Likelihood to Recommend

Ansible

I would recommend Ansible to anyone, but I recognize it might not fit everyone's needs. I'm not as familiar with Chef, Puppet, or Salt, but they each have their strengths. For us, we needed to be able to manage a new server the moment it was created, so agent-based solutions were out. For our use, Ansible does everything we've asked it to.

Nagios

Nagios is simply a very configurable and rock solid monitoring engine. For these reasons I would recommend it to any IT professional in any medium to large organization where creating custom checks and programming ones custom needs into the configuration is practical. I would be more hesitant to recommend it as a first monitoring solution for a small business which is usually accompanied by a less experienced and/or more time constrained admin.

Pros

  • Agentless. For our implementation, this is the single biggest factor. If we have to touch the machine and install an agent before we can start managing it, that's already too much effort and slows us down.
  • Re-entrant. This is not unique to Ansible, but certainly a huge improvement over custom scripts and such. Because it's such a huge effort to make scripts re-entrant, most of our scripts did not allow an elegant way to recover on failure. Manually cleaning up the half-attempt and re-trying is still too cumbersome, and being able to just re-run Ansible is a great improvement!
  • Infrastructure as code. This is new to Ansible, and there are still a few minor bugs with their AWS modules, but it's been a huge help being able to define our infrastructure in an Ansible playbook, commit it to source control, and use one tool for all our DevOps tasks.

  • Up/Down Alerting.
  • Monitoring of supported applications (SQL, Exchange, etc).
  • Upon an alert, Nagios' ability to fire off scripts allows us to either fix problems automatically or gather data about an issue as soon as it happens.

Cons

  • Unlike Chef, Ansible employes a Push methodology rather than Pull. We found that this doesn't scale well for us, thus we had to consider using Ansible Tower in order to scale.
  • Ansible's free training and tutorials do no provide as much depth and ease for first time users trying it out for the first time.
  • From the limited experience we have had with Ansible Tower, the UI is not very user friendly. There's a lot of bells and whistles that can prove o be overwhelming at times.

  • If it gets too customized, upgrading becomes very difficult. They've addressed this in recent years with Nagios Core and add-ons, but legacy still has this problem.

We're currently looking to combine a bunch of our network montioring solutions into a single platform. Running multiple unique solutions for monitoring, data collection, compliance reporting etc has become a lot to manage.

The Nagios UI is in need of a complete overhaul. Nice graphics and trendy fonts are easy on the eyes, but the menu system is dated, the lack of built in graphing support is confusing, and the learning curve for a new user is too steep.

Performance

Ansible7.5
Based on 2 answers
Out of the box, Ansible can be slow over a bad connection, as it's establishing an SSH connection to the target server for each little task. There are some adjustments you can make to the defaults that greatly improve performance. And if you run Ansible on the same network as the target (i.e. by using a jump box or Jenkins server), then it can be crazy fast. I'd give it a 10 for speed except that it does require these adjustments first.

Alternatives Considered

Ansible is a great product, which we really love as it is compatible running along side and with other DevOps tool. The integration features allows other teams to participate in our shared objective. Ansible is easy to use as many programmers are familiar with Python and RHEL. We selected Ansible because its easy barrier to entry and pricing model for new users with not many nodes to manage. We will continue to develop and on-board teams and monitor the scaling abilities of Ansible.

We selected Nagios because of economic constraints with a tool completely free, nor to have a stable product that has reached a stable state since years. . We wanted an extensible product based on number of plugins and a product that can grab datas from many infrastructure products on the market

Return on Investment

  • Ansible has definitely helped our security team keep our servers up to date on the latest vulnerabilities through their continuous team of patch deployments.
  • The time to market for our code deployments have sped up 3 fold at least and is expected to continue improving as more teams are comfortable with DevOps framework.
  • Ansible is open source and free, which is great. But for an enterprise deployment, we had to budget for extra nodes as Tower only comes with licenses for 10.

  • Affordable tool available for free to cover infrastructure supervision scope
  • Dynamic alerting to become proactive for user support, before incident management process is fed
  • Scalable tools that helps to progressively have a service dependencies approach
