Hi everybody, I am about to reboot eventlog1001 for kernel upgrades. This host runs all the Eventlogging daemons that pull data from Kafka, elaborate it and then push to Mysql. The maintenance is needed to deploy the new Linux Kernel that fixes the Meltdown vulnerability.
If you see a dip in Eventlogging schema metrics ( https://grafana.wikimedia.org/dashboard/db/eventlogging-schema?orgId=1) it will be my fault :) Thanks! Luca (on behalf of the Analytics team)
