Room For Improvement

Datadog should enhance AI, improve customization, offer real-time insights, and optimize transparency for better user experience and performance.
Nagios XI's interface is outdated, lacks scalability, needs better cloud integration, APIs, automation, and improved documentation.
SolarWinds NPM users seek improvements in network discovery, interface, integration, resource usage, cloud support, security, and pricing adjustments.
It would be great to see stronger AI-driven anomaly detection and predictive analytics to help identify potential issues before they impact performance.

Setup Cost

Datadog offers flexible, usage-based pricing favored by SMEs, but enterprise users face complexity and potential high costs for new features.
Nagios XI provides cost-efficient enterprise-level monitoring with reasonable pricing, appreciated for its features and open-source options.

The setup cost for Datadog is more than $100.

Everybody wants the agent installed, but we only have so many dollars to spread across, so it's been difficult for me to prioritize who will benefit from Datadog at this time.

Featured Reviews

Dhroov Patel - PeerSpot reviewer
Site Reliability Engineer at Grainger
Has improved incident response with better root cause visibility and supports flexible on-call scheduling
Datadog needs to introduce more hard limits to cost. If we see a huge log spike, administrators should have more control over what happens to save costs. If a service starts logging extensively, I want the ability to automatically direct that log into the cheapest log bucket. This should be the case with many offerings. If we're seeing too much APM, we need to be aware of it and able to stop it rather than having administrators reach out to specific teams. Datadog has become significantly slower over the last year. They could improve performance at the risk of slowing down feature work. More resources need to go into Fleet Automation because we face many problems with things such as the Ansible role to install Datadog in non-containerized hosts. We mainly want to see performance improvements, less time spent looking at costs, the ability to trust that costs will stay reasonable, and an easier way to manage our agents. It is such a powerful tool with much potential on the horizon, but cost control, performance, and agent management need improvement. The main issues are with the administrative side rather than the actual application.
Emmanuel Appiah Boateng - PeerSpot reviewer
Network and Security Engineer at a educational organization with 1,001-5,000 employees
Simplifies setup and requires user interface enhancement
Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried. Typically, setting up a monitoring system on Linux involves cloning files from GitHub, building it, and installing many dependencies, but with Nagios XI, it wasn't like that. Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools.
Vivek Jaiswal - PeerSpot reviewer
Manager IT at a manufacturing company with 1,001-5,000 employees
Central monitoring has improved outage alerts and now needs smarter detection and modern dashboards
Regarding the automated network topology and mapping feature in SolarWinds NPM, I am not satisfied with it. For static monitoring, it is acceptable. However, if it is possible, I would need a feature in SolarWinds in the future for some kind of malfunctioning detection, such as malware attacks or that type of environment. We did not have any facility to detect that in SolarWinds. I think it would be better to incorporate those types of features. Regarding customization options in SolarWinds, the ability to customize the dashboard has room for improvement. The dashboard is quite old, and we need some improvement in it. Nowadays, we have multiple tools with AI-based monitoring and web-based dashboards. SolarWinds also has a web-based dashboard, but I think there is scope for improvement in the UI. There may be other areas I would like to improve in SolarWinds NPM.
