Two days ago, I noticed that my Elasticsearch cluster was unavailable. I've followed the suggestions provided in the setup documentation but I still cannot get the cluster to turn green.
Graylog could not successfully connect to the Elasticsearch cluster. If you're using multicast, check that it is working in your network and that Elasticsearch is accessible. Also check that the cluster name setting is correct. Read how to fix this in the Elasticsearch setup documentation. <http://docs.graylog.org/en/1.3/pages/configuring_es.html#configuration> No changes were made between the time it was working and when it stopped working. Any help would be greatly appreciated. Thank you *Graylog Config* # If you are running more than one instances of graylog-server you have to select one of these # instances as master. The master will perform some periodical tasks that non-masters won't perform. is_master = true # The auto-generated node ID will be stored in this file and read after restarts.

Application developers should # consult the guide at <http://elasticsearch.org/guide>. # # The installation procedure is covered at # <http://elasticsearch.org/guide/en/elasticsearch/reference/current/setup.html>. # # Elasticsearch comes with reasonable defaults for most settings, # so you can try it out without bothering with configuration. # # Most of the time, these defaults are just fine for running a production # cluster. If you're fine-tuning your cluster, or wondering about the # effect of certain configuration option, please _do ask_ on the # mailing list or IRC channel [http://elasticsearch.org/community]. # Any element in the configuration can be replaced with environment variables # by placing them in ${...} notation. For example: # #node.rack: ${RACK_ENV_VAR} # For information on supported formats and syntax for the config file, see # <http://elasticsearch.org/guide/en/elasticsearch/reference/current/setup-configuration.html> ################################### Cluster ################################### # Cluster name identifies your cluster for auto-discovery. If you're running # multiple clusters on the same network, make sure you're using unique names. # #cluster.name: elasticsearch #################################### Node ##################################### # Node names are generated dynamically on startup, so you're relieved # from configuring them manually. You can tie this node to a specific name: # #node.name: "Franz Kafka" # Every node can be configured to allow or deny being eligible as the master, # and to allow or deny to store the data. # # Allow this node to be eligible as a master node (enabled by default): # #node.master: true # # Allow this node to store data (enabled by default): # #node.data: true # You can exploit these settings to design advanced cluster topologies. # # 1. You want this node to never become a master node, only to hold data. # This will be the "workhorse" of your cluster. # #node.master: false #node.data: true # # 2. You want this node to only serve as a master: to not store any data and # to have free resources. This will be the "coordinator" of your cluster. # #node.master: true #node.data: false # # 3. You want this node to be neither master nor data node, but # to act as a "search load balancer" (fetching data from nodes, # aggregating results, etc.) # #node.master: false #node.data: false # Use the Cluster Health API [http://localhost:9200/_cluster/health], the # Node Info API [http://localhost:9200/_nodes] or GUI tools # such as <http://www.elasticsearch.org/overview/marvel/>, # <http://github.com/karmi/elasticsearch-paramedic>, # <http://github.com/lukas-vlcek/bigdesk> and # <http://mobz.github.com/elasticsearch-head> to inspect the cluster state. # A node can have generic attributes associated with it, which can later be used # for customized shard allocation filtering, or allocation awareness. An attribute # is a simple key value pair, similar to node.key: value, here is an example: # #node.rack: rack314 # By default, multiple nodes are allowed to start from the same installation location # to disable it, set the following: #node.max_local_storage_nodes: 1 #################################### Index #################################### # You can set a number of options (such as shard/replica options, mapping # or analyzer definitions, translog settings, ...) for indices globally, # in this file. # # Note, that it makes more sense to configure index settings specifically for # a certain index, either when creating it or by using the index templates API. # # See <http://elasticsearch.org/guide/en/elasticsearch/reference/current/index-modules.html> and # <http://elasticsearch.org/guide/en/elasticsearch/reference/current/indices-create-index.html> # for more information. # Set the number of shards (splits) of an index (5 by default): # #index.number_of_shards: 5 # Set the number of replicas (additional copies) of an index (1 by default): # #index.number_of_replicas: 1 # Note, that for development on a local machine, with small indices, it usually # makes sense to "disable" the distributed features: # #index.number_of_shards: 1 #index.number_of_replicas: 0 # These settings directly affect the performance of index and search operations # in your cluster. Assuming you have enough machines to hold shards and # replicas, the rule of thumb is: # # 1. Having more *shards* enhances the _indexing_ performance and allows to # _distribute_ a big index across machines. # 2. Having more *replicas* enhances the _search_ performance and improves the # cluster _availability_. # # The "number_of_shards" is a one-time setting for an index. # # The "number_of_replicas" can be increased or decreased anytime, # by using the Index Update Settings API. # # Elasticsearch takes care about load balancing, relocating, gathering the # results from nodes, etc. Experiment with different settings to fine-tune # your setup. # Use the Index Status API (<http://localhost:9200/A/_status>) to inspect # the index status. #################################### Paths #################################### # Path to directory containing configuration (this file and logging.yml): # #path.conf: /path/to/conf # Path to directory where to store index data allocated for this node. # #path.data: /path/to/data # # Can optionally include more than one location, causing data to be striped across # the locations (a la RAID 0) on a file level, favouring locations with most free # space on creation.

(the range means that if the port is busy, it will automatically # try the next port). # Set the bind address specifically (IPv4 or IPv6): # #network.bind_host: 192.168.0.1 # Set the address other nodes will use to communicate with this node. If not # set, it is automatically derived. It must point to an actual IP address. # #network.publish_host: 192.168.0.1 # Set both 'bind_host' and 'publish_host': # #network.host: 192.168.0.1 # Set a custom port for the node to node communication (9300 by default): # #transport.tcp.port: 9300 # Enable compression for all communication between nodes (disabled by default): # #transport.tcp.compress: true # Set a custom port to listen for HTTP traffic: # #http.port: 9200 # Set a custom allowed content length: # #http.max_content_length: 100mb # Disable HTTP completely: # #http.enabled: false ################################### Gateway ################################### # The gateway allows for persisting the cluster state between full cluster # restarts. Every change to the state (such as adding an index) will be stored # in the gateway, and when the cluster starts up for the first time, # it will read its state from the gateway. # There are several types of gateway implementations. For more information, see # <http://elasticsearch.org/guide/en/elasticsearch/reference/current/modules-gateway.html>. # The default gateway type is the "local" gateway (recommended): # #gateway.type: local # Settings below control how and when to start the initial recovery process on # a full cluster restart (to reuse as much local data as possible when using shared # gateway). # Allow recovery process after N nodes in a cluster are up: # #gateway.recover_after_nodes: 1 # Set the timeout to initiate the recovery process, once the N nodes # from previous setting are up (accepts time value): # #gateway.recover_after_time: 5m # Set how many nodes are expected in this cluster. Once these N nodes # are up (and recover_after_nodes is met), begin recovery process immediately # (without waiting for recover_after_time to expire): # #gateway.expected_nodes: 2 ############################# Recovery Throttling ############################# # These settings allow to control the process of shards allocation between # nodes during initial recovery, replica allocation, rebalancing, # or when adding and removing nodes. # Set the number of concurrent recoveries happening on a node: # # 1. During the initial recovery # #cluster.routing.allocation.node_initial_primaries_recoveries: 4 # # 2.
