Oracle Database monitoring configuration

After you define the scope of your configuration, you need to identify the network devices you'd like to collect data from and identify the ActiveGates that will execute the extension and connect to your devices.

Make sure that all the ActiveGates from the ActiveGate group you'll define as the scope can connect to a respective data source. You can assign an ActiveGate to a group during or after installation. For more information, see ActiveGate group.

The monitoring configuration is a JSON payload defining the connection details, credentials, and feature sets that you want to monitor. For details, see Start monitoring.

Example payload to activate an Oracle SQL extension:

jsoncopydownload
[
  {
    "value": {
      "enabled": true,
      "description": "My Oracle SQL extension",
      "version": "0.1.1",
      "featureSets": [
        "io",
        "cpu",
      ],
      "sqlOracleRemote": {
        "licenseAccepted": true,
        "endpoints": [
          {
            "host": "sqlserver.org",
            "port": 1521,
            "databaseIdentifier": "serviceName",
            "authentication": {
              "scheme": "basic",
              "username": "admin",
              "password": "password"
            },
            "serviceName": "some-serviceName"
          }
        ]
      }
    },
    "scope": "ag_group-default"
  }
]

When you have your initial extension YAML ready, package it, sign it, and upload it to your Dynatrace environment. For details, see Manage extension lifecyle.

The Dynatrace Hub-based extension activation wizard contains a dynamically updated JSON payload with your monitoring configuration

You can also use the Dynatrace API to download the schema for your extension that will help you create the JSON payload for your monitoring configuration.

Use the GET an extension schema endpoint.

Issue the following request:

bashcopydownload
curl -X GET "{env-id}.live.dynatrace.com/api/v2/extensions/{extension-name}/{extension-version}/schema" \
   -H "accept: application/json; charset=utf-8" \
   -H "Authorization: Api-Token {api-token}"

Make sure to replace {extension-name} and {extension-version} with values from your extension YAML file. A successful call returns the JSON schema.

Scope

Note that each ActiveGate host running your extension needs the root certificate to verify the authenticity of your extension. For more information, see Sign extension.

The scope is an ActiveGate group that will execute the extension. Only one ActiveGate from the group will run this monitoring configuration. If you plan to use a single ActiveGate, assign it to a dedicated group. You can assign an ActiveGate to a group during or after installation. For more information, see ActiveGate group.

Use the following format when defining the ActiveGate group:

jsoncopydownload
"scope": "ag_group-<ActiveGate-group-name>",

Replace <ActiveGate-group-name> with the actual name.

Version

Version of this monitoring configuration. Note that a single extension can run multiple monitoring configurations.

Description

Human-readable description of the specifics of this monitoring configuration.

Enabled

If set to true, the configuration is active and Dynatrace starts monitoring immediately.

Endpoints

You can define up to 100 endpoints in a single monitoring configuration in the SQLOracleRemote section.

jsoncopydownload
"sqlOracleRemote": {
    "licenseAccepted": true,
    "endpoints": [
      {
        "host": "sqlserver.org",
        "port": 1521,
        "databaseIdentifier": "serviceName",
        "authentication": {
          "scheme": "basic",
          "username": "admin",
          "password": "password"
        },
        "serviceName": "some-serviceName"
      }
    ]
  }
}

Oracle JDBC Driver

The Oracle SQL data source requires the Oracle JDBC driver distributed by Dynatrace. By setting the licenceAccepted property to true, you indicate that you have read and accepted the Dynatrace redistribution license agreement for Oracle JDBC Driver.

To define an Oracle Database server, add the following details in the endpoints section:

• Host
• Port
• Database identifier, either serviceName or sid.
• Authentication credentials

Authentication

Authentication details passed to the Dynatrace API when activating monitoring configuration are obfuscated and it's impossible to retrieve them.

Feature sets

Add a list of feature sets you want to monitor. To report all feature sets, add all.

jsoncopydownload
"featureSets": [
  "cpu",
  "io"
  ]

Resource consumption

Resource consumption depends on the number of Oracle endpoints. The first endpoint consumes 110 MB of RAM and 0.1%–0.5% of CPU. Every following endpoint consumes 0.5–1.0 MB of RAM and ~0.01% of CPU.
