Facilitates backend service monitoring with efficient log retrieval and API flexibility

Graylog is valuable because it bridges technical knowledge to non-technical teams, presenting complex backend processes in a simple timeline. It boosts the knowledge of sales and customer support teams by allowing them to see the backend operations without needing to read the code. Its API is flexible for visualization, and its powerful search engine efficiently handles large volumes of log data. Moreover, its stability, fast search capabilities, and compatibility with languages like ANSI SQL enhance its utility in IT infrastructure.

A scalable and affordable tool for monitoring data centers

Five engineers are needed for the maintenance of the product. I would definitely recommend the solution to those planning to use it. To increase the rating for the product, Nagios should offer remote support and offer more customization in reporting while making it easy for the customers to use it. Overall, I rate the solution an eight out of ten.

Quotes from Members

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

Pros

"It has data adapters and lookup tables that utilize HTTP calls to APIs."

"Graylog is very handy."

"The Graylog features that have proven to be most beneficial for our data analysis in particular are that we tend to use it as a big data store, so we have the correlation rules that, if something matches under certain conditions, it raises an alarm."

"Message forwarding through the in-built module."

"The best feature of Graylog is the Elasticsearch integration. We can integrate and we can run filters, such as an event of interest, and those logs we can send to any SIEM tool or as an analytic. Additionally, there are clear and well-documented implementation instructions on their website to follow if needed."

"This had increased productivity for the dev and support teams, because we are directly notifying them."

"Graylog's search functionality, alerting functionality, user management, and dashboards are useful."

"Open source and user friendly."

More Graylog Enterprise pros

"The initial setup of Nagios Log Server was easy and straightforward."

"One of the most valuable features is the dashboard because the UI was effective and easy to use. The alert systems are good as well. We had no failovers and had high availability. We can search the queries fast as well in Nagios Log Server."

"A great feature of the solution involves its internal portal."

"The product is scalable."

Cons

"Lacks sufficient documentation."

"When it comes to configuring the processing pipeline, writing the rules can be very tedious, especially since the documentation isn't extensive on how the functions provided for these rules work."

"I would like to see some kind of visualization included in Graylog."

"More complex visualizations and the ability to execute custom Elasticsearch queries would be great."

"Dashboards, stream alerts and parsing could be improved."

"It would be great if Graylog could provide a better Python package in order to make it easier to use for the Python community."

"Its scalability gets complicated when we have to update or edit multiple nodes."

"I would like to see a date and time in the Graylog Grok patterns so that I can save time when searching for a log. I like how the streams and the search query work, but adding a date and time will allow me to pull out a log in a milli-second."

More Graylog Enterprise cons

"The customization and dashboards have shortcomings and need to be improved to make the tool look more presentable."

"As we are talking about a product which is open to the public, the pricing makes it challenging for us to profit off of its marketing."

"The configurations during initial setup could be improved. If they could be agentless, as in the case of the Ansible product, it would be better. I would like to be able to analyze the network bandwidth."

"The support could be better."

Pricing and Cost Advice

"You get a lot out-of-the-box with the non-enterprise version, so give it a try first."

"Graylog is a free open-source solution. The free version has a capacity limitation of 2 GB daily, if you want to go above this you have to purchase a license."

"If you want something that works and do not have the money for Splunk or QRadar, take Graylog."

"It's open source and free. They have a paid version, but we never looked into that because we never needed the features of the paid version."

"There is an open source version and an enterprise version. I wouldn't recommend the enterprise version, but as an open source solution, it is solid and works really well."

"We're using the Community edition."

"We are using the free version of the product. However, the paid version is expensive."

"Consider Enterprise support if you have atypical needs or setup requirements."

More Graylog Enterprise pricing and cost advice

"On a scale of one to ten, where one is expensive, and ten is cheap, I rate the pricing an eight or nine."

"We found the pricing to be quite affordable."

"For a single instance, the price is around $4,000."
