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.

Comprehensive monitoring has improved performance, capacity planning, and multi-source log analysis
VMware Aria Operations for Logs would be used to completely monitor the health of your environment. Second is to understand your existing capacity and forecast your capacity for the next year or so. Third would be on performance management, understanding how the environment is performing, and what has to be done to optimize it. We use VMware Aria Operations for Logs for these purposes. We also use VMware Aria Operations for Logs to monitor non-VMware components as well. VMware Aria Operations for Logs is now part of a bigger suite with several modules added. You have an option to collect logs from various sources and then you can do some sorts of analytics from it as well. All of this can be done with VMware Aria Operations for Logs.

Quotes from Members

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

Pros

"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."
"Syslog-ng has a separate config file in addition to the core configuration."
"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."
"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."
"The ability to extract and store the logs is the most valuable feature of syslog-ng."
"The events are notably more descriptive, aiding in security and event analysis. We've also integrated Sky Collector, providing valuable insights and solutions for troubleshooting."
"The solution's simplicity, flexibility, and extensibility are valuable features as we can integrate everything in vRealize."
"The most valuable feature is server virtualization. It's been very useful."
"The ability to narrow into a specific time to filter heavy hitters and anomalies is extremely valuable."
"vRealize Log Insight has been running without any issues."
"The most valuable features are log centralization and long-term retention for logs."
"The virtualization solution supports data center virtualization, network and security."
"It is a very useful tool if you have a VMware environment."
 

Cons

"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 room for improvement in terms of observability."
"There is always the potential for additional integration and protocol extensions."
"The product is really expensive compared to other products in the market."
"The dashboard needs to be improved because this is what I need to monitor my infrastructure."
"Customer service and support have declined. Six months ago, I would have rated it as an eight or nine. Currently, it feels more like a four, five, or six."
"The solution should be more user-friendly. The user interface and dashboard could be simplified."
"Log Insight should be better at dealing with audits and security logs. We use another product called QRadar for that."
"Documentation is lacking, including some guide as to how to use the expressions. It is not clear how to look for a log, for example. Some examples in the documentation might be helpful. I think that VMware had good documentation, but it's no longer hosted. The documentation is not as easy to understand as it was before."
"It needs better integration with third-party analytics tools."
"Log retention should have more options for user control."
 

Pricing and Cost Advice

"Syslog-ng is open-source."
"Syslog-ng is a free open-source solution."
"I am not sure what the exact cost is. However, I believe the vRealize suite costs $2,500.00 per year."
"Pricing is good because it is part of the suite package. It comes in a bundle for us."
"I think it is a reasonably priced product."
"The license cost for any other monitoring tool is too high compared to this product."
"I rate the product's price a six on a scale of one to ten, where one is cheap, and ten is expensive."
"The product's price is reasonable, but when it comes to SQL licensing, it's a bit expensive."
"Pricing could always be lower. If it were free, I would be more satisfied."
"It is not cheap. But it is worth it."
