Graylog Scalability

It's pretty scalable. We didn't hit any ceiling when scaling it up. You throw hardware at it, and it just performs fine. The only issue is the cost. It's not dependent on how big an instance you have. The problem is that it costs a fortune.

We have about 300 users, but it's not about the users. It's about the traffic we have. Our traffic is pretty big. We have thousands of messages going per second through the Graylog instance. It's not that we have many users making queries concurrently, but still, to have the data ready for querying, Graylog needs to crunch it, process it, and write it to Elasticsearch, and that's what consumes resources most of the time.

Graylog can scale, but technically, Graylog's scalability mainly depends on Elasticsearch because it uses Elasticsearch as the backend. I would say the question should probably be about how well Elasticsearch can scale. The answer to that would be that it is pretty scalable, but it's not simple. It's not like Kubernetes, where you just add a few extra replicas and you get performance right of the box. It's a bit complex to scale it, but it is scalable.

We have approximately 40 to 45 people using the solution in my company. There are three different teams using it, such as developers and testing teams. The teams use the solution on a daily basis.

We have 50-60 users of the solution. Its scalability gets complicated when we have to update or edit multiple nodes. It is a very tedious task to add new nodes to the cluster. I rate its scalability a six.

No scaling issues that I have seen with the three nodes of MongoDB and the three nodes of Elasticsearch. I will transition to have HA, load balancers, and buffering/queues as we move forward. I see things have changed in the latest version, or current -1 that I am using right now. I see durability is defined, I just need to reach out and implement it.

We've grown from 500 to 2,000 independent devices on this solution, and it captures them all. We even plan to increase our usage. So, yes, the program is scalable.

We never attempted to scale the environment, as its sizing is defined in the planning phase and it fitted us later perfectly.

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.
