Considered Both Products
Graylog
Chose Graylog
Blackfire and Sentry both offer more resources, not only monitoring logs but also performance and real time erros - on those areas they are more complete and generalistic tools. Graylog, however, is better on log saving, search and analysis alone, because of its flexible and …
Chose Graylog
Graylog has the simplest deployment, and it is ready to work in a few clicks. Although we also use Grafana and Zabbix in our environment, the role of processing log data is better suited to Graylog. In our case, we use Graylog to process and analyze web application logs, such …
Chose Graylog
Azure Monitor is not exactly what I mean, but I couldn't find Azure Application Insights. Anyway, for a large organization, Azure makes more sense than using Graylog because a lot of logging will already be inside Azure. And you don't want to have two "central" logging …

We use the free edition, because it is free and open source. We evaluated numerous other products, but we decided to go down the Graylog track because of initial costs. While the competition (Splunk, AlienVault, etc.) are very good products and come highly recommended, it …

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 …

Graylog does what other similar products that cost more do, but the more expansive one typically has more features or are multiple products wrapped in one. We went with Graylog because it does everything we need it too, and the price was less than other and fit into our budget. …
Chose Graylog
We previously used Syslog(-ng) and considered moving to the Logstash with Kibana as part of the standard ELK stack as we are consumers of ELK in other scenarios, but we determined that maintaining a distributed Graylog system was going to require less work overtime for our main …
Chose Graylog
Graylog provides some great functionality for free. There are some more premium products that would handle more logs and would be a little easier to configure.

Splunk does a good job at log aggregation and compatibility however, integrations with other products is been a challenge. Especially the pricing can be more competitive to spice up the market and orgs looking to explore AI based logging over traditional practices.

Able to show more than Log data in Splunk views, we tested several plug-ins during a small pilot, and we were able to bring O/S (Win/Unix/Linux) & APM data metrics into the same views as Logged data. I've seen others use it to visualize a wider range of data types, too...better …

GraylogSplunk Enterprise
Likelihood to Recommend
If you already have a basic understanding of Elasticsearch and/or MongoDB, Graylog will be a great fit when it comes to log aggregation. It will be a decent option even if you don't have any experience but have the time and willingness to roll up your sleeves that learning those tools will require. Graylog supports plugins to extend functionality for things like SNMP traps, telemetry collection, and solar flares. As is the case with most software with plugins, if the core functionality for which you are looking (i.e. not logging) is based on a plugin, Graylog probably isn't for you. The majority of the plugins in the marketplace are developed by third-parties looking to solve their specific use case so bug fixes and new features are not a given.

I'm liking the newer products, and I'm looking forward to how they integrate with the overall product when they come together. Just log in and be able to query a large number of systems for similar issues or a unique one. That is a great fit for Splunk Enterprise, looking for a simple case or a simple String or something of that nature across multiple machines. It's a great fit for that to identify issues or particular software, whatever your scenario is, String, to find it across any particular server or group of servers, so that you can update or do a deployment or whatever it is you're looking to do.

Cons
  • Configuration can be hard to understand
  • More quickly and easy ways to search for data
  • Auto-categorization of log entries would be excellent
Read full review
  • At times some queries can run slowly if indices are not on a portion of the query you use.
  • Setup time initially can be difficult if your logs aren't stored in common locations or in a common way to write the log.
  • Ability to ingest logs from different locations without having to change code to put logs in a certain place (pro and con).
  • Searches can be a bit more difficult to look through if your log isn't pulled in a manner that is easy to read through splunk.

We are using Splunk extensively in our projects and we have recently upgraded to Splunk version 6.0 which is quite efficient and giving expected results. We keep track of updates and new features Splunk introduces periodically and try to introduce those features in our day to day activities for improvement in our reporting system and other tasks.

Usability
Graylog is more on the technical side of user interface, with a steep learning curve that can be challenging for non-tech people. Once its logic is understood, however, its great to use and people have no issues to find the information they need. It's configuration is also not that easy, however this we consider impossible to avoid in spite of the type of service it does
Read full review
Splunk usability could be a little more friendly on correlations and log analysis. not for end users, but for the tech team, sometimes is hard to find good professionals to set up integrations and new dashboards when needed. For the high-level management, it can be overwhelming to read Splunk dashboards.

Support Rating
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.

Splunk maintains a well resourced support system that has been consistent since we purchased the product. They help out in a timely manner and provide expert level information as needed. We typically open cases online and communicate when possible via e-mail and are able to resolve most issues with that method.

The online course was simple clear and described the main capabilities of the solution. There is also an initial module that can be done for free so anyone can familiarize themselves with the functionality of this solution. On the other hand, however, there could be more free online courses. Maybe even with a certificate, this would broaden the group of people who are familiar with the platform while increasing familiarity with the solution itself.

Azure Monitor is not exactly what I mean, but I couldn't find Azure Application Insights. Anyway, for a large organization, Azure makes more sense than using Graylog because a lot of logging will already be inside Azure. And you don't want to have two "central" logging locations. But Azure is chaos and highly "not intuitive." So for small and mid-size organizations, Graylog is still the better option.

A lot of products have natively inside their own dashboards and or their own logging repositories. And each one is difficult to learn or they're too complex or they're not verbose in the sense that they're not easy to mine the data that you're looking for. So that could be anything from the native logging that you find in other Cisco products. It's easier to use Splunk to draw the data that you're looking for as opposed to going to the individual's products themselves to get the logs that you're looking for.
