Senior System Administrator at Interactive Group
Monitoring solution provides comprehensive visibility across IT infrastructure
The good thing about Nagios Core is it covers everything. Everything in the IT domain, you can monitor anything. You can even monitor printers, the ports of printers, Core workstations, and storage. You can monitor the workflow Core and the utilization of computes. If you want to grasp everything of your IT equipment on a single interface, you can use Nagios. It's the best one. It provides dashboards, and you can also configure your emails and alerts with it. If something is critical, you can configure it to notify via emails. It has a very handy dashboard, providing live alerts and visibility for everything.

Senior Software Engineer at Unisys
Centralized monitoring has reduced outages and enables faster diagnosis across all database servers
The best features Redgate Monitor offers include detailed resource monitoring, instant alerts, and easy customization. A user can quickly see how your server is performing and which queries are taking the longest. The instant alerts and customizable options help since it is a multiple-platform database observability for the entire estate. I use this to optimize performance, ensure security, and mitigate potential risks with fast, deep-dive analysis and intelligent alerting. I love Redgate Monitor because it helps manage an entire database estate from a single pane of glass. Redgate Monitor has positively impacted my organization by creating database observability to proactively mitigate potential risks with instant problem diagnosis and customizable alerting. It accelerates daily database maintenance by automating time-consuming manual tasks, such as identifying long-running queries or tracking blocked processes, which frees up time to proactively improve the performance and security of servers. I have seen time savings from twenty percent to forty-five percent. It also helps to minimize downtime.

Quotes from Members

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

Pros

"We have used this product now for quite some time and we are happy with it."
"The solution's most valuable feature is that it offers proper alerting capabilities."
"The reporting structure and the feature set are valuable to me."
"The features of Nagios Core that we find most valuable are the plugins we use, we can check the uptime and see how many servers and routers and create groups accordingly."
"Nagios is able to minimize server downtime and this in turn helps to generate more revenue."
"Nagios doesn't get the respect it deserves; most likely due to the fact that it doesn't have a licensing cost."
"We mostly use Nagios Core to integrate with Python and Bash Script."
"This product covers all of our infrastructure health checks, and has triggers for us to alert us to any unusual behaviour of the monitored systems."
"Overall, I truly love Redgate Monitor and would recommend it to anyone in database administration, but I also recognize that improvements and upgrades, especially concerning its AI features, are essential for ongoing development."
"Redgate Monitor has positively impacted my organization by creating database observability to proactively mitigate potential risks with instant problem diagnosis and customizable alerting."
"Redgate Monitor has impacted our organization positively by helping us simplify day-to-day tasks and realize a feeling of security."
 

Cons

"I like to have the option to configure Nagios using the web interface."
"The dashboard should be improved."
"Don't use it. If you're starting from scratch, there are products that scale better and perform better, and they use the same plugin syntax as they were initially Nagios forks."
"Nagios Core is not easy to use, so I don't recommend it for everyone."
"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."
"Nagios Core can improve the graphical interface, it would make things a little easier."
"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."
"They should simplify the features so it becomes easier to setup out of the box."
"It is a bit expensive for MSPs to use for their day-to-day monitoring."
"For improvement, I think Redgate Monitor's alert customization depth could be enhanced; I would appreciate more granular control over notification rules such as user permissions and alert grouping, as well as attention towards resource usage since Redgate Monitor can be resource-intensive."
"Regarding pricing, setup cost, and licensing, I must say I don't favor the subscription model, and the price is somewhat higher."
 

Pricing and Cost Advice

"The solution is expensive."
"Nagios Core is an open source solution, and there are no licensing fees."
"The Nagios Core (PNP4Nagios + Core) is free and can be setup by Netadmin within a few hours. The only additional cost is the cloud server."
"We are using the free version."
"It's free."
"Nagios Core is free to use."
"We are using the free version of Nagios Core."
"We are using the open-source, unpaid version."
