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

Released at 2024-04-26

FEATURE: MetricsQL: support filtering by multiple numeric constants via q == (C1, ..., CN) and q != (C1, ..., CN) syntax. For example, status_code == (200, 201, 300) returns status_code metrics with any of 200, 201 or 300 values, while status_code != (400, 404, 500) returns status_code metrics with all the values except of 400, 404 and 500.
FEATURE: VictoriaMetrics cluster: add support for fault domain awareness to vmselect. It can be configured to return full responses if up to -globalReplicationFactor - 1 fault domains (aka vmstorage groups) are unavailable. See this feature request and these docs.
FEATURE: all VictoriaMetrics enterprise components: add support for automatic issuing of TLS certificates for HTTPS server at -httpListenAddr via Let's Encrypt service. See these docs and this feature request.
FEATURE: vmsingle: support disable or log implicit conversions for subquery with cmd-line flags -search.disableImplicitConversion and -search.logImplicitConversion. See this feature request.
FEATURE: vmagent: support data replication additionally to sharding among remote storage systems if -remoteWrite.shardByURLReplicas=N command-line flag is set additionally to -remoteWrite.shardByURL command-line flag, where N is desired replication factor. This allows setting up data replication among failure domains when the replication factor is smaller than the number of failure domains. See these docs and this feature request.
FEATURE: vmagent: reduce CPU usage when sharding among remote storage systems is enabled.
FEATURE: vmagent: support DNS SRV addresses in -remoteWrite.url command-line option and in scrape target urls. For example, -remoteWrite.url=http://srv+victoria-metrics/api/v1/write automatically resolves the victoria-metrics DNS SRV to a list of hostnames with TCP ports and then sends the collected metrics to these TCP addresses. See these docs and this feature request.
FEATURE: stream aggregation: allow skipping first N aggregation intervals via cmd-line flag -streamAggr.ignoreFirstIntervals for Single-node VictoriaMetrics or -remoteWrite.streamAggr.ignoreFirstIntervals for vmagent. See more details here.
FEATURE: vmauth: support automatic discovering and load balancing for TCP addresses behind DNS SRV addresses. These addresses can be put inside url_prefix urls in the form http://srv+addr/path, where the addr is the DNS SRV address, which is automatically resolved to hostnames with TCP ports. See these docs for details.
FEATURE: vmauth: support specifying client TLS certificates and TLS ServerName for requests to HTTPS backends. See these docs.
FEATURE: vmauth: support regex matching when routing incoming requests based on HTTP query args via src_query_args option at url_map. See these docs and this feature request.
FEATURE: vmui: optimize auto-suggestion performance for metric names when the database contains big number of unique time series.
FEATURE: vmui: in the Select component, user-entered values are now preserved on blur if they match options in the list.
FEATURE: vmui: auto-suggestion triggers at any cursor position in the query input. See this issue.
FEATURE: vmui: update error messages on the Query page for enhanced clarity. See this pull request.
BUGFIX: downsampling: skip unnecessary index lookups if downsampling wasn't set for ENT versions of VictoriaMetrics. Before, users of VictoriaMetrics ENT could have experience elevated CPU usage even if no downsampling was configured. The issue was introduced in v1.100.0.
BUGFIX: downsampling: properly populate downsampling metadata for data parts created by VictoriaMetrics ENT versions lower than v1.100.0. The bug could trigger the downsampling actions for parts that were downsampled already. This bug doesn't have any negative effect apart from spending extra CPU resources on the repeated downsampling. The issue was introduced in v1.100.0.
BUGFIX: vmalert: supported any status codes from the range 200-299 from alertmanager. Previously, only 200 status code considered a successful action. See this issue.
BUGFIX: vmalert: avoid blocking /api/v1/rules, /api/v1/alerts, /metrics APIs when alerting rule uses template functions query, which could takes a while to execute. See this issue.
BUGFIX: vmalert: fix links with anchors in vmalert's UI. Starting from v1.99.0 vmalert could ignore anchors pointing to specific rule groups if search param was present in URL.
BUGFIX: vmauth: don't treat concurrency limit hit as an error of the backend. Previously, hitting the concurrency limit would increment both vmauth_concurrent_requests_limit_reached_total and vmauth_user_request_backend_errors_total counters. Now, only concurrency limit counter is incremented. Updates this issue.
