on GitHub

Released at 2023-10-03

• FEATURE: add -elasticsearch.version command-line flag, which can be used for specifying Elasticsearch version returned by VictoriaLogs to Filebeat at elasticsearch bulk API. This helps resolving this issue.

• FEATURE: expose the following metrics at /metrics page:

  • vl_data_size_bytes{type="storage"} - on-disk size for data excluding log stream indexes.
  • vl_data_size_bytes{type="indexdb"} - on-disk size for log stream indexes.

• FEATURE: add -insert.maxFieldsPerLine command-line flag, which can be used for limiting the number of fields per line in logs sent to VictoriaLogs via ingestion protocols. This helps to avoid issues like this.

• FEATURE: expose vl_http_request_duration_seconds histogram at the /metrics page. Thanks to @crossoverJie for this pull request.

• FEATURE: add support of -storage.minFreeDiskSpaceBytes command-line flag to allow switching to read-only mode when running out of disk space at -storageDataPath. See this issue.

• BUGFIX: fix possible panic when no data is written to VictoriaLogs for a long time. See this issue. Thanks to @crossoverJie for filing and fixing the issue.

• BUGFIX: add /insert/loky/ready endpoint, which is used by Promtail for healthchecks. This should remove unsupported path requested: /insert/loki/ready warning logs. See this comment.

• BUGFIX: prevent from panic during background merge when the number of columns in the resulting block exceeds the maximum allowed number of columns per block. See this issue.
