[12:47:20] <Majavah>	 hi, beta cluster host deployment-webperf12 has `arclamp` which depends on a redis server running on deployment-fluorine02. deployment-fluorine02 is on Jessie and being decomissioned in favour of deployment-mwlog01, are there any docs on what arclamp is and how its database can be safely moved?
[12:48:54] <Krinkle>	 Majavah: no database to move, it's a pubsub channel
[12:49:11] <Krinkle>	 https://wikitech.wikimedia.org/wiki/Performance/Runbook/Arc_Lamp_service
[12:49:44] <Krinkle>	 There is a variable in wmf-config that tells MW which Redis to send performance samples to
[12:49:52] <Krinkle>	 and there is a hiera variable that tells Arc Lamp where to read it from
[12:52:00] <Majavah>	 Krinkle: thanks!
