VictoriaMetrics/VictoriaMetrics v1.87.6 on GitHub

Released at 2023-05-18

v1.87.x is a line of LTS releases (e.g. long-time support). It contains important up-to-date bugfixes.
The v1.87.x line will be supported for at least 12 months since v1.87.0 release

SECURITY: upgrade Go builder from Go1.20.3 to Go1.20.4. See the list of issues addressed in Go1.20.4.
SECURITY: upgrade base docker image (alpine) from 3.17.3 to 3.18.0. See alpine 3.18.0 release notes.
SECURITY: serve /robots.txt content to disallow indexing of the exposed instances by search engines. See this issue for details.
BUGFIX: reduce the probability of sudden increase in the number of small parts on systems with small number of CPU cores.
BUGFIX: reduce the possibility of increased CPU usage when data with timestamps older than one hour is ingested into VictoriaMetrics. This reduces spikes for the graph sum(rate(vm_slow_per_day_index_inserts_total)). See this pull request.
BUGFIX: do not ignore trailing empty field in CSV lines when importing data in CSV format. See this issue.
BUGFIX: disallow " chars when parsing Prometheus label names, since they aren't allowed by Prometheus text exposition format. Previously this could result in silent incorrect parsing of incorrect Prometheus labels such as foo{"bar"="baz"} or {foo:"bar",baz="aaa"}. See this issue.
BUGFIX: MetricsQL: fix a panic when the duration in the query contains uppercase M suffix. Such a suffix isn't allowed to use in durations, since it clashes with a million suffix, e.g. it isn't clear whether rate(metric[5M]) means rate over 5 minutes, 5 months or 5 million seconds. See this and this issues.
BUGFIX: VictoriaMetrics cluster: prevent from possible panic when the number of vmstorage nodes increases when automatic vmstorage discovery is enabled.
BUGFIX: properly limit the number of OpenTSDB HTTP concurrent requests specified via -maxConcurrentInserts command-line flag. See this issue. Thanks to @zouxiang1993 for the fix.
BUGFIX: vmalert: properly return empty slices instead of nil for /api/v1/rules and /api/v1/alerts API handlers. See this issue.
BUGFIX: vmagent: add __meta_kubernetes_endpoints_name label for all ports discovered from endpoint. Previously, ports not matched by Service did not have this label. See this issue for details. Thanks to @thunderbird86 for discovering and fixing the issue.
BUGFIX: fix possible infinite loop during indexdb rotation when -retentionTimezoneOffset command-line flag is set and the local timezone is not UTC. See this issue. Thanks to @faceair for the fix.
BUGFIX: vmauth: do not return invalid auth credentials in http response by default, since it may be logged by client. See this issue.
BUGFIX: alerts-health: update threshold for TooHighMemoryUsage alert from 90% to 80%, since 90% is too high for production environments.
BUGFIX: vmagent: properly handle the vm_promscrape_config_last_reload_successful metric after config reload. See this issue.
BUGFIX: stream aggregation: fix bug with duplicated labels during stream aggregation via single-node VictoriaMetrics. See this issue.
BUGFIX: stream aggregation: suppress series after dedup error message in logs when -remoteWrite.streamAggr.dedupInterval command-line flag is set at vmagent or when -streamAggr.dedupInterval command-line flag is set at single-node VictoriaMetrics.
