"Graylog's search functionality, alerting functionality, user management, and dashboards are useful."
"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."
"This had increased productivity for the dev and support teams, because we are directly notifying them."
"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."
"I like the correlation and the alerting."
"UDP is a fast and lightweight protocol, perfect for sending large volumes of logs with minimal overhead."
"Message forwarding through the in-built module."
"We're using the Community edition, but I know that it has really good dashboarding and alerts."
"This is a straightforward solution, easy to configure."
"The feature that we use the most is the correlation search engine within ES."
"Recently, Splunk upgraded to version 9.0.02, which includes excellent data dashboards and visualization effects."
"The flexibility of the solution is quite good."
"In the past we used the different application to collect logs. We used SurfWatch and VMware to do so. But, we found that the Splunk has more capacity to do more in less time. They provide a aster speed to index all the events , and this is a huge asset."
"The most valuable features of Splunk Enterprise Security are its high-performance data collection, flexible query language, and its versatility across the organization."
"The ability to manage large amounts of generated data and to protect all devices from unauthorized use are the most valuable features."
"It gives us good visibility into multiple environments, including cloud, on-premises, and hybrid; irrespective of platform."
"Graylog can improve the index rotation as it's quite a complex solution."
"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 needs to improve their authentication. Also, the fact that Graylog displays logs from the top down is just ridiculous."
"The infrastructure cost is the main issue. I like the rest. If the infrastructure costs could be lower, it would be fantastic."
"It would be great if Graylog could provide a better Python package in order to make it easier to use for the Python community."
"There should be some user groups and an auto sign-in feature."
"With technical support, you are on your own without an enterprise license."
"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-"
"It needs integration with a configuration management solution."
"We do have to educate developers on how to not blow it up. It is a little to easy to write an expensive query and overly stress the system. This could be improved."
"Splunk can improve its third-party device application plugins."
"Splunk is very expensive. The license is based on the volume of the logs ingested. I was responsible for managing the contract with our service integrator. I don't know the precise details of the competing solution, but I have heard that Splunk is more expensive than others. I don't know what the going rate is on the market, but I think there are at least two competitors that are less expensive. We have experienced a few issues with our service providers in terms of log filtering and ingestion, so we continue to pay a bit more per day for our logs."
"This is not really a monitoring solution."
"The UI can be improved. Dashboards and reports can be better in terms of graphics."
"The CIM model is the method Splunk uses to normalize data and categorize its important parts, but it is quite complex."
"The upgrading process could be smoother."
