influx_stress usage and configuration

The binary for influx_stress comes bundled with all influx installations. To run it against an influxd instance located at localhost:8086 with the default configuration options:

See more about the default configuration options

$ influx_stress

To run influx_stress with a configuration file:

$ influx_stress -config my_awesome_test.toml

To daemonize influx_stress and save the output to a results file:

$ influx_stress -config my_awesome_test.toml > my_awesome_test_out.txt 2>&1 &

To run multiple instances of influx_stress just change the measurement each test writes to, details below

$ influx_stress -config my_awesome_test1.toml > my_awesome_test_out1.txt 2>&1 &
$ influx_stress -config my_awesome_test2.toml > my_awesome_test_out2.txt 2>&1 &

Below is a sample configuration file with comments explaining the different options

# The [provision] section creates a new database on the target instance for the stress test to write points to and perform queries against
# This section can be deleted if the instance is manually configured. In that case make sure that the database referenced in [write] exists
# The provisioner will try to delete the database before trying to recreate it.
