Couchbase Integration
Couchbase Server is an open-source, distributed multi-model NoSQL database. This integration installs and configures Telegraf to send Couchbase metrics into Wavefront. Telegraf is a light-weight server process capable of collecting, processing, aggregating, and sending metrics to a Wavefront proxy.
In addition to setting up the metrics flow, this integration also installs a dashboard.
To see a list of the metrics for this integration, select the integration from https://github.com/influxdata/telegraf/tree/master/plugins/inputs.
Couchbase Setup
This integration uses the Couchbase input plugin for Telegraf.
Step 1. Install the Telegraf Agent
This integration uses the Couchbase input plugin for Telegraf. If you’ve already installed Telegraf on your server(s), you can skip to Step 2.
Log in to your product instance and follow the instructions on the Setup tab to install Telegraf and a Wavefront proxy in your environment. If a proxy is already running in your environment, you can select that proxy and the Telegraf install command connects with that proxy. Sign up for a free trial to check it out!
Step 2: Edit the Wavefront Output Plugin
Comment out the source_override property in the Wavefront output plugin.
Step 3. Configure Couchbase Input Plugin
Create a file called couchbase.conf in /etc/telegraf/telegraf.d and enter the following snippet:
# Read per-node and per-bucket metrics from Couchbase
[[inputs.couchbase]]
## specify servers via a url matching:
## [protocol://][:password]@address[:port]
## e.g.
## http://couchbase-0.example.com/
## http://admin:secret@couchbase-0.example.com:8091/
##
## If no servers are specified, then localhost is used as the host.
## If no protocol is specifed, HTTP is used.
## If no port is specified, 8091 is used.
servers = ["http://<username>:<password>@<your.couchbase.server>:8091"]
Replace your.couchbase.server with the IP of your Couchbase instance. Replace username and password with your instance’s username and password.
To monitor multiple Couchbase server instances, configure the servers parameter with address of your Couchbase servers.
servers = ["http://<username>:<password>@<your.couchbase.sever1>:8091", "http://<username>:<password>@<your.couchbase.sever2>:8091"]
Step 4. Restart Telegraf
Run sudo service telegraf restart to restart your Telegraf agent.
