VictoriaMetrics v1.39.4 Release Notes

Release Date: 2020-08-09 // over 3 years ago

  • 🔄 Changes since v1.39.3

    • 🔋 FEATURE: improve query performance and concurrency on systems with big number of CPU cores (16+ vCPUs).
    • 🔋 FEATURE: limit the maximum memory usage and reduce CPU trashing on vmstorage when multiple heavy queries are executed. See #648 .
    • 🔋 FEATURE: improve PromQL compatibility at https://promlabs.com/promql-compliance-test-results-victoriametrics/ . See #673 , #674 , #675
    • FEATURE: vmagent: export scrape_samples_added per-target metric like Prometheus does. This metric may be useful for detecting targets with high churn rate for the exported metrics. See #683
    • 🔋 FEATURE: vmalert: extend exported metrics. See #573 .
    • 🔋 FEATURE: vmauth: properly trigger browser auth dialog. See #680
    • 🔋 FEATURE: slow down concurrent searches when the number of concurrent inserts reaches the limit. This should improve data ingestion performance when heavy searches are executed. See #648 and #618
    • FEATURE: export vm_nfs_pending_dirs_to_remove metric for monitoring the number of pending directories that couldn't be removed due to NFS lock
    • BUGFIX: rename vm_cache_size_entries{type="storage/prefetchedMetricIDs"} to vm_cache_entries{type="storage/prefetchedMetricIDs"} to be consistent with other vm_cache_entries metrics
    • BUGFIX: vmauth: add missing -tls* flags to *-cluster release. See #677
