As part of https://phabricator.wikimedia.org/T336041, I'll be provisioning kafka-jumbo10[10-15].eqiad.wmnet brokers (1010 is already up). It seems that these brokers need to be added to your configuration to resolve some CRITICAL: kafka-jumbo1010:down, kafka-jumbo1010:unconfigured alerts.
Feel free to reach out with any questions. Thanks!
