Customization enables tailored monitoring and alerting across departments
The possibility to customize it has been quite useful. Whatever the other departments want to dream up, we implement. Whatever they want to monitor, the granularity of it, the changes in the threshold, and the anomalies that they want reported all require some development. So far, every single request has been fulfilled.

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

"We use AppDynamics and Elastic. The reason why we're using Elastic APM is because of the license count. It's very favorable compared to AppDynamics. It's inexpensive; it's economical."
"The architecture and system's stability are simple."
"For full stack observability, Elastic is the best tool compared with any other tool ."
"Good design and easy to use once implemented."
"The most valued feature of Elastic is its log analytics capabilities."
"Its diverse set of features available on the cloud is of significant importance."
"Elastic provides built-in features for queries and report generation. It's a very good tool for monitoring integration capabilities."
"Elastic APM has plenty of features, such as the Elastic server for Kibana and many additional plugins. It's a comprehensive tool when used as a logging platform."
"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 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."
"The ability to extract and store the logs is the most valuable feature of syslog-ng."
"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."
 

Cons

"Elastic Observability needs to have better standardization, logging, and schema."
"One example is the inability to monitor very old databases with the newest version."
"I am familiar with Azure Monitor, which I find more user-friendly compared to Elastic, which is a very technical tool."
"In the future, Elastic APM needs a portfolio iTool. They can provide an easy way to develop the custom UI for Kibana."
"The solution would be better if it was capable of more automation, especially in a monitoring capacity or for the response to abnormalities."
"The interface could be improved."
"Elastic Observability needs to improve the retrieval of logs and metrics from all the instances."
"There's a steep learning curve if you've never used this solution before."
"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."
"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."
"There is room for improvement in terms of observability."
"The filtering has room for improvement."
 

Pricing and Cost Advice

"Pricing is one of those situations where the more you use it, the more you pay."
"Elastic Observability's pricing could be better for small-scale users."
"The product’s pricing needs improvement."
"Since we are a huge company, Elastic Observability is an affordable solution for us."
"Users have to pay for some features, like the alerts on different channels, because they are unavailable in different source versions."
"Elastic Observability is cheaper than other similar solutions, such as Dynatrace. Its license calculation is based on various factors like data volume and physical infrastructure, particularly related to RAM capacity."
"We will buy a premium license after POC."
"One needs to pay for the licenses, and it is an annual subscription model right now."
"Syslog-ng is open-source."
"Syslog-ng is a free open-source solution."
