Help with Cluster

Elastic Stack Elasticsearch
3

Thanks for the information. I don't mind it being there, I would just
confused of why it was there. If it stays there, will my cluster status
continue to show red on the health? That was my main concern. Also, if it
stays there, I wish I could rename it from the default Lupo it is to the
name of the server so I can distinguish it better.

I'd not worry of the non data node.
It's only a node which connect to the cluster to give a client to logstash.

If you really don't want it, then you can use
Elasticsearch output plugin | Logstash Reference [8.11] | Elastic

I am working on building out a small POC for Logstash and Elasticsearch.
To start, I have a 2 server setup.

  • Server 1 - logstash1 - running "java -jar logstash-1.2.2-flatjar.jar
    agent -f indexer.conf"
    • This server is tailing logs from a syslog config file and then
      sending them to an Elasticsearch server.
- Server 2 - elasticsearch1 - running elasticsearch as a daemon

(CentOS box that i used an rpm instal - version - 0.90.3.)

  - This server is also running Kibana."java -jar 
  /etc/logstash/logstash-1.2.2-flatjar.jar web"

Overall things seem to be working pretty well. I started to do some
general diagnostics on the elasticsearch server to see how the cluster was
doing, and I saw that it was red.

[root@elasticsearch1 elasticsearch]# curl -XGET '

http://localhost:9200/_cluster/health?pretty=true'
{
"cluster_name" : "my-cluster",
"status" : "red",
"timed_out" : false,
"number_of_nodes" : 2,
"number_of_data_nodes" : 1,
"active_primary_shards" : 35,
"active_shards" : 35,
"relocating_shards" : 0,
"initializing_shards" : 0,
"unassigned_shards" : 55

When I saw that it was red and that there were 2 nodes, I was confused as
there should only be 1 elasticsearch node. Upon digging further, I see this:

[root@elasticsearch1 elasticsearch]# curl

localhost:9200/_nodes/process?pretty
{
"ok" : true,
"cluster_name" : "my-cluster",
"nodes" : {
"ab8COl6pTj-kJSzrXZTE2w" : {
"name" : "Lupo",
"transport_address" : "inet[/192.168.0.10:9300]",
"hostname" : "logstash1",
"version" : "0.90.3",
"attributes" : {
"client" : "true",
"data" : "false"
},
"process" : {
"refresh_interval" : 1000,
"id" : 4380,
"max_file_descriptors" : 3200
}
},
"FMgeliZPRdQZwy-IZ9MUIp" : {
"name" : "Elasticsearch Server1",
"transport_address" : "inet[/192.168.0.20:9300]",
"hostname" : "elasticsearch1",
"version" : "0.90.3",
"http_address" : "inet[/192.168.0.20:9200]",
"attributes" : {
"master" : "true"
},
"process" : {
"refresh_interval" : 1000,
"id" : 15653,
"max_file_descriptors" : 65535
}
}
}

I am confused why server1, logstash1, is showing up in the elasticsearch
cluster. I'm only running logstash as an indexer and not the built in
elasticsearch feature. How do I get this server to stop showing up in my
cluster? When I look on the logstash1 server, I don't see any elasticsearch
data or indexes like I do on my elasticsearch1 servers. So I don't think
data is truly going to it, but I don't want it to show up.

Thanks,
Eric
