Couchbase

Introduction

Couchbase Server, originally known as Membase, is an open source, distributed NoSQL document-oriented database that is optimized for interactive applications. These applications must service many concurrent users; creating, storing, retrieving, aggregating, manipulating and presenting data. In support of these kinds of application needs, Couchbase is designed to provide easy-to-scale key-value or document access with low latency and high sustained throughput. It is designed to be clustered from a single machine to very large scale deployments.

Couchbase Server provides on-the-wire client protocol compatibility, but is designed to add disk persistence, data replication, live cluster reconfiguration, re balancing and multi tenancy with data partitioning.

Discovery with the agent

Collector Type: Agent

Category: Application Monitors

Application Name: Couchbase

Global Template Name: Linux - Couchbase Monitors

Parameters

Collected Metrics

Discovery using the gateway

The administrator can deploy a gateway to support Couchbase agentless monitoring. The gateway establishes a connection to the database using the management profile, collects metrics from the templates, and starts monitoring.

To monitor Couchbase:

• Associate appropriate database credentials to the discovered database.
• Assign one or more database-specific global templates on the device.

Choose one of the following management mechanisms to discover Couchbase servers and add them to your inventory:

• WMI

• SSH

• SNMP

• (Optional) Manually add a database server to the infrastructure inventory:

  1. Select Infrastructure.
  2. Click the Settings icon.
  3. Select Resource > Add.
  4. In the Add Device window, enter the required Device Type and specify additional fields you want to include.
  5. Click Save.

View resource metrics

The gateway monitors the application using the assigned templates and displays the results in a graphical format. To view resource metrics, click the desired Database Resource Name > Resource Details > Metrics.

Prerequisites

• Install gateway version 5.0.0 or later.
• Database and port(8091) are reachable from the gateway.
• Map a suitable gateway management profile to a resource.
• Create credentials with type Database before assigning a template to a resource. The Port, Connection Time-out, and Is Secure values are not used to create credentials.

Troubleshooting

If the graphs are plotted incorrectly, verify that the resource is accessible and telnet connectivity:

ping <IPAddress>
telnet <IPAddress:Port>

Also, verify that you are using valid credentials for the resource.

Supported templates

• Couchbase - Bucket
• Couchbase - Cluster
• Couchbase - Node
• Couchbase - Query

After selecting the templates, you can:

• Assign Couchbase templates from Setup or at the device level.
• Customize default configuration parameter values while assigning the template.
