The correct order of steps to create and operate a custom monitor is:

Determine the type and frequency of statistics to collect.

Create a monitor.

Add one or more sinks to the monitor.

Collect statistics.

Gather monitoring files, or monitor output from the console.

To create and operate a custom monitor within the Dell VPLEX environment, follow these steps:

Determine the Type and Frequency of Statistics to Collect: Identify what statistics are relevant for your monitoring purposes and how frequently they should be collected. This will depend on the specific needs of your environment and the performance metrics you wish to track.

Create a Monitor: Using the VPLEX CLI or Unisphere for VPLEX, create a new monitor instance. Configure the monitor with the types of statistics you determined in the previous step.

Add One or More Sinks to the Monitor: Sinks are the destinations where the collected statistics will be sent. These could be files, databases, or external systems. Set up one or more sinks in the monitor configuration to ensure that the data is stored or transmitted as needed.

Collect Statistics: Start the monitor to begin collecting statistics. The monitor will gather data from the VPLEX system according to the type and frequency settings you have specified.

Gather Monitoring Files, or Monitor Output from the Console: After the statistics have been collected, retrieve the monitoring files from the specified sinks, or view the output directly from the console if real-time monitoring is configured.

These steps are based on the standard procedures for setting up and managing custom monitors in a Dell VPLEX environment, as detailed in the Dell EMC VPLEX documentation. By following these steps, you can effectively monitor the performance and health of your VPLEX system.

To increase data protection by converting a local RAID-0 virtual volume to a distributed virtual volume, the recommended method is to create a corresponding device on the remote cluster and then attach it as a mirror to the existing local device. This process effectively creates a distributed virtual volume that spans across both clusters.

Create a Device on the Remote Cluster: Start by creating a new device on the remote VPLEX cluster. This device should be of the same size as the local RAID-0 virtual volume and should not have a virtual volume associated with it1.

Attach as a Mirror: Once the remote device is created, attach it as a mirror to the local RAID-0 virtual volume. This operation is performed using the VPLEX CLI and will begin the process of mirroring the data from the local device to the remote device1.

Synchronization: After attaching the remote device as a mirror, the VPLEX system will synchronize the data between the local and remote devices. This ensures that both devices have identical data and are in a consistent state1.

Distributed Virtual Volume: Once the synchronization is complete, the local and remote devices together form a distributed virtual volume. This volume now has increased data protection because it is distributed across two different clusters1.

Verification: Verify that the distributed virtual volume is functioning correctly by checking its status and ensuring that it is accessible from both clusters1.

Best Practices: It is important to follow the best practices for creating and managing distributed virtual volumes as outlined in the Dell VPLEX Deploy Achievement documents. This includes proper planning, execution, and verification of the mirroring process1.

In summary, the recommended method to change a local RAID-0 virtual volume to a distributed virtual volume is to create a corresponding device on the remote cluster and attach it as a mirror, thereby forming a distributed virtual volume with increased data protection.

The command used to display available statistics for monitoring VPLEX is monitor stat-list. This command provides a list of all the statistics that can be monitored on the VPLEX system.

Command Usage: The monitor stat-list command is executed in the VPLEX CLI (Command Line Interface). When run, it will display a list of all the statistics that are available for monitoring1.

Monitoring Statistics: The statistics available for monitoring can include various performance metrics such as IOPS (Input/Output Operations Per Second), throughput, and latency. These metrics are crucial for assessing the health and performance of the VPLEX system1.

Custom Monitors: In addition to the default system monitors, custom monitors can be created to track specific data. The monitor stat-list command helps in identifying which statistics can be included in these custom monitors1.

Performance Analysis: By using the monitor stat-list command, administrators can determine which statistics are relevant for their performance analysis and can then create monitors to track those specific metrics1.

Documentation Reference: For more information on the usage of the monitor stat-list command and other monitoring commands, administrators should refer to the VPLEX CLI and Administration Guides for the code level the VPLEX is running1.

In summary, the monitor stat-list command is used to display the available statistics for monitoring VPLEX, providing administrators with the information needed to set up and manage performance monitoring on the system.
