Featured Reviews

Ivan Kokalovic - PeerSpot reviewer
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.
Vinay Patel D N - PeerSpot reviewer
Effective with good log analytics but needs better rule correlation
The correlation rules and log mapping are not as mature compared to other SIM tools like Splunk. Sometimes logs will not fetch, and there are issues if the log volume exceeds a threshold. Not every tool is integrated with Sumo Logic. The response time for their support could be better, and it is not very user-friendly.

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."
"The build is stable and requires little maintenance, even compared to some extremely expensive products."
"It has data adapters and lookup tables that utilize HTTP calls to APIs."
"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."
"We're using the Community edition, but I know that it has really good dashboarding and alerts."
"The ability to write custom alerts is key to information security and compliance."
"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."
"UDP is a fast and lightweight protocol, perfect for sending large volumes of logs with minimal overhead."
"Scalability has been good for our needs. We haven't run into any scaling issues in regards to size so far."
"Sumo Logic Security is a good solution for searching the logs and identifying the issues."
"We use it to ingest Windows domain controller logs. We use this to monitor if anyone is placed in particular administration groups that potentially shouldn't be. It helps us keep track of people."
"Sumo Logic is an easy solution to use. You can set it up very quickly, and it includes a lot of training videos."
"The most valuable features of Sumo Logic Security are the rules, use cases, and ease of use. Additionally, the integration is straightforward and good GUI."
"The features I found valuable with the Sumo Logic Security solution are the search option and the ability to customize the search for the information in the logs."
"The Log Analytics platform is the most effective. If we cannot find the data in other tools, like email security or NDR, we can fetch those logs in the Log Analytics platform of Sumo Logic."
"It helps a lot because we can troubleshoot issues pretty easily."
 

Cons

"I hope to see improvements in Graylog for more interactivity, user-friendliness, and creating alerts. The initial setup is complex."
"More complex visualizations and the ability to execute custom Elasticsearch queries would be great."
"With technical support, you are on your own without an enterprise license."
"The infrastructure cost is the main issue. I like the rest. If the infrastructure costs could be lower, it would be fantastic."
"The biggest problem is the collector application, as we wanted to avoid using Graylog Collector Sidecar due to its architecture."
"Graylog can improve the index rotation as it's quite a complex solution."
"There should be some user groups and an auto sign-in feature.​"
"It would be great if Graylog could provide a better Python package in order to make it easier to use for the Python community."
"We would like the ability to drill down into a dashboard and get into deeper levels."
"The solution should improve its UI."
"The initial setup is the most stressful, like learning how to use it."
"We would like to have some type of predefined setup for the logs, making the setup easier by default."
"There needs to be improvement on imported data which can be used within Sumo Logic to do more advanced queries."
"If you look at some of the other offerings right now that are available in the market, they do offer APM as well as the product they're offering. I believe Sumo Logic is not there yet. So that's something which I would love to see."
"I would like to see improvement in the user experience when configuring things, ingesting logs, and creating ports."
"It would be nice to have an improved ability to scroll through logs within a time frame. Right now, we can search for specific errors. However, if we want to look for "before and after" within a specific time frame, it's not easy using the tool. This would be an improvement."
 

Pricing and Cost Advice

"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."
"We're using the Community edition."
"We are using the free version of the product. However, the paid version is expensive."
"I use the free version of Graylog."
"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.​​"
"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."
"The AWS Marketplace pricing is fairly reasonable for what it does. I wouldn't call it expensive, but I wouldn't call it cheap. It is pretty good."
"Pricing has been cheaper than some of the competing tools, like Splunk."
"The pricing is good. It's not an issue for us."
"If we went to ELK Stack, which is open source, it would have been less costly, but it would have required more development from our side."
"The price scaling comes in a bit expensive."
"The license pricing model is based on the events that are processed through the solution."
"The product is costly."
"The only limit to the scalability of the product for us is how much we are willing to pay."
