Featured Reviews

Paolo Sala - PeerSpot reviewer
A reasonably priced tool for system and application monitoring
The main room for improvement is in the solution's presentation and the integration area. In our company, we use the integration capabilities from ServiceNow. We also have another big monitoring solution in place in our company, which is Dynatrace. At the moment, there doesn't exist an out-of-the-box integration for Dynatrace. I think that the integration and the exporting of the data collected are areas where Checkmk lacks but should try to improve the most. The only implementation of Checkmk that allows high availability is the virtual appliance that has the option for the availability of a different box. Otherwise, you have to find a way to implement it manually with some custom solution, which could be an improvement.
Kevin Palmer - PeerSpot reviewer
Useful log aggregation and management with helpful metrics aggregation
Datadog provides us value in three major ways: First, Datadog provides best-in-class functionality in many, if not all, of the products to which we subscribe (infrastructure, APM, log management, serverless, synthetics, real user monitoring, DB monitoring). In my experience with other tools that provide similar functionality, Datadog provides the largest feature set with the most flexibility and the best performance. Second, Datadog allows us to access all of those services in one place. Having to learn and manage only one tool for all of those purposes is a major benefit. Third, Datadog provides significant connectivity between those services so that we can view, summarize, organize, translate and correlate our data with maximum effect. Not needing to manually integrate them to draw lines between those pieces of information is a huge time savings for us.

Quotes from Members

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

Pros

"It's versatile, scalable, and easier to use compared to other solutions like Nagios and OMD."
"Overall, from one to ten, I rate Checkmk a nine."
"The most valuable feature of the solution is that it has a lot of different pieces, and they all work together...It is a very scalable solution. Scalability-wise, I rate the solution a ten out of ten."
"We can monitor multiple sites using the product."
"The most valuable features of Checkmk are its resource monitoring, infra monitoring, and log factor configuration."
"The initial setup of Checkmk was easy...It is a very stable solution."
"Checkmk helps me compare data and foresee issues."
"The alerting system in Checkmk really works properly."
"We integrate our application logs. It is great to be able to tie our metrics and our traces together."
"Datadog agents act as an integration to different services, providing easy access and management."
"Synthetic testing is by far the most valuable feature in our organization."
"The most valuable feature of Datadog is its logs."
"Sometimes it's more user friendly for development teams. There are some parts of Datadog that are more understandable for development teams. For example, the APM in Datadog works more manually and works like the tools in New Relic or Grafana, or Elastic. It is easier to understand for software development teams."
"The CCM, Workflows, Logs, APM, and RUM are all useful aspects of the solution."
"We have way more observability than what we had before - on the application and the overall system."
"It is easy to implement and scale applications with standardized visibility, monitoring and alerting"
 

Cons

"I think that the integration and the exporting of the data collected are areas where Checkmk lacks but should try to improve the most."
"Checkmk does not allow running scripts at varying intervals."
"In Checkmk, the documentation can probably be improved a bit more."
"The main challenge for us is that we're moving from Nagios to Checkmk, and we're still getting used to the new way of working."
"Sometimes we receive alerts, and it can become annoying when you acknowledge an alert. It is very clunky when you acknowledge the alert. The process is not very intuitive, and there are instances where it feels a bit cumbersome to acknowledge an alert."
"Checkmk does not work too easily with the PowerStore. I use a PowerShell script as Checkmk runs on Linux and a Windows system, connecting with the Checkmk agent."
"It is easy for tech-savvy people, but newcomers might find it intimidating."
"If an alert is generated for a specific pattern in the log, and if Checkmk catches that log, it will stay there even after the alert is resolved."
"More helpful log search keywords/tips would be helpful in improving Datadog's log dashboard."
"At the beginning, when we started throwing logs at it, there was a bit of hiccup. However, this was during their beta period, so hiccups were expected."
"It is far too easy to run up huge unexpected costs."
"While I like the ease of use, when compared with Tenable Nessus they could still improve their usability."
"A big problem with Datadog is the billing. They need to make the billing more user-friendly."
"We have contact with many customers that cover many areas, so we have cases where the infrastructure administration could be improved."
"I've found that the documentation is lacking in certain regards."
"Even though it is powerful on its own, the UI-based design lacks elegance, efficiency, and complexity."
 

Pricing and Cost Advice

"The price of Checkmk is cheaper compared to other enterprise products."
"Checkmk is a fairly reasonably priced solution."
"The product is affordable."
"The pricing and licensing through AWS Marketplace has been good. It would be nice if it was cheaper, but their pricing is reasonable for what it is. Sometimes, for their newer features, they charge as if it's fully fleshed out, even though it is a newer feature and it may have less stuff than their other items."
"The price of Datadog is reasonable. Other solutions are more expensive, such as AppDynamics."
"They prefer monthly subscriptions."
"I am not satisfied with its licensing. Its payment is based on the exported data, and there was an explosion of the data for three or four weeks. My customer was not alerted, and there was no way for them to see that there has been an explosion of data. They got a big invoice for one or two months. The pricing model of Datadog is based on the data. The customer was quite surprised about not being alerted about this explosion of data. They should provide some kind of alert when there is an increase in usage."
"Datadog does not provide any free plans to use the solution. When I start with a proof of concept it would be sensible to have a free plan to test the tool and check whether it fits the requirements of the project. Before the production stage, it is always good to have a free plan with some limited features, number of requests, or logs."
"It has always scaled for us. Cost scales up too, but that is not necessarily a bad thing. It's reasonable for what they're providing."
"The solution is fairly priced but history and log storage can get costly depending on your needs."
"Pricing and licensing are reasonable for what they give you. You get the first five hosts free, which is fun to play around with. Then it's about four dollars a month per host, which is very affordable for what you get out of it. We have a lot of hosts that we put a lot of custom metrics into, and every host gives you an allowance for the number of custom metrics."
