![]() ![]() However, it should be noted that the use of Heavy Forwarder increases network traffic, CPU and memory usage. One of the key advantages of Heavy Forwarder is that it can filter unwanted events, even in unstructured data, which will reduce the amount of indexing, and the size of the license depends on it. Īlthough Universal Forwarder is the preferred way to send data, you may need Heavy Forwarder if you need to analyze or make changes to the data before sending it, or you will need to control where the data is going, based on its content. How to install and configure Universal Forwarder can be found here. You can analyze the incoming data stream before indexing only if it is structured data.It is not possible to locally perform indexing and search queries.To achieve better performance, Universal Forwarder has several limitations: Although it does not have a web interface, it can still be customized, managed and scaled by editing configuration files. Universal Forwarder is available as a separate installation package and includes only the necessary components necessary for sending data to other instances of the Splunk platform. It can be installed not only on Windows, Linux and Mac OS, like Splunk Enterprise, but also on Solaris, FreeBSD and AIX. It is also more scalable than other Splunk products, since you can install over a thousand instances that will not greatly affect network and host performance.Īnother advantage is its availability for installation on many different platforms. It loads less CPU, uses less memory and takes up less disk space. The most notable advantage is that Universal Forwarder uses significantly less hardware resources than other Splunk software products. Therefore, it is often recommended to use it, if there are no specific prerequisites for using Heavy Forwarder, which we will discuss below. Universal Forwarder has several advantages over using Heavy Forwarder. Heavy Forwarder, which is a full-fledged Splunk Enterprise, which, in addition to data transfer, can index, perform search queries and modify data.Universal Forwarder, which contains only those components that are required to transfer data.In total there are 2 types of forwarders : Metadata labeling (source, source type and host)Īfter you have decided that you will send data using forwarders, the following question arises: which is the best forwarder to use?.Data transfer can be carried out in various ways, but the most common of these is the use of forwarders. In the article we will briefly describe what it is, what types are there, what is the difference between them and in what situations it is better to use one or another forwarder.Ĭorrect data loading is the most problematic issue in any data handling system. Today we will talk about agents (forwarders) for loading data into Splunk.
