  • Ingesting various log sources
  • Dashboards - Customisable
  • Event alerts/emails
  • 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

  • Nice search interface and powerful search options
  • JSON extractor to "extract" variables and values from JSON input.
  • Clear and intuitive dashboards
  • In the front end, the search "tricks" could have been made a little easier to find. There seems to be some kind of "search language" where you can use keywords like "AND" and "OR," etc. (much like SQL language). But it's totally unclear what does work and what doesn't. If you don't know that it's there, you'll never find it. Of course, after you do know it, you can find many examples online on how to use it.
  • The backend is not for the inexperienced. Graylog is based on elastic search and MongoDB. And it's Linux. This means that Graylog is actually 3 applications that you need to configure in a Linux environment. This means that you need quite some experience to get this running. Fortunately, though, things are kept as simple as possible. What I mean is that at first, the task seems daunting, but then you'll find that there's not much to it after all.
  • We've had multiple occasions that disk size was full or indexes went larger than allowed. When this happens, the systems can become corrupt. The solution is to just delete the indexes, but it took quite some time to find this out.
  • We disabled "Automatic updates" on the Linux server because unattended updates always lead to problems. This is not a real problem, or solely related to Graylog, but worth mentioning. Updates are best handled manually.

  • The free edition is extraordinarily powerful.
  • Log searching is quick.
  • The web interface is sleek, and the install is relatively quick.
  • Rotating the indexes are hard! It is also easy to brick your deployment. Purchase support, but it's so ludicrously expensive, that I'd go with a different vendor.
  • Community support dances around questions and points to documentation, which is there, but is not always accurate.
  • Searching logs uses logic that is not always easy to use.
  • There is not a good way to size how much space you need for a given log retention. It also does not tolerate running out of space using a smart feature or such to auto delete. The heap can also overflow.
  • It uses MangoDB instead of a different database.
  • The OVA is not approved for production use.
  • It is resource intensive.

  • The ability to add and remove information to the messages. This makes it so you can customize each message and get the information you really want.
  • Being able to search for different criteria allows finding the exact data you want without having to manually filter the data.
  • Searching tends to be quick and is able to process large amounts of data quickly so you don't have to wait forever for your data.
  • The graphs and visualizations are limited on the dashboard if there were more options it would be better for different kinds of data.

  • 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).
  • Some aspects of Graylog are less than intuitive. For example, if you want to run different extractor rules on different device types due to format differences, you need to create different inputs. Since inputs are their own processes that require ports to be bound to them, you either need different IP addresses for each input or a different (read: non-standard) port, which can make the device configuration more complicated.
  • Although Graylog abstracts quite a bit of Elasticsearch management away, it is by no means a turnkey solution. Upgrades to Graylog can require upgrades to Elasticsearch, which occasionally requires manual intervention to Elasticsearch. Same goes for mongo. If you're looking to scale out, there is some documentation to get you started, but the heavy lifting is on you.
  • As everything is stored in Elasticsearch, there are no more flat files to tail; moving from a "traditional" logging aggregator like Syslog(-ng), a culture change is going to be required.
