I donno the answer but I had done the translation on google translate to read through the question, so in case someone else needed the translated question (If anything is improper, pardon me for the copy paste) here it is:
First of all, I would like you to make it from the current explanation.
Currently, Splunk Enterprise is operated on AWS.
I'd like to connect to a MySQL server on the same instance using Splunk DB connect and acquire data, but "Connection error" will be displayed and it will not work.
Previously, it was successful to connect to the MySQL server in the PC from the Splunk DB connect of your local PC and obtain the data.
And, I think that there is no mistake in the destination port, host port, etc.
· Based on the above conditions, what is considered to be any possible cause of the error?
· Or do you have to mediate splunk forwarder to connect My SQL with Splunk Enterprise in the same instance on AWS?
Someone, thank you for your answer.
