Grafana Loki vs. Graylog

In our application there are many points from where logs are coming so in order to go to each and every application and check logs its very overhead so we are using Grafana Loki for the logs gathering and monitoring.

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.

• Access to many open-source dashboards, access to add many data-sources to gather and visualize data from.
• Grafana Loki does well gathering of logs from various data-sources, we can also filter the logs based on our needs.
• One stop solution for all the logs and monitoring.

Incentivized

• 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).

Incentivized

• We can modify the logs directly from UI of Grafana Loki
• Better and simplified options for logs filtering
• Easy usability with SMTP configuration and other system level configuration

Incentivized

• 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

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.

First and foremost if Grafana Loki is based on CNCF open source projects so organizations can get freedom to choice to configure it at your own other main thing is Grafana Loki is totally free of cost and we can deploy it on our infrastructure. On compared with other managed services like Datadog, New Relic it is very expensive and we also don't have much control on the tools we use.

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.

Incentivized

• Only indexes the metadata
• Have to manage it by ourselves compare to other available managed monitoring and log observability solutions
• Dedicated person or team of SRE to manage the monitoring and observability solutions

Incentivized

• 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.
