Using Pure Storage KM for PATROL

Disabling Volumes Monitoring

Discovering and collecting volumes metrics are resource-intensive actions that can create extra workload on the PATROL Agent and the targeted system. Because the performance of Pure Storage KM for PATROL will be degraded when monitoring systems with more than 500 volumes, Sentry Software recommends disabling the monitoring of all volumes if this information is not required.

To disable volumes monitoring:

1. Right-click the Pure Storage storage system icon > KM Commands > Disable Volumes Monitoring…

   

2. Select Disable Volumes Monitoring and click OK.

Discovery and collect requests and operations are no longer performed. Volumes no longer appear in the PATROL Console.

To resume volumes monitoring, perform the steps above, uncheck the “Disable Volumes Monitoring” box and click “OK”.

Pausing/Resuming Monitoring

In order to perform certain tasks, such as maintenance for example, it is often useful to pause the monitoring of an element or a group of elements. To pause the monitoring of a specific element or group of elements, right-click the element (or element container) icon > KM Commands > Pause Monitoring. When in paused state, the element/group of elements is displayed with an OFFLINE status in the PATROL Console. Additionally, the mention ‘(Suspended)’ appears beside each related parameter.

To resume the monitoring of the element/group of elements, right-click the element (or element container) icon > KM Commands > Resume Monitoring in the menu.

Removing Device Monitoring

Whenever the supervision of an element/group of elements becomes irrelevant, it is possible to terminate its monitoring by right-clicking the element icon > KM Commands > Remove.

Once removed, the element/group of elements is no longer displayed in the PATROL Console. The Remove KM Command only prevents the display of instances in the PATROL Console. The discovery and collect processes are still performed in the background.

Restoring Monitoring

It is possible to restore the monitoring of a device with Pure Storage KM for PATROL after it has been removed from monitoring environment through the Remove option. To see the list of the removed devices or to restore the monitoring of a specific device:

1. Right-click the KM main icon > KM commands > KM Settings > Additional Settings > Restore Monitoring…

   

2. Select:

   • <ALL> if you want to restore the monitoring of all the devices that have been previously removed in the PATROL Console
   • One or more objects if you only want to restore specific devices (press down the Ctrl-key to allow multiple selection)
3. Click Restore.

Generating Activity Reports

Pure Storage KM for PATROL enables you to generate activity reports for:

• Storage systems
• Volumes

To generate an activity report:

1. Right-click the KM main icon or the component instance > KM Commands > Reporting and then the report you wish to obtain.
2. Select the parameter for which you wish to generate a report for (e.g.: transfer bytes traffic).
3. Select the report range and interval.
4. (Optional) Press the components Selection button and select the specific component(s) you wish to include in the report.
5. Click Show Report.

Generating the LUNs Mapping Table

Over time, as servers connected to a SAN get decommissioned, administrators find an increasing number of unmapped LUNs that are no longer used by any server. These LUNs, while unused, still occupy disk space in the disk array. To identify such unmapped LUNs and reclaim the disk space uselessly consumed by these LUNs, administrators can use the LUNs Mapping Table.

1. In the console, right-click the KM main icon or the storage system icon > KM Commands > Reporting > LUNs Mapping Table…

   

2. Select the type of LUNs you wish the list to display: Not Mapped, Mapped or All

3. Select the sorting order: Storage System, Hostname, Host WWN/IQN, LUN, Ports or Size
4. Select the format: Standard or CSV
5. Click Show Report to display a list of LUNs corresponding to your requirements.

Whether a LUN is actually mapped or not is also shown in the InfoBox of each volume instance.

Generating the Per Host Storage Allocation Report

The Per Host Storage Allocation reports on the amount of storage allocated to each monitored host.

1. In the console, right-click the KM main icon or storage system icon > KM Commands > Reporting > Per Host Storage Allocation…
2. The report shows the total amount of consumed and subscribed storage capacity for each monitored host.

Generating the Per LUN Storage Allocation Report

The Per LUN Storage Allocation reports on the amount of storage allocated to each monitored LUN.

1. In the console, right-click the KM main icon or storage system icon > KM Commands > Reporting > Per LUN Storage Allocation…
2. The report shows the total amount of consumed and subscribed storage capacity for each monitored LUN.

The list of results will be truncated in large environments if the buffer size is not sufficient to display all the LUNs available. Refer to the BMC documentation to know how to change the buffer size.

Scheduling Reports

Administrators can generate activity and LUNs Mapping Table reports every day at a specific time.

To schedule reports:

1. Right-click the KM main icon > KM Commands > Reporting > Reports Scheduling. Reports Scheduling wizard appears:

   

2. Specify the time when the reports are automatically generated

3. Check the Activity report type to automatically generate the following reports:
   • Storage systems: Reports on Transfer, Read and Writes Bytes for all monitored storage systems
   • Volumes: Reports on Transfer, Read and Writes Bytes for all monitored volumes

4. Select LUNs Mapping Table to list mapped and unmapped LUNs. The .csv file generated for this report consists in the following comma-separated data: Storage System, Hostname, Host WWN/IQN, LUN, Ports or Size.

5. Click OK.

The generated file(s) are time-stamped and stored in %PATROL_HOME%\log for the specific time set through the History Retention Period parameter.

Refreshing Parameters

To manually refresh parameters without waiting for an automatic polling cycle, right-click the Pure Storage system icon > Refresh Parameters.

Triggering a KM Discovery

Pure Storage KM for PATROL automatically executes a discovery every hour of all objects for the monitored system. This enables discovering and then monitoring any new object added or removed.

You can also force a discovery manually by right-clicking on the KM main icon > KM Commands > Trigger a KM Discovery.
