Couchbase Monitoring

Couchbase server is an open source, distributed, document-oriented NoSQL database that supports massive data storage and management with increased flexibility and scalability as compared to traditional databases. The performance of databases defines the success of organizations in providing the 24x7 level of customer satisfaction and smooth operations of day to day business activities. Couchbase Database Monitor helps you to monitor the performance of database and provide extensive information so that necessary steps can be taken before a breakdown of vital business processes occurs.

Configuring AppPerfect Agentless Monitor to monitor Couchbase Server

Following steps will explain how you can configure AppPerfect for Monitoring Couchbase Database Resources:

  1. Once you are logged into the Monitor Server you can see the Web-UI from which you can access all the features of the Monitor Server. Click the Monitors link from the top navigation bar. This will take you to Monitors tab. Click on Add button to Add a New NoSQL Monitor.
  2. Next Step is to define the NoSQL Monitor. Provide the IP Address or Host Name of the target database server which needs to be monitored.
  3. Select the NoSQL Monitor Type from the drop down. AppPerfect can monitor NoSQL databases such as Couchbase, CouchDB, MongoDB, Cassandra for performance and robustness. Select the monitor type which suits your requirement.
  4. Specify a meaningful identifier for the monitor which will help identify the monitor in future.
  5. Specify the Data Fetch Interval which represents the time interval for which application should wait before fetching the monitoring data from the device. Monitoring Data will be fetched after every specified fetch interval. The smaller the time interval, the more granular the data. However, smaller time intervals also result in a much larger data set.
  6. You can specify if the monitor should be Active as soon as its added or should it be in suspended state.
  7. Next Option is to provide database specific configuration settings. Provide scheme, username, password and port number on which database server is running. Once you are done providing the database settings, click on Validate Connection button to confirm that Couchbase database is accessible.

  11. Next step shows the Defining Rules view. This view will provide a list of all numeric attributes. You can select the attributes for which you want to add a rule. A rule is defined as a conditional or threshold value which when exceeds, a notification would be sent. In a typical workflow the monitors extract data from the monitored device and send it to the rules engine. The rules engine evaluates the data to ensure no rule is violated and then sends it to the view manager. However, if a rule is violated, a message is immediately sent to the notification server to alert the user about the rule violation.Rules can be defined at a later stage as well. For details on how you can add/edit rules for the monitor, please see the Rules chapter.
  12. Next step shows the Security & Notification settings. When a rule is violated a notification is sent out to all the concerned users that a particular event has occurred and needs to be dealt with. This process is called notification. AppPerfect provides five modes of notification. They are Email notification, SMS notification, Custom notification, Log notification, Database notification, SNMP Trap notification. For details on each of the supported notification , please see the Notification chapter. In this view you can configure the type of notification which should be sent on Rule violation, Users/Groups to whom notification should be sent and also the subject and details on the notification message.
  13. Click on finish button. We are done adding the monitor for Couchbase Database Monitoring. Once Database Monitor is added, you will get a message Database Monitor added successfully. Now go to Status. Expand the data for IP provided in IP Address while creating the monitor. Expand Couchbase Monitor. Click on + icon against the charts that you want to monitor in your Dashboard.
