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.

IT Infrastructure & Cloud Security Manager at Thux
Has ensured compliance by centralizing log data and supporting secure connections
We currently do not use that feature. We currently have just an open-source release, not a premium release. My boss has indicated that he wants to buy a premium syslog-ng version next month. I think we can use other features of this tool in the future. In syslog-ng, I think a GUI would be beneficial. I am unsure if the premium module has a GUI to administer it.

Quotes from Members

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

Pros

"We integrate our application logs. It is great to be able to tie our metrics and our traces together."
"The ease of correcting these dashboards and widgets when needed is amazing."
"Datadog infrastructure monitoring has helped us identify health issues with our virtual machines, such as high load, CPU, and disk usage, as well as monitoring uptime and alerting when Kubernetes containers have a bad time staying up."
"I find the greatest feature is being able to search across logs from various microservices."
"Because of our client focus, it is easy for us to sell. This is because it is easy to use and easy to set up."
"The monitoring functionality, in general, and tagging infrastructure are great."
"Sometimes it's more user friendly for development teams. There are some parts of Datadog that are more understandable for development teams. For example, the APM in Datadog works more manually and works like the tools in New Relic or Grafana, or Elastic. It is easier to understand for software development teams."
"The most valuable aspects of the product include the APM and profiler."
"Syslog-ng has a separate config file in addition to the core configuration."
"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 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."
"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."
"We chose syslog-ng because it is easy to install, easy to maintain, easy to update, and due to the fact that all data arrive in raw format, we can manipulate it as we want."
"What I appreciate most about syslog-ng is its configuration; its C-style config is much easier to understand, read, and write than other popular solutions such as syslog or rsyslog."
"The ability to extract and store the logs is the most valuable feature of syslog-ng."
 

Cons

"Additional metrics should be included."
"The monitors need improvement."
"We need more visibility into the error tracking dashboard."
"Auto instrumentation on tracing has not been very easy to find in the documentation."
"We would love to see a % consumed and alert us if we are over budget before getting an overage charge 20 days into the month."
"We have recently had a number of issues with stability and delays on logging, monitoring, metric evaluation, and alerts."
"When it comes to storing the logs with Datadog, I'm not sure why it costs so much to store gigabytes or terabytes of information when it's a fraction of the cost to do so myself."
"The documentation could be improved regarding setting up the agent properly and debugging."
"There is room for improvement in terms of observability."
"The filtering has room for improvement."
"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."
"In syslog-ng, I think a GUI would be beneficial. I am unsure if the premium module has a GUI to administer it."
"There is always the potential for additional integration and protocol extensions."
"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."
 

Pricing and Cost Advice

"If you do your homework, you'll find that if you're really concerned with cost, it's good."
"My advice is to really keep an eye on your overage costs, as they can spiral really fast."
"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."
"It didn't scale well from the cost perspective. We had a custom package deal."
"They prefer monthly subscriptions."
"Licensing is based on the retention period of logs and metrics."
"The tool is open-source."
"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."
