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.

Unified monitoring has improved end-to-end visibility and reduced detection time across apps
When we have too many detectors in place for one particular app, such as when I have created 50+ detectors through my account, the entire page becomes a bit loaded when creating the 51st detector, feeling heavy and taking time to load. Additionally, it throws random errors; for example, when we try to save one detector, it might throw some random error which is not even related, with something else being wrong, not that particular error, but the underlying root cause might be different. Sometimes the error is just "some problem occurred," and we are not able to point out what the real cause is. This mainly happens when we have too many detectors or too many alerts in place rather than a standard number. One more thing is in the alert rules; if we have a main general alert, and instead of creating a new detector, we are adding a new rule under one detector, when the number of rules also increases, such as when we have 10 or 15 rules under one generic detector, that again creates the same kind of problem, taking some time to save that particular newly added rule, and it might not save at times, just keeps on spinning. Those are the two drawbacks which I spotted recently; other than that, everything looks perfect.

Quotes from Members

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

Pros

"Overall, from one to ten, I rate Checkmk a nine."
"Checkmk was built on a platform that was user-friendly, and I could build my charts easily."
"The most valuable features of Checkmk are its resource monitoring, infra monitoring, and log factor configuration."
"The alerting system in Checkmk really works properly."
"We can monitor multiple sites using the product."
"It's versatile, scalable, and easier to use compared to other solutions like Nagios and OMD."
"I really like the auto-discovery feature."
"Checkmk helps me compare data and foresee issues."
"The features of Splunk Observability Cloud that I prefer the most are its all-encompassing licensing model, which is comparatively better than others in the market."
"The best features in Splunk Observability Cloud are the metrics; I can see any logs or anything related to the server or services we want to monitor, and the metrics are a good function."
"After moving to Splunk Observability Cloud, it is almost zero downtime."
"The tool's stability is great."
"We utilize the APM and auto-detectors, as the core metrics and core alerts are available for us, which are the features of Splunk Observability Cloud that I appreciate the most."
"I have primarily used it to go back into the past and understand why something happened. It provides enough information to do research and figure things out."
"With the metrics collection, I can proactively find incidents and work on the major issues when they happen and predict these issues."
"Splunk Observability Cloud scales with the growing needs of my organization effectively."
 

Cons

"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."
"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."
"In Checkmk, the documentation can probably be improved a bit more."
"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."
"Unfortunately, with our current setup, we just have to implement Log Observer in a couple of instances so that we can have that integration with Splunk Observability Cloud."
"They can get more integration with a few more products. They can also update some of the dashboards that are in there now."
"The dashboards are used mainly to visualize information about the infrastructure, but it isn't easy to construct or use the dashboards. While we tried to resolve the issue by calling support, it would be easier if they had an AI co-pilot to identify the problem and help you solve it."
"It does not have a user-friendly interface and it is difficult to use."
"A wide variety of logging makes log onboarding difficult."
"There is not a lot of support for the tool's on-premises version, especially since everything is on the cloud."
"Particularly what we're having is disconnection from the cloud console, where we will be working in it and receive a message saying that we've been disconnected and have to wait for it to come up."
"We still use Splunk Enterprise licensing. A lot of the newer features go into Splunk Cloud before Enterprise. We're not looking to switch our licensing over, so we're falling behind on the newer features."
 

Pricing and Cost Advice

"The product is affordable."
"The price of Checkmk is cheaper compared to other enterprise products."
"Checkmk is a fairly reasonably priced solution."
"The pricing is reasonable."
"Splunk Observability Cloud is expensive."
"Splunk APM is a very cost-efficient solution."
"Splunk Infrastructure Monitoring is an expensive solution."
"The product is a bit expensive considering the competition but the company may negotiate the price."
"The solution's pricing is costly."
"Splunk's infrastructure monitoring costs can be high because our billing is based on data volume measured in terabytes, rather than the number of devices being monitored."
"Splunk APM is expensive."
