Open-source accessibility and ease of implementation empower adaptable log management

As both a customer and an integrator, I think the best features in Logstash are that people prefer it because it is open to all, as it is an open-source version. The functionality of Logstash is quite easy to implement. I can say that the plugin ecosystem of Logstash is great. I have used some plugins for shell script monitoring and for SQL monitoring, and these are all working well with Logstash. The real-time processing capabilities of Logstash are also pretty fine with the tool. When I use the community edition, I have to do many things manually. If I am using enterprise Elastic, then that is taken care of by the Elastic native machine learning.

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

"I can collect logs from various data sources, including hardware."

"The transformation means we ship the logs in the way that we want them to be presented in Kibana, which is the main function we use Logstash for."

"Everything aligns well with improving our organization."

"We have three or four Logstash servers for high availability."

"Logstash has numerous plugins for inputs and outputs, allowing it to work well in environments that do not contain other Elastic components."

"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."

"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 has a separate config file in addition to the core configuration."

"The ability to extract and store the logs is the most valuable feature of syslog-ng."

Cons

"We still have a problem with importing the log system."

"The product needs to improve its compatibility."

"There can be a UI to implement with Logstash. Currently, I have to work with config files and everything."

"An enhancement we could implement is the ability to cluster Logstash to exist in more than one node."

"Almost all the research can be very bad. We still have a problem with importing the log system."

"Elastic does not provide proper support for Logstash worldwide, and I rate their technical support as one out of ten."

"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."

"The filtering has room for improvement."

"There is always the potential for additional integration and protocol extensions."

"There is room for improvement in terms of observability."

"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."
