Cost-effective logging solution with room for search and interface improvement
Our primary use case is logging for everything within the company. We have a custom LogShipper, and for whatever deployments we have, we add the LogShipper into our containers, apply customer configurations to parse log files, and send desired fields to ChaosSearch. We then review logs on…

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

"ChaosSearch is considered a cheaper alternative to Elastic."
"ChaosSearch is considered a cheaper alternative to Elastic."
"Syslog-ng has a separate config file in addition to the core configuration."
"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."
"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."
"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

"During my time at Klarna, I didn't see any improvements from using ChaosSearch."
"The user interface could be more intuitive and requires 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."
"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."
"There is room for improvement in terms of observability."
"There is always the potential for additional integration and protocol extensions."
"The filtering has room for improvement."
"In syslog-ng, I think a GUI would be beneficial. I am unsure if the premium module has a GUI to administer it."
