PAN pNode Performance Test

The PAN architecture was designed around simplifying pServer management and monitoring. A pServer is a logical server that possesses all the resources of a conventional server, but which is not tied to a specific processing resource. In PAN Manager, these processing resources are called Processing Nodes, or simply pNodes.

This test reports the current status of each pNode in this PAN Domain and also helps the administrator to determine the following:

  • the speed of the CPU in the pNode;
  • the number of sockets, CPU cores, vNICs and vHBAs available in this pNode;
  • the size of the RAM in each CPU;
  • Which type of pool i.e., global or local does the pNode belong to?
  • The temperature of the pNode and its core components such as CPU, memory, hard drive, system board, etc.

Target of the test : An Egenera PAN Manager

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each pNode in the PAN manager being monitored.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.

Host

The IP address of the Egenera PAN Manager for which this test is to be configured.

PAN Manager User, PAN Manager Password, and Confirm Password

To monitor the Egenera PAN Manager, the eG agent has to be configured with administrator privileges. This is why, you need to specify the credentials of an administrator against the PAN Manager User and PAN Manager Password parameters of this test. Confirm the pan manager password by retyping it in the Confirm Password text box.

SSL

By default, the Egenera PAN Manager is not SSL-enabled. Accordingly, the SSL flag is set to No by default.

PAN Manager Webport

By default, in most environments, the Egenera PAN Manager listens on port 80 (if not SSL-enabled) or on port 443 (if SSL-enabled) only. This implies that while monitoring the Egenera PAN Manager, the eG agent, by default, connects to port 80 or 443, depending upon the SSL-enabled status of Egenera PAN Manager - i.e., if Egenera PAN Manager is not SSL-enabled (i.e., if the SSL flag above is set to No), then the eG agent connects to Egenera PAN Manager using port 80 by default, and if Egenera PAN Manager is SSL-enabled (i.e., if the SSL flag is set to Yes), then the agent-Egenera PAN Manager communication occurs via port 443 by default. Accordingly, the PAN Manager Webport parameter is set to default by default.

In some environments however, the default ports 80 or 443 might not apply. In such a case, against the PAN Manager Webport parameter, you can specify the exact port at which the Egenera PAN Manager in your environment listens, so that the eG agent communicates with that port for collecting metrics from the Egenera PAN Manager.

Detailed Diagnosis

To make diagnosis more efficient and accurate, the eG Enterprise suite embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option.

The option to selectively enabled/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

  • The eG manager license should allow the detailed diagnosis capability
  • Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.
Measurements made by the test
Measurement Description Measurement Unit Interpretation

Status

Indicates the current state of this pNode in this PAN Domain.

 

If the pNode is powered on in this PAN Domain, then the value of this measure will be reported as Powered on. If the pNode is powered off, then the value of this measure will be reported as Powered off.

The numeric values that correspond to the above-mentioned measure values are as follows:

Measure Value Numeric Value
Powered on 1
Powered off 0

Note:

By default, this measure reports the above-mentioned Measure Values while indicating the current state of a pNode. However, in the graph of this measure, the state will be represented using the corresponding numeric equivalents i.e., 0 or 1.

Clock speed of CPU

Indicates the clock speed of the CPU in this pNode.

GHz

 

Sockets

Indicates the number of sockets available in this pNode.

Number

 

Cores

Indicates the number of CPU cores available in this pNode.

Number

 

RAM

Indicates the size of RAM available in this pNode.

GB

 

Cache memory

Indicates the amount of memory that is allocated for cache in this pNode.

MB

 

NICs

Indicates the number of virtual Network Interface Cards (NIC) available in this pNode.

Number

vNIC is the Virtual Network Interface Card i.e., in this case, a PAN Manager Ethernet interface you create on a pServer. A vNIC interface functions just like a physical NIC, and is the means by which a pServer connects to an Ethernet network.

HBAs

Indicates the number of virtual Host Bus Adapters (HBA) that are currently available in this pNode.

Number

The Virtual Host Bus Adapter (vHBA) is a PAN Manager SAN interface you create on a pServer. A vHBA interface functions like a physical HBA, and is the means by which a pServer connects to a SAN environment.

HW event log utilization

Indicates the percentage of eventlog that is currently utilized in this pNode.

Percent

 

Is pNode in local pool?

Indicates whether/not this pNode is in the local pool.

 

A local pool is a set of processing resources used by a specific LPAN and from which pNodes can be assigned to pServers running in that LPAN.

The pNode in a local pool cannot be assigned to pServers running in other LPANs. Administrators can link a local pool to a Global Pool, so the PAN Manager will attempt to allocate a pNode from the global pool if it cannot obtain one from the local pool.

This measure reports the value Yes, if this pNode is in the local pool and the value No if this pNode is not in the local pool.

The numeric values that correspond to the above-mentioned measure values are as follows:

Measure Value Numeric Value
Yes 1
No 0

Note:

By default, this measure reports the above-mentioned Measure Values while indicating the pool to which a pNode belongs. However, in the graph of this measure, the same will be represented using the corresponding numeric equivalents i.e., 0 or 1.

Is pNode in global pool?

 

Indicates whether/not this pNode is in the global pool.

 

Blocks/Sec

 

A global pool is a pNode Pool that is used by the whole PAN, from which pNodes are made available to pServers running in the PAN. A global pool spans LPANs i.e., the pNodes in a global pool can be made available to pServers running in any LPAN.

This measure reports a value Yes, if this pNode is in the global pool and a value No if this pNode is not in the global pool.

The numeric values that correspond to the above-mentioned measure values are as follows:

Measure Value Numeric Value
Yes 1
No 0

Note:

By default, this measure reports the above-mentioned Measure Values while indicating the pool to which a pNode belongs. However, in the graph of this measure, the same will be represented using the corresponding numeric equivalents i.e., 0 or 1.
