Hi,
there is no index called just tenable, but tenable-2024.04 so I put it on my curl request
[root@siem_els ~]# curl -XGET '127.0.0.1:9200/tenable-2024.04/_search?q=' -u logserver
Enter host password for user 'logserver':
{"took":6,"timed_out":false,"_shards":{"total":2,"successful":2,"skipped":0,"failed":0},"hits":{"total":{"value":0,"relation":"eq"},"max_score":null,"hits":[]}}
Here what I see in discover
