Porting the analytics EventLogging processes running on eventlog1001 from analytics Kafka to jumbo-eqiad Kafka should be relatively simple, so let's do it soon.
=== Steps
# Create eventlogging-client-side and eventlogging-valid-mixed topics in jumbo-eqiad Kafka.
# Configure varnishkafka eventlogging to use jumbo-eqiad Kafka and restart varnishkafka eventlogging processes.
# Let EventLogging consume and process all remaining events in eventlogging-client-side topic in analytics Kafka.
# Stop EventLogging.
# Configure EventLogging processes to use jumbo-eqiad Kafka.
# Start EventLogging.
# Let webperf consumer on hafnium consume remaining events in analytics Kafka.
# Configure webperf consumer to use jumbo-eqiad Kafka and restart webperf on hafnium.
# Let EventLogging Camus job consume all remaining EventLogging events in analytics Kafka.
# Configure new EventLogging Camus job to consume from jumbo-eqiad Kafka. This will require a new camus history directory in the camus properties, as there will be new offsets to work from in jumbo-eqiad.
# Configure EventLogging analytics grafana dashboards to use jumbo-eqiad.
