Compatibility between forwarders and Splunk Enterprise indexers
The following table shows which versions of forwarder and indexer are compatible. A best practice is to use indexers with versions that are the same or higher than forwarder versions.
Determine forwarder-indexer compatibility
The following table shows the versions of forwarder and indexer that can be used together. As a best practice, use indexers that are the same or higher version than the forwarders. If the forwarder version you want to use is not in this table, then there is no support for it.
- An X in a cell indicates that this version of forwarder can send event data to the corresponding version of indexer.
- An M in a cell indicates that this version of forwarder can send both event data and metrics data to the corresponding version of indexer.
- An S in a cell indicates that this version of forwarder can send data to this version of indexer after you change the Secure Sockets Layer (SSL)/Transport Layer Security (TLS) version and cipher suite on the forwarder.
- An empty cell indicates that Splunk does not support sending any type of data from this version of forwarder to the corresponding version of indexer.
For app-specific compatibility restrictions, see the app documentation on Splunkbase.
