Public bug reported:
Ubuntu 22.04
Telegraf is configured with docker input:
[[inputs.docker]]
endpoint = "unix:///run/podman/podman.sock"
gather_services = false
source_tag = false
container_name_include = []
container_name_exclude = []
storage_objects = []
timeout = "5s"
docker_label_include = []
docker_label_exclude = []
if /run/podman/podman.sock is missing while (re)starting telegraf service, then
telegraf 1.36.3-1 and latest as of now, 1.36.4-1, will crash at startup:
[root@int2fvpvms001-scl-five9lab-com telegraf.d]# dpkg-query -W |grep telegraf
telegraf 1.36.4-1
[root@int2fvpvms001-scl-five9lab-com telegraf.d]# rm -f /run/podman/podman.sock
[root@int2fvpvms001-scl-five9lab-com telegraf.d]# systemctl restart telegraf
[root@int2fvpvms001-scl-five9lab-com telegraf.d]# systemctl status telegraf
