Apache CouchDB collector

Monitors vital statistics of a local Apache CouchDB 2.x server.

This module monitors one or more CouchDB instances, depending on your configuration.

Metrics

All metrics have "couchdb." prefix.

Metric	Scope	Dimensions	Units
activity	global	db_reads, db_writes, view_reads	requests/s
request_methods	global	copy, delete, get, head, options, post, put	requests/s
response_codes	global	200, 201, 202, 204, 206, 301, 302, 304, 400, 401, 403, 404, 406, 409, 412, 413, 414, 415, 416, 417, 500, 501, 503	responses/s
response_code_classes	global	2xx, 3xx, 4xx, 5xx	responses/s
active_tasks	global	indexer, db_compaction, replication, view_compaction	tasks
replicator_jobs	global	running, pending, crashed, internal_replication_jobs	jobs
open_files	global	files	files
erlang_vm_memory	global	atom, binaries, code, ets, procs, other	B
proccounts	global	os_procs, erl_procs	processes
peakmsgqueue	global	peak_size	messages
reductions	global	reductions	reductions
db_sizes_file	global	a dimension per database	KiB
db_sizes_external	global	a dimension per database	KiB
db_sizes_active	global	a dimension per database	KiB
db_doc_count	global	a dimension per database	docs
db_doc_del_count	global	a dimension per database	docs

Configuration

Edit the go.d/couchdb.conf configuration file using edit-config from the Netdata config directory, which is typically at /etc/netdata.

cd /etc/netdata   # Replace this path with your Netdata config directory, if different
sudo ./edit-config go.d/couchdb.conf

Sample for a local server running on port 5984:

local:
  user: 'admin'
  pass: 'password'
  node: '[email protected]'

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 [email protected] in a cluster, or [email protected] / [email protected] for a single-node server.

If you want per-database statistics, these need to be added to the configuration, separated by spaces:

local:
  databases: 'db1 db2 db3 ...'

For all available options, see the CouchDB collector's configuration file.

Troubleshooting

To troubleshoot issues with the couchdb collector, run the go.d.plugin with the debug option enabled. The output should give you clues as to why the collector isn't working.

• Navigate to the plugins.d directory, usually at /usr/libexec/netdata/plugins.d/. If that's not the case on your system, open netdata.conf and look for the plugins setting under [directories].

  cd /usr/libexec/netdata/plugins.d/

• Switch to the netdata user.

  sudo -u netdata -s

• Run the go.d.plugin to debug the collector:

  ./go.d.plugin -d -m couchdb
