Single pane of glass, easy to share dashboards, and good for monitoring
We've had some issues where we had Datadog automatically turned on in AWS regions that we weren't using, which incurred a small but steady cost that amounted to tens of thousands of dollars spent over a few weeks. I wish there was a global setting that lets an admin restrict which regions DD is turned on in as a default setup step. Sometimes, the APM service dashboard link isn't sharable. I click something in the service catalog, and on that service's APM default view, I try to share a link to that with a teammate, and they reach a blank or error screen. I wish there was more organization and detail in the suggestions when I use the query editor. I'm never quite sure when the autofill dropdown shows up if I'm seeing some custom tag or some default property, so I have to know exactly what I'm looking for in order to build a chart. It's hard to navigate and explore using the query autofill suggestions without knowing exactly what tag to look for. It's been a bit hard to understand how data gets sampled or how many data points a particular dashboard value is using. We've had questions over the RUM metrics that we see and we had to ask for help with how values are calculated, bin sizes, etc to get confidence in our data.

Effective alerting enhances network monitoring experience with an easy setup
We love Nagios XI due to the fact that JPS Web is very useful. JPS monitors the modem and performs switching, monitoring the computer, and performing switching. We implement some applications and traffic monitoring. The alerting system is very effective. For instance, if we have an alarm on some RAM storage if the traffic is cut or dropped.
Jeff Cronstrom - PeerSpot reviewer
A highly stable solution that can be used to monitor system availability
The most valuable feature of Opsview is the ability to clone the services when you're monitoring something out of the test setup. You can clone that service, and it allows you to add new services quickly. You can bring up new servers, and you can easily add them. Also, there's an API to be able to add services as well. We don't use the API. We mostly use the cloning function because it stores everything in a back-end database. The underlying monitoring platform for our version is Nagios. That's where we upgraded from Nagios to Opsview.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"I like the amount of tooling and the number of solutions they sold with their monitoring. Datadog was highly intuitive to use."
"The most valuable feature I have found is the elastic container service."
"Datadog provides tracing and logging, whereas Dynatrace focuses on tracing, and Splunk is more of a logging tool. Datadog's advantage is that we don't need two tools."
"It is easy to implement and scale applications with standardized visibility, monitoring and alerting"
"Our primary alerts, based on metrics and synthetic transactions, are the most used and relied upon for decreased MTTA/MTTR across all of our platforms. This is followed by deep log analysis that enables us to quickly and easily get to a preliminary root cause that someone on the infrastructure, platform or development teams can take and focus their attention on the precise target that Datadog revealed as the issue to be remediated."
"Session recordings have been the most valuable to me as it helps me gain insights into user behaviour at scale."
"I have found some of the most valuable features to be the way things all come together that gives us a point of view that is useful. The panel is very beautiful and customizable."
"It brings in observability, monitoring, and alerting capabilities - all of which we need to operate at scale."
"The ability to set up templates and groups of checks, as well as customize the checks themselves."
"Since this is an open source technology, if we are capable of writing the plugins in any scripting language, this product allows us to monitor anything we want."
"Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools."
"The most valuable features of Nagios XI are you can customize it based on your use case and requirements. It is flexible and easy to integrate with our systems. You can customize the solution by adding additional features using code."
"The installation is no problem. I've installed Nagios several times."
"Nagios is a custom API manager, and we can expose custom APIs for our integration. This is a great feature."
"The solution's most valuable feature is its simplicity."
"It is an open-source platform with valuable features for performance and stability."
"I am satisfied with the overall product since it works well…It is a stable solution."
"What was very compelling about OpsView was that we could dial out the noise and have meaningful and actionable alerts."
"The most valuable feature of Opsview is the ability to clone the services when you're monitoring something out of the test setup."
"We use this solution for internal monitoring our own cloud platform because we are a public cloud provider. We also use it for monitoring purposes on behalf of our clients."
"It's a good solution. It covers all aspects of monitoring purposes."
 

Cons

"When I started using it years ago, it had stability problems. I remember, specifically, we ran everything in Docker containers. There were some problems getting it into a Docker container with very specific memory limits."
"There are things about it that we would like to be fixed, such as it is taking averages of average. This results in data that we don't expect."
"ECS could be improved by including more tutorials for beginners to reduce the barriers to entry."
"Lacks some flexibility in the customization."
"Presently, the billing CSV reports provide insights into billing-related information yet are somewhat limited in functionality, typically offering reports with only three columns."
"There is occasional UI slowness and bugs."
"I found the documentation can sometimes be confusing."
"They need to implement template variables into the message response body."
"The product uses the backend as Perl and could be modified to a more lightweight solution like what's being offered by other vendors."
"Nagios XI can improve network and hardware monitoring, these parameters should be simplified to allow usage for monitoring. Additionally, if there was automatic reporting it would be helpful."
"From an alerting point of view, some graphics and metrics don't work properly with Nagios XI as they do with Checkmk."
"The reporting part should be made simpler. While we can obtain all the reports we need, we always have to create work-arounds to get them."
"There's room for improvement in the visibility, and in the ability to extract information. Stuff like this should be more simple."
"The user interface needs improvement."
"I would like to be able to extend it to all of our data centers, whether they are in the cloud or not. It would be helpful if I could connect everywhere."
"I would like to see support for notification via SMS."
"Maybe the graphical representation can be improved. It can be enhanced for better visualization. It could be a little better. And the graph center can be improved."
"Some of the graphics on Opsview could be improved."
"Pricing and a few certain aspects in the solution needs to be improved."
"Customized reporting can be improved."
"In a future release, we would like to have Observ for AI. Any AI and intelligence it can add to the monitoring is obviously beneficial. We would also like to have automated callouts."

"The solution's pricing depends on project volume."
"It costs the same amount it would if we were hosting it ourselves, so we are incredibly happy with the cost."

"​Pricing seems reasonable. It depends on the size of your organization, the size of your infrastructure, and what portion of your overall business costs go toward infrastructure."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
