Featured Reviews

Balamurali P - PeerSpot reviewer
Advanced query capabilities enhance monitoring effectiveness
Elastic Stack should be more simplified with ready-to-use widgets. Also, incorporating AI capabilities is essential as monitoring and observability tools are now adding AI features. Ideally, it should evolve into a full-stack observability tool, similar to AppDynamics or DynaTrace, which offers a solution that includes ISP provider, API monitoring, and infrastructure monitoring.
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.

Quotes from Members

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

Pros

"Prior to the latest updates, data lake management was a standout feature. The hybrid capability for on-premise and cloud integration was also crucial. Now, with Elastic Defense, the agent simplifies security monitoring, making it a key asset."
"The tool is huge, and it performs brilliantly. I tested it for malware, and within two weeks of launching, the product alerted me about a network intrusion. This was a tough test for it, but it performed admirably. The alerting system is excellent, and searching through logs is incredibly efficient. What's impressive is that all three products or options are integrated into one solution. This means I don't need separate logging, monitoring, or antivirus solutions."
"It is a very scalable solution...I didn't face any problem with this scalability part of the solution since we only have a few pieces of equipment in our company."
"The biggest strength of Elastic Stack is its brilliant archiving capabilities."
"The centralized logging capabilities of Elastic Stack have helped me streamline my logging processes significantly because there are many open-source tools available, such as Filebeat and Logstash, to collect the logs."
"The tool's most powerful aspect is its search engine capability. It's a highly effective and powerful solution for searching. We use it in professional and student projects at universities, and it delivers promising results."
"The detection rules in Elastic Stack are the most valuable feature. The search capabilities are excellent and fast. As we collect logs from workstations and devices, the detection rules run on top of the logs and detect any suspicious activity, raising alerts accordingly. Integration with Elastic Stack depends on the specific integration. Elastic provides some bridging integrations that make it easy, but require custom integration. Most integrations are simple, but customization can be challenging because we need to do some parsing. There's something called Elastic Common Schema, and we need to parse the source logs to match this schema, which can be a bit challenging."
"The scripting model in Elastic Stack allows me to query logs and then put the data into Grafana."
"UDP is a fast and lightweight protocol, perfect for sending large volumes of logs with minimal overhead."
"Graylog is valuable because it bridges technical knowledge to non-technical teams, presenting complex backend processes in a simple timeline."
"One of the most valuable features is that you are able to do a very detailed search through the log messages in the overview."
"It is used as a log manager/SIEM. It provides visibility into the infrastructure and security related events."
"The build is stable and requires little maintenance, even compared to some extremely expensive products."
"We're using the Community edition, but I know that it has really good dashboarding and alerts."
"Storing logs in Elasticsearch means log retrieval is extremely fast, and full text search is available by default."
"The ability to write custom alerts is key to information security and compliance."
 

Cons

"Elastic Stack should work on their dashboards and integration process."
"Support could be improved. The error code is not helpful. We have to ask for it or pass it on to community forums."
"The main issue related to Elastic Stack is in the area of its licensing."
"It should facilitate easier manual integration."
"It lacks a clear NDR (Network Detection and Response) feature. If Elastic could enhance this aspect, it would significantly boost its capabilities."
"When people try to move the data from another source to Elastic Stack for visualization, they face challenges when connecting to Elastic Stack from such different sources."
"The stability of the solution is rated as three or four out of ten as we frequently encounter issues."
"Elastic Stack's search capabilities can be challenging, especially when searching for precise data from past years, such as two or ten years ago. Its indexing performance for exact data retrieval may decrease as the data volume grows. Therefore, I believe there is room for improvement in the product's search functionality. It needs to improve its pricing as well."
"Its scalability gets complicated when we have to update or edit multiple nodes."
"The biggest problem is the collector application, as we wanted to avoid using Graylog Collector Sidecar due to its architecture."
"More customization is always useful."
"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."
"Since container orchestration systems are popular and Graylog fits the niche well, perhaps they could officially support running in docker containers on Kubernetes as a StatefulSet as a use case. That way, the declarative nature of Kubernetes config files would document their best case deployment scenario-"
"Lacks sufficient documentation."
"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."
"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."
 

Pricing and Cost Advice

"Ultimately, the pricing depends upon the capacity planning that the enterprise architect does."
"The product is expensive."
"The pricing is reasonable."
"If I compare Elastic Stack to the other products in the market, I would say that the tool is available at a competitive price."
"I used the open-source version of Elastic Stack, because of which I did not have to pay anything."
"I rate the solution's pricing a six out of ten."
"We are using the open-source community version of the product."
"It depends on the specifics, but generally, Elastic is economical for certain use cases."
"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."
"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."
"We are using the free version of the product. However, the paid version is expensive."
"Having paid official support is wise for projects."
"I use the free version of Graylog."
"We're using the Community edition."
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"It's an open-source solution that can be used free of charge."
