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

"I can monitor a software made in-house to software of bigger companies."
"Nagios allows us to configure any device so that we can send pager alerts when people don't have access to emails. It also allows us to schedule downtime and maintenance."
"Though I downplayed the administrative NCC GUI, this is by far the strongest aspect of the Nagios XI product."
"The solution has a lot of plugins and scripts integrated with it."
"Nagios is a custom API manager, and we can expose custom APIs for our integration. This is a great feature."
"An excellent solution that is easy and intuitive to implement."
"The dashboard allows you to see what's going on in the overall system."
"Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried."
"Docker containers are completely supported, kind of like "first class citizens"."
"Sysdig Monitor impressed me with its in-depth visibility into my infrastructure."
"The ability to stop/pause and capture logs when something happens is the most valuable feature."
 

Cons

"The interface could be more user-friendly."
"The pricing has recently risen. I know they've changed what is covered under the license, however, it doesn't change the way we use it and adds nothing to our experience, and yet we now have to pay more."
"Nagios XI can improve its GUI for users with a new look."
"It can be quite difficult to know which drivers and agents to use when setting up."
"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."
"I would like to see more customization in the network map because it is a bit tricky to use it."
"Technical support is an area that needs improvement. It is not available 24/7."
"The user interface needs improvement. Many tools have poor user interfaces, making them hard to manage and navigate."
"I had difficulty installing Sysdig Monitor on Windows."
""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."
"It is needs to automate the actions to take when an alert is triggered."
 

Pricing and Cost Advice

"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."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"Nagios XI is an expensive solution."
"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."
"The licensing fees for this solution are approximately $3,000 USD per year."
"We are using the free version of this solution."
"For the cost of the commercial product and support, and taking into account the open source characteristics of it, I believe it is difficult to a better value."
"The pricing is high with separate licensing for the product and support."
"Sysdig Monitor is not expensive."

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
