Technology has becomes one of the most, if not the most important development that makes lots of our activities becomes simpler and in this era where everything is about convenience, we also seek for the best way to do various things including business. Smart device applications is becoming a huge commodities today and offered by a wide range of companies both from those huge scale multi-millionaire house to those just recently building their businesses. The shape of traditional and modern business might be different but all need continuous monitoring.
With the huge demand of monitoring service, there is another similar business which is offering solution for those users who have to manage and keep an eye on their services all the time and it is SaaS or Software as a Service. We are sure this term is familiar to those who are working in the IT industry because the market has been so well developed for this business type or service that it is currently offered by a growing number of providers.
From the provider’s point of view, this is a very promising market to make a huge profit especially with the increasing demand from other companies while from the user’s side, these tools are reliable and convenient to apply on their monitoring system. The best and most interesting benefit in our opinion however, is how they eliminates the need for business to download and maintain the software by themselves since we can access them through the internet, anytime as long as there is data coverage in the area.
If you are not sure yet about SaaS convenience or benefit that will makes your monitoring job easier, here are some most common reasons why other users are relying on them.

- Next is it eases upgrading and maintaining the services since it can be time consuming and inconvenient. With SaaS we don’t have this responsibility including to upgrade the service or its security.
- Another benefit we enjoy from the system is its ability to integrate seamlessly with the existing website and should be able to adapt easily as well to the way our application or business run. Additionally they are customizable thus, we can use the features that we need only.
- Last but not least is the fast deployment and decisions for they are readily being used anytime compared to when doing internal efforts and then, most of them offer free trial for users to get used to or see how the service will work on their system before committing.
About Datadog and Nagios
For those whose business is providing applications, SaaS is a nice system to try as your monitoring tools and they can ease your workload as well as making things more convenient for the team. There are lots of providers out there but most of them especially the well-known ones are reliable depending on each user’s preferences. Some of them are also free to use with some limitations for small businesses to try or utilize which is great so we don’t have to spend additional cost to enjoy the benefits.
Among all of those SaaS that are designed to monitor your applications, Datadog and Nagios are two of the top 10 monitoring service today because they are equally reliable and are equally nice choice to help your team view the metrics in real-time. Comparing the two from popularity and market share part, it is easy to say the latter is currently leading the game but there are actually lots of other similar options as well in the market yet, these two are still being our favorites.
Both of them are server monitoring tools and they will be able to monitor process as well as pull some process level metrics. Nagios is probably the most mature free-tools out there and its brightest part besides the reliability is how many plugins here that have been written by the experts and some enthusiasts as it has been running for decades. Datadog on the other hand is fairly new in comparison but many love this service because of the features and continuous added capabilities.
The most prominent difference between them is that Datadog is cloud based and is probably the most convenient for anyone who reach for simplicity because this is what the service will offer to you. Additionally, we can call it as APM tool as well to provide deep diagnostic required for troubleshooting in which Nagios is capable as well but won’t be as convenient for it will need more customization.

Datadog and Nagios Price
Just like every business decisions, everything require a sacrifice of assets will need a thorough calculation first so we can make sure the cost is not going to harm your profit. Let’s start with Datadog since they provide lots of services in the catalogue and depending on what you are looking for, the infrastructure that centralize your monitoring system itself can be free but up to 5 host only and with limited features while the paid version start from $15 to $25 per host, per month.
Moving to Nagios, they also have different products for different users and they separate the free to the paid version as well. The free version is called as Nagios Core and this require an expertise or technical resource to use or understand which Nagios XI simplified and making it better for non-technical people to utilize properly. Their difference revolve in ease of use as well as convenience suggesting the XI is built for everyone and in general more business oriented.
Talking about the paid version or Nagios XI, this service has two level of Standard and Enterprise Edition starting from $1,995 to $3.495 billed annually and there are different level of nodes license as well from 100 nodes to unlimited and it is starting from $1,995 to $19,995. Node itself is anything with IP address that we want to monitor such as switches or routers.
Datadog and Nagios Setup/System Requirement
While Datadog and Nagios are designed to be convenient it doesn’t mean that they are not going to require any effort as well yet, it is highly depending on what you are monitoring. Starting with Datadog, it will require you to install and configuring a software agent which is available for a host of platform including OS X, Chef, Debian, Win 10, etc. then we can run MSI to prompt the API key provided. In Linux, the agent itself can be accomplished in several way like pasting the pre-formatted command into the Terminal command line.
As with Nagios XI, there are some requirement we have to meet first including 20GB of free hard drive space, 2 GB memory or more, at least 2.4 GHz CPU, CentOS or RHEL ver. 5/6/7, and MySQL with PostgresQL when running versions less than XI 5. Additionally, depending on how many nodes or services being monitored, at least we have to have 40 GB disk space with 1-2 cores, and 1-4 GB RAM for 50 hosts while those who manage more than 500 hosts will need at least 120 GB of disk space and more than 8 GB of RAM.
Datadog and Nagios Monitoring
As a monitoring service, Datadog is capable of monitoring and alerting on several different source with different levels of details depending on what it is currently monitoring, the service will be able to incorporate log files, performance metrics, availability, and a huge sum of information. Similarly, Nagios also has diverse monitoring capabilities such as performing active/passive host checks, service checks, collecting various types of information, monitoring applications, and many more. In addition its add-ons are going to further increase the monitoring ability of this service.
Datadog and Nagios Dashboard
Another thing we love from the monitoring side is the ease of use itself because both of Datadog and Nagios are providing interactive dashboard through your web browser and the best part is they are customizable and easy to understand with lots of visualization to help user understand their application status better. In comparison we do like how they build the layout in Datadog better because it seems more attractive, easy to use, and understand even from non-technical person view.
What’s better is Datadog has two dashboard style; TimeBoards and ScreenBoards to facilitate different monitoring. The first is used for troubleshooting efforts while the latter is more into the monitoring function since it shows the current status and performance information.
Datadog and Nagios Notification
Besides the monitoring purpose, Datadog and Nagios also have the alerting feature that are equally reliable. Starting with the former, this service will allow you to configure alerts on one device or a group of similar device as well as be activated based on things like storage capacity reaching certain point or certain amount of failed login attempts within a span of time. Nagios on the other hand can send the alert with Email or SMS and also offer filtering options.
These filtering options unfortunately only available for certain types of alerts including recovery, dowm, acknowledgement, unreachable, downtime for host, and flapping. As for the notifications messages, they can be further customized while sending test notifications is supported as well.
Datadog vs Nagios
|- More expensive||- Affordable|
|- Free up to 5 nodes||- Free up to 7 nodes|
|- Already have APM||- Not yet offering APM|
|- Better dashboard||- Less attractive dashboard|
Datadog and Nagios are two reliable monitoring tools you may want to try but they are also different because the former is native in cloud based services. The information provided are numerous depending on what you want to monitor but we do like the kind of dashboard provided by Datadog because it seems easier to understand and convenient. Additionally, Datadog already includes APM with support for end-to-end tracing and container monitoring. For the free version, Datadog is free up to 5 nodes and Nagios is free up to 7 nodes.
All in all both of them are worth to try which we do recommend because different needs may have to use different solution but in comparison, we do like how Datadog integrate and show the information than Nagios.
