+# elasticsearch
+
+This module monitors Elasticsearch performance and health metrics.
+
+It produces:
+
+1. **Search performance** charts:
+ * Number of queries, fetches
+ * Time spent on queries, fetches
+ * Query and fetch latency
+
+2. **Indexing performance** charts:
+ * Number of documents indexed, index refreshes, flushes
+ * Time spent on indexing, refreshing, flushing
+ * Indexing and flushing latency
+
+3. **Memory usage and garbace collection** charts:
+ * JVM heap currently in use, committed
+ * Count of garbage collections
+ * Time spent on garbage collections
+
+4. **Host metrics** charts:
+ * Available file descriptors in percent
+ * Opened HTTP connections
+ * Cluster communication transport metrics
+
+5. **Queues and rejections** charts:
+ * Number of queued/rejected threads in thread pool
+
+6. **Fielddata cache** charts:
+ * Fielddata cache size
+ * Fielddata evictions and circuit breaker tripped count
+
+7. **Cluster health API** charts:
+ * Cluster status
+ * Nodes and tasks statistics
+ * Shards statistics
+
+8. **Cluster stats API** charts:
+ * Nodes statistics
+ * Query cache statistics
+ * Docs statistics
+ * Store statistics
+ * Indices and shards statistics
+
+### configuration
+
+Sample:
+
+```yaml
+local:
+ host : 'ipaddress' # Server ip address or hostname
+ port : 'password' # Port on which elasticsearch listed
+ cluster_health : True/False # Calls to cluster health elasticsearch API. Enabled by default.
+ cluster_stats : True/False # Calls to cluster stats elasticsearch API. Enabled by default.
+```
+
+If no configuration is given, module will fail to run.

+# netdata python.d.plugin configuration for elasticsearch stats
+#
+# This file is in YaML format. Generally the format is:
+#
+# name: value
+#
+# There are 2 sections:
+# - global variables
+# - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# update_every: 1
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.
+# If unset, the default for python.d.plugin is used.
+# priority: 60000
+
+# retries sets the number of retries to be made in case of failures.
+# If unset, the default for python.d.plugin is used.
+# Attempts to restore the service are made once every update_every
+# and only if the module has collected values in the past.
+# retries: 60
+
+# autodetection_retry sets the job re-check interval in seconds.
+# The job is not deleted if check fails.
+# Attempts to start the job are made once every autodetection_retry.
+# This feature is disabled by default.
+# autodetection_retry: 0
+
+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. JOBS with the same name
+# are mutually exclusive. Only one of them will be allowed running at
+# any time. This allows autodetection to try several alternatives and
+# pick the one that works.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+# name: myname # the JOB's name as it will appear at the
+# # dashboard (by default is the job_name)
+# # JOBs sharing a name are mutually exclusive
+# update_every: 1 # the JOB's data collection frequency
+# priority: 60000 # the JOB's order on the dashboard
+# retries: 60 # the JOB's number of restoration attempts
+# autodetection_retry: 0 # the JOB's re-check interval in seconds
+#
+# Additionally to the above, elasticsearch plugin also supports the following:
+#
+# host: 'ipaddress' # Server ip address or hostname.
+# port: 'port' # Port on which elasticsearch listen.
+# cluster_health: False/True # Calls to cluster health elasticsearch API. Enabled by default.
+# cluster_stats: False/True # Calls to cluster stats elasticsearch API. Enabled by default.
+#
+#
+# if the URL is password protected, the following are supported:
+#
+# user: 'username'
+# pass: 'password'
+#
+# ----------------------------------------------------------------------
+# AUTO-DETECTION JOBS
+# only one of them will run (they have the same name)
+#
+local:
+ host: '127.0.0.1'
+ port: '9200'
