Couchbase monitoring with Netdata
Couchbase is an open source, distributed, JSON document database. It exposes a scale-out, key-value store with managed cache for sub-millisecond data operations, purpose-built indexers for efficient queries and a powerful query engine for executing SQL-like queries.
Charts#
In this module 8 charts are supported because we collect basic stats from couchbase.
Buckets Basic Stats#
Collected from /pools/default/buckets endpoint.
- Quota Percent Used Per Bucket in
% - Operations Per Second Per Bucket in
ops/s - Disk Fetches Per Bucket in
fetches - Item Count Per Bucket in
items - Disk Used Per Bucket in
bytes - Data Used Per Bucket in
bytes - Memory Used Per Bucket in
bytes - Number Of Non-Resident Items Per Bucket in
items
Configuration#
Edit the go.d/couchbase.conf configuration file using edit-config from the
Netdata config directory, which is typically at /etc/netdata.
To add a new endpoint to collect metrics from, or change the URL that Netdata looks for, add or configure the name and
url values. Endpoints can be both local or remote as long as they expose their metrics on the provided URL.
Here is an example with two endpoints:
For all available options, see the Couchbase collector's configuration file.
Troubleshooting#
To troubleshoot issues with the couchbase, run the go.d.plugin with the debug option enabled. The output should give
you clues as to why the collector isn't working.
First, navigate to your plugins directory, usually at /usr/libexec/netdata/plugins.d/. If that's not the case on your
system, open netdata.conf and look for the setting plugins directory. Once you're in the plugin's directory, switch
to the netdata user.
You can now run the go.d.plugin orchestrator to debug the collector:
