. See #905๐ FEATURE: apply
loggerErrorsPerSecondLimit
and-loggerWarnsPerSecondLimit
rate limit per caller. I.e. log messages are suppressed if the same caller logs the same message at the rate exceeding the given limit. See #905 (comment)๐ FEATURE: add remoteAddr to slow query log in order to simplify identifying the client that sends slow queries to VictoriaMetrics. Slow query logging is controlled with
-search.logSlowQueryDuration
command-line flag.๐ FEATURE: add
/tags/delSeries
handler from Graphite Tags API. See https://victoriametrics.github.io/#graphite-tags-api-usage๐ FEATURE: log metric name plus all its labels when the metric timestamp is out of the configured retention. This should simplify detecting the source of metrics with unexpected timestamps.
๐ FEATURE: add
-dryRun
command-line flag to single-node VictoriaMetrics in order to check config file pointed by-promscrape.config
.๐ BUGFIX: properly parse Prometheus metrics with exemplars such as
foo 123 # {bar="baz"} 1
.๐ BUGFIX: properly parse "infinity" values in OpenMetrics format. See #924

v1.47.0 Changes
November 16, 2020๐ Changes since v1.46.0
๐ FEATURE: vmselect: return the original error from
vmstorage
node in query response if-search.denyPartialResponse
is set. See #891๐ FEATURE: vmselect: add
"isPartial":{true|false}
field in JSON output for/api/v1/*
functions from Prometheus querying API."isPartial":true
is set if the response contains partial data because of a part ofvmstorage
nodes were unavailable during query processing.๐ FEATURE: improve performance for
/api/v1/series
,/api/v1/labels
and/api/v1/label/<labelName>/values
on time ranges exceeding one day.๐ FEATURE: vmagent: reduce memory usage when service discovery detects big number of scrape targets and the set of discovered targets changes over time. See #825
๐ FEATURE: vmagent: add
-promscrape.dropOriginalLabels
command-line option, which can be used for reducing memory usage when scraping big number of targets. See #825 (comment) for details.๐ FEATURE: vmalert: explicitly set extra labels to alert entities. See #870
๐ FEATURE: add
-search.treatDotsAsIsInRegexps
command-line flag, which can be used for automatic escaping of dots in regexp label filters used in queries. For example, if-search.treatDotsAsIsInRegexps
is set, then the queryfoo{bar=~"aaa.bb.cc|dd.eee"}
is automatically converted tofoo{bar=~"aaa\\.bb\\.cc|dd\\.eee"}
. This may be useful for querying Graphite metrics.๐ FEATURE: consistently return text-based HTTP responses such as
plain/text
andapplication/json
withcharset=utf-8
. See #897๐ FEATURE: update Go builder from v1.15.4 to v1.15.5. This should fix these issues in Go.
๐ FEATURE: added
/internal/force_flush
http handler for flushing recently ingested data from in-memory buffers to persistent storage. See troubleshooting docs for more details.๐ FEATURE: added Graphite Tags API support. See these docs for details.
๐ BUGFIX: do not return data points in the end of the selected time range for time series ending in the middle of the selected time range. See #887 and #845
๐ BUGFIX: remove spikes at the end of time series gaps for
increase()
ordelta()
functions. See #894๐ BUGFIX: vminsert: properly return HTTP 503 status code when all the vmstorage nodes are unavailable. See #896

v1.46.0 Changes
November 07, 2020๐ Changes since v1.45.0
๐ FEATURE: optimize requests to
/api/v1/labels
and/api/v1/label/<name>/values
whenstart
andend
args are set.๐ FEATURE: reduce memory usage when query touches big number of time series.
FEATURE: vmagent: reduce memory usage when
kubernetes_sd_config
discovers big number of scrape targets (e.g. hundreds of thouthands) and the majority of these targets (99%) are dropped during relabeling. Previously labels for all the dropped targets were displayed at/api/v1/targets
page. Now only up to-promscrape.maxDroppedTargets
such targets are displayed. See #878 for details.๐ FEATURE: vmagent: reduce memory usage when scraping big number of targets with big number of temporary labels starting with
__
. See #825๐ FEATURE: vmagent: add
/ready
HTTP endpoint, which returns 200 OK status code when all the service discovery has been initialized. This may be useful during rolling upgrades. See #875๐ BUGFIX: vmagent: eliminate data race when
-promscrape.streamParse
command-line is set. Previously this mode could result in scraped metrics with garbage labels. See #825 (comment) for details.BUGFIX: properly calculate
topk_*
andbottomk_*
functions from MetricsQL for time series with gaps. See #883How to run VictoriaMetrics

v1.45.0 Changes
November 02, 2020๐ Changes since v1.44.0
๐ FEATURE: allow setting
-retentionPeriod
smaller than one month. I.e.-retentionPeriod=3d
,-retentionPeriod=2w
, etc. is supported now. See #173๐ FEATURE: optimize more cases according to https://utcc.utoronto.ca/~cks/space/blog/sysadmin/PrometheusLabelNonOptimization . Now the following cases are optimized too:
rollup_func(foo{filters}[d]) op bar
->rollup_func(foo{filters}[d]) op bar{filters}
transform_func(foo{filters}) op bar
->transform_func(foo{filters}) op bar{filters}
-
num_or_scalar op foo{filters} op bar
->num_or_scalar op foo{filters} op bar{filters}
๐ FEATURE: improve time series search for queries with multiple label filters. I.e.
foo{label1="value", label2=~"regexp"}
. See #781๐ FEATURE: vmagent: add
stream parse
mode. This mode allows reducing memory usage when individual scrape targets expose tens of millions of metrics. For example, during scraping Prometheus in federation mode. See-promscrape.streamParse
command-line option andstream_parse: true
config option forscrape_config
section in-promscrape.config
. See #825 and troubleshooting docs for vmagent.๐ FEATURE: vmalert: add
-dryRun
command-line option for validating the provided config files without the need to startvmalert
service.FEATURE: accept optional third argument of string type at
topk_*
andbottomk_*
functions. This is label name for additional time series to return with the sum of time series outside top/bottom K. See MetricsQL docs for more details.๐ FEATURE: vmagent: expose
/api/v1/targets
page according to the corresponding Prometheus API. See #643๐ BUGFIX: vmagent: properly handle OpenStack endpoint ending with
v3.0
such ashttps://ostack.example.com:5000/v3.0
in the same way as Prometheus does. See #728 (comment)๐ BUGFIX: drop trailing data points for time series with a single raw sample. See #748
๐ BUGFIX: do not drop trailing data points for instant queries to
/api/v1/query
. See #845๐ BUGFIX: vmbackup: fix panic when
-origin
isn't specified. See #856๐ BUGFIX: vmalert: skip automatically added labels on alerts restore. Label
alertgroup
was introduced in this issue and automatically added to generated time series. By mistake, this new label wasn't correctly purged on restore event and affected alert's ID uniqueness. See #870๐ BUGFIX: vmagent: fix panic at scrape error body formating. See #864
๐ BUGFIX: vmagent: add leading missing slash to metrics path like Prometheus does. See #835
๐ BUGFIX: vmagent: drop packet if remote storage returns 4xx status code. This make the behaviour consistent with Prometheus.
๐ See #873๐ BUGFIX: vmagent: properly handle 301 redirects. See #869
