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.

The solution is a consistent logging platform that provides excellent query mechanisms

We can query a lot of data points and build dashboards. The vendor is good at adjusting their models. Most companies want us to forecast our yearly use and pay it upfront on day one. With Logz.io, we commit to use 14 TB in a year. However, they measure us every month and give us a monthly bill. Depending on our monthly usage, we pay for 14 TB divided by 12 months or a little extra. It's a little bit more like AWS. Other solutions do not do it. They want their money upfront. We really like the dashboards. We have 36 sub-accounts. Each sub-account is an app, and we could put restrictions on that app. Previously, there were capacity restrictions on the sub-accounts. If we have a sub-account of 1 TB and use only 100 GB, we waste 900 GB that day. We could not share it between sub-accounts. Now, they provide an overhead volume. We do a reserve, and any sub-account could use anything over the reserve. It utilizes our footprint better.

Quotes from Members

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

Pros

"Message forwarding through the in-built module."

"It is used as a log manager/SIEM. It provides visibility into the infrastructure and security related events."

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

"We run a containerized microservices environment. Being able to set up streams and search for errors and anomalies across hundreds of containers is why a log aggregation platform like Graylog is valuable to us."

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

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

"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."

"The product is scalable. The solution is stable."

More Graylog pros

"InsightOne is the main reason why we use LogMeIn. This is mostly because of log data that we are pushing tools and logs in general."

"The query mechanism for response codes and application health is valuable."

"We use the tool to track the dev and production environment."

"The visualizations in Kibana are the most valuable feature. It's much more convenient to have a visualization of logs. We can see status really clearly and very fast, with just a couple of clicks."

"The tool is simple to setup where it is just plug and play. The tool is reliable and we never had any performance issues."

"The other nice thing about Logz.io is their team. When it comes to onboarding, their support is incredibly proactive. They bring the brand experience from a customer services perspective because their team is always there to help you refine filters and tweak dashboards. That is really a useful thing to have. Their engagement is really supportive."

"It is massively useful and great for testing. We can just go, find logs, and attach them easily. It has a very quick lookup. Whereas, before we would have to go, dig around, and find the server that the logs were connected to, then go to the server, download the log, and attach it. Now, we can just go straight to this solution, type in the log ID and server ID, and obtain the information that we want."

"We use the product for log collection and monitoring."

Cons

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

"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."

"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."

"The biggest problem is the collector application, as we wanted to avoid using Graylog Collector Sidecar due to its architecture."

"Lacks sufficient documentation."

"More customization is always useful."

More Graylog cons

"Capacity planning could be a little bit of a struggle."

"The solution needs to expand its access control and make it accessible through API."

"The price can be cheaper and they should have better monitoring."

"The product needs improvement from a filtering perspective."

"When it comes to reducing our troubleshooting time, it depends. When there are no bugs in Logz.io, it reduces troubleshooting by 5 to 10 percent. When there are bugs, it increases our troubleshooting time by 200 percent or more."

"I would like granularity on alerting so we can get tentative alerts and major alerts, then break it down between the two."

"I would like them to improve how they manage releases. Some of our integrations integrate specifically with set versions. Logz.io occasionally releases an update that might break that integration. On one occasion, we found out a little bit too late, then we had to roll it back."

"The solution needs to improve its data retention. It should be greater than seven days. The product needs to improve its documentation as well."

Pricing and Cost Advice

"We're using the Community edition."

"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."

"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."

"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."

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

"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."

More Graylog pricing and cost advice

"At the time it was set up, we thought Logz.io was very reasonable for what we were getting in terms of how much time and hosting costs it was saving us, because you don't have to run the servers for it anymore."

"You pay for what you need, and that is a good model. They are also quite happy to talk to you about your uses and your use case. They will even go as far as suggesting things that you don't need to do in order to save you money. At one point, I was quite surprised at how cheap it could be if we wanted it to be or how much they would help us manage our costs."

"The product is a little expensive."

"The product's pricing is cheaper than other solutions."

"The tool is an open source product."
