7. DataDog integrations
● Accept data from new versions of DataDog agent via DataDog v2 API

8. DataDog integrations
● Accept data from new versions of DataDog agent via DataDog v2 API
● Accept data from DataDog AWS lambda extensions

9. OpenTelemetry data ingestion via Amazon Firehose
● Accept OTEL metrics from Amazon Firehose

10. OpenTelemetry: Prometheus-compatible naming
● -opentelemetry.usePrometheusNaming command-line flag
● Converts metric names and labels into Prometheus-compatible naming in the
same way as OTEL collector does

11. Hetzner service discovery
● Discover scrape targets at Hetzner Cloud and Hetzner Robot
● hetzner_sd_configs

12. Per-tenant and per-label downsampling (enterprise feature)
● Individual downsampling configs per distinct sets of tenants
○ -downsampling.period=’{vm_account_id=~”1|5|10”}:1d:5m’
-downsampling.period=’{vm_account_id=~”42”}:1d:1h’
-downsampling.period=’1d:1m’

13. Per-tenant and per-label downsampling (enterprise feature)
● Individual downsampling configs per distinct sets of tenants
○ -downsampling.period=’{vm_account_id=~”1|5|10”}:1d:5m’
-downsampling.period=’{vm_account_id=~”42”}:1d:1h’
-downsampling.period=’1d:1m’
● Individual downsampling configs per distinct sets of time series
○ -donwnsampling.period=’{env!=”prod”}:1d:1h’
-donwsampling.period=’1d:5m’

14. New Graphite query functions
● aggregateSeriesLists
● diffSeriesLists
● multiplySeriesLists
● sumSeriesLists

15. mTLS support
● Every VictoriaMetrics Enterprise component verifies client TLS certificates if
-mtls command-line flag is set

16. mTLS support
● Every VictoriaMetrics Enterprise component verifies client TLS certificates if
-mtls command-line flag is set
● Vmauth Enterprise supports mTLS-based request routing

17. vmauth: improved request routing
● Host-based request routing
○ http://some-host/foo/bar -> http://some-backend/foo/bar

18. vmauth: improved request routing
● Host-based request routing
○ http://some-host/foo/bar -> http://some-backend/foo/bar
● Query args-based request routing
○ http://some-host/foo/bar?db=foo -> http://some-backend/foo/bar

19. vmauth: improved request routing
● Host-based request routing
○ http://some-host/foo/bar -> http://some-backend/foo/bar
● Query args-based request routing
○ http://some-host/foo/bar?db=foo -> http://some-backend/foo/bar
● Arbitrary header value-based request routing
○ http://some-host/foo/bar with ‘TenantID: 123` header -> http://some-backend/foo/bar

20. vmauth: DNS-based load balancing
● Even load balancing across IP addresses behind a single hostname
● Works great with vminsert and vmselect services

21. MetricsQL: new functions
● sum_eq_over_time
● sum_gt_over_time
● sum_le_over_time
● count_values_over_time - counts the number of unique sample values over time

22. MetricsQL: improved label filters’ propagation
● label_set(q1, "a", "b") + q2{c="d"} is automatically transformed to
label_set(q1{c="d"}, "a", "b") + q2{a="b",c="d"}
● Label filters are propagated across any label manipulation functions
● This improves performance for such queries by eliminating the need to fetch
unused time series
