Nagios alternative

Nagios is open source.
Nagios isn’t free.

Fact. Nagios isn’t always the best monitoring tool... Now we don’t want to upset the open source community, nor do we want to stop anyone from ever using Nagios; we just want to present an alternative argument - and a great Nagios alternative. Server Density. Step by step.

How much is your time worth? $40/h

How many servers do you need to monitor? 10 Nagios will suffer over 100 servers and become almost unmanageable with 200+. Besides cost, with these numbers you should worry about scaling.

  • $0 Assuming AWS x1 m3.medium at $0.070/h for monitoring fewer than 50 servers. Above that, x1 m3.xlarge at $0.280/h. Increases to x4 when redundancy is checked (x2 instances across x2 regions).
  • $0 Assuming 0 hours for the initial Nagios configuration.
  • $0 Assuming 0 hours to install and configure the Nagios agent on the first server. Then 5 mins for each additional server when copying over the same config.
  • $0 Assuming 0 hours to setup email and SMS alerts, ignoring the cost of additional service(s) and per message costs. Also excludes iPhone/Android mobile apps.
  • $0 Assuming 0 hours to craft basic graphing. You'll need separate tools like Cacti or Graphite and more than two days for fine tuning and complex plots.
  • $0 Assuming 0 hours for basic security hardening. Does not include ongoing assessments and regular security updates.
  • $0 Assuming 0 hours to equip your infrastructure with automated failover and geographical redundancy across 2 data centres. Not including 24/7 on-call maintenance (that SD offers). This figure also impacts on hardware costs.
  • $0 You'll need an external tool for monitoring your Nagios servers on 2 data centers with failover for each ($45/month on Server Density).You'll need an external tool for monitoring your single Nagios server ($10/month on Server Density).
  • $0 Assuming 0 hours of maintenance every year, to keep it simple e.g. Nagios releases, OS patches, VM decomissioning, hardware refreshes.
  • $0 Assuming 0 hours every year for incidents on your monitoring servers. Dealing with hardware or VM failure, network outages, emergency upgrades.
  • $0 3rd party service needed. A '50 checks' Pingdom account ~ $250/year (as of Nov 2014)

Accessing your data

Alternative API

It’s not easy to get your data out of Nagios, but it is with Server Density,
anything you can do with our interface you can also do with our API.

# e.g. create devices and automate provisioning
> curl -v --data name=Llama

# e.g. easily get all open alerts
> curl -X GET

Alternative Interface

There’s more to this story than money. Few work with the Nagios interface alone, preferring instead to spend time plugging metrics into Cacti or Graphite. Server Density's interface is clear and intuitive out of the box.

Take a look at our monitoring graphs.

Monitoring workflow, reworked

Graphing, dashboards, correlation

Comparing and correlating metrics on a real time dashboard is key to being proactive. With our HTTP API and using our tools like monitoring dashboards and hover sync, you can spot issues before they cause downtime. All part of the product.

Configuring Nagios Alerts

Reacting to alerts is crucial part of any monitoring workflow. They need to be flexible and reliable to alert you in the right way, at the right time, everytime. Nagios defaults to email only, requiring 3rd party services to set up SMS alerts or Android and iPhone Push notifications.

We do it all.

Nagios Plugins. Without Nagios.

Nagios plugins wrapper

Nagios is famous for its plugins and so are we. Not only have we launched our own plugin library, but we've also created a Nagios wrapper, so your favourite Nagios plugins also work with us.

This also means no more writing plugins in C.

Nagios Alternative - ScalingScaling

Most growing companies need a monitoring solution that scales up and down seamlessly.

Nagios assumes a static infrastructure

What's a Nagios cluster? It doesn't exist. With elastic cloud environments, assuming a static infrastructure is dangerous because servers come online frequently - sometimes hourly.

Aspirations of over 100 servers?

100 seems to be the Nagios number. It scales reluctantly until you reach 100 servers, then in most cases you'll have to rethink and rebuild your solution when you grow to that level.

Is security a concern?

If you’re worried about security, then know that we take security very seriously.
