3 CHAPTER 1 Setting Up the Tetration Cluster Cisco Tetration Cloud, page 1 Preparing for the Tetration Cluster Setup, page 2 Deploying the Orchestrator, page 4 Setting Up the User Interface, page 5 Cisco Tetration Cloud The Tetration Cluster Cloud deployment option allows you to run Cisco Tetration Analytics software, which runs in a public cloud instance such as Amazon Web Services (AWS). You are responsible for purchasing the required AWS instances directly from AWS to run Cisco Tetration Analytics software. This deployment option is suitable when you need to collect and analyze telemetry from fewer than 1000 servers (virtual machine or bare metal). The monitored servers can be in AWS and an on-premises data center. If telemetry needs to be collected from the on-premises servers, then AWS Direct Connect or a VPN is required to connect to the Cisco Tetration Cloud platform. Note This release of Cisco Tetration Analytics Software supports cloud deployment only in AWS. The following table lists the number of instances, TBs, and addresses required for using Tetration. AWS Instance Type Required t2.medium 6 instances m4.large 15 instances m4.2xlarge 2 instances m4.xlarge 3 instances r4.large 13 instances 1

4 Preparing for the Tetration Cluster Setup Setting Up the Tetration Cluster AWS Instance Type r4.2xlarge r4.xlarge m4.4xlarge Amazon EBS: General-purpose SSD (gp2) Amazon EIP Required 23 instances 4 instances 8 instances 65 TB 50 addresses Preparing for the Tetration Cluster Setup Use a client device to complete the following steps before starting the Tetration Cluster setup. Be sure that the client device is setup with the following: The client device must be setup with the following: Microsoft Windows or Linux operating system Python software version 2.7 or later Access to the Internet Step 1 Create a new AWS account by going to a) Enter your userid, phone number, and password. b) Wait for a pin (typically a four-digit number). c) Receive a call from Amazon and enter the pin on the telephone. After you successfully enter the pin, Amazon announces that you have been authenticated. Online, you will be asked for a user plan. d) Select the appropriate user plan based on the amount of support that you must have, and click Continue. Step 2 On the AWS page that opens, verify that the AWS limits are set as needed by doing the following: a) On the AWS page, select the Services tab at the top of the page, and then select Compute > EC2. b) On the Resources page navigation pane, select Instances > Instances, and then select EC2 Dashboard > Limits. c) In the Support Center page that opens, do the following for each of the AWS limits that you must change (see the following table for the recommended limits): AWS Instance Type Recommended Limit Values t2.medium m4.large m4.2xlarge m4.xlarge 10 instances 20 instances 5 instances 5 instances 2

5 Setting Up the Tetration Cluster Preparing for the Tetration Cluster Setup AWS Instance Type r4.large r4.2xlarge r4.xlarge m4.4xlarge Amazon EBS: General-purpose SSD (gp2) Amazon EIP Recommended Limit Values 15 instances 25 instances 5 instances 10 instances 70 TB 50 addresses 1 Select your Region. 2 Select the Primary Instance Type. 3 Select the Limit type as Instance Limit. 4 Enter the New limit value. 5 If you need to change another limit, click the Add another request button and repeat steps i through iv. 6 In the Use Case Description text box, type the reason for these limit changes. 7 Click the Submit button at the bottom of the page. AWS lists a summary of your changes. Step 3 Step 4 Check for an alert from Tetration for a password reset and other platform related events. Note See the account that you indicated when setting up your AWS account (can use Sendgrid or Amazon CES). Create an S3 bucket in the new AWS account to be used for storing CloudFormation templates by doing the following: a) In the AWS page, click the Services tab at the top of the page. b) In the services page, click Storage > S3. c) In the Amazon S3 page, click the Create bucket button at the top of the page. d) In the Create bucket page, do the following: 1 In the Bucket name text box, type the name of the bucket. 2 In the Region box, select the appropriate region. 3 If you have settings to copy into the bucket from another bucket, in the Copy settings from an existing bucket box select the bucket with the settings that you must copy. 4 Click Create. Note Step 5 Provide your Cisco representatives with the following information so that they can install libraries and generate a set of AWS credentials: 3

6 Deploying the Orchestrator Setting Up the Tetration Cluster AWS IAM role API key API secret S3 bucket name What to Do Next After your Cisco representatives create the libraries and generate the AWS credentials, you are ready to run the Orchestrator deployment script. Deploying the Orchestrator Cisco provides a zip archive containing the following files: AwsHelperGuide.md config.yml This is the configuration file used to populate vital CloudFormationparameters. orchestrator.yml.j2 This is the Jinja2 template used to generate the CloudFormation template. tetration_cluster_launcher.py This script launches a Tetration cluster using the config.yml and orchestrator.yml.m2 files. vpc_peering_role.yml This file launches a CloudFormation stack that creates a VPC peering connection IAM role. Step 1 Look at the following values in the config.yml file and verify that they are set correctly: cluster_name The name of the Tetration cluster. This name must match the site name. vpc_cidr external_cidr region availability_zone s3_bucket_name The CIDR-formatted network range of the Tetration cluster VPC (string) CIDR-formatted network ranges to allow ingress to the Tetration UI (list) The AWS region where the Tetration cluster instances will be launched. The AWS availability zone where Tetration cluster instances will be launched. Currently, Tetration can be launched in only one availability zone. The name of the S3 bucket created in the Preparing for the Tetration Cluster Setup section. 4

7 Setting Up the Tetration Cluster Setting Up the User Interface Step 2 Execute the tetration_cluster_launcher.py script by using the tetration_cluster_launcher.py -c config.yml_path -t orchestrator.yml.j2_path command. Step 3 Follow the Tetration Setup Wizard using the link provided from running the tetration_cluster_launcher.py script. Note the IP addresses output by this script (output can also be found in the tetration_cluster_launcher.log file) for future use :23:43,111 - main - INFO - ****************************** :23:43,111 - main - INFO :23:43,111 - main - INFO - Cluster Setup URL: :23:43,111 - main - INFO :23:43,111 - main - INFO - ****************************** :23:43,111 - main - INFO - Internal Network: / :23:43,111 - main - INFO - External Network: / :23:43,111 - main - INFO - External Gateway: :23:43,111 - main - INFO - DNS Resolver: :23:43,111 - main - INFO - NTP Servers 0.amazon.pool.nrg 1.amazon.pool.ntp.org 2.amazon.pool.ntp.org 3.amazon.pool.ntp.org :23:43,111 - main - INFO :23:43,111 - main - INFO - ****************************** What to Do Next Set up the UI using the output from the Orchestrator deployment output.
