Error : Could not connect to ElasticSearch

shayz · April 9, 2018, 8:43am

Thanx @jochen will do. Last question, are there any compatibility issues in this case with version numbers?
Debian 8, Graylog 2.4, Elasticsearch 6.2.3, MongoDB 3.6

jochen · April 9, 2018, 8:58am

Graylog 2.x doesn’t work with Elasticsearch 6.x.

http://docs.graylog.org/en/2.4/pages/installation.html#system-requirements

Just give it up until they come up with some more friendly backend than ElasticSearch. It gets screwed up randomly and you won’t be able to resolve unless you are an ElasticSearch expert and linux guru as well.

jochen · April 9, 2018, 1:55pm

It works pretty well for a few people.

Please continue this discussion in the topic you’ve created: Graylog more friendly to run and manage please

shayz · April 9, 2018, 1:58pm

@jochen Yes, my bad. Just reinstalled everything. Could not spend more time for troubleshooting. So now this is the versions:
Graylog version: 2.4.3
Elasticsearch version: 5.6.8
MongoDB version: 3.6.3

What can i do that it does not happen again with the Elasticsearch? At the moment I have no inputs just a fresh install and everything is working (looks so!). All three components are on the same VM. Except the cluster.name = graylog I have not changed any default setting in ES configs. I don’t understand when I need to add the network.host is also as comment. My underestanding is that it should not be changed until I have more nodes to connect, so now which all are on the same machine I should not change it. Is that correct?

shayz · April 12, 2018, 10:27am

@jochen seems that changing the heap size for ES has solved the problem but there comes another problem that in web interface system/nodes (I have one node) the node is periodically removing and showing.

Then it shows up and then again hides!

jochen · April 12, 2018, 1:05pm

What are the JVM settings of Graylog and Elasticsearch on that machine?
What’s in the logs of that Graylog node?

shayz · April 13, 2018, 10:11am

@jochen In graylog Java options I have these:

    JAVA=/usr/bin/java

# Default Java options for heap and garbage collection.
GRAYLOG_SERVER_JAVA_OPTS="-Xms1g -Xmx1g -XX:NewRatio=1 -server -XX:+ResizeTLAB -XX:+UseConcMarkSweepGC -XX:+CMSConcurrentMTEnabled -XX:+CMSClassUnloadingEnabled -XX:+UseParNewGC -XX:-OmitStackTraceInFastThrow"

# Pass some extra args to graylog-server. (i.e. "-d" to enable debug mode)
GRAYLOG_SERVER_ARGS=""

# Program that will be used to wrap the graylog-server command. Useful to
# support programs like authbind.
GRAYLOG_COMMAND_WRAPPER=""

and for ES just this one is not commented: (Default setting)

ES_STARTUP_SLEEP_TIME=5

In Graylog logs I have many warnings like these: (I have no pipeline in Graylog at the moment )

Please post the complete logs of your Graylog node and check that there are no incompatible plugins in the plugins directory of Graylog.

@jochen Sorry my bad, the last error was from yesterday and since then I don’t have any logs, I hope it means that its been fixed
+The disappearing issue for the node is not happening anymore so lets assume it as fixed.
Really thanks for all your help
