NetFlow monitoring has improved operations but needs better configurations
For the implementation part, I am facing issues when configuring the business view. When I create the business view, I experience problems with the port interface. When I add the interface, I am confused about which interface is connected to which endpoint. If identifying the interface was easier, it would take less time to configure. Another issue is with threshold values; sometimes, it shows kilobytes (kB) while our threshold is set to gigabytes. This can be confusing. Improving this aspect would be beneficial. In URL monitoring, there is room for enhancement.

Effective alerting enhances network monitoring experience with an easy setup
We love Nagios XI due to the fact that JPS Web is very useful. JPS monitors the modem and performs switching, monitoring the computer, and performing switching. We implement some applications and traffic monitoring. The alerting system is very effective. For instance, if we have an alarm on some RAM storage if the traffic is cut or dropped.

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

"The most valuable feature of ManageEngine OpManager makes it easy to monitor all the network alerts on the application."
"The tool is useful for SNMP monitoring."
"The solution is finely stable."
"Defining thresholds and other alerting criteria is fairly simple and would not require a lot of training. This is very useful if you are managing a large environment."
"You can put all of your work on there, they'll send you an email or send you a text. That functionality as a network engineer is the one I like the most. I do like the fact that we can schedule reports. That works too because that's a lot fewer spreadsheets that I have to create."
"I liked Network Configuration Manager. They had some pretty decent features there, and they also had pretty good monitoring and alerts."
"Overall, I give the product a rating of ten."
"Device backups are smooth and managed centrally, with a nice dashboard, so you can quickly see the status."
"The solution is pretty stable."
"It is an open-source platform with valuable features for performance and stability."
"I can monitor a software made in-house to software of bigger companies."
"Since this is an open source technology, if we are capable of writing the plugins in any scripting language, this product allows us to monitor anything we want."
"Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried."
"We love Nagios XI due to the fact that JPS Web is very useful."
"Nagios XI helps us monitor the bandwidth of the internet connection, HTTP, DNS, active directory services, and exchange data availability. We have multiple servers to monitor databases, availability of servers, and ping."
"The solution's most valuable feature is its simplicity."
"Good compilation of the system's information."
"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."
"The up-to-date graphs and the history are very good."
"I would boldly say that this is the most scalable network monitoring tool that I know of"
"PRTG Network Monitor helps us quickly and easily discover a large number of sensors, so we can spend minimal time monitoring customer sites."
"I like the mobility of the PRTG Network Monitor and ITOps Dashboard."
"PRTG Network Monitor is easy to set up."
"Ease of set-up – it is quick and easy to add a probe and start collecting data from a device."
 

Cons

"WMI and SNMP integration with the domain controller should be seamless"
"The dashboard could include more features."
"We get a lot of false alerts."
"You cannot resolve 100 percent of the issues yourself. You would need to reach out to the support. It needs to be cheaper."
"We had some stability issues at the outset that have since been resolved."
"There should be an option to get mobile notifications or SMS mirror notifications for critical issues. That way, when we don't have access to email, we can still receive notifications via our phones."
"The two views into the system are very good but could be extended to further customization to fit the need of end users in a variety of roles."
"Needs an OVA, or more support for virtual deployments. Building a virtual instance of OpManager and OpManager Probe was a bit difficult because there was no OVA available."
"The way Nagios displays information isn't easy for a new user to understand. It's not intuitive enough. You need to read some tutorials or be trained to understand what it's displaying. Also, I think it needs more features to improve network visibility because there are some things you can't detect."
"The user interface needs improvement. Many tools have poor user interfaces, making them hard to manage and navigate."
"The technical support is variable - sometimes I get answers, but most of my tickets go unanswered."
"It can be quite difficult to know which drivers and agents to use when setting up."
"The Configuration Wizard needs improvement, because not all vendors are present."
"The product does not have SAP monitoring."
"Nagios XI can improve its GUI for users with a new look."
"The product could be optimized to improve the administrative user experience via the Nagios Core Configuration (NCC) GUI module."
"We would like more cloud native sensors for AWS, Azure, Google Cloud, etc. A lot of businesses are moving in that direction, so having something where we can pull performance stats out of these cloud services would be great for us."
"PRTG Network Monitor can improve the reports. In the reports, you have to give an alert for that SMS and email, the emergency calls and downtimes have to be reported accordingly. You have to enable email services or an SMS gateway service to receive more alerts at the proper time."
"When using PRTG Network Monitor it is beneficial if you have prior experience with it, the user interface could improve."
"They should work on syncing the solution with Gmail."
"The user interface could be more modern as it is quite dated. PRTG Network Monitor can sometimes be too detailed and cluttered at the beginning, making it heavy to use."
"The remote probes seem to be a little bit buggy at times. They just stop working or they say they can't communicate. What we tend to do to is install the remote app onto the servers that we use. That seems to clear it up."
"It would be nice if it gave us alerts via Gmail or SMS message."
"The technical support service should be improved."
