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.

It consolidates all logs into one place and provides required features and functionalities

Every once in a while, our IBM cloud operational implementation gets behind. Sometimes, when we have a customer event, we do not get access to the latest logs for about 30 minutes, particularly for the sites that are heavily utilized. This is clearly not good. It is impossible to do RCA when you can't look at the logs that pertain to the time period in which the event occurred. It could be more of an operational problem than a feature problem. I don't have visibility about whether it is a LogDNA issue or just an operational issue.

Quotes from Members

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

Pros

"Everything stands out as valuable, including the fact that I can quantify and qualify the logs, create pipelines and process the logs in any way I like, and create charts or data maps."

"The build is stable and requires little maintenance, even compared to some extremely expensive products."

"The solution's most valuable feature is its new interface."

"Real-time UDP/GELF logging and full text-based searching."

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

"We have scaled from a single machine installation (a VM with a Graylog + ES + MongoDB) to (2 Graylog + 2 ES + 3 MongoDB). This was done smoothly with a minimal impact on logging."

"I am very proud of how very stable the solution is."

"One of the most valuable features is that you are able to do a very detailed search through the log messages in the overview."

More Graylog pros

"The solution aggregates all event streams, so that if there are any issues, it's all in the same interface."

"LogDNA consolidates all logs into one place, which is super valuable."

Cons

"We ran into problems with Elasticsearch throwing a circuit-breaking exception due to field data size being too large. It turned out that the heap size directly impacted this size in a high-throughput environment, causing unexplained instability in Graylog. We were able to troubleshoot on the Elasticsearch size, but we should have been able to reference some minimum requirements for Graylog to know that our settings weren't sufficient."

"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."

"More customization is always useful."

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

"Graylog could improve the process of creating rules. We have to create them manually by doing parses and applying them. Other SIEM solutions have basic rules and you can create and get more events of interest."

"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."

"Graylog can improve the index rotation as it's quite a complex solution."

More Graylog cons

"No ability to encapsulate a query or a filter, and communicate or share that among the team."

"Every once in a while, our IBM cloud operational implementation gets behind. Sometimes, when we have a customer event, we do not get access to the latest logs for about 30 minutes, particularly for the sites that are heavily utilized. This is clearly not good. It is impossible to RCA when you can't look at the logs that pertain to the time period in which the event occurred. It could be more of an operational problem than a feature problem. I don't have visibility about whether it is a LogDNA issue or just an operational issue."

Pricing and Cost Advice

"Having paid official support is wise for projects."

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

"I am using a community edition. I have not looked at the enterprise offering from Graylog."

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

"It's an open-source solution that can be used free of charge."

"We're using the Community edition."

"I use the free version of 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."
