VictoriaMetrics/VictoriaMetrics最新发布版本:v1.101.0(2024-04-26 17:06:08)

Released at 2024-03-01

FEATURE: MetricsQL: propagate label filters via all the label manipulation functions. For example, label_del(some_metric{job="foo"}, "instance") + other_metric{pod="bar"} is now transformed to label_del(some_metric{job="foo",pod="bar"}, "instance") + other_metric{job="foo",pod="bar"}. This should reduce the amounts of time series processed during query execution.
FEATURE: MetricsQL: add count_values_over_time function. See this feature request.
FEATURE: Single-node VictoriaMetrics and vmstorage in VictoriaMetrics cluster: expose vm_last_partition_parts metrics, which show the number of parts in the latest partition. These metrics may help debugging query performance slowdown related to the increased number of parts in the last partition, since usually all the ingested data is written to the last partition and all the queries are performed over the recently ingested data, e.g. the last partition.
FEATURE: Single-node VictoriaMetrics and vmstorage in VictoriaMetrics cluster: expose vm_snapshots metric, which shows the current number of snapshots created via snapshot API.
FEATURE: Single-node VictoriaMetrics and vmselect in VictoriaMetrics cluster: add -search.ignoreExtraFiltersAtLabelsAPI command-line flag, which can be used for reducing load on VictoriaMetrics when /api/v1/labels, /api/v1/label/.../values or /api/v1/series are queried with too broad extra_filters or extra_label, which match many time series. See these docs for details.
FEATURE: Single-node VictoriaMetrics and vmselect in VictoriaMetrics cluster: allow limiting CPU and RAM usage at /api/v1/labels, /api/v1/label/.../values and /api/v1/series on systems with high churn rate via -search.maxLabelsAPIDuration and -search.maxLabelsAPISeries command-line flags. See these docs for details.
FEATURE: vmagent: support reading Amazon CloudWatch metrics in OpenTelemetry format from Amazon Data Firehose.
FEATURE: vmagent: add support for client_id option into kuma_sd_configs in the same way as Prometheus does. See this pull request.
FEATURE: vmagent: add support for enable_compression option in scrape_configs in order to be compatible with Prometheus scrape configs. See this pull request and this feature request. Note that vmagent was always supporting disable_compression option before Prometheus added enable_compression option.
FEATURE: vmctl: support client-side TLS configuration for InfluxDB, Remote Read protocol and OpenTSDB. See this feature request. Thanks to @khushijain21 for pull requests 1, 2, 3.
FEATURE: vmui: preserve WITH templates when clicking the prettify query button at the right side of query input field. See this feature request.
FEATURE: vmui: allow filling gaps on graphs with interpolated lines as Grafana does. See this feature request and this pull request.
FEATURE: vmalert: support filtering by group, rule or labels in vmalert's UI for /groups and /alerts pages. See the pull request by @victoramsantos.
FEATURE: docker-compose: create a separate docker-compose environment for VictoriaLogs installation, including fluentbit and VictoriaLogs Grafana datasource.
FEATURE: vmbackupmanager: wait for up 30 seconds before making a snapshot for backup if vmstorage is temporarily unavailalbe. This should prevent from vmbackupmanager termination in this case. See this feature request.
BUGFIX: downgrade Go builder from 1.22.0 to 1.21.7, since 1.22.0 contains the bug, which can lead to deadlocked HTTP connections to remote storage systems, scrape targets and service discovery endpoints at vmagent. This may result in incorrect service discovery, target scraping and failed sending samples to remote storage.
BUGFIX: all VictoriaMetrics components: return back periodic closing of incoming connections to -httpListenAddr every 2 minutes, which was disabled in v1.98.0 when addressing this issue. See this comment for details on why the periodic closing of incoming connections has been returned back.
BUGFIX: vmagent: accept OpenTelemetry data at /opentelemetry/v1/metrics, since the /v1/metrics suffix is hardcoded at OpenTelemetry protocol specification.
BUGFIX: vmagent: fix possible deadlock when sharding among remote storages is enabled with -remoteWrite.shardByURL command-line flag. Thanks to @penguinlav for the fix for this issue.
BUGFIX: fix the misleading error 0ms is out of allowed range [0 ... when passing step=0 to /api/v1/query or /api/v1/query_range. See this issue.
BUGFIX: Single-node VictoriaMetrics and vmselect in VictoriaMetrics cluster: fixed floating-point error when parsing time in RFC3339 format. See this issue for details.
BUGFIX: vmalert: consistently sort groups by name and filename on /groups page in UI. This should prevent non-deterministic sorting for groups with identical names.
BUGFIX: vmui: fix Popper display issues. See this pull request.
BUGFIX: vmselect: format time with milliseconds precision when __timestamp__:rfc3339 is specified for /api/v1/export/csv API response. See this issue for details.
BUGFIX: MetricsQL: properly construct the destination label in label_join if it is used as source label. See this issue for details.
