+# couchdb
+
+This module monitors vital statistics of a local Apache CouchDB 2.x server, including:
+
+* Overall server reads/writes
+* HTTP traffic breakdown
+ * Request methods (`GET`, `PUT`, `POST`, etc.)
+ * Response status codes (`200`, `201`, `4xx`, etc.)
+* Active server tasks
+* Replication status (CouchDB 2.1 and up only)
+* Erlang VM stats
+* Optional per-database statistics: sizes, # of docs, # of deleted docs
+
+### Configuration
+
+Sample for a local server running on port 5984:
+```yaml
+local:
+ user: 'admin'
+ pass: 'password'
+ node: 'couchdb@127.0.0.1'
+```
+
+Be sure to specify a correct admin-level username and password.
+
+You may also need to change the `node` name; this should match the value of `-name NODENAME` in your CouchDB's `etc/vm.args` file. Typically this is of the form `couchdb@fully.qualified.domain.name` in a cluster, or `couchdb@127.0.0.1` / `couchdb@localhost` for a single-node server.
+
+If you want per-database statistics, these need to be added to the configuration, separated by spaces:
+```yaml
+local:
+ ...
+ databases: 'db1 db2 db3 ...'
+```

+# netdata python.d.plugin configuration for couchdb

+# 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.
+# By default, CouchDB only updates its stats every 10 seconds.
+update_every: 10
+
+# 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
+
+# penalty indicates whether to apply penalty to update_every in case of failures.
+# Penalty will increase every 5 failed updates in a row. Maximum penalty is 10 minutes.
+# penalty: yes
+
+# 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
+# penalty: yes # the JOB's penalty
+# autodetection_retry: 0 # the JOB's re-check interval in seconds
+#
+# Additionally to the above, the couchdb plugin also supports the following:
+#
+# host: 'ipaddress' # Server ip address or hostname. Default: 127.0.0.1
+# port: 'port' # CouchDB port. Default: 15672
+# scheme: 'scheme' # http or https. Default: http
+# node: 'couchdb@127.0.0.1' # CouchDB node name. Same as -name vm.args argument.
+#
+# if the URL is password protected, the following are supported:
+#
+# user: 'username'
+# pass: 'password'
+#
+# if db-specific stats are desired, place their names in databases:
+# databases: 'npm-registry animaldb'
+#
+# ----------------------------------------------------------------------
+# AUTO-DETECTION JOBS
+# only one of them will run (they have the same name)
