#1

Originally published at: https://www.influxdata.com/blog/release-announcement-telegraf-1-7-3-influxdb-1-6-1-and-kapacitor-1-5-1/

A new maintenance release for Telegraf is available now.

This maintenance release for Telegraf includes the following updates:
  1. Agent
    • The output buffer is now locked when adding new metrics to avoid concurrency issues.
    • The agent will preserve metric type when using filters in output plugins.
  2. Docker Input
    • The required docker API version has been reduced to 1.21.
  3. InfluxDB Output
    • Updated the error message to be more descriptive when the url cannot be parsed.
  4. Interrupts Input
    • We now skip bad entries for this input.
  5. yslog Input
    • Preserve leading whitespace commonly used for indentation when logging stack traces.
  6. ZFS Input
    • Fixed a parse error that happened on FreeBSD 11.2.
New maintenance releases for InfluxDB and Kapacitor are also available now.sp This maintenance release for InfluxDB includes the following updates:
  1. Performance Improvements
    • Allows for faster merging of large series sets. This improves query planning time by approximately 20%; however, a large amount of time is still spent building the bitsets.
    • Significantly improve the performance of influx_inspect buildtsi. This makes building a TSI index around 4-10 times faster than previous releases.
    • Improve the performance of the storage read service when querying a single measurement by providing a more efficient means to get the field keys for a measurement and using an iterator that only iterates over that single measurement, rather than iterating over all measurements.
  2. Configuration Options
    • Security — existing behavior is maintained by default; however, if you wish to restrict the security options by TLS version and a specific list of supported ciphers, the ability to do so is now made possible through configuration settings.
    • Compactions — by default the maximum number of processors used by the compaction service represents 50% of the total with no upper limit. This restores the behavior prior to the 1.5 release. You may set a fixed limit to a number smaller than 50% of the available processors.
The Kapacitor releases contain a small number of defect fixes. Refer to the release notes for specifics: The binaries for the latest open source release can be found on our downloads page.
