Graylog
For small companies, Graylog is the best solution possible. It's easy to configure and "just works." Above everything else, it's free. The only thing I hold against it is the fact that it's Linux-based. [This] makes sense because Elasticsearch is Linux-based. But Linux adds a layer of complexity that we don't need for something basic as a logging server. I'm pretty sure that we would have had a logging server years earlier if I had to convince quite a few decision-making people to go ahead with it anyway.

[Sentry] is honestly an amazing product. It allows us to detect errors in real time complete with stack traces and any extra accompanying information the developer wants to provide in the alert. With the alerting into Slack it has allowed us to quickly triage and tag in people who need eyes on a specific issue. It would be really useful in any Saas product environment.

Graylog
- Graylog does a great job of its core function: log aggregation, retention, and searching.
- Graylog has a very flexible configuration. The backend for storage is Elasticsearch and MongoDB is used to store the configuration. You have to option to make your configuration as simple as possible by storing everything on one box, or you can scale everything out horizontally by using a cluster of Elasticsearch nodes and MongoDB servers with several Graylog servers pointed to all the necessary nodes.
- Graylog does a good job of abstracting away a fair portion of Elasticsearch index management (sharding, creation, deletion, rotation, etc).

- Great web interface. Lots of data available in a really clean format, with filtering options and more.
- Per-user exception tracking. User is complaining about something being broken? Look up their account ID in Sentry and you can see if they've run into any exceptions (with device information included, of course).
- Source map uploading. Took a little while to figure this out but now we have our deploy script upload sourcemaps to Sentry on each deployment, meaning we get to see stack traces that aren't obfuscated!
- Very generous free tier – 10,000 events per month. We're nowhere near that yet.

Cons
Graylog
- Support for more log sources
- Event alerts/emails - Some cases where unable to separate data from multiple clients, and no easy fix
- API - Limits results to 10,000 and can cause server to lockup on queries that exceed the limit

- The UI is overwhelming and it takes time to "digest it"
- It would have been nice to have the ability to "group together" minor releases into one that represents a bigger release

Community support does not give simple straightforward answers; simply search up Graylog Issues and look at some of the responses on the forums. The documentation is your only hope if you are on the free version, as you can NOT purchase only support. The few times I have worked with Graylog Enterprise support they were great though.

Graylog
In terms of log aggregation, the free product fully stacks up with the competitors listed. Full control over the data ingests for flexible configuration. Graylog even better on that front than AlienVault USM because you cannot configure the variable mapping. We haven't used the threat exchange stuff or correlation. But with regex searches, we have created function dashboards that show threat theater pictures of our network based on logs from our firewall.

I think Sentry is far more user-friendly and has a better UI. Sentry is also a more affordable option.

Return on Investment
Graylog
- Graylog is just less expensive than some other options which meant it fit into our budget otherwise we might not be able to justify a higher cost.
- Being able to track issues that we normally couldn't track using other tools is a bonus to help us know of any issues we have and can fix before an outage or failure that could potentially cost money.
- We have had to spend more time than I would like to understand and customize Graylog which has taken time away from other tasks and projects.

- The first notice of an issue more than paid for it for the month.
- However, it's not as useful if you aren’t doing active development.
