[ajeetraina]

@karanveersingh5623 I noticed that fluentd is listed in CNCF but there it is not listed.

[abhimazu]

@ajeetraina Check the cncf json that is created, if there is a name mismatch, it will show unlisted. As I am pulling from CNCF directly, I cannot edit the names in between, as they would be considered synthetic then.
