We will parse nginx web server logs, as it’s one of the easiest use cases.
MINIFI VS FILEBEATS HOW TO
In this example, sidecar has been installed on a Windows host and is checking in already, so we need to configure the input and the collection of the logs.įirst, we need to create the input on the Graylog server, at System -> Inputs. Here we explain how to send logs to ElasticSearch using Beats (aka File Beats) and Logstash.
CONFIGURATION OF GRAYLOG SIDECAR FOR FILEBEATĪfter you know the location of the logs you want to collect by the filebeat agent, we can configure Graylog to do the collection. The position is also needed to be kept across service restarts or system reboots to ensure no logs are left behind so that everything is sent to Graylog for long term retention. While this is sufficient in normal operations, but during peak hours, it does not seem to scale to 10-12k EPS.
For this example, we will use the DNS Query logging collection, but the process can be applied to any flat text file collection.įilebeat allows for the collection of the local files while maintaining their position on the collection, so you don’t end up re-gathering the same logs again and again. FileBeat at no point of time crosses more than 7k-8k EPS. WHAT IS FILEBEAT USED FOR?įilebeat is used for the collection of local text files, not present in the Microsoft event channel logs. Graylog Sidecar can run on both Linux and Windows devices, but in this article, we will discuss the Windows version. Graylog sidecar can help by creating and managing a centralized configuration for a filebeat agent, to gather these types of logs across all your infrastructure hosts. Have you ever needed to grab a log from a local server that is not part of the Windows Event Channel? Applications like IIS or DNS can write their logs to a local file, and you need to get them into your centralized logging server for correlation and visualization.
