Heavy Forwarder – You can use a Heavy forwarder and eliminate half your problems, because one level of data processing happens at the source itself before forwarding data to the indexer. Why go through the trouble of transferring all the data to the Indexers and then filter out only the relevant data? Wouldn’t it be better to only send the relevant data to the Indexer and save on bandwidth, time and money? This can be solved by using Heavy forwarders which I have explained below. Since there is minimal processing on the data before it is forwarded, lot of unnecessary data is also forwarded to the indexer resulting in performance overheads. It is a simple component which performs minimal processing on the incoming data streams before forwarding them to an indexer.ĭata transfer is a major problem with almost every tool in the market. Universal Forwarder – You can opt for an universal forwarder if you want to forward the raw data collected at the source. Now, let us understand the different types of Splunk forwarders. You can scale them up to tens of thousands of remote systems easily, and collect terabytes of data with minimal impact on performance. To understand how real time forwarding of data happens, you can read my blog on how Domino’s is using Splunk to gain operational efficiency.Ĭompared to other traditional monitoring tools, Splunk Forwarder consumes very less cpu ~1-2%. You can install them in multiple systems and collect the data simultaneously from different machines in real time. You can configure the forwarders to send data to Splunk indexers in real-time. What if you want to do real-time analysis of the data? Splunk forwarders can be used for that purpose too. In fact, you can install several such forwarders in multiple machines, which will forward the log data to a Splunk Indexer for processing and storage. Suppose, you want to collect logs from a remote machine, then you can accomplish that by using Splunk’s remote forwarders which are independent of the main Splunk instance. Splunk Forwarder is the component which you have to use for collecting the logs.
