Hidden Costs Breakdown

1

Infrastructure Setup Complexity

medium implementation

Graylog requires configuring three separate applications (Graylog, Elasticsearch, and MongoDB) in a Linux environment. Setup demands significant technical expertise and is not suitable for inexperienced administrators.

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.

2

Disk Storage Management and Index Corruption

high implementation

Disk space can fill up unexpectedly or indexes can exceed size limits, causing system corruption. When this occurs, indexes must be deleted manually. Requires ongoing monitoring and maintenance to prevent data loss.

trustradius · 2022-01-18

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.

3

Manual Update Management Required

low support

Automatic updates can lead to system problems. Organizations must disable automatic updates and manage them manually, requiring dedicated admin time and testing procedures.

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.
