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

"Allowing us to set up alerts and integrate with platforms we already use, such as Slack and OpsGenie to alert users of these errors proactively, is also a very useful feature."

"We're using the Community edition, but I know that it has really good dashboarding and alerts."

"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."

"Open source and user friendly."

"What I like about Graylog is that it's real-time and you have access to the raw data. So, you ingest it, and you have access to every message and every data item you ingest. You can then build analytics on top of that. You can look at the raw data, and you can do some volumetric estimations, such as how big traffic you have, how many messages of data of a type you have, etc."

"UDP is a fast and lightweight protocol, perfect for sending large volumes of logs with minimal overhead."

"Storing logs in Elasticsearch means log retrieval is extremely fast, and full text search is available by default."

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

More Graylog Enterprise pros

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

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

Cons

"Over six months, I had two similar issues where searches were performed on field "messages". It exhausted all the memory of the ES node causing an ES crash and a Graylog halt."

"Elasticsearch recommendations for tuning could be better. Graylog doesn't have direct support for running the system inside of Kubernetes, so it can be challenging to fill in the gaps and set up containers in a way that is both performant and stable."

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

"More customization is always useful."

"Graylog needs to improve their authentication. Also, the fact that Graylog displays logs from the top down is just ridiculous."

"I would like to see a default dashboard widget that shows the topology of the clusters defined for the graylog install."

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

"I hope to see improvements in Graylog for more interactivity, user-friendliness, and creating alerts. The initial setup is complex."

More Graylog Enterprise cons

"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."

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

Pricing and Cost Advice

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

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

"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."

"I use the free version of Graylog."

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

"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."

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

"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."
