Configuring the agent to monitor Couchbase

1. Configure /etc/sd-agent/conf.d/couchbase.yaml

init_config:

instances:
- server: http://localhost:8091
user: Administrator
password: password
  • If your DB requires additional authentication, you wish to specify a timeout or fine tune other details, amend the config file as necessary. 

2. Restart the agent

sudo /etc/init.d/sd-agent restart

Verifying the configuration
Execute info to verify the configuration with the following:

sudo /etc/init.d/sd-agent info 

If the agent has been configured correctly you’ll see an output such as:

couchbase
-----
  - instance #0 [OK]
  - Collected 30 metrics & 0 events

Configuring graphs

Click the name of your server from the Devices list in your Server Density account then go to the Metrics tab. Click the + Graph button on the right then choose the Couchbase metrics to display the graphs. The metrics will also be available to select when building dashboard graphs.
