Changes

  • FEATURE: optimize query performance by up to 10x on systems with many CPU cores. See this tweet.

  • FEATURE: add the following metrics at /metrics page for every VictoraMetrics app:

    • process_resident_memory_anon_bytes - RSS share for memory allocated by the process itself. This share cannot be freed by the OS, so it must be taken into account by OOM killer.
    • process_resident_memory_file_bytes - RSS share for page cache memory (aka memory-mapped files). This share can be freed by the OS at any time, so it must be ignored by OOM killer.
    • process_resident_memory_shared_bytes - RSS share for memory shared with other processes (aka shared memory). This share can be freed by the OS at any time, so it must be ignored by OOM killer.
    • process_resident_memory_peak_bytes - peak RSS usage for the process.
    • process_virtual_memory_peak_bytes - peak virtual memory usage for the process.

  • FEATURE: accept and enforce extra_label=<label_name>=<label_value> query arg at Graphite APIs.

  • FEATURE: use Influx field as metric name if measurement is empty and -influxSkipSingleField command-line is set. See this issue.

  • FEATURE: vmagent: add -promscrape.consul.waitTime command-line flag for tuning the maximum wait time for Consul service discovery. See this issue.

  • FEATURE: vmagent: add vm_promscrape_discovery_kubernetes_stale_resource_versions_total metric for monitoring the frequency of too old resource version errors during Kubernetes service discovery.

  • FEATURE: single-node VictoriaMetrics: log metrics with timestamps older than -search.cacheTimestampOffset compared to the current time. See these docs for details.

  • BUGFIX: prevent from infinite loop on {__graphite__="..."} filters when a metric name contains *, { or [ chars.

  • BUGFIX: prevent from infinite loop in /metrics/find and /metrics/expand Graphite Metrics API handlers when they match metric names or labels with *, { or [ chars.

  • BUGFIX: do not merge duplicate time series during requests to /api/v1/query. See #1141

  • BUGFIX: vmagent: properly handle too old resource version error messages from Kubernetes watch API. See #1150

  • BUGFIX: vmagent: do not retry sending data blocks if remote storage returns 400 Bad Request error. The number of dropped blocks due to such errors can be monitored with vmagent_remotewrite_packets_dropped_total metrics. See #1149

  • BUGFIX: properly calculate summarize and *Series functions in Graphite Render API.
