Fluentd is an open source data collector which can be used to collect event logs from multiple sources. It filters, buffers and transforms the data before forwarding to one or more destinations, including Logstash.
gem install fluent-plugin-logit
Add the following to your fluentd configuration.
<match **> @type logit stack_id port "Port not found, contact support" buffer_type file buffer_path /tmp/ flush_interval 2s </match>
match clause is correct for the events you wish to send to Logit.io. Buffering is optional but recommended.
Fluentd was developed by Treasure Data & initially released in 2011. Fluentd often draws comparisons with Logstash as both log collectors share some similarities especially when it comes to platform compatibility.
Where these tools differ though can be seen clearly across their configuration difficulty & performance (Logstash is notably easier to configure).
Fluentd on the other hand is known for requiring minimal system resources & can be used with Fluent Bit for an even more lightweight method of forwarding your data.
Fluentd is used by many of the world's biggest technology companies, including Atlassian, Microsoft & AWS.
For this configuration guide, we’ve covered using both Logstash & Fluentd together for forwarding your data for further log analysis and processing using ELK (Elasticsearch, Logstash & Kibana).
Fluentd is also often used alongside Bigquery as a scalable method of performing queries against log data from Google Cloud. A centralised platform for log management can easily prove a more than suitable replacement for this, such as the platform we have here at Logit.
The Logit.io platform is built to allow you to drive data-driven insights from your logs & brings together Fluentd & Logstash for full observability of your logs in a single centralised platform. Our platform offers a complete solution for centralising your log files from multiple applications and servers and provides a Fluentd log analyser as standard.
If you need any more help with migrating your Fluentd to Logstash the Logit.io team are here to help. Feel free to visit our Help Centre or get in contact with our support team by sending us a message via live chat & we'll be happy to assist.
