Prerequisites Copied
Opsview Cloud
For Opsview Cloud customers, please contact ITRS Support for assistance with these steps, as they require Orchestrator access.
Ruby Copied
The ruby Cloudscripts gem is used with this Opspack and should be installed as the opsview user. Ruby and rubygems should be available on your system and already use the command:
gem install CloudyScripts
On Ubuntu 10 Lucid, you should also install SSL support for Ruby:
apt-get install libopenssl-ruby
Security Copied
An RSA key must be generated and saved to enable encryption of your AWS details. Use the command: mkdir /etc/cloutomate/ ssh-keygen -f /etc/cloutomate/cloutomate.pem and enter a blank passphrase, to create this file.
Note: sudo may be required in order to execute these commands, although the files cloutomate.pem and aws_credentials.cfg must be owned by opsview user; otherwise the values cannot be read by the plugin.
Amazon Copied
You will need access to the Amazon Web Services account you wish to monitor, along with a valid Access Key and its Secret Key. See Amazon’s Documentation for information about using keys for security.
Configuration Copied
Creating a credentials file Copied
First, use the encrypt_aws_credentials.rb script to generate your credentials file:
ruby /opt/opsview/monitoringscripts/etc/plugins/cloud-aws/encrypt_aws_credentials.rb -A (your Amazon access key ID) -S (your Amazon secret key) -f /opt/opsview/monitoringscripts/etc/plugins/cloud-aws/aws_credentials.cfg
You can find your Access Key(s) by logging into the AWS site and accessing “Security Credentials” from your account’s drop-down. If you don’t know the Secret Key, you may need to create a new key.The created file must not be distributed down to slaves.
Your Amazon host Copied
You will need to know the Amazon server to enter as the Primary Hostname. This will be shown under “Public DNS” in the instance information on Amazon’s Management Console.
Variables Copied
AWS_CLOUDWATCH_CREDENTIALS must have arg2 set to the Amazon Instance ID - also available from the AWS Management Console.
Example Installation Copied
Environment:
CLI:
sudo mkdir /etc/cloutomate
sudo ssh-keygen -f /etc/cloutomate/cloutomate.pem

sudo chown -R opsview:opsview /etc/cloutomate
sudo chown opsview:opsview /opt/opsview/monitoringscripts/etc/plugins/cloud-aws/aws_credentials.cfg
