"We can manage the entire system across the network and troubleshoot the pain points."
"Datadog has clear dashboards and good documentation."
"Straightforward to integrate and automate."
"It lets us react more quickly to things going wrong. Whereas before, it might have been 30 minutes to an hour before we noticed something going on, we will know within a minute or two if something is off, which will let us essentially get something back up and running faster for our customers, which is revenue."
"I really enjoy the RUM monitoring features of Datadog. It allows us to monitor user behavior in a way we couldn't before."
"It has scaled great. I haven't run into any problems anywhere that I've used it. They have handled everything that we have needed them to."
"The ease of correcting these dashboards and widgets when needed is amazing."
"The tools are powerful and intuitive to set up."
"We have been able to set very specific CPU and memory alerts, at the very base level, then we started to pull real business value, like 99th percentile response rates for our API calls."
"It's a monitoring agent. It's designed to do one thing. Its most valuable feature is its monitoring."
"The solution has a lot of plugins and scripts integrated with it."
"The Script Module in Nagios is really easy to use and is really cost efficient."
"The dashboard allows you to see what's going on in the overall system."
"Nagios XI helped me to draw the network and check for system failures."
"Nagios XI is stable."
"This is a very good solution and it is simple to use, for any company."
"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 Wi-Fi side needs improvement."
"In the past two years, there have been a couple of outages."
"I would love to see support for front-end and mobile applications. Right now, it is mostly all back-end stuff. Being able to do some integration with our front-end products would be awesome."
"We have asked technical support questions, and sometimes they don't get back to us right away. Or when they do, it is not the right answer."
"Datadog could have a better business analysis module."
"Datadog has a lot of features kind of cramped into one dashboard. It's quite hard to get around what feature does exactly what. There was a steep learning curve, trying to navigate through menus."
"The solution needs to integrate AI tools."
"As a new customer, the Datadog user interface is a bit daunting."
"We need more integration with security tools like Drata."
"The interface could be more user-friendly."
"The product does not have SAP monitoring."
"The technical support is variable - sometimes I get answers, but most of my tickets go unanswered."
"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 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."
"There's room for improvement in the visibility, and in the ability to extract information. Stuff like this should be more simple."
"I would like to see more customization in the network map because it is a bit tricky to use it."
"The product uses the backend as Perl and could be modified to a more lightweight solution like what's being offered by other vendors."
