If One Identity Safeguard for Privileged Sessions (SPS) audits lots of connections, processing and indexing the created audit trails requires significant computing resources, which may not be available in the SPS appliance. To decrease the load on the SPS appliance, you can install the indexer service on external Linux hosts. These external indexer hosts run the same indexer service as the SPS appliance, and can index audit trails, or generate screenshots and replayable video files from the audit trails as needed. The external indexers register on SPS, wait for SPS to send an audit trail to process, process the audit trail, then return the processed data to SPS. The external indexer hosts do not store any data, thus any sensitive data is available on the host while it is being processed.

To use external indexers to process your audit trails, you have to complete the following steps.
