Overview Spectrum Control provides metric data in CSV format for which the Mediation Pack will

use to formulate content into Predictive Insights. IBM Operations Analytics Predictive

Insights Mediation Pack for Spectrum Control provides a pre-built model for data

ingestion. Predictive Insights creates a performance model that it uses to detect or

forecast behavior outside the modeled range, including generating an alarm when an

anomalous behavior occurs. Doing so enables organizations to pro-actively avoid system

and solution outages before users are impacted.

Spectrum Control Solution

Overview


Spectrum Control Data and Metrics

Spectrum Control mediation pack provides metric data in CSV format for which

the Mediation Pack will use to formulate content into Predictive Insights.

The Spectrum Control mediation pack provides scripts that retrieve the metric

from the Spectrum control server every 15 minutes.

Data is then sent to a python script on the predictive insight server which then

formats the metrics into 5 minute interval CSV files.

Mediation Pack Contents Continued

/bin directory contents

on_spctrum_control_server directory:

run.bat (Use if Spectrum Control is on Windows), run_AIX.sh (Use if Spectrum Control

is on AIX), run_linux.sh (Use if Spectrum Control is on Linux):

The run.bat or run.sh scripts reside on the spectrum control server. These scripts execute the

exportPerformanceData script of Spectrum Control to collect the data from the Spectrum

Control for the storage systems names that are given in the allStorageSystems.txt file.

After successful collection, these scripts transfer the raw files (performance reports) from the

Spectrum control server to the Predictive Insights server.

After the transfer is complete, the script deletes the raw files from the Spectrum Control

directory. Then the run.bat or run.sh executes the Python script on the Predictive Insights

server remotely to produce files for ingestion in Predictive Insights.



/bin directory contents

on_pi_server directory:

spectrumControl.sh (Bash script to be placed on PI server)

This script resides on the Predictive Insights server in the directory of the user’s choice. This

script executes the Python script from the same directory. The Python script takes the files

that have arrived from the Spectrum Control server and converts them into five-minute csv

files with the metrics that are configured in the spectrumControl_config.json file.

spectrumControl_generator.py (Python script to be placed on PI server)

This Python resides on the PI server in the same directory as the spectrumControl.sh script.

Users should not edit this script.



/pamodel directory contents

Core files used in the Mediation Pack representing the Predictive Insights model consisting of

all attributes and metric definitions.

SpectrumControl_2.pamodel

The SpectrumControl_2.pamodel file is a PI model file which consists of all attributes and

metric definitions. This file consists of all metric group definitions. Import this file into mediation

tool.

/sample directory contents

Contains a sample CSV file representing the captured data streams that can be used to try the

Mediation Pack output in the Operations Analytics Predictive Insights product. There are two

five-minute interval files per metric group.


Configuring the Mediation Pack

The following slides describe the steps that are necessary to add the Mediation

Pack to your Operations Analytics Predictive Insights system.

The first major steps are to setup and configure the scripts that will be executing

on the Spectrum Control Server and the Predictive Insights Server.

The second major step is to Configure the Data Model.

The last step is to create the topic.


Configuring the Mediation PackOverview of the Scripts Execution on Spectrum Control and Predictive

Insights Servers

Every 15 minutes, the run.bat or run.sh script will execute the exportPerformanceData.bat

or .sh script which comes out of the box with Spectrum Control. The run.bat or run.sh script

will form a command to execute by reading “mediationProps.txt”, “allStorageSystems.txt”.

After execution, the metric files will be stored on the spectrum control server at the location

given by user in the “mediationProps.txt”.

These files will be then transferred to the Predictive Insights server as per the path given by

the user, followed by deletion of the files from the Spectrum Control server. After a

successful transfer, a Python script on the Predictive Insights server will be executed

remotely by run.bat or run.sh to produce 5-minute interval files on the PI server.

The Python script will take the transferred files from the Spectrum Control server as input

files and produce 5-minute files with selected metrics, in the location per the user’s

preference, given in “spectrumControl_props.txt” file, which resides on the PI server.


Configuring the Mediation PackSetting up the scripts on the Spectrum Control Server

1. Copy the files run.sh or run.bat, mediationProps.txt, allStorageSystems.txt on the Spectrum Control

server in a new directory from the relevant OS directories of the mediation pack (Upload the plink.exe

and pscp.exe if Spectrum Control is running on Windows operating system).

2. Edit the Field descriptions for properties in the “mediationProps.txt” file as follows:

UserName: - The Spectrum Control UserName, given for extraction of the data

Password: - Spectrum Control Password

Server: - Spectrum Control Server IP/HostName

Port: - Spectrum Control Port Number

Destination: - Location where Spectrum Control files dump are to be stored on the Spectrum Control server. The user must

have read/write permissions to this directory as every 15 minutes, new files are going to be placed along with the deletion

of the old files.

Script: - The location of the exportPerformanceData script on the Windows/AIX Spectrum Control server.

resTypes: - The metric groups that user wants to be extracted for StorageSystems. (For the StorageSystems given in

allStorageSystems.txt file) (e.g. Nodes, Ports, Volumes, StorageSystem, HostConnections, IOGroups etc.)

PI_User: - Username of the Predictive Insights server. (Usually scadmin)

PI_Password: - Password of the Predictive Insights User.

PI_FileLocation: - The location where the transferred files from spectrum control server the user wants to hold every 15

minutes (As spectrum control server, this folder will be temporary location to hold files. Every 15 minutes, Python script will

read files from here, and delete after processing).

Exec_Command: - The path where the spectrumControl.sh executable is placed the PI server


Configuring the Mediation PackSetting up the scripts on the Spectrum Control Server (continued)

3. Optionally edit the allStorageSystems.txt file which the user can define a sub list of desired

storage systems to retrieve metrics from user’s environment. If the user wants to retrieve all

storage systems metrics, leave this file blank.

4. Make sure that the ‘plink.exe’ and ‘pscp.exe’ are copied to the Spectrum Control server if

Spectrum Control is running on a windows operating system.

5. Make sure that the run.bat or run.sh script is copied to the Spectrum Control server. The

user should not edit this file.

Notes:

All the above mentioned files should reside in the same directory on the Spectrum Control

server.

It is recommended that the user edits the files on native operating system. E.g. Properties file

for Spectrum Control Linux server should be edited on Linux OS. In case the file to be placed

on UNIX server is edited on Windows server, use the dos2unix command to make the file Unix

compatible.


Configuring the Mediation PackSetting up the scripts on the Predictive Insights Server

1. Download the anaconda package on the Predictive Insights server.

• Download the installer in a directory of your choice (login using scadmin):

$ wget https://repo.continuum.io/archive/Anaconda3-5.0.1-Linux-x86_64.sh

• Make the .sh file executable if it is not already.

• Execute the downloaded .sh file and follow the prompt, it will ask usual questions –

agreement etc.

• When prompted, keep the default installation location or change per user’s preference.

Make a note of installation location.

• When asked, “Do you wish the installer to prepend the Anaconda3 install location to

PATH in your “/home/scadmin/.bashrc?”, Say No.

2. Copy the spectrumControl_config.json, spectrumControl_props.txt, from the

mediation pack /config/on_pi_server directory and the spectrumControl_generator.py,

spectrumControl.sh from the mediation pack /bin/on_pi_server directory to the

Predictive Insights server to a new directory of the user’s choice.


Configuring the Mediation PackSetting up the scripts on the Predictive Insights Server (continued)

3. Edit the spectrumControl_props.txt file

inputFilesPath: - Path where the files are coming from Spectrum Control Server. This path is same as the

‘PI_FileLocation’ field in ‘mediationProps.txt’ file on the Spectrum Control server.

outputFilesPath: - Path where user wants to store five minute files. This will be the directory for Predictive

Insights training (make sure path given here is valid and exists).

4. Edit the spectrumControl.sh script file and on line 2, enter the path of

~/anaconda3/bin directory which is been created after installing anaconda package. An

example is shown below:

ANACONDA3_BIN_DIR=/home/scadmin/anaconda3/bin

5. Make the spectrumControl.sh script executable using chmod.

6. After configuring the pack on the Predictive Insights server, make a note of the path

pointing to the spectrumControl.sh script. Enter this path in Exec_Command variable

(the last line) in the mediationProps.txt file.

Example:

Exec_Command=/home/scadmin/SpectrumExt/spectrum_control/spectrumControl.sh


Configuring the Mediation PackSetting up SSH Key for Spectrum Control on Unix

SSH keys should be set up between Spectrum Control server and Predictive Insights server before

executing run.sh/run.bat script. This is required to automate the file transfer.

1. Create the RSA Key Pair on Spectrum Control server using the following: $ ssh-keygen

2. Type ‘Enter’ when prompted for storing the keys and passphrase (leave empty).

3. Display the pub key using the following command:

$ cat ~/.ssh/id_rsa.pub

This will output something like below.

ssh-rsa

4. Copy the entire contents and go to your PI server’s console. Create a directory called ssh in the home

directory as shown below.

User needs to execute the following commands as root user on the Predictive Insights server.

$ mkdir -p ~/.ssh

5. Now, append your client system’s public key which you generated in the previous step as shown below:

echo {Your_public_key_contents_here} >> ~/.ssh/authorized_keys

6. Restart ssh service on the Predictive Insights Server.


Configuring the Mediation PackTransferring files if Spectrum Control is running on Windows

If Spectrum control is on Windows, there are different ways to do automate a transfer.

For the current version of the pack, after configuration of mediation pack contents on the

Spectrum Control server as well as on the Predictive Insights server:

For the first time, the user should save the RSA token. This will allow the script to authenticate

from next time without a prompt.

1. Execute run.bat script from the command line.

2. For the first execution, the prompt will ask user if the keys should be stored locally in a cache

for future reference.

3. Enter a yes response when prompted.

4. Execute the script again. This time the script should completely execute without any

prompts.


Configuring the Mediation Pack

Scheduling the run script via a Cron Job using cron-tab

1. Open a Terminal Window (Command Line).

2. Give the shell script the correct permission. For example, if the script is called

“run.sh”, set permission as follows: chmod 755 run.sh

3. Add new cron job to crontab using the following command:

crontab –e

This opens the vi editor for you if your default editor is vi. You can set a different editor using

the following: export EDITOR=emacs

Create the cron command using the following syntax:

*/15 * * * * /path_to_run.sh/run.sh

This will execute run.sh on Spectrum Control server every 15 minutes.
