  "content": "\nUse the `memtier_benchmark` tool to perform a performance benchmark of Redis Enterprise Software.\n\nPrerequisites:\n\n- Redis Enterprise Software installed\n- A cluster configured\n- A database created\n\nFor help with the prerequisites, see the [Redis Enterprise Software quickstart]().\n\nIt is recommended to run memtier_benchmark on a separate node that is\nnot part of the cluster being tested. If you run it on a node of the\ncluster, be mindful that it affects the performance of both the\ncluster and memtier_benchmark.\n\n```sh\n/opt/redislabs/bin/memtier_benchmark -s $DB_HOST -p $DB_PORT -a $DB_PASSWORD -t 4 -R --ratio=1:1\n```\n\nThis command instructs memtier_benchmark to connect to your Redis\nEnterprise database and generates a load doing the following:\n\n- A 50/50 Set to Get ratio\n- Each object has random data in the value\n\n## Populate a database with testing data\n\nIf you need to populate a database with some test data for a proof of\nconcept, or failover testing, etc. here is an example for you.\n\n```sh\n/opt/redislabs/bin/memtier_benchmark -s $DB_HOST -p $DB_PORT -a $DB_PASSWORD -R -n allkeys -d 500 --key-pattern=P:P --ratio=1:0\n```\n\nThis command instructs memtier_benchmark to connect to your Redis\nEnterprise database and generates a load doing the following:\n\n- Write objects only, no reads\n- A 500 byte object\n- Each object has random data in the value\n- Each key has a random pattern, then a colon, followed by a\n    random pattern.\n\nRun this command until it fills up your database to where you want it\nfor testing. The easiest way to check is on the database metrics page.\n\n\n\nAnother use for memtier_benchmark is to populate a database with data\nfor failure testing.\n",
