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

"The initial setup of Checkmk was easy...It is a very stable solution."
"Checkmk helps me compare data and foresee issues."
"The most valuable features of Checkmk are its resource monitoring, infra monitoring, and log factor configuration."
"We can monitor multiple sites using the product."
"I really like the auto-discovery feature."
"The alerting system in Checkmk really works properly."
"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."
"Datadog helps us detect issues early on and helps in troubleshooting."
"This is definitely a good product and I would consider them one of the leaders within the application monitoring and cloud monitoring space."
"Monitors have also been very valuable when setting up our on-call processes. It makes it easy to set up and adjust alerting to keep our teams aware of anything going wrong."
"Synthetic testing is by far the most valuable feature in our organization."
"The real-time data helps us make informed decisions and optimize our operations, ultimately enhancing our overall efficiency and performance."
"I like that you can build out a dashboard pretty quickly. There are some things that come out of the box that you don't really need to do, which is great because they're default settings."
"Datadog's seamless integration with Slack and PagerDuty helped us to receive alerts right to the most common notification methods we use (our mobile devices and Slack)."
"Its integration is most valuable because you can integrate it with various service providers such as AWS, .Net, etc."
 

Cons

"Checkmk does not allow running scripts at varying intervals."
"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."
"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 initial setup is a bit complex."
"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 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."
"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."
"The product could be improved by providing remote control to agents, enabling them to execute automation and collections without requiring another automation tool or integration."
"The pricing is a bit confusing."
"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."
"The sheer amount of products that are included can be overwhelming."
"I'm still exploring the trial version, and it is fine. One thing that I haven't been able to figure out is how to retrieve a report. This is something that could be improved. I probably need to navigate to a place to access the reports."
"I'd like to see better pricing and more integration in the next release."
"The hardest thing we experience is just training people on what to search for when identifying a problem in Datadog, and having some additional training that might be easily accessible would probably be a benefit."
"We did have an issue where a synthetic test was set up before the holiday break, and we were quickly charged a great amount. Our team worked with Datadog, and they were able to help us out since it was inadvertent on our end and was a user error."
 

Pricing and Cost Advice

"The product is affordable."
"Checkmk is a fairly reasonably priced solution."
"The price of Checkmk is cheaper compared to other enterprise products."
"It has a module-based pricing model."
"The price is better than some competing products."
"The tool is open-source."
"My advice is to really keep an eye on your overage costs, as they can spiral really fast."
"The cost is high and this can be justified if the scale of the environment is big."
"Licensing is based on the retention period of logs and metrics."
"At my last company, we did see ROI, specifically around response time. We could get to mission critical things that were down and losing revenue on immediately. So, the product paid itself back."
"​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."
