What's New

Disable Virtual Disks Monitoring: This new feature allows administrators to disable themonitoring of all the virtual disks of a system in order to limit the number of instancescreated and therefore reduce the system resource consumption.

New parameters:

The Write Retries Byte Rate parameter is now available for the Data Replication Tunnelsapplication class, to report on the write actions that had to be retransmitted during thesample interval in response to a failed write transaction.

The Time Since Last Activity parameter has been added to the Virtual Disks applicationclass to report on the number of days since any activity occurred on the virtual disk.

Port Count: this parameter has been added to the Nodes application class to report on thenumber of fiber and Ethernet ports available in the node.

Changes and Improvements

Better integration with BMC ProactiveNet Performance Management: Application Classesand Key Performance Indicators are now automatically enabled and set when importing aBMC Portal adapter into BMC ProactiveNet.

Fixed Issues

A syntax error prevented the upgrade from the previous version to be processed.

The product could not access the file content generated by the process "evapref.exe"running on Windows 2008 server since this file was already handled by another process. As aresult, the product could not collect information and the parameter "Application CollectionStatus" displayed the following error message: "Problem: SSSU.exe not responding:SentrySoftware-SEN_EVA_Main".

Integrating with BMC ProactiveNetPerformance ManagementOverview

To integrate a Performance Manager into BMC ProactiveNet, you need to first install andconfigure the solution in BMC Portal, automatically enable the application classes and create aspecific adapter. An adapter for BMC Portal facilitates pulling of performance data from existingBMC Portal solutions into BMC ProactiveNet. Using an Adapter, you can import BMC Portalapplication classes (provided in a Performance Manager – PM) into BMC ProactiveNet. TheAdapter periodically synchronizes the performance data collected by these application classesinto BMC ProactiveNet.

Adapter for BMC PATROL Architecture

Automatically Enabling the ApplicationClassesTo automatically enable application classes:

1. Uncompress the BPM-Express-for-HPEVA-<version>-PM2BPPM.zip file

2. Copy all the BPM_SENTRYSOFTWARE_HPEVA_SOLUTIONSEN_HPEVA_MAIN xml files into:<BPPM install dir>\ProactiveNet\pw\pronto\systdata\adapter-defaults

3. Restart the BMC ProactiveNet server

You will then have to create and import an adapter for a BMC Portal PM

Managing Baselines and Key PerformanceIndicatorsIn order to facilitate the detection of abnormalities on your monitored environment, BMCProactiveNet calculates baselines per parameter (metrics or attributes) based on valuescollected over a specified period of time to determine a normal operating range. When thecollected values for these parameters are out of range, an alert is triggered.

Some parameters are identified by default as Key Performance Indicators and thereforeautomatically included in the base lining calculation.

Managing baselines

The baseline is the expected normal operating range for a metric or attribute of a monitor.

The baseline is calculated by collecting the values for a monitor’s attributes and metrics over aspecified time period and establishing a low baseline value (consisting of the 10th percentile ofall the values for a given time period) and a high baseline value (consisting of the 90th percentileof all the values for a given time period), taking a weighted average of these values over time. Ahigher weight is given to the latest data being factored into the baseline average. The accuracy ofthe baseline improves over time.

Requirements for baseline generation

For baselines to be generated for an attribute, that abnormality threshold means that thethreshold exists and is not suppressed. Additionally, if the Key Performance Indicator (KPI) mode is active, only those attributes thathave an active abnormality threshold and are also KPI attributes will have baselines generatedfor them.

Absolute thresholds (with "outside baseline") or signature thresholds do not satisfy these requirements.

Managing Key Performance Indicators

The KPI attribute of a parameter can be activated or deactivated manually through the BMCProactiveNet Administration Console. In this PM, some parameters or attributes have beendesignated as important indicators of performance (KPIs). We do not recommend that thesedefault settings are modified.

However, advanced users may activate or deactivate KPIs from the BMC ProactiveNet

To add or remove Key Performance Indicator (KPI) attributes for a monitor type

1. In the Administration Console, from the menu bar, choose Tools > KPI Administration. TheKPI Administration dialog box is displayed.

2. From the Monitor Type list, choose the monitor type for which you want to add or removeKPI attributes. A list of attributes for the selected monitor type is displayed.

3. In the KPI column for the attributes that you want to add or remove as Key PerformanceIndicators:

select the KPI check box to add the corresponding attribute as a KPI

deselect the KPI check box to remove the corresponding attribute from the KPIs for thatmonitor type

BMC Performance Manager Express for HP EVA monitors all of the performance metrics andusage statistics of your HP EVA disk arrays, such as file disk space usage, storage controllerutilization, I/Os on the disks/controllers/volumes, etc. It continuously monitors the activity ofeach array and is also able to build reports on past utilization statistics.

To setup a complete monitoring of the array, we strongly recommend you to also use BMCPerformance Manager Express for Hardware that covers all the physical aspect of the HP EVAhardware (status of the disks, ports, temperature, power supplies, power consumption, etc).

This chapter explains how to use each monitoring tool i.e. a separate application class within theBMC Performance Manager Express for HP EVA by Sentry Software solution.

BMC Performance Manager Express for HP EVA is a Performance Manager specifically designed for BMCPortal; consequently, it uses the same common features and procedures of BMC® Portal. This documentassumes that the user knows how to use the Portal and therefore explains procedures only related toBMC Performance Manager Express for HP EVA, and not on how to add Elements, Element Profiles etc.Please refer to the BMC Portal documentation for details on how to use the Portal.

Viewing the Overall Activity of a DiskArrayEach disk array connected to and managed by the Storage Server is represented by a node objectwith two parameters which provide an overall view of the activity of the corresponding array: Request Rate and Byte Rate.

Selecting Disk Arrays' Parameters

In case of slow response times experienced by the hosts, these parameters are the first ones tocheck to verify if the bottleneck is at the level of the disk array (instead of the HBA, the fiberswitch, etc.).

Viewing a Controller's Processor Utilization as a Graph

A processor utilization over 80% means that this controller is overloaded and that the controllerconstitutes a bottleneck for the disk array. Also, it is also usually considered that a processoraverage utilization above 50% on both controllers constitutes an important risk as one singlecontroller wouldn't be able to handle the entire load of the disk array in case of a controller failover. That's why a warning threshold is set at 50%.

Detecting Unbalanced WorkloadDistribution on ControllersA storage controller manages the flow of information between the server and the data, assigningtwo paths, in case one of the paths fails or is overloaded. For the best levels of performance andavailability, every layer of technology must be balanced.

Compare the Processor Utilization of your Controllers

1. In the console, double-click the Processor Utilization parameter of the first controller forwhich you need to compare the activity. A graph is automatically displayed in the graphpane.

2. Select the Processor Utilization parameter of the second controller and drag it from the treeview of the Operator tab to the graph. The second parameter is automatically added to thefirst one to facilitate the comparison. Compare the values to evaluate the workloaddistribution.

Comparing Controllers Processor Utilization

For example, if the processor utilization on one controller goes above 80% while the othercontroller stays almost idle, it indicates that one on the controllers constitutes a bottleneck forthe disk array that could be alleviated by better sharing the load between the controllers.

Administrators should pay close attention to which logical drive is handled by which controller,depending on the activity of this logical drives to be able to reallocate controller to drive I/Oactivity so that neither controller is overloaded. The activity of logical drives is monitored withthe Virtual Disk application class.

Diagnosing Fiber Performance IssuesEach external data port is represented by a Host Port Statistics instance. The parameters of thisclass provide an accurate picture of the traffic on each fiber link. This will notably helpadministrators identify which port constitutes a bottleneck or diagnose 'multi-pathing' issues.

1. Create a graph with the Read Byte Rate and Write Byte Rate parameters to visualize thetraffic on each fiber port (host ports only). In the console, double-click a Controller's icon >Host Port Statistics > Fiber Ports > Read Byte Rate to create a graph with the Read Byte Ratevalue.

Diagnosing a Bad Disk LayoutA non-optimal physical disk layout can cause one single physical disk to become the bottleneckof a SAN. To verify that the I/Os are well-balanced across all physical disks you can check the Read Byte Rate and Write Byte Rate parameters of each physical disk and make sure they havesimilar average values.

Verify Physical Disks Workload Distribution

Diagnosing Slow Fiber PerformanceBad link configuration can severely degrade the performance of a SAN. A misconfigured fiber linkcan force the ports (typically for disk array and switches) to repeatedly re-emit the signal in orderto properly perform the data transmission.

The Port Status class reports on the various types of errors encountered by each port allowingSAN administrators to identify the exact symptoms of a slow fiber link, and thus figure out theroot cause leading to the array slow performance.

Slow Fiber Performance

Look carefully at each of the Port Status class parameters. Any growing value needs to bereported to the SAN administrator in charge of the configuration of the fiber switches.

Protection Level IssuesA physical disk group is configured with a certain level of protection against disk failures. This iscalled the Requested Protection Level and can be set to the following values:

None

Single

Double

When a physical disk group lacks storage space to provide the requested protection level, theactual protection level will be lower. SAN administrators will want to ensure the actualprotection level matches their internal policy.

The Protection Level parameter of the Physical Disk Groups class displays the actual andrequested protection levels. This parameter will trigger a warning when the actual protectionlevel is lower than the requested protection level. In case of a warning, SAN administrators willneed to add disks to the physical disk group to restore the data protection level.

A VRAID0 virtual disk hosted on a physical disk group with a protection level set to None will lose all ofits data upon a disk failure.

Verifying the Activity Generated by aLUNIn order to understand the high activity of a disk array, it is important to identify the LUNs (orvirtual disks in HP EVA terminology) generating the heaviest I/Os. The array administrator canthen check with the system administrator whether the reported activity may be considered anormal behavior.

The Read Byte Rate and Write Byte Rate parameters of the Virtual Disk instances expose the datathroughput for each LUN, while parameters such as Cache Read Data Rate, Flush Byte Rate, MirrorByte Rate, and Prefetch Byte Rate provide more in-depth details about the data traffic associatedwith each LUN.

LUN Activity

When the system or application that relies on a LUN experiences slow response times, it maybecome interesting to compare the Read Response Time and Write Response Time parametersof the LUN with different instances of the Virtual Disk class to see whether the LUN actuallydelivers slower performance than the other LUNs.

Enabling the Debug ModeBy default, BMC Performance Manager Express for HP EVA sends only the most criticalinformation, warning and error messages to the Application Collection Status parameter. Mostoften, this information is accurate enough to ensure that BMC Performance Manager Express forHP EVA is functioning properly. If you encounter an issue and wish to report it to customersupport, you will be asked to enable the Debug Mode and provide the debug output to thesupport team.

1. In the Configure tab > click the Element whose debug output you require.

2. Scroll down to Application Classes > click the Application class for which you want to enablethe debug mode > click Edit.

3. Select Yes from the drop-down Debug Mode list > Save.By default, BMC Performance Manager Express for HP EVA sends its debug output to: %RSM_HOME%/RSM(xx)/SEN_EVA/sen_eva_debug_hostname.log".

4. Wait for 15 minutes and then disable the debug mode by selecting No.

5. Send the debug file to the support team.

Pay attention to the f ile size -the debug output of BMC Performance Manager Express for HP EVA could bevery large if enabled for several days

Disabling Virtual Disks MonitoringBy default, the solution discovers and monitors all virtual disks in the HP EVA storage systems.Discovering and collecting disks metrics are resource-intensive actions that can create extraworkload on the targeted system. To limit the number of instances created and therefore reducethe system resource consumption, administrators can disable the monitoring of all the virtualdisks of a system.
