This new maintenance release for Telegraf is available now.

Common

  • Cookie common plugin now uses reader over readcloser and regenerates cookie-jar during reauthentication.

Input plugin updates

  • OpenStack Input
    • The OpenStack plugin now uses the v3 volume library to fix an issue with storage volume API fails.
  • MQTT Consumer Input
    • We fixed an issue with topic parsing that would produce an error if the topic had a prefix of /.
  • SNMP Trap Input
    • We resolved a nil map panic that occurred when running the plugin with the netSNMP translator.
  • SQL Server Input
    • We set a lower deadlock priority on queries in the plugin.

Parser plugin updates

  • Prometheus
    • The Histogram infinity bucket is now always present in the Prometheus parser.

Dependencies

  • Updated github.com/antchfx/jsonquery from 1.1.5 to 1.2.0
