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

Pros
Real-time UDP/GELF logging and full text-based searching.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.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.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.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 have scaled from a single machine installation (a VM with a Graylog + ES + MongoDB) to (2 Graylog + 2 ES + 3 MongoDB). This was done smoothly with a minimal impact on logging.

The initial setup is simple, not very complex. Initial deployment takes around 10 to 15 minutes to set up the entire base for Splunk including all three tiers.The search function for spam is like a google search. You just enter and it will quickly show you the results.It's very flexible. If you look from the cloud implementation it is there. Reports are made quickly. Unlike other tools, it caters to all kinds of technical information on the front very easily. There's no need to put in any technical information. You can pull on the reports very easily, take action, and notify stakeholders.It's extremely scalable. It's a very robust solution and certainly has the capability of handling far bigger data requirements than a lot of the other tools. Generally what ends up happening with me is that my clients tend, for the most part, to be mid-tier organizations where the cost of that solutions would be accompanying requirements for people just becomes way too prohibitive. Especially considering the model that they use for costing, which is based on the volume of data. Of course, they're going to put everything including the Coke machine as the ability to collect data off of it, because of course the more they can put through the tool the more money they make.It is quite extensible. It is a platform that we can build our use instead of each case instead of each case being limited or restricted to each capability. This is probably the best feature.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 dashboards are the most valuable feature. We like the ability to drill in and see what queries are under the dashboard, build new visualizations, edit the querying, and see the reports.We were able to create a catalog of dashboards and have a holistic view at all levels. We could understand our business much better. Real-time errors, which were buried in emails before now, surfaced up on dashboards.

Cons
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.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.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.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-Dashboards, stream alerts and parsing could be improved.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.There should be some user groups and an auto sign-in feature.​

Splunk does not build apps. They only go back and validate the apps that somebody has already built. They should have remote consulting support. They have a wonderful solution. They have 24/7 security. Nobody needs to depend on any third party and will therefore just buy Splunk on the cloud.Spam has different plugins but by default, the logs are not organized, it shows that there are roll-ups that are out of the box. I saw many plugins that can help improve or extend Splunk's functionality but I haven't tried any of them.It does not give us permission to implement on-premise so we implement them on the cloud.The tool itself is very difficult to configure. It's great for its number of inputs, for the different types of systems devices, and things that it could collect information from. To actually make good use of it, you need a fairly dedicated team of people that have some reasonably good programming or modeling skills to be able to do the things that you need to do with it. Whereas a lot of the other tools are better packaged for that, and so require a lot less training and a lot less dedication.I would like to see future development in terms of ML (Machine Learning).I think the tech support response time could be a bit better. Sometimes I need to wait more than 24 hours for a response to my tickets.Splunk is not very user-friendly. It has a complex architecture in comparison to other solutions on the market.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.

Pricing and Cost Advice
​You get a lot out-of-the-box with the non-enterprise version, so give it a try first.Consider Enterprise support if you have atypical needs or setup requirements.​If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​I am using a community edition. I have not looked at the enterprise offering from Graylog.Having paid official support is wise for projects.

Splunk's cost is very high. They need to review the pricing. They have to go back and totally readdress the market.It's a little bit expensive for a small to medium enterprise.I think the price could be improved.I am not personally involved with the pricing of the solution.Some of the insights that we have obtained as a part of using Splunk have greatly helped us in increasing our revenue in terms of selling our products.The pricing seems good relative to the other vendors that we have had here. However, they need to find ways to be more flexible with the licensing and be able to deal with situations where we start generating more logs. Maybe having some controls in the Splunk interface to turn it off, so we don't have to change anything in our application.We have had a reduction in the time it takes to resolve issues and correlate what has failed.It would be nice if the pricing were cheaper. However, we did purchase it.
