Nagios Core

Nagios monitoring is well suited for any mission critical application that requires per/second (or minute) monitoring. This would probably include even a shuttle launch. As Nagios was built around Linux, most (85%) plugins are Linux based, therefore its more suitable for a Linux environment.
As Nagios (and dependent components) requires complex configurations & compilations, an experienced Linux engineer would be needed to install all relevant components.
Any company that has hundreds (or thousands) of servers & services to monitor would require a stable monitoring solution like Nagios. I have seen Nagios used in extremely mediocre ways, but the core power lies when its fully configured with all remaining open-source components (i.e. MySQL, Grafana, NRDP etc). Nagios in the hands of an experienced Linux engineer can transform the organizations monitoring by taking preventative measures before a disaster strikes.

SQL Sentry

It has great out-of-the-box features that make it easy to install and get it up and running right away. However, fine tuning and customization of the solution, like setting up custom alerts and notifications, needs to be someones dedicated responsibility. Because of this, we don't necessarily have the time allocated to become true subject matter experts on the tool. What we get out of the box is usually going to be the norm.

Pros

Nagios Core

  • Monitoring of services is one of the biggest benefits for our company. Being able to respond in a timely fashion keeps business smooth.
  • Hardware and device monitoring are easy to set up with proper parameters.
  • Notification to key staff to be able to respond quickly makes issues go away faster.
Eric Krueger | TrustRadius Reviewer

SQL Sentry

  • Alerting is very flexible and configurable to our needs
  • Linking alerting into third party alerting tools via PowerShell was easy
  • Collecting and rolling up SQL statements make it much easier to troubleshoot performance problems
  • Drilling into PLE and what’s happening when it drops out
  • Ease of drilling into time-frame to figure out what was the issue at that time
  • Being able to query the SentryOne database for management reports is awesome (Deadlocks and Blocking)

Cons

Nagios Core

  • Nagios could use core improvements in HA, though, Nagios itself recommends monitoring itself with just another Nagios installation, which has worked fine for us. Given its stability, and this work-around, a minor need.
  • Nagios could also use improvements, feature wise, to the web gui. There is a lot in Nagios XI which I felt were almost excluded intentionally from the core project. Given the core functionality, a minor need. We have moved admin facing alerts to appear as though they originate from a different service to make interacting with alerts more practical.

SQL Sentry

  • The presentation of SQL server waits needs work. A large value on a throw away wait like cxpacket will change the scale such that an important wait like sos_schedular _yield is not readable. I have been told this is being addressed in the next release.
  • Installation of the client requires sysadmin access on the repository server for the initial install. Once the install is complete sysadmin can be removed.
  • There is a web interface but this does not have much of the functionality yet.
  • I have not found a way to view page splits over time.

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.

This tool is invaluable within our organization. With the recent financial impacts to businesses across the globe related to Covid-19, we were asked if we could reduce licenses to cut costs. When we pointed out the business value that the tool brings and the risks that would be taken by not having the tool, the decision was clear. We looked elsewhere to makes cuts.

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.

As a general rule, out of the box use of the product is very easy. With little to no experience in the platform, we were up and running with it inside of 3 days. New developers and DBAs in the organization can get a grip on how to use monitoring features inside of half an hour.

The system is working perfectly in capturing data, but we do experience issues with SQL Timeout when viewing results in the remote clients. This may be due to the fact that our monitoring service is consuming most of the CPU, and it is the same server that is hosting the SQL Repository. We could probably fix the issue by separating the SQL instance from the monitoring service.

In most cases the pages load very quickly. In our particular case, we need to do some movement of services to separate our monitoring service to separate infrastructure from the repository. When we first started with SQL Sentry on 5 licenses, we did not have any issues. Since we have now grown that to 25, we are experiencing some challenges. We do not believe this to be a tool problem

I haven't had to use support very often, but when I have, it has been effective in helping to accomplish our goals. Since Nagios has been very popular for a long time, there is also a very large user base from which to learn from and help you get your questions answered.

They usually respond within a few hours and will pull in needed resources without the need for me to escalate the issue. They take the initiative to follow up. They are open to suggestions for future enhancements and actually implement them. They give the impression they want to resolve your issues.

Understand your user base and work out security in advance. Setting up users may have been the hardest part of implementation. After that teaching the UI to IT professionals was rather easy. Setting up appropriate alerts is an ongoing process, what you get out of alerting is rather equal to what you put into it.

Alternatives Considered

Nagios Core

I have been using Nagios for 10+ years, so I am very familiar with it. The learning curve with SolarWinds was more difficult for me to pick up than Nagios and it wasn't as easy (at first) to duplicate, edit, etc. in SolarWinds. I genuinely think Nagios is a great product for many reasons, one of which is the unbeatable price.

SQL Sentry offers more features and is customize-able to fit our business needs. It has more centralized management and support. The company's technical support is also top notch. It is also worth mentioning that SentryOne Team Blog is an excellent source. One can find lots of valuable troubleshooting skills on the blog site - very educational and informational.

We are running 25 instances through a single monitoring service and it is able to keep up. We are finding that this many instances in our environment is about as many as can be handled. We will need to deploy additional monitoring services. Luckily, there is no additional licensing costs to deploy additional monitoring services. For us, it's just an additional Azure VM.

Return on Investment

Nagios Core

  • Much better network device performance metrics allowing to troubleshoot and do before/after changes comparisons
  • Has helped us to integrate with our Service Management tool (through other 3rd party tools)
  • Important part of our overall network health dashboard providing granular details at the device level (not end-to-end performance)
  • Cost is very convenient
Manuel Ayala | TrustRadius Reviewer

SQL Sentry

  • Better customer service as it alerts me automatically to loss of service issues so I can react and either get things fixed before it impacts the customers or to let my management know as soon as possible
  • It helps me find expensive SQL so our customers get better performance and we make better use of our resources
