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.
Thanuja Karunarathne - PeerSpot reviewer
Engineer at Connex Information Technologies
Real-time monitoring and analytics are very easy and fast and very easy to use
The alerting and real-time analytics helped the security team. They are using a Hadoop database, so real-time monitoring and analytics are very easy and fast. Queries return results quickly and in very small time. It has full automation and automated SIEM responses. We are currently only testing Logsign, but in a few months, we plan to integrate our servers, routers, firewalls, and endpoints into our company's Logsign instance. Then, we can manage everything using Logsign.

Quotes from Members

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

Pros

"Our primary alerts, based on metrics and synthetic transactions, are the most used and relied upon for decreased MTTA/MTTR across all of our platforms. This is followed by deep log analysis that enables us to quickly and easily get to a preliminary root cause that someone on the infrastructure, platform or development teams can take and focus their attention on the precise target that Datadog revealed as the issue to be remediated."
"Datadog has allowed us to ensure that we can look at how our beta testers are using our new UIs and seeing where their frustration points are, which has been important to us."
"The server monitoring, service monitoring, and user session monitoring are extremely helpful, as they allow us to be alerted ahead of time of issues that users might experience."
"For us to have visibility into our app stack and the hardware we run has been highly beneficial."
"Datadog's seamless integration with Slack and PagerDuty helped us to receive alerts right to the most common notification methods we use (our mobile devices and Slack)."
"We've found it most useful for managing Rstudio Workbench, which has its own logs that would not be picked up via Cloudwatch."
"Datadog agents act as an integration to different services, providing easy access and management."
"The visibility into our network has allowed for quick diagnosis of failures, identification of underutilized or over-utilized resources, and allowed for cloud cost optimization opportunities."
"It has full automation and automated SIEM responses."
"Logsign provides sample logs within the product, allowing users to see how logs will appear before integration, which is a valuable feature for testing and understanding log formats."
"The most valuable features of Logsign SIEM are its cloud capabilities, alerting functionality, integration with Elastic Search, and configuration options."
 

Cons

"One of the improvement opportunities that we have identified in my project concerns how hard it is to manage an organizational structure when you have multiple things in one organization, and you want to provide some kind of isolation between them."
"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 only issue I face is when more than one person editing these dashboards simultaneously, one or the other person sometimes loses his/her work."
"The correlation between the logs and the metrics needs improvement as most cases, we might use another logging tool (that is cheaper in cost) which we then have to link together."
"Additional metrics should be included."
"Datadog does not have the feature where you can monitor external websites or check the SSL secure for websites."
"We would really like to see more from the Service Catalog."
"Datadog's roadmap can be a bit unpredictable at times."
"I hope they address the pricing model for Logsign Next-Gen SIEM, especially regarding regional variations. The pricing should not differ based on the country of operation as it can lead to dissatisfaction among customers. A fixed pricing structure would be more favorable for us. I would also suggest enhancing the GUI interface and adding features similar to xFi Exchange from IBM Pure. This would streamline operations and save time for analysts."
"Improvements needed in Logsign SIEM are providing specific security alerts that can be filtered and configured more effectively."
"AI and machine learning need to be developed. If they develop those features, I think everything will be fine."
 

Pricing and Cost Advice

"It has always scaled for us. Cost scales up too, but that is not necessarily a bad thing. It's reasonable for what they're providing."
"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."
"Sometimes it's very hard to project how much it will cost for the monthly subscription for the next month when you add certain features. Having better visibility of the cost would give a better experience."
"My advice is to really keep an eye on your overage costs, as they can spiral really fast."
"Licensing is based on the retention period of logs and metrics."
"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."
"This solution is budget friendly."
"The tool is open-source."
"Compared to other SIEMs, it has low pricing."
