Hello , I got the email list from irc.freenode #hawkular We are attempting to make the events data (from agents) persistent, we expect the external elastic search allows to have some sort of persistance if there is a failure of the APM itself. We checked the embedded elastic, and if the APM (wilfly) goes down, the data from previous events does not remain. So, we expected that an external elastic could suffice this , we used this rpm wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.6.3.rpm and on the same host we set up the APM 0.14 distrbution we pointed the standalone.conf with the following configuration: export HAWKULAR_APM_ELASTICSEARCH_CLUSTER="elasticsearch" export HAWKULAR_APM_ELASTICSEARCH_HOSTS="localhost:9200" unfortunately, this throws an error starting the APM *15:54:37,520 SEVERE [org.hawkular.apm.server.elasticsearch.ElasticsearchBootstrap] (ServerService Thread Pool -- 91) Failed to initialise Elasticsearch: org.elasticsearch.client.transport.NoNodeAvailableException: None of the configured nodes are available: []* *16:25:16,525 INFO [org.elasticsearch.client.transport] (elasticsearch[Jaren][generic][T#2]) [Jaren] failed to get node info for [#transport#-1][cllnxHawkular][inet[localhost/127.0.0.1:9300]], disconnecting...: org.elasticsearch.transport.NodeDisconnectedException: [][inet[localhost/127.0.0.1:9300]][cluster:monitor/nodes/info] disconnected* is there a configuration for the elastic search ? does the external elasticsearch able to make the data persistent ?
