VictoriaLogs changelog

The following tip changes can be tested by building VictoriaLogs from the latest commit of VictoriaMetrics repository according to these docs

tip

v0.5.0

Released at 2024-03-01

• FEATURE: support the ability to limit the number of returned log entries from HTTP querying API by passing limit query arg. Previously all the matching log entries were returned until closing the response stream. See this feature request. Thanks to @dmitryk-dk for the pull request.

• BUGFIX: do not panic on incorrect regular expression in stream filter. Thanks to @XLONG96 for the bugfix.

• BUGFIX: properly determine when the assisted merge is needed. Previously the logs for determining whether the assisted merge is needed was broken. This could lead to too big number of parts under high data ingestion rate. Thanks to @lujiajing1126 for the fix.

• BUGFIX: properly stop execution of aborted query when the query doesn't contain _stream filter. Previously such a query could continue consuming resources after being aborted by the client. Thanks to @z-anshun for the fix.

v0.4.2

Released at 2023-11-15

• BUGFIX: properly locate logs for the requested streams. Previously logs for some streams may be missing in query results. See this issue. Thanks to @XLONG96 for the fix!
• BUGFIX: web UI: properly sort found logs by time. See this issue.

v0.4.1

Released at 2023-10-04

• BUGFIX: fix the free space verification process in VictoriaLogs that was erroneously shifting to read-only mode, despite there being sufficient free space available. See this issue.

v0.4.0

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.

v0.3.0

Released at 2023-07-20

• FEATURE: add support for data ingestion via Promtail (aka default log shipper for Grafana Loki). See these and these docs.

v0.2.0

Released at 2023-07-17

• FEATURE: support short form of _time filters over the last X minutes/hours/days/etc. For example, _time:5m is a short form for _time:(now-5m, now], which matches logs with timestamps for the last 5 minutes. See these docs for details.
• FEATURE: add ability to specify offset for the selected time range. For example, _time:5m offset 1h is equivalent to _time:(now-5m-1h, now-1h]. See these docs for details.
• FEATURE: LogsQL: replace exact_prefix("...") with exact("..."*). This makes it consistent with i() filter, which can accept phrases and prefixes, e.g. i("phrase") and i("phrase"*). See these docs.
