<%NUMBERING1%>.<%NUMBERING2%>.<%NUMBERING3%> PRTG Manual: Oracle Tablespace Sensor

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.

• Use 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.

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

For 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

You 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.

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.

You 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.

The 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: 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.

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

Tablespaces

The tablespace that this sensor monitors.

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.

You can set a different primary channel later by clicking 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.
  You 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.

Downtime

In the channel table on the Overview tab, this channel never shows any values. PRTG uses this channel in graphs and reports to show the amount of time in which the sensor was in the Down status

Free Blocks
