Transforms logs for real-time insights and seamless reporting
Logstash is used for transforming logs, and you can use many plugins in Logstash. Logstash works with configuration files that contain three main parts: an input part, a filter part, and an output part. In the input part, we can take logs from many sources such as Beats, files, or Kafka. The filter part is used to filter the logs that are shipped from Beats. From my understanding and experience with Logstash, it is usually used for processing logic, meaning I can control what fields should be transferred to Elastic and what fields shouldn't be transferred. This is the main function I use Logstash for. Elastic is a famous open-source searching engine that helps operation teams speed up the investigation process and provides real-time insights for performance reporting.

Helps us detect cyber threats quickly and integrate multiple feeds effectively
Overall, the product is good, but when it comes to some infrastructure issues, we have to dig into more logs. There is no straightforward indication of an issue. Health check kind of dashboards are not available. More AI would help us, and more optimization, since security products run more queries. The AI module could suggest solutions, optimizing queries or workload balancing. If the product itself advises on running queries during peak times, it would be similar to what ChatGPT currently offers. We see quite a few issues on stability. Even last week, we faced something, and identifying bottlenecks is not easy. We need more SMEs, and there is no mechanism to tell us about indexer or search head issues. Self-monitoring dashboards could be beneficial. The technical support still requires more improvement. Often, primary support takes a lot of time and forwards most solutions to the engineering side. The primary support team has very limited knowledge to provide.

Quotes from Members

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

Pros

"Everything aligns well with improving our organization."
"Logstash has numerous plugins for inputs and outputs, allowing it to work well in environments that do not contain other Elastic components."
"We have three or four Logstash servers for high availability."
"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."
"I can collect logs from various data sources, including hardware."
"The functionality of Logstash is quite easy to implement and the plugin ecosystem of Logstash is great, with plugins for shell script monitoring and SQL monitoring working well with the tool."
"We are much faster finding and addressing issues with Splunk."
"I would definitely recommend using Splunk."
"I have found the installation can be of medium difficulty to very complex depending on the use case."
"Alerts when a server is malfunctioning, monitors external attacks, and takes action to stop spreading viruses."
"The product is good, it satisfies our customers."
"The reporting aspect is good and it does what I need it to do."
"Splunk Enterprise Security helped us with faster detection of threats."
"It is a very well-organized solution, more user-friendly than ArcSight and QRadar, where I can search and do whatever I need in terms of dashboards, reports, etc., making it the best tool if you have a complex environment or if data ingestion is too huge."
 

Cons

"The product needs to improve its compatibility."
"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."
"There can be a UI to implement with Logstash. Currently, I have to work with config files and everything."
"Elastic does not provide proper support for Logstash worldwide, and I rate their technical support as one out of ten."
"The only downside is the pricing."
"It is very complicated to write your own correlation rules without the help of Splunk support."
"Its user interface for everything other than the charts can be improved. Some parts of it can be simplified a bit, such as when importing documents that have the network traffic. When you're going through the information about the network traffic, you have to have the expertise, but even if a program is supposed to be for IT support, it is good to make it user-friendly because it gets easier to train people. When something goes wrong, the more difficult a program is in terms of UI, the harder it is to fix the issue."
"The GUI can be improved. Splunk has always suffered from having a kind of goofy UI, it needs some updating."
"When you get into large amounts of data, Splunk can get pretty slow. This is the same on-premise or AWS, it doesn't matter. The way that they handle large data sets could be improved."
"The biggest thing with Splunk is making sure that the documentation is maintained."
"It would be nice if Splunk provided a little more documentation and instructions on how to upload. The steps are short, but sometimes it's not so intuitive."
"Splunk's ability to analyze malicious activities scores an 8 out of 10, but there's room for improvement. By analyzing emerging patterns, Splunk could identify and predict potential threats more effectively."
 

Pricing and Cost Advice

Information not available
"The subscription is monthly."
"Splunk's cost is very high. They need to review the pricing. They have to go back and totally readdress the market."
"Splunk can be expensive, as its licensing is based on the daily data ingestion volume."
"I think that most of the log analytics solutions are expensive and I'm not sure if it's worth it."
"I am fine with the licensing, but in terms of the cost, it is expensive for the data that we have. We have an open discussion with our account rep about this."
"The pricing is based on the volume of data fed into it, which can lead to substantial costs. This pricing model is complex and unpredictable, making cost management difficult."
"We have had a reduction in the time it takes to resolve issues and correlate what has failed."
"The tool's pricing model is great. You can choose between workloads or volume."
