IT Administrator at a construction company with 201-500 employees
Utilizing data monitoring capabilities and scripting potential to optimize system management
I frequently program functions with PowerShell, and although Bash could be used, my specialization is in PowerShell. Two of us focus on programming in PowerShell for infrastructure optimization. I set up a dedicated server to run scripts every hour, generating files for Checkmk output. However, Checkmk does not allow running scripts at varying intervals. I am working on this in the raw version of Checkmk.

Has improved incident response with better root cause visibility and supports flexible on-call scheduling
Datadog needs to introduce more hard limits to cost. If we see a huge log spike, administrators should have more control over what happens to save costs. If a service starts logging extensively, I want the ability to automatically direct that log into the cheapest log bucket. This should be the case with many offerings. If we're seeing too much APM, we need to be aware of it and able to stop it rather than having administrators reach out to specific teams. Datadog has become significantly slower over the last year. They could improve performance at the risk of slowing down feature work. More resources need to go into Fleet Automation because we face many problems with things such as the Ansible role to install Datadog in non-containerized hosts. We mainly want to see performance improvements, less time spent looking at costs, the ability to trust that costs will stay reasonable, and an easier way to manage our agents. It is such a powerful tool with much potential on the horizon, but cost control, performance, and agent management need improvement. The main issues are with the administrative side rather than the actual application.

Quotes from Members

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

Pros

"Checkmk helps me compare data and foresee issues."
"The initial setup of Checkmk was easy...It is a very stable solution."
"It's versatile, scalable, and easier to use compared to other solutions like Nagios and OMD."
"Checkmk was built on a platform that was user-friendly, and I could build my charts easily."
"Overall, from one to ten, I rate Checkmk a nine."
"The alerting system in Checkmk really works properly."
"The most valuable features of Checkmk are its resource monitoring, infra monitoring, and log factor configuration."
"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."
"The initial setup was straightforward from my own experience, helping integrate within the application and service levels."
"The network map is crucial in identifying bottlenecks and determining what needs more attention."
"The installation step is pretty straightforward."
"The dashboards provide a comprehensive and visually intuitive way to monitor all our key data points in real-time, making it easier to spot trends and potential issues."
"The ease of use allowed me to get up to speed with log management since it's my first time using Datadog."
"For us to have visibility into our app stack and the hardware we run has been highly beneficial."
"Datadog has positively impacted my organization by allowing us to gather complete data instead of looking all over the place at incomplete data and actually make pointed determinations for fixing issues."
"If we have a large load for users using our basic Datadog, it will immediately fire off an alert notifying us either something's wrong or not."
 

Cons

"Checkmk does not allow running scripts at varying intervals."
"In Checkmk, the documentation can probably be improved a bit more."
"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."
"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."
"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."
"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."
"The initial setup is a bit complex."
"Interactive tutorials could be a game changer."
"Their security features could be improved. We looked at their Security Monitoring feature but it was early in its development. Datadog are just getting into the security space so I'm sure this will improve in the future."
"The largest pain point we've had with Datadog to this point was onboarding."
"We have recently had a number of issues with stability and delays on logging, monitoring, metric evaluation, and alerts."
"Datadog could make their use cases more visible either through their docs or tutorial videos."
"Lacks some flexibility in the customization."
"The pricing model can be quite complex and might benefit from more flexible options tailored to different organizational needs."
"While it’s powerful, the interface can feel cluttered and overwhelming for new users."
 

Pricing and Cost Advice

"Checkmk is a fairly reasonably priced solution."
"The price of Checkmk is cheaper compared to other enterprise products."
"The product is affordable."
"The solution is fairly priced but history and log storage can get costly depending on your needs."
"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."
"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."
"Licensing is based on the retention period of logs and metrics."
"It didn't scale well from the cost perspective. We had a custom package deal."
"The price of Datadog is reasonable. Other solutions are more expensive, such as AppDynamics."
"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."
"​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."
