    Considered Both Products
    Graylog
    Chose Graylog
    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 …

    Chose 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 …

    Chose Graylog
    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 Splunk Enterprise
    Both Logstash and Greylog are open-source solutions that provide similar capabilities to Splunk. They are excellent products in their own right but tend to follow versus lead. Splunk is definitely a leader in the field.

    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.

    It's well suited for what I do, which is network security operations. And that's for anything from troubleshooting incidents, troubleshooting performance, troubleshooting for the purpose of a compliance and auditing. It's not best suited for users who are new in terms of they're new to the product and they have expectations that probably Splunk cannot meet.

    Pros
    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).

    • It is very useful in creating custom rules for analyzing system logs and display relevant information. The query language is very easy to learn.
    • We can create custom UI to visualize the output of our data. The interface is very flexible. It also allows the sharing of rules among users.
    • There is an open online community to help others. Stackoverflow also has a splunk community. These resources make it more convenient to learn.

    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

    • Splunk light limits number of users to 5. Wish there was a flexible license, where one could add more users.
    • Splunk light does not let you add > few realtime alerts. Wish there was a flexible license, where one could add as many realtime alerts as wanted.
    • Better insight into daily ingestion values

    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.

    You can literally throw in a single word into Splunk and it will pull back all instances of that word across all of your logs for the time span you select (provided you have permission to see that data). We have several users who have taken a few of the free courses from Splunk that are able to pull data out of it everyday with little help at all.

    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.

    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 didn't get to fully evaluate Logstash as our corporation was already using Logstash, but both seemed like viable solutions to the problem that we were having. I wanted to evaluate Logstash some more, both did seem like they would work for the business needs that we had, we went with splunk as many teams were already using it.

    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.

    • I don't have any numbers to share but Splunk has positively served as a 24/7 monitoring tool that has saved hours of work by self-detecting, saving statistics and alerting problems in the system or from external interfaces as soon as they happen.
    • Splunk dashboards does a solid job in collecting, analyzing data and creating reports that contain an entire day's activity and then automatically sent out to the business.
    • Splunk is very easy to learn and very useful to any program or business application.
