Hi Arief, you should have a look into your elaticsearch logfiles like Jochen wrote. ES will tell you about what's going on in case something is happening.
Then, there are the various api's you could use to find out, why your cluster is yellow. Probably the different localhost:9200/_cat/ endpoints like nodes, indices and shards should help you to find the one that isn't settled and will help you to find out why. https://www.elastic.co/guide/en/elasticsearch/reference/1.4/cat.html You can further install plugins into your ES nodes like kopf, the german translation of head, which is another plugin that would give you visual overview into your cluster. https://github.com/lmenezes/elasticsearch-kopf Have a look into these, Marcus -- You received this message because you are subscribed to the Google Groups "Graylog Users" group.
