With its comprehensive suite of tools and features, OEM 13c allows you to gain deep insights into the utilization of your CPUs, enabling you to make informed decisions and maintain optimal performance. By leveraging the power of OEM 13c, you can proactively identify and address any issues related to CPU utilization, ensuring the smooth operation of your system.

Understanding CPU Utilization in OEM 13C

CPU utilization is an essential metric for monitoring and managing the performance of your Oracle Enterprise Manager (OEM) 13C environment. By checking CPU utilization, you can identify potential performance bottlenecks, troubleshoot issues, and optimize resource allocation. In this article, we will explore various methods to check CPU utilization in OEM 13C.

Method 1: Using Performance Hub in OEM 13C

OEM 13C provides a comprehensive Performance Hub that allows you to monitor the CPU utilization of your target systems. To check the CPU utilization using Performance Hub, follow these steps:

• Log in to your OEM 13C console.
• Navigate to the Performance page.
• Select the target system you want to monitor.
• Click on the "CPU Utilization" metric.
• View the graph and table displaying the CPU utilization over time.
• Apply any necessary filters or adjustments to the displayed data.

The Performance Hub in OEM 13C not only provides CPU utilization data but also offers various metrics and graphs to analyze the overall performance of your systems.

Method 2: Using Metric Extensions in OEM 13C

Another way to check CPU utilization in OEM 13C is by using metric extensions. Metric extensions allow you to customize your monitoring environment by adding additional metrics and performance data specific to your needs.

To create a metric extension for CPU utilization, follow these steps:

• In the OEM 13C console, navigate to the "Metric Extensions" section.
• Create a new metric extension and specify the target system.
• Add the CPU utilization metric to the extension.
• Configure any additional settings or thresholds.
• Save the metric extension.

Once the metric extension is created, you can monitor the CPU utilization through the custom metric in OEM 13C. This method allows you to define specific thresholds or actions based on your requirements.

Benefits of Using Metric Extensions

Using metric extensions in OEM 13C offers several benefits for monitoring CPU utilization:

• Flexibility to add custom metrics and performance data.
• Better visibility into specific aspects of performance.
• Ability to define thresholds and alerts tailored to your environment.
• Enhanced troubleshooting capabilities for CPU-related issues.

Method 3: Using Command-Line Interface (CLI) in OEM 13C

If you prefer working with the command-line interface (CLI), you can also check CPU utilization in OEM 13C using the 'emcli' command. The 'emcli' command-line interface provides a comprehensive set of commands for managing and monitoring your OEM environment.

To check CPU utilization using the 'emcli' command, use the following syntax:

emcli get_metric_data -target_type="host" -target_name="hostname" -metric="oracle_emd:oracle_emd:CPU_Load:001" -column="Value" -begin_time="yyyy-mm-dd hh:mi:ss" -end_time="yyyy-mm-dd hh:mi:ss"

Replace 'hostname' with the name of the target system and specify the desired time period using 'begin_time' and 'end_time'. This command will return the CPU utilization data for the specified target system within the specified time range.

Benefits of Using the Command-Line Interface

Using the command-line interface for checking CPU utilization in OEM 13C provides several advantages:

• Ability to automate monitoring tasks using scripts or scheduled jobs.
• Faster access to CPU utilization data without navigating through the console.
• Greater control and flexibility for customizing command parameters.

Exploring Additional Methods for CPU Utilization Check

In addition to the methods mentioned above, there are a few more options to check CPU utilization in OEM 13C:

Method 4: Using Enterprise Manager Command Line Interface (EMCLI)

EMCLI is a powerful command-line interface tool provided by OEM 13C. It allows you to perform various administrative tasks, including checking CPU utilization.

To check CPU utilization using EMCLI, use the following command:

emcli get_metric -entity="target_name" -metric="oracle_emd:oracle_emd:host:CPUUtilization" -interval="5" -duration="30"

This command will retrieve the CPU utilization metric data for the specified target within the specified interval and duration.

Method 5: Using Oracle SQL Developer

If you have Oracle SQL Developer installed, you can connect to the Oracle Management Repository (OMR) and query the performance data directly from the database.

To check CPU utilization using Oracle SQL Developer, follow these steps:

• Launch Oracle SQL Developer and connect to the OMR database.
• Execute the following query to retrieve the CPU utilization data:

SELECT
  METRIC_COLUMN,
  VALUE
FROM
  MGMT$METRIC_CURRENT
WHERE
  TARGET_NAME = 'target_name'
  AND METRIC_NAME = 'oracle_emd:host:CPUUtilization'
ORDER BY
  COLLECTION_TIMESTAMP DESC;

Replace 'target_name' with the name of the target system. This query will fetch the most recent CPU utilization data for the specified target.

By utilizing these additional methods, you can further customize your approach to checking CPU utilization in OEM 13C and find the one that best suits your requirements.

In conclusion, monitoring CPU utilization in OEM 13C is crucial for maintaining optimal performance and identifying potential issues. Whether you prefer using the Performance Hub, creating metric extensions, leveraging the command-line interface, or exploring additional methods, OEM 13C offers various avenues to obtain accurate and detailed insights into CPU utilization. Choose the method that aligns with your monitoring needs and gain the visibility necessary to optimize resources, troubleshoot problems, and ensure efficient operation of your systems.
