Physical Node Detail Test

Alliance Messaging Hub (AMH) is a modular, financial messaging solution for corporate networks. It allows extensive throughput and sophisticated data management through the use of latest technology to manage messages and files. The AMH system is composed of a number of physical nodes which are nothing but servers running AMH software. Given that each physical node is the building block of entire system and provides all compute power, it is important that each node works optimally.

This test monitor the physical nodes, and collects key statistics about node performance its state, heartbeat, etc. These metric provide administrators with valuable insights about the health of the node and any potential issues which can be handled before it affects the entire system.

Target of the test : A Swift AMH Cluster instance

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each physical node in the cluster being monitored.

Configurable parameters for the test

Parameter

Description

Test period

How often should the test be executed.

Host

The host for which the test is to be configured.

Port

The port at which the specified host listens.

Detailed Diagnosis

To make diagnosis more efficient and accurate, the eG Enterprise 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 enable/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.
Measures made by the test

Measurement

Description

Measurement Unit

Interpretation

Is this node part of the cluster?

Indicates if the node is part of cluster or standalone.

 

The numeric values that correspond to these measure values are as follows:

Measure Value Numeric Value
Yes 10
No 0

Note:

By default, this measure reports the Measure Values listed in the table above to indicate the Is this node part of the cluster?. In the graph of this measure however, the same is indicated using the numeric equivalents only.

Physical node state

Indicates the current state of physical node.

 

The numeric values that correspond to these measure values are as follows:

Measure Value Numeric Value
Running 20
Degraded 10

Stopped

 5

Not running

 0

Note:

By default, this measure reports the Measure Values listed in the table above to indicate the Physical node state. In the graph of this measure however, the same is indicated using the numeric equivalents only.

Time since last heartbeat

Indicates the time since the last heartbeat check was received by physical node.

Minutes

If it has been very long and over the threshold value, it needs to be investigated.

Logical nodes currently on physical node

Indicates the number of logical nodes running on current physical node.

Number

A large number of logical nodes on one physical node may not be able to provide good performance and can increase the chances of node crashing.

Logical nodes recently moved into this physical node

Indicates the number of logical nodes that were moved to current physical node since last measurement.

Number

While moving the logical nodes to current physical node, make sure to consider the load on the physical node.

Logical nodes recently moved out of this physical node

Indicates the number of logical nodes that were moved out of current physical node since last measurement.

Number

Moving the logical nodes out could be the right thing to ease the load on the node.

Is AMH running

Indicates if AMH is running on the current node.

 

The numeric values that correspond to these measure values are as follows:

Measure Value Numeric Value
Yes 10
No 0

Note:

By default, this measure reports the Measure Values listed in the table above to indicate the Is AMH running. In the graph of this measure however, the same is indicated using the numeric equivalents only.
