# Tenzir Node v4.18.0 ## 馃殌 Features ### Emit connection status metrics from the platform Jul 10, 2024 路 [@dominiklohmann](https://github.com/dominiklohmann) 路 [#4374](https://github.com/tenzir/tenzir/pull/4374) The `tenzir.metrics.platform` metrics records every second whether the connection to the Tenzir Platform is working as expected from the node鈥檚 perspective. ### Introduce API metrics Jul 10, 2024 路 [@dominiklohmann](https://github.com/dominiklohmann) 路 [#4368](https://github.com/tenzir/tenzir/pull/4368) The new `tenzir.metrics.api` metrics record every API call made to a Tenzir Node. ### Add an optional `name` argument to the `metrics` operator Jul 9, 2024 路 [@dominiklohmann](https://github.com/dominiklohmann) 路 [#4369](https://github.com/tenzir/tenzir/pull/4369) The `metrics` operator now optionally takes a metric name as an argument. For example, `metrics cpu` only shows CPU metrics. This is functionally equivalent to `metrics | where #schema == "tenzir.metrics.cpu"`. ### PRs 4339-4365 Jul 5, 2024 路 [@Dakostu](https://github.com/Dakostu) 路 [#4339](https://github.com/tenzir/tenzir/pull/4339) The `publish`, `subscribe`, `import`, `export`, `lookup` and `enrich` operators deliver their own, operator-specific metrics now. ## 馃敡 Changes ### Revamp the `export` operator Jul 10, 2024 路 [@dominiklohmann](https://github.com/dominiklohmann) 路 [#4365](https://github.com/tenzir/tenzir/pull/4365) The previously deprecated `--low-priority` option for the `export` operator no longer exists. The new `--parallel ` option allows tuning how many worker threads the operator uses at most for querying persisted events. ### Raise the default and max timeouts for `/serve` Jul 10, 2024 路 [@dominiklohmann](https://github.com/dominiklohmann) 路 [#4370](https://github.com/tenzir/tenzir/pull/4370) We raised the default and maximum long-polling timeouts for `/serve` from 2s and 5s to 5s and 10s, respectively. ### Simplify the node actor setup Jul 5, 2024 路 [@dominiklohmann](https://github.com/dominiklohmann) 路 [#4343](https://github.com/tenzir/tenzir/pull/4343) The deprecated `vast` symlink for the `tenzir-ctl` binary that offeres backwards compatiblity with versions older than Tenzir v4鈥攚hen it was called VAST鈥攏o longer exists. The deprecated `tenzir.db-directory` option no longer exists. Use `tenzir.state-directory` instead. ### Prepare the pipeline manager for TQLv2 Jul 4, 2024 路 [@jachris](https://github.com/jachris) 路 [#4348](https://github.com/tenzir/tenzir/pull/4348) Diagnostics from managed pipelines are now deduplicated, showing each diagnostic at most once for each run. ### Push expressions into `subscribe` for better metrics Jul 4, 2024 路 [@dominiklohmann](https://github.com/dominiklohmann) 路 [#4349](https://github.com/tenzir/tenzir/pull/4349) Pipeline activity for pipelines starting with `subscribe | where ` will no longer report ingress that does not match the provided filter expression. ## 馃悶 Bug Fixes ### Add missing time format specifiers for the static binary Jul 10, 2024 路 [@tobim](https://github.com/tobim) 路 [#4366](https://github.com/tenzir/tenzir/pull/4366) The time parser now accepts the `%F`, `%g`, `%G`, `%u`, `%V`, `%z`, and `%Z` format specifiers. ### Allow immediate restarts of the TCP listen connector Jul 9, 2024 路 [@tobim](https://github.com/tobim) 路 [#4367](https://github.com/tenzir/tenzir/pull/4367) The `tcp` connector no longer fails in listen mode when you try to restart it directly after stopping it. ### Honor proxy settings in the SQS connector Jul 9, 2024 路 [@tobim](https://github.com/tobim) 路 [#4359](https://github.com/tenzir/tenzir/pull/4359) The SQS connector now honors system proxy settings. ### Fix open partition tracking in the `lookup` operator Jul 9, 2024 路 [@dominiklohmann](https://github.com/dominiklohmann) 路 [#4363](https://github.com/tenzir/tenzir/pull/4363) We fixed a rare bug that caused the `lookup` operator to exit unexpectedly when using a high value for the operator鈥檚 `--parallel` option. ### Push expressions into `subscribe` for better metrics Jul 4, 2024 路 [@dominiklohmann](https://github.com/dominiklohmann) 路 [#4349](https://github.com/tenzir/tenzir/pull/4349) Pipelines of the form `export --live | where ` failed to filter with type extractors or concepts. This now works as expected. ### Fix possible crash when one of multiple subscribers disconnects Jul 3, 2024 路 [@dominiklohmann](https://github.com/dominiklohmann) 路 [#4346](https://github.com/tenzir/tenzir/pull/4346) We fixed a rare crash when one of multiple `subscribe` operators for the same topic disconnected while at least one of the other subscribers was overwhelmed and asked for corresponding publishers to throttle. ### Remove the zero-size check in the split\_at\_null() input loop Jul 2, 2024 路 [@Dakostu](https://github.com/Dakostu) 路 [#4341](https://github.com/tenzir/tenzir/pull/4341) We fixed a rarely occurring issue in the `gelf` parser that led to parsing errors for some events.
