Kevin Palmer - PeerSpot reviewer
Useful log aggregation and management with helpful metrics aggregation
Datadog provides us value in three major ways: First, Datadog provides best-in-class functionality in many, if not all, of the products to which we subscribe (infrastructure, APM, log management, serverless, synthetics, real user monitoring, DB monitoring). In my experience with other tools that provide similar functionality, Datadog provides the largest feature set with the most flexibility and the best performance. Second, Datadog allows us to access all of those services in one place. Having to learn and manage only one tool for all of those purposes is a major benefit. Third, Datadog provides significant connectivity between those services so that we can view, summarize, organize, translate and correlate our data with maximum effect. Not needing to manually integrate them to draw lines between those pieces of information is a huge time savings for us.

It's a user-friendly open-source solution that can replace or augment a commercial product in some cases
I rate syslog-ng 10 out of 10. It's free and easy to use. It has built-in tools that help us index the various logs sent to it. It's a solid log product. If you're looking for a SIEM solution, syslog-ng will work as a stopgap measure at beginning of the project. It can also work as an injector for a true SIEM solution. You can send all the logs to syslog-ng and forward all the data to the SIEM solution after you've cleaned up the data and got the pertinent information. It's a good front end for a commercial SIEM solution, which becomes more expensive as you load more data into it. I would highly recommend syslog-ng for that use case. However, if you lack the expertise, you might need to go with a cloud-based SIEM instead. You need some in-house expertise or an outside consultant to manage it and set it up.

Quotes from Members

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

Pros

"The network map is crucial in identifying bottlenecks and determining what needs more attention."
"The feature I have found most valuable is when I can reuse existing monitors and alerts for new dashboards."
"I have found the logging and tracing features the most valuable."
"It has a high-level insight into the infrastructure model of the application and provides important detailed data on the host and metrics, which is the main concern of our customers."
"The ability to send notifications based on metadata from the monitor is helpful."
"This is definitely a good product and I would consider them one of the leaders within the application monitoring and cloud monitoring space."
"Going from viewing a metric to creating a monitor alerting on a metric is very easy."
"The best way it has helped us is by consolidating all our logs into a single place and making it easier to find errors."
"Syslog-ng has a separate config file in addition to the core configuration."
"Syslog-ng has built-in features that we can use to create alerts for a SIEM solution. It isn't a true SIEM solution, but it's sufficient for the time being."
"The ability to extract and store the logs is the most valuable feature of syslog-ng."
"For us, the most valuable feature is the use of compound search for searching logs at a specific time, by a specific user, or specific behavior."
"Syslog-ng provides easy access to all my logs. It helps me show managers and other clients precisely where an incident occurred. I also like it because you can integrate syslog-ng with multiple solutions to allow real-time monitoring."
 

Cons

"The logging could be improved in the future."
"Presently, the billing CSV reports provide insights into billing-related information yet are somewhat limited in functionality, typically offering reports with only three columns."
"It does not have the best interface."
"When the logs are too big, and Datadog splits them, the JSON format breaks and it is not so useful for us."
"The sheer amount of products that are included can be overwhelming."
"Network device and performance monitoring could be improved, as we've faced some limitations in this area."
"Billing should be more transparent."
"Sometimes it’s difficult to customize certain queries to find specific things, specifically with the logging solution."
"It's hard to find people who know how to use syslog-ng. I often find problems with configurations, and solutions aren't integrated correctly with syslog-ng. For example, there might be data with extra decimals, or the collector agents are incorrectly named. It isn't a problem with the solution; it's a lack of professionals."
"Syslog-ng has built-in features that we can use to create alerts for a SIEM solution. It isn't a true SIEM solution, but it's sufficient for the time being."
"The filtering has room for improvement."
"There is room for improvement in terms of observability."
"There is always the potential for additional integration and protocol extensions."
 

Pricing and Cost Advice

"If you do your homework, you'll find that if you're really concerned with cost, it's good."
"Pricing seemed easy until the bill came in and some things were not accounted for."
"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."
"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."
"At my last company, we did see ROI, specifically around response time. We could get to mission critical things that were down and losing revenue on immediately. So, the product paid itself back."
"It has a module-based pricing model."
"They prefer monthly subscriptions."
"It costs the same amount it would if we were hosting it ourselves, so we are incredibly happy with the cost."
"Syslog-ng is a free open-source solution."
"Syslog-ng is open-source."
