InfluxData releases Telegraf 1.21.3, updating SNMP, HTTP, and OPC-UA input plugins, along with fixes for the JSON parser

Navigate to:

The new maintenance release for Telegraf is available now.

Input plugin updates

  • Execd Input
    • We resolved a text format parsing error for Prometheus parsing due to an unexpected end of input stream by adding a newline in the Execd plugin.
  • IPset Input
    • Plugin now does an init check for the ipset command before running. This now prevents a panic from occurring after startup.
  • OPC-UA Input
    • We fixed an issue where fields were being duplicated.
  • HTTP Input
    • The plugin now sends an actual empty http body when no body is set. This prevents a server side error message.
  • SNMP Input
    • We fixed an issue where the SNMP plugin would error when a MIBs folder didn't exist.
  • SNMP Trap Input
    • We fixed the translation of partially resolved OIDs.

Output plugin updates

  • AMQP Output
    • Plugin now closes the last connection when writing errors to avoid connection leaks.
  • Timestream Output
    • We fixed an issue with batching logic with write records and introduced concurrent requests to the Timestream output plugin.
  • Stackdriver Output
    • Plugin now sends the correct interval start times for all counter metrics (keyed by name, tags and field).
  • Syslog Output
    • We correctly set the ASCII trailer per RFC 6587 for the Syslog output.

Parser plugin updates

  • Nagios Parser
    • Parser now logs correct errors when executing commands. Real error messages will be written to the logs for problems to be properly debugged.
  • JSON v2 Parser
    • We fixed the timestamp precision when using unix_ns timestamp format.
  • Wavefront Parser
    • We added the missing setting wavefront_disable_prefix_conversion.
