Points out the relevant problems in the enterprise and it's easy to understand
The most valuable aspect of this solution is the integration with their other systems. It's easy to understand and it points out the relevant problems in the enterprise I would like for it to have automated updates, the way the product updates itself should be all automated, as opposed to what it…

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

"Browsermetrix, which is real-user monitoring via JS injection and linked back to TTW via cookie. It allows us to see the experience of every user hitting our sites and analyze performance by region, browser, etc."
"As an Administrator, before we bought this AppInternals, I didn't have visibility on why items were slow or why an application was not running. This gives us the ability to see what's going on. The application is load balancing. We can now see if its own server has issues or just one specific server has issues."
"We just control on the backend of AppInternals what we want to instrument and what we don't want to instrument."
"Clicks to root cause - fast & easy to diagnose and deep-dive"
"I like it that one can match IPs with the application name."
"The product is very useful to find problems in middleware for the application servers, especially agent instrumentation and management is user friendly."
"The capability of analysing each individual transaction captured to a very low level detail (method call/line of code)."
"Transaction Tracing is the most useful. Being able to have the transaction stitched together so we can see where the problem is has proven invaluable."
"Being able to filter requests by latency is invaluable, as it provides immediate insight into which endpoints require further analysis and optimization."
"The ingestion points are unlimited and support customization. We haven't had anything yet that we haven't been able to integrate with it."
"By moving to Datadog, we did not need to manage our own monitoring infrastructure anymore."
"I don't have to worry about upgrades with the AWS version."
"Datadog has impacted my organization positively as this is our main observability tool when it comes to monitoring services, traces, and all resources within key services."
"Real user monitoring has made triaging any possible bugs our users might face a lot easier."
"The initial setup is very straightforward."
"We have been impressed with the uptime and clean and light resource usage of the agents."
 

Cons

"It would be great if the solution could offer fixed bundles and more features."
"The technical support is not very good and should be improved."
"I would like for it to have automated updates, the way the product updates itself should be all automated, as opposed to what it is now."
"We'd like to be able to find out performance problems on application class and methods."
"The recording mechanism for synthetic transactions could be improved as well."
"We have put in a request as an enhancement that we would like to search for items. If we're searching for a URL and we want to know was it a get or was it a post."
"The admin dashboard could be easier as it takes a little bit of time to get used to it."
"Support for PHP, DB and other applications need to be supported."
"The solution should provide alerts for cloud outages."
"There should be a clearer view of the expenses."
"I would appreciate seeing it as an app or mobile app for quicker issue tracking."
"I rate Datadog an eight out of ten because the expense of using it keeps it from being a nine or ten."
"The ability to find what you are looking for when starting out could be improved."
"I believe Datadog could be improved because sometimes it's not the most user-friendly, and when monitors have a new metric or a service that no longer needs to be monitored, it remains in the system."
"The query performance could be improved, particularly when handling large datasets, as slower response times can hinder efficiency."
"The product could be improved by providing remote control to agents, enabling them to execute automation and collections without requiring another automation tool or integration."
 

Pricing and Cost Advice

"The licensing model for v9 is better where it is an individual license per server, while v10 licenses are per JVM/ .NET and server instance. The latter model appears to be the model that other APM vendors are using."
"The licensing model is expensive compared to its competitors, but the service it gives to your business, and the data quality, means that it's worth it."
"The solution's pricing depends on project volume."
"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 didn't scale well from the cost perspective. We had a custom package deal."
"Licensing is based on the retention period of logs and metrics."
"This solution is budget friendly."
"It costs the same amount it would if we were hosting it ourselves, so we are incredibly happy with the cost."
"The cost is high and this can be justified if the scale of the environment is big."
"Pricing seemed easy until the bill came in and some things were not accounted for."
