You can try sar (from sysstat package) for getting historical activity information like memory/CPU utilization, Disk IO, Swap usage - though I haven't seen if the disk full is recorded.
Or you can try munin, nagios, metricbeat(with ELK stack), graylog. Though you'll need these applications installed to record events. You can't get info directly from the CentOS logs (maybe OOM killer info from kernel logs, but that will be max. you can get)

systat utilities default 'history' = 7 days
I set mine to 30 when I have to install it.
