As i saw connection was established in input menu but no log was received.
Then i checked about 1 hour later and saw that log was received. Timestamp was exactly the same when i sent log but as mentioned before it appeared about 1 hour later.
what possible issue can be?
Graylog version - 5.1.11
Opensearch version - 2.12.0
OS - Debian 11
To clarify, you are saying that when you post a GELF message to your graylog server, the message is not viewable in graylog for about an hour, after which you can see the message. The timestamp of the message is also correct. Is that accurate?
Can you share a screenshot and copy of the message from graylog? Can you also verify that your is configured appropruately in graylog in your user profile
