Apache CouchDB

Introduction

CouchDB is an open-source document-oriented NoSQL database, implemented in Erlang. It uses multiple formats and protocols to store, transfer, and process data. CouchDB uses JSON to store data, JavaScript as its query language using MapReduce, and HTTP for an API.

Discovery with the agent

Collector Type : Agent

Category : Application Monitors

Application Name : CouchDB

Global Template Name : LINUX CouchDB Template

Parameters

Note: All field attributes are mandatory, use default values wherever applicable.

Collected Metrics

Discovery using the gateway

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

To monitor CouchDB:

• 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 CouchDB 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 any additional fields you want.
  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 higher.
• Map a suitable gateway management profile to a resource.
• Create credentials with type HTTP 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

After selecting the templates, you can:

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