Power-Shell Script to check Maximo/Websphere Ports

Power-shell script to check port connection of Maximo servers and export result to .csv file.

Overview:

• Maximo server use a variety of ports dedicated to specific function/application.

• Ports at UI level (9080, 9081 etc). or RMI port are obvious and easy to validate. But other ports at NodeAgent, Deployment manager level and few JVM ports that are crucial for health of the application not often checked.

• It is best practice to periodically check connection of these ports. Escpecially during any server upgrade/patching.

• This article shares a method to automate this via powershell script.

• We use 'tnc 'ServerName' -p '<portNumber>' as base code, which is recursively called  against a list of Ports and Servers. The Result is then printed to a .csv file a report.

Steps:

Retrieve the Port details from Webspshere for each JVM, Node Agent.

Create a powershell script in any text editor as explained below and save as .ps1 file.(We can execute this manually , or schedule a windows Job.)

• Declare the output file with timestamp:

$today=Get-Date -Format "dd-MM-yyyy-HHmm";

$exportFilePath="C:\Maximo\HealthCheck\Reports\PROD_Server_Ports_Health"+$today+".csv";

• Declare each server names to a variable.

$appSvr01="PRODMAXIMOAP01.orgxx.com"; 
$appSvr02="PRODMAXIMOAP01.orgxx.com"
$adminServer="PRODMAXIMOADM01.orgxx.com"

• Declare list of ports of different type (JVM, Node Agent etc.)

 $JVMPorts="9080","9081","9082","9083";      

 $nodeAgentPorts="2810","9902","9203","9204","7273","8879","9630","7063","11005","11006"; 

$nodeAdminPorts="2810","9902","9203","9204","7273","8880","9630","7063","11007","11008"; 

$dmgrPorts="7277","9809","9632","8879","9100","9402","9060","9043","9352","7060","9420","11005","11006";

• Declare List of Port Types in Seqence

$portTypeList = "JVM","JVM","NodeAgent","NodeAgent","NodeAdmin","Dmgr";

• Now, declare List of all Servers and ports. That is combination of avove variables in correct sequence.

$serverList=$appSvr01,$appSvr02,$appSvr01,$appSvr02,$adminServer,$adminServer

$portListAll = $JVMPorts,$JVMPorts,$nodeAgentPorts,$nodeAgentPorts,$nodeAdminPorts,$dmgrPorts;

The sequence of values in each list should match the value of others. So that, when we itrate through these list, it matches with correct server and port.

Server	Port Type	Port List
AP01	JVM	"9080","9081","9082","9083"
AP01	JVM	"9080","9081","9082","9083"
AP01	NodeAgent	"2810","9902","9203",..."11006"
AP01	NodeAgent	"2810","9902","9203",..."11006"
ADM01	NodeManager	"2810","9902","9203",..."11008"
ADM01	Dmgr	"7277","9809","9632",..."11006"

• Finally, iterate through the list of servers , for each server, test the list of ports and write the result.

Result:

The output of the script will generate .csv file with details as shown below.

Source Code:

$today=Get-Date -Format "dd-MM-yyyy-HHmm";

$exportFilePath="C:\Maximo\HealthCheck\Reports\PROD_Server_Ports_Health"+$today+".csv";

$appSvr01="PRODMAXIMOAP01.orgxx.com"; 

$appSvr02="PRODMAXIMOAP01.orgxx.com"

$adminServer="PRODMAXIMOADM01.orgxx.com"

$nodeAgentPorts="2810","9902","9203","9204","7273","8879","9630","7063","11005","11006";

$nodeAdminPorts="2810","9902","9203","9204","7273","8880","9630","7063","11007","11008"; 

$dmgrPorts="7277","9809","9632","8879","9100","9402","9060","9043","9352","7060","9420","11005","11006";

#Declare combined PortList and ServerList in correct sequence.

#Such that, it matches relevant Port to Server as below

#AP01,AP02,AP01,AP02,ADM01,ADM01

#JVM,JVM,nAgnt,nAgnt,nAdmin,Dmgr

$portTypeList = "JVM","JVM","NodeAgent","NodeAgent","NodeAdmin","Dmgr";
