No, you need to be able to identify which logs are from jmeter and send those logs to a different index.
For example, your normal logs you will send to the application index and the logs from jmeter will be sent to the application-jmeter index.
I never used OpenShift Logging and don't know how this works, but you need to be able to send logs to different indices based on some conditionals that identify the log as being generated by jmeter requests or not.
