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 reduced troubleshooting time and improved issue detection through sensor alerts and team collaboration
PRTG Network Monitor can be improved because the dashboard themes feel outdated. It should be updated to a newer version for the new Gen Z customers. The notification sound options are limited unless customized. Restarting probes after Windows updates is necessary, and there should be some kind of automatic restart. The initial auto-discovery added too many unnecessary sensors, so auto-discovery should only take the necessary sensors into consideration.

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."
"The alerting system in Checkmk really works properly."
"Checkmk helps me compare data and foresee issues."
"Checkmk was built on a platform that was user-friendly, and I could build my charts easily."
"We can monitor multiple sites using the product."
"The most valuable features of Checkmk are its resource monitoring, infra monitoring, and log factor configuration."
"I really like the auto-discovery feature."
"Overall, from one to ten, I rate Checkmk a nine."
"It's great that we can create a dashboard inside software monitoring, and access many other websites, it is a complete monitoring solution."
"Stability-wise, I rate the solution a ten out of ten."
"The real-time monitoring and alerting are its most valuable features."
"We are using the basic PRTG that we can download for free, and PRTG is much cheaper than SolarWinds."
"The most advantageous aspect of PRTG Network Monitor is that you can start quite fast because there are many sensors you can use, and it's ready to use."
"We did some research, found PRTG, and I spoke to another company that used it, they really loved it so we went ahead got the free license initially, did a trial, found it absolutely amazing, and then bought it."
"If you need a simple and solid tool, and you're willing to spend a buck, it's a good option to consider."
"We can see which fiber links have been used heavily and, if they are used heavily, we can introduce more links to particular buildings or particular areas."
 

Cons

"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."
"I think that the integration and the exporting of the data collected are areas where Checkmk lacks but should try to improve the most."
"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."
"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 allow running scripts at varying intervals."
"The possibility to export the part of the sensor we made would be helpful."
"The clustering aspect needs improvement, as there is a bit of confusion about you do when hit that 5000 probe mark."
"A room for improvement in PRTG Network Monitor is its sensors. Its application technology sensor, such as the IAS, .NET, etc., needs some improvement because it doesn't work as expected."
"We need something that is more predictive. We would prefer if it wasn't a solution that was corrective and instead offered predictive insights so that we can handle problems before they even occur."
"It needs to have more monitoring on end-user devices."
"Needs ability to monitor standard notification time (notify after X time)."
"Scalability is the only major sticking point for me. There is a recommended number of sensors, which is around 10,000 and we're double that... The only option we have to scale is to buy another core, which would be a separate, stand-alone instance..."
"Having a Unix implementation or Unix installation could be an improvement. Right now, it's based just on Windows, and that's a problem for some customers."
 

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 price of PRTG Network Monitor is reasonable for the features that the solution provides. They charge you per monitoring, not per node, it is per port that you need for a device."
"I'm paying something like €1000 per year for the maintenance. I've got unlimited sensors."
"I would like better pricing models for smaller businesses. The free version is fantastic, but it's too restrictive. If they could just get up to 200 sensors for a reasonable fee for on-premise, I would give PRTG my credit card right now."
"We have an unlimited license for this solution."
"In my company now, we are using the free version."
"We've got the unlimited package... I believe it was around the £15,000 per year mark."
"While I am not the person who deals with pricing, I would say that we pay around 1000 pounds a year."
"We are using the premium version of PRTG Network Monitor. The price of the solution is a bit higher than competitors but it is worth the extra money. However, it would be helpful if the price was lower."

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
I have researched a quite a few network monitoring tools which can be used for various monitoring purposes of not only the servers, but the intermediate routers as well. There are majorly three types of these softwares. Ones which are completely open-source, you can do almost anything you want…
