Remarks

Consider the following remarks and requirements for this sensor:

Remark

Description

Performance impact

This sensor has a high performance impact. We recommend that you use no more than 200 of this sensor on each probe.

Sufficient account privileges

This sensor requires sufficient privileges for the account that you use for the connection.

i_round_blueUse an account for the connection that has the privileges to see all (or specific) views. We recommend that you use the SYSTEM account if possible, otherwise grant your database administrator the SELECT_CATALOG_ROLE to the account that you use. Without sufficient privileges, you might see the error message ORA-00942: table or view does not exist.

.NET 4.7.2 or later

This sensor requires .NET 4.7.2 or later from Microsoft on the probe system. In a cluster, install it on every cluster node.

i_round_redIf the framework is missing, you cannot create this sensor.

i_square_cyanFor more information, see the Knowledge Base: Which .NET version does PRTG require?

Overprovisioning

This sensor does not support overprovisioning.

Oracle version

This sensor supports Oracle database servers as of version 10.2

IPv6

This sensor supports IPv6.

Lookups

This sensor uses lookups to determine the status values of one or more channels.

Limits

This sensor has predefined limits for several metrics.

Credentials

Define the credentials for database management systems in settings that are higher in the object hierarchy.

Hosted probe

i_podYou cannot add this sensor to the hosted probe of a PRTG Hosted Monitor instance. If you want to use this sensor, add it to a remote probe device.

Basic Sensor Settings

Basic Sensor Settings

The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor:

Setting

Description

Identifier

Enter the Oracle System ID (SID) or the SERVICE_NAME of the database that the sensor connects to. Specify the Identification Parameter below. By default, the sensor uses the SID as the connection string.

i_round_blueYou can find the SID or SERVICE_NAME in the CONNECT_DATA part of the TNSNames.ora file on the Oracle server. For example, a SID can look like this: orcl

Identification Parameter

Define the type of identifier that you want to use to connect to the database:

  • SID (default): Connect to the database instance using the SID as the connection string.
  • SERVICE NAME: Connect to the database instance using the SERVICE_NAME as the connection string.

i_round_blueThe type of identifier that you need to use depends on the configuration of the Oracle server.

Sensor Name Prefix

Define if you want to use the SERVICE_NAME as the prefix for the sensor name:

  • Do not use a prefix for the sensor name (default): Only show the name of the tablespace that this sensor monitors.
  • Use SERVICE_NAME as prefix for the sensor name: Add the SERVICE_NAME to the beginning of the sensor name.

i_round_blueIf you have multiple databases on your Oracle server, use the SERVICE_NAME as the prefix to distinguish the tablespaces that you monitor.

Description

Primary Channel

Select a channel from the list to define it as the primary channel. In the device tree, PRTG displays the last value of the primary channel below the sensor's name. The available options depend on what channels are available for this sensor.

i_round_blueYou can set a different primary channel later by clicking b_channel_primary below a channel gauge on the sensor's Overview tab.

Graph Type

Define how this sensor shows different channels:

  • Show channels independently (default): Show a graph for each channel.
  • Stack channels on top of each other: Stack channels on top of each other to create a multi-channel graph. This generates a graph that visualizes the different components of your total traffic.
    i_round_redYou cannot use this option in combination with manual Vertical Axis Scaling (available in the channel settings).

Stack Unit

This setting is only visible if you select Stack channels on top of each other above.

Select a unit from the list. PRTG stacks all channels with this unit on top of each other. By default, you cannot exclude single channels from stacking if they use the selected unit. However, there is an advanced procedure to do so.

Inherited Settings

By default, all of these settings are inherited from objects that are higher in the hierarchy. We recommend that you change them centrally in the root group settings if necessary. To change a setting for this object only, click b_inherited_enabled under the corresponding setting name to disable the inheritance and to display its options.

i_square_cyanFor more information, see section Inheritance of Settings.

Channel List

i_round_blueWhich channels the sensor actually shows might depend on the target device, the available components, and the sensor setup.
