It’s not clear if you are installing on Debian or Red Hat or Docker… It’s not clear how far you are in the installation process or what commands you have run… It’s not clear if you have installed the other required parts such as mongo or Elasticsearch or OpenSearch. It is not clear where you have your screen shot of the installation page is from (We are not Graylog employees) It is not clear if you have installed the plugins portion of the install as @gsmith suggested… It is not clear if you applied for the free enterprise license and have a reply… All you have given us so far is a screen shot of running Graylog manually… which isn’t how it’s normally started, with a series of errors related to the installation being incomplete… but I don’t know where you are in the installation. You really do have to give more information about where you are and what you are doing for us to give you help on how to resolve issues… I know we have posted these for you before Tips for Asking Questions and How to ask questions please consider that we can help you better when you describe the issue and environment with relevant (and obfuscated if need be) detail…
