Agile DevOps - People and Process then Automation!!!

Use Cloud and DevOps to build infrastructure by rapid agile iterative development using collaborative open source tools:
-Terraform or Cloud Formation for easy orchestration.
-chef cookbooks, puppet modules or ansible playbooks to build servers.
-Test Kitchen to deploy and test them.
-Packer for build server images or containers.
-EC2Dream a graphic user interface that provides a 'single pane of glass' to do agile devops primarily on cloud servers.
-Amazon AWS, Azure, Google Compute Engine, IBM, Openstack, Local and Hosted servers.

Monitoring EC2 Instances


EC2Dream will create graphs based on Amazon CloudWatch. Amazon has a monitoring facility that can easily be switch on and off without any configuration on your server The service costs 1.5 cents per hour per EC2 instance (of any size) which comes out to $10.95 per month for an instance running 24x7.

Monitis and similar fee-based monitoring services.

Munin open source monitoring.

Nagios open source monitoring. A popular alerting system where you can monitor things like diskspace and set thresholds. An agent must be installed on the server and a Nagios server run.
Cacti is a popular open-source network monitoring tool. In Amazon EC2 there are pre-built images so it is easy to run.
Sensu is an open source monitoring framework that looks very promised for cloud usage. It is written in Ruby and is much less complex than Nagios and able to handle to more dynamic nature of servers in the Cloud.

Hello,

I followed the steps in the guide, and everything seemed to work, I setted up snmp in one of my ec2 instance, opened the 161 udp for the internal ip of the cactis instance, that i created from the AMI you suggested, and it pulled some information allright, the server name, ando some other stuff, but none of the graphics it's getting any data, but the one that show the number of logged users, but all the others (memory usage, processor, etc) are not working.

Do you have any hunt on what coukld possibly go wrong ?

Thanks in advance.

Orlando.
