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 enabled us to detect issues instantly through alerts and monitor every service from a single dashboard
Splunk requires significantly more improvements compared to Splunk AppDynamics, specifically regarding the licensing aspect. Splunk renews licenses every six months, which is inconvenient. It would be better to have a one-year license to avoid needing to update keys constantly, which can only occur on weekends, making it a burdensome task. Although Splunk is better for certain use cases, Splunk AppDynamics is broader in functionality. Specifically, I want enhancements related to creating dashboards not only for logs or minor services but also for configuration levels, allowing us to check configurations immediately without manually opening the entire code when exceptions arise—a feature I wish to see improved in Splunk, although it may not be necessary for Splunk AppDynamics.

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."
"Overall, from one to ten, I rate Checkmk a nine."
"The most valuable features of Checkmk are its resource monitoring, infra monitoring, and log factor configuration."
"I really like the auto-discovery feature."
"It's versatile, scalable, and easier to use compared to other solutions like Nagios and OMD."
"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 alerting system in Checkmk really works properly."
"We can monitor multiple sites using the product."
"AppDynamics has a very broad range of supported technologies, and it's user-friendly. It looks nice, and it's easy to sell the solution to the stakeholders when we can visualize how the website is working. For example, where we have any problems through visual analytics."
"The most valuable feature of AppDynamics is Proactive Monitoring and Alerting."
"What I found valuable in AppDynamics Database Monitoring is good technical support. I also like that it's scalable and stable."
"The transaction snapshots let you find out where the application broke; it pinpoints where in the call stack, and then how long it took to resolve."
"This solution is easy to use and very powerful, it is a complete tool for us."
"AppDynamics Browser Real-User Monitoring provides smooth connectivity to different applications."
"We have seen application availability increase, and there is a twenty-five percent reduction of the application downtime."
"I like that AppDynamics allows every organization to have what they want to see, like for my organization, we're able to customize the dashboard to show us details of what we want to see in our transactions."
 

Cons

"It is easy for tech-savvy people, but newcomers might find it intimidating."
"The initial setup is a bit complex."
"Checkmk does not allow running scripts at varying intervals."
"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."
"In Checkmk, the documentation can probably be improved a bit more."
"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 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."
"Customization requires a few manual tweaks."
"Splunk AppDynamics requires multiple agents; if I have one server with multiple applications in different languages, then I need to instrument different agents for each application."
"Sadly, I did not see return on investment with Splunk AppDynamics."
"I would like to see accommodation for millisecond granularity, as we only have one-second granularity now."
"I would like to see a better way to automate actions based on the events generated by the tool."
"An improvement could be if the monitoring was able to be summarized into something more clear and simple for people who don't have the technical skills on the database side."
"I have found it sometimes a bit difficult to trace the transaction all the way through to the application. I'm not sure if that problem is on the database side or on the application side, but that would be something that I would like to be improved. The traceability from the application to the database, sometimes, is a bit of a challenge. If you're using AppDynamics, with the Java agent, for instance, you need to be able to trace it through."
"I could not find a user-friendly interface for querying, and analytics sometimes gives the wrong results...I feel that analytics could have been better in searching and running the analytical queries."
 

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."
"In terms of pricing, I feel that when you compare the benefits that we get to the price that we paid, it is reasonable."
"AppDynamics Browser Real-User Monitoring does have licensing cost associated with it."
"My understanding is that the price of this solution is quite high, compared to other products."
"It is expensive. However, our time to recover has been reduced, and this product has helped recuperate costs and provided us with ROI."
"Take into consideration what you get for specific pricing models and how much it costs to add on things you may need later.​"
"The pricing of the solution is reasonable for what features you receive."
"One of the main downsides to the solution is its cost."
"This solution is not the cheapest but it works well. You will end up doing more work with a cheaper solution than if you just spent the extra money on a better solution like this one."
