Paolo Sala - PeerSpot reviewer
A reasonably priced tool for system and application monitoring
The main room for improvement is in the solution's presentation and the integration area. In our company, we use the integration capabilities from ServiceNow. We also have another big monitoring solution in place in our company, which is Dynatrace. At the moment, there doesn't exist an out-of-the-box integration for Dynatrace. 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 only implementation of Checkmk that allows high availability is the virtual appliance that has the option for the availability of a different box. Otherwise, you have to find a way to implement it manually with some custom solution, which could be an improvement.

Detects suden changes but significant pricing concerns affect the effectiveness of network traffic troubleshooting
We use PRTG Network Monitor for monitoring traffic on interfaces and the behavior of network traffic. If there are sudden changes in traffic or any configuration issues, we can sort them out using PRTG. It's very helpful for troubleshooting and monitoring traffic utilization on our interfaces…

Quotes from Members

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

Pros

"Checkmk was built on a platform that was user-friendly, and I could build my charts easily."
"Checkmk helps me compare data and foresee issues."
"The initial setup of Checkmk was easy...It is a very stable solution."
"I really like the auto-discovery feature."
"The alerting system in Checkmk really works properly."
"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."
"We can monitor multiple sites using the product."
"The tool is integrated with our email for the alerts."
"There was only one feature I liked about PRTG Network Monitor a lot, and that was bandwidth monitoring, though, in the newer versions of the tool, that feature is now a bit lacking. Pricing for PRTG Network Monitor is also not as expensive. It's a good tool, even for beginners."
"The sensors and probes are great, nice and lightweight, they don't take up too many resources on the system. We just deploy them out and they start reporting instantly."
"The most valuable feature is the notifications. As long as you spend time and think about what and when you want to be notified, it's always accurate. It is always there. I find things out before my Internet provider."
"PRTG Network Monitor is perhaps the most accurate tool we have used to monitor the capacity of the WAN connection."
"It improves the status of my infrastructure, from networking devices to real-time machines."
"It is a user-friendly solution."
"PRTG is relatively intuitive and fairly straightforward. It has net flow monitoring and that works all right. I would describe it as a decent middle-of-the-road solution."
 

Cons

"The initial setup is a bit complex."
"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."
"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."
"In Checkmk, the documentation can probably be improved a bit more."
"Checkmk does not allow running scripts at varying intervals."
"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."
"It is easy for tech-savvy people, but newcomers might find it intimidating."
"They could improve the process of updating the license."
"Performance-wise, PRTG Network Monitor still needs improvement because a large number of SNMPv3 queries reduces tool performance."
"The free version only gives us 100 free sensors to use. It would be nice if there was double that."
"In our organization, we encounter performance issues with our PRTG probe service. I saw documentation from the vendor or Paessler mentioning that there are limitations for WMI sensors. Other than that, we are okay with PRTG."
"Their penetration within the market could be much better. If their pricing was lower, even though it's reasonable now, it might help them achieve this."
"The inventory of the device should be improved."
"PRTG Network Monitor should provide syslog monitoring since it is not available at this time. There are very limited features as compared to other solutions."
"It would be nice if it gave us alerts via Gmail or SMS message."
 

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."
"I rate the price of PRTG Network Monitor an eight on a scale of one to ten, where one is a high price, and ten is a low price."
"We pay for a perpetual license and we have a support fee."
"The licensing fees are billed annually and there are no costs in addition to this."
"When you buy PRTG, everything comes in one bundle. Licensing is very easy."
"The pricing is reasonable for the features provided."
"We bought a license for 4000 sensors."
"It is expensive."
"It's an annual license that is based on the number of endpoints that we're tracking and using."
