- Switch from summary to histogram for vl_http_request_duration_seconds metric. This allows calculating request duration quantiles across multiple hosts via histogram_quantile(0.99, sum(vl_http_request_duration_seconds_bucket) by (vmrange)). - Take into account only successfully processed data ingestion requests when updating vl_http_request_duration_seconds histogram. Failed requests are ignored, since they may significantly skew measurements. - Clarify the description of the change at docs/VictoriaLogs/CHANGELOG.md.

# VictoriaLogs changelog
|
|
|
|
The following `tip` changes can be tested by building VictoriaLogs from the latest commit of [VictoriaMetrics](https://github.com/VictoriaMetrics/VictoriaMetrics/) repository
|
|
according to [these docs](https://docs.victoriametrics.com/VictoriaLogs/QuickStart.html#building-from-source-code)
|
|
|
|
## tip
|
|
|
|
* FEATURE: add `-elasticsearch.version` command-line flag, which can be used for specifying Elasticsearch version returned by VictoriaLogs to Filebeat at [elasticsearch bulk API](https://docs.victoriametrics.com/VictoriaLogs/data-ingestion/#elasticsearch-bulk-api). This helps resolving [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4777).
|
|
* FEATURE: expose the following metrics at [/metrics](monitoring) page:
|
|
* `vl_data_size_bytes{type="storage"}` - on-disk size for data excluding [log stream](https://docs.victoriametrics.com/VictoriaLogs/keyConcepts.html#stream-fields) indexes.
|
|
* `vl_data_size_bytes{type="indexdb"}` - on-disk size for [log stream](https://docs.victoriametrics.com/VictoriaLogs/keyConcepts.html#stream-fields) 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](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4762).
|
|
* FEATURE: expose `vl_http_request_duration_seconds` histogram at the [/metrics](https://docs.victoriametrics.com/VictoriaLogs/#monitoring) page. Thanks to @crossoverJie for [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/4934).
|
|
|
|
* BUGFIX: fix possible panic when no data is written to VictoriaLogs for a long time. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4895). 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](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4762#issuecomment-1690966722).

|
|
|
## [v0.3.0](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v0.3.0-victorialogs)
|
|
|
|
Released at 2023-07-20
|
|
|
|
* FEATURE: add support for data ingestion via Promtail (aka default log shipper for Grafana Loki). See [these](https://docs.victoriametrics.com/VictoriaLogs/data-ingestion/Promtail.html) and [these](https://docs.victoriametrics.com/VictoriaLogs/data-ingestion/#loki-json-api) docs.
|
|
|
|
## [v0.2.0](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/v0.2.0-victorialogs)
|
|
|
|
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](https://docs.victoriametrics.com/VictoriaLogs/keyConcepts.html#time-field) for the last 5 minutes. See [these docs](https://docs.victoriametrics.com/VictoriaLogs/LogsQL.html#time-filter) 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](https://docs.victoriametrics.com/VictoriaLogs/LogsQL.html#time-filter) for details.
|
|
* FEATURE: [LogsQL](https://docs.victoriametrics.com/VictoriaLogs/LogsQL.html): replace `exact_prefix("...")` with `exact("..."*)`. This makes it consistent with [i()](https://docs.victoriametrics.com/VictoriaLogs/LogsQL.html#case-insensitive-filter) filter, which can accept phrases and prefixes, e.g. `i("phrase")` and `i("phrase"*)`. See [these docs](https://docs.victoriametrics.com/VictoriaLogs/LogsQL.html#exact-prefix-filter).
