Description Eric Rich 2019-01-25 21:26:35 UTC

Description of problem: Today if you collect logs using this method (oc adm node-logs) you only get the node/journal logs for the current boot. 

Having an option or the ability to span multiple boots/reboots will help with our ability to troubleshoot and diagnose issues. 

How reproducible: 100%


Steps to Reproduce:
1. Get logs for a service (oc adm node-logs --role master -u NetworkManager.service)
2. Reboot a master or all masters
3. Get logs for a service (oc adm node-logs --role master -u NetworkManager.service)

Actual results: you only get the logs from the current boot.

Expected results: We should have an option or flag to request logs from prior boots.
