New log management solution

[vohmar]

With moving whois server to cloud platform it's necessary to rethink the log management. Two main topics here

• where to save logs (central log repository on premise and local logs with the application in cloud) and how to keep the repositories in sync?
• how to access logs?

Tasks - what to consider:

• what application to use? (greylog?)
• timestamping - logs are currently timestamped, it should be possible to timestamp logs in the log managemen application so it is possible to finetune what to log and what not
• The solution must be scalable to other registry applications and the registry system

1. To reduce log size we should consider using something like LogRage.
2. We might find useful to keep logs in some external platform like LogDNA, NewRelic or DataDog (in last two setups we also could use their application performance monitors) - that's de-facto kind of a standard approach in RoR applications.
3. If we still want something self-hosted/self-setted-up, then ELK-stack for the win!
