Assistant Director at a consultancy with 10,001+ employees
Enterprise-level monitoring facilitates global observability and seamless script creation with intuitive tools
SmartBear, as a vendor, is focusing more on API management and testing rather than monitoring. AlertSite could benefit from more future-focused innovation, especially with competencies in generative AI. Additionally, support from AlertSite is not at an enterprise level since it is not offered 24/7. Outside of critical platform issues, there's no continuous support available.

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.

Quotes from Members

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

Pros

"This solution has numerous advantages. It's extremely simple to configure. Either digital monitors or single-URL monitors are simple to configure and build."
"If there are any issues, it triggers an alert within 30 seconds. When it triggers the alert, we go ahead and check it immediately. The alert is triggered on a real-time basis."
"This solution has numerous advantages; it's extremely simple to configure, and either digital monitors or single-URL monitors are simple to configure and build."
"My company went with AlertSite because as a tool, it's fast, easy to maintain, and provides great support."
"The return on investment of this solution is well witnessed in our organization because of the integration and various capabilities that it offers to interact with the upstream or downstream systems."
"There are custom reports available along with the inbuilt reports."
"The alerting capabilities of AlertSite were really helpful."
"If there are any issues, it triggers an alert within 30 seconds."
"The most valuable features are the dashboards and the reporting."
"Straightforward to integrate and automate."
"It has drastically reduced the amount of time we spend on debugging issues and tracking down the root causes of incidents."
"Overall, it has improved operational efficiency and reduced downtime by enabling quicker responses during incidents."
"Datadog's learning platform is second to none."
"Monitors have also been very valuable when setting up our on-call processes. It makes it easy to set up and adjust alerting to keep our teams aware of anything going wrong."
"Each component complements the other, creating a cohesive system where data, logs, and metrics are seamlessly integrated."
"I don't have to worry about upgrades with the AWS version."
 

Cons

"I would like the ability to get more data points with regard to some of the unique requirements that we have."
"What needs improvement in AlertSite is the documentation, particularly the lack of documentation."
"I could use a few changes to the user interface."
"Additionally, support from AlertSite is not at an enterprise level since it is not offered 24/7."
"AlertSite sometimes triggers false alerts or fake alerts, which needs to be rectified. When we see an alert and go ahead and run certain tests on it, the test always passes. However, on the main screen, it shows up as critical. Therefore, the false alert needs to be fixed."
"In terms of support, it is all based on the cost of the subscription that our company purchased, but it wasn't great, and it could've been much better."
"It is not compatible with all of the product platforms that we use."
"AlertSite requires improvements related to security, even at the enterprise level."
"We need more integration functionality, including certain metrics integration."
"In terms of UI, everything is very small, which makes it quite difficult to navigate at times."
"Datadog's roadmap can be a bit unpredictable at times."
"Datadog could improve the flexibility with AI and ML concepts."
"The product could do better with its notifications."
"The FinOps needs improvement."
"Datadog does not have the feature where you can monitor external websites or check the SSL secure for websites."
"The solution should provide alerts for cloud outages that would allow us to report potential service impacts directly to applications or on the dashboard."
 

Pricing and Cost Advice

"We purchased the license once and had the option of selecting the number of user licenses."
"My company pays to use AlertSite, but I'm unsure of the exact costs because it depends on how many monitors you have."
"The cost is high."
"They prefer monthly subscriptions."
"The solution's pricing depends on project volume."
"The pricing came up a bit compared to their competitors. It is not that the price has risen, but that the competitors have gone down. They keep adding more features that I would have expected to be baked in at a more nominal price. I have been increasingly dissatisfied with the pricing, but not enough to jump ship."
"Pricing is somewhat affordable compared to other solutions but in order to really lower the costs of other products you need to plan very carefully your resources usage, otherwise, it can get expensive real quick."
"Licensing is based on the retention period of logs and metrics."
"The price of Datadog is reasonable. Other solutions are more expensive, such as AppDynamics."
"The pricing and licensing through AWS Marketplace has been good. It would be nice if it was cheaper, but their pricing is reasonable for what it is. Sometimes, for their newer features, they charge as if it's fully fleshed out, even though it is a newer feature and it may have less stuff than their other items."
"It is easy to run up a large bill, so become familiar with the cost of each piece of your bill and use the metrics they supply to estimate and monitor your bill."
