PAN OPServer Details

The Egenera PAN Manager application runs on a PAN OPServer that is running on a 64-bit Red Hat. The PAN Manager application running on the PAN OPServers manages the physical and virtual resources of the domain(s) in the PAN. The Egenera PAN Manager is designed to run redundantly on two PAN OPServers, in a master/slave role. The master PAN OPServer performs all management functions while the slave has the ability to assume the master responsibilities in case of failure in the master PAN OPServer.

In a non-redundant setup therefore, sudden or intermittent breaks in the availability of the PAN OPServer can bring the PAN Manager application to a standstill, taking down all the mission-critical servers and applications that operate on it. By periodically checking the availability of the PAN OPServer and promptly reporting the non-availability of that server, administrators can take timely measures to restore the PAN OPServer to normalcy and thus greatly minimize PAN Manager downtime. 

This test helps administrators achieve this end. The test reports whether the PAN OPServer is currently available or not and also indicates whether the server being monitored is the master/slave in a redundant setup.

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 PAN OPServer 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 status of this PAN OPServer.

 

This measure reports the value Available if the PAN OPServer is currently available and the value Not Available if otherwise.

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

Measure Value Numeric Value
Not Available 0
Available 1

Note:

By default, this measure reports the above-mentioned Measure Values while indicating the status of this PAN OPServer. However, in the graph of this measure, the status will be represented using the corresponding numeric equivalents of the Measure Values.

The detailed diagnosis capability of this measure, if enabled, lists out the global IP address, the name of the Network Interface through which the global IP is assigned, the IP address of the master PAN OPServer, the name of the master PAN OPServer, the IP adress of the slave PAN OPServer, the name of the slave PAN OPServer, the version of the PAN OPServer and the role of this PAN OPServer in this Egenera PAN Manager.

Is master role?

Indicates whether this PAN OPServer is the master server in a redundant setup.

 

This measure reports a value Yes if this PAN OPServer is the master in a redundant setup and the value No if this PAN OPServer is not the master.

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

Measure Value Numeric Value
No 0
Yes 1

Note:

By default, this measure reports the above-mentioned Measure Values while indicating whether/not this PAN OPServer is the master. However, in the graph of this measure the master/slave status of the server will be represented using the corresponding numeric equivalents of the Measure Values.

 

The detailed diagnosis capability of the Status measure, if enabled, lists out the global IP address, the name of the Network Interface through which the global IP is assigned, the IP address of the master PAN OPServer, the name of the master PAN OPServer, the IP adress of the slave PAN OPServer, the name of the slave PAN OPServer, the version of the PAN OPServer and the role of this PAN OPServer in this Egenera PAN Manager.
