Download Td-agent

If you're looking for more lightweight forwarder for edge devices / servers / containers, use Fluent Bit, an open source data collector specifically designed for data forwarding. Fluent Bit is more efficient in terms of CPU / Memory usage, but has limited features. The following table list the available Linux packages for different distributions. Note that Fluent Bit packaged is known as td-agent-bit.

This version uses Fluentd v0.12 and the Ruby version is 2.5/2.1. This article describes the differences between td-agent2 and td-agent3. td-agent2 is for existing td-agent2 and fluentd v0.12 users. If you have new deployment, try td-agent3 version first.

Both processes run as the td-agent user under td-agent group and all forked subprocesses run as the same. This applies to any system call initiated by td-agent as well. The agent configuration resides at /etc/td-agent/td-agent.conf. All configurations must be readable by td-agent.

I have installed td-agent and they provide an init.d script that you can run it with, I have configured td-agent and I run it via the init.d script and it's running smoothly, but I want to move td-agent to be running under Supervisor, I have reread and updated supervisor and my conf of fluentd looks like this.

When I typed "service td-agent start", I saw "Starting td-agent: [ OK ]".To check it, I typed "service td-agent status", but I saw "td-agent dead but pid file exists".I don't understand this result.Please tell me how to solve this.

In addition to checking permissions as suggested above, delete your pid file before you restart td-agent. The pid file tracks the process ID for td-agent when you start the service. If yours isn't located at /var/run/td-agent/ then check /etc/init.d/td-agent and look for something like $PIDFILE

A shell script is provided to automate the installation process for each version. The shell script registers a new apt repository at /etc/apt/sources.list.d/treasure-data.list and installs the td-agent deb package.

The logs are located under /var/log/td-agent. The daemon is running in td-agent user and td-agent group.

The config file is located at /etc/td-agent/td-agent.conf. After its modification, restart the agent.

This cookbook may be used on Amazon Linux but we cannot guarantee if td-agent will work properly because

AWS doesn't guarantee binary compatibility with RHEL (they aim to be "as compatible as possible").

If users encounter any compatibility issues with td-agent on Amazon Linux, they should contact AWS.

pinning_version and version attributes are now available for rpm package.

The td-agent repository now use reprepro for building Deb repository.

reprepro can not handle multiple versions of the same package.

Access to the API may be turend off by setting enable_api to false. This may be of particular use when

td-agent is being used on endpoint systems that are forwarding logs to a centralized td-agent server.

Fluent Bit/td-agent-bit[1] is an open source and multi-platform Log Processor and Forwarder which allows you to collect data/logs from different sources, unify and send them to multiple destinations.

In our environment, we are using Elasticsearch to store web logs and we also use td-agent to pass data to elasticsearch. Elasticsearch version is 7.2.0, Kibana version is 7.2.0 and td-agent version is 3.4.0

Thanks for reply. I have checked at the same time, the elasticsearch health status is green and it is working properly. Is there any possibility that chunk size sent by td-agent is larger than elasticsearch supports at a time, so elasticsearch refuses connection. can I know the largest request at a time supported by elasticsearch. My elasticsearch server has 16GB memory and in JVM I have given -Xms8g -Xmx8g.

For example, nginx can read /etc/letsencrypt/live because the master process is run by root, but fluentd/td-agent starts itself under td-agent, and so it does not have read access to the certificates/private keys.

Edit: Took a bit of time to understand what all those flags mean. I also had to run setfacl -m u:td-agent:rX /etc/letsencrypt/{live,archive} as that is the directory that td-agent had trouble getting into.

When combining -enterprise/version-3.0/openshift-enterprise-30-administrator-guide/chapter-5-aggregating-container-logs with to forward OpenShift log messages into a graylog instance the td-agent fails.

The servers don't have internet access to download rubygems so I downloaded the current version from manually. The versions seem to be incomaptible

To troubleshoot errors, if you encounter any during log collection or during the set up, see docs.fluentd.org. If you use td-agent, then you can use the log file /var/log/td-agent/td-agent.log to debug issues.

Step 1: Getting Fluentd

Fluentd is available as a Ruby gem (gem install fluentd). Also, Treasure Data packages it with all the dependencies as td-agent. Here, we proceed with td-agent. I assume that you are on Ubuntu Precise (12.04), but td-agent is also available for Ubuntu Lucid and CentOS 5/6 with the support for Ubuntu Trusty forthcoming.

To send the application to Azure Log Analytics, add the following entries to the FluentD configuration file at /etc/td-agent/td-agent.conf. Note that you need to substitute the customer_id and shared_key values with the values you copied from your Log Analytics workspace.

That all looks hunky dory, but what on earth is all that td-agent business, you ask? It turns out that the company Treasure Data maintains most (all?) stable distribution packages of FluentD. Hence, the FluentD agent is called td-agent in these distributions. You can read more about it in the official FluentD FAQ, but suffice to say that td-agent is equivalent to FluentD for our purposes. Keep in mind though, this does mean that command names, configuration files, etc will carry the td-agent name instead.

Insert the following lines into /etc/td-agent.conf. I use UDP port 5140 to receive flows in my lab, though you can change this to other ports if you like. Remember to point the NetFlow Exporter to the right UDP port later.

These are the main Fluentd configuration files used to forward events to the Collector. The file locations are /etc/otel/collector/fluentd/fluent.conf on Linux and C:\opt\td-agent\etc\td-agent\td-agent.conf on Windows. By default, these files configure Fluentd to include custom Fluentd sources and forward all log events with the @SPLUNK label to the Collector.

This directory contains the custom Fluentd configuration files. The location is /etc/otel/collector/fluentd/conf.d on Linux and \opt\td-agent\etc\td-agent\conf.d on Windows. All files in this directory ending with the .conf extension are automatically included by Fluentd, including \opt\td-agent\etc\td-agent\conf.d\eventlog.conf on Windows. 006ab0faaa
