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.

Provides a good view of the sequence and offers in-depth visibility into my infrastructure
I needed to identify the sequence and frequency of system calls for a specific system. Sysdig provided this information readily. However, analyzing frequency proved more challenging. As far as I know, Sysdig Monitor lacks functionality to directly obtain system call frequency for certain files. Therefore, I had to capture a screenshot of the relevant data from Sysdig Monitor and then manually extract the text. A built-in Sysdig feature to retrieve system call frequency for specific website actions would greatly enhance its usefulness. I had difficulty installing Sysdig Monitor on Windows.

Quotes from Members

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

Pros

"This is a very good solution and it is simple to use, for any company."
"It is an open-source platform with valuable features for performance and stability."
"Nagios XI is a simple monitoring tool with performance management."
"The alerting system is very effective."
"Nagios XI is stable."
"You want to monitor a specific metric that nobody else has? You can do it even with the most basic of scripting skills, and you can always share it with the vast community of Nagios Exchange."
"I can monitor a phone on a desk to very big servers of any company."
"Though I downplayed the administrative NCC GUI, this is by far the strongest aspect of the Nagios XI product."
"Docker containers are completely supported, kind of like "first class citizens"."
"The ability to stop/pause and capture logs when something happens is the most valuable feature."
"Sysdig Monitor impressed me with its in-depth visibility into my infrastructure."
 

Cons

"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."
"They need more documentation for the plugins."
"The product uses the backend as Perl and could be modified to a more lightweight solution like what's being offered by other vendors."
"Nagios XI can improve network and hardware monitoring, these parameters should be simplified to allow usage for monitoring. Additionally, if there was automatic reporting it would be helpful."
"The scalability of Nagios XI is scalable. However, it is not easy to do."
"The tool's AI model needs to be fixed."
"The product does not have SAP monitoring."
"The product's stability could be even better."
"I had difficulty installing Sysdig Monitor on Windows."
"It is needs to automate the actions to take when an alert is triggered."
""Events" reporting (errors, crashes, etc.) is not clear at all in a Mesos environment (i.e., it's not clear what specific container is the one that went down). In a Docker Compose environment, it may be way better."
 

Pricing and Cost Advice

"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"This solution is very expensive, at approximately $5,000 USD when I purchased it, which is why I haven't upgraded my version in several years."

"Licensing costs are reasonable."
"The licensing fees for this solution are approximately $3,000 USD per year."
"Nagios XI is open source."
"For our country in North Africa, it's expensive and we could purchase another solution for that price. But it's a reasonable price if we're speaking in international terms."
"Sysdig Monitor is not expensive."

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…
