Missing entries in log files just before/after reboot

Hello world,

One of the servers, a Fedora one,rebooted today (Luckily, a testbox).
I tried to get the reason the server rebooted. After going through the messages, I think that the log entries just before and after reboot are missing.
Please below: (****** is the server name, for privacy reason)

 
Mar 12 15:28:35 ****** snmpd[9415]: Connection from UDP: [10.235.49.62]:65118
Mar 12 15:28:35 ****** snmpd[9415]: warning: /etc/hosts.allow, line 11: missing ":" separator
Mar 12 15:28:35 ****** snmpd[9415]: Connection from UDP: [10.235.49.62]:65118
Mar 12 15:28:35 ****** snmpd[9415]: warning: /etc/hosts.allow, line 11: missing ":" separator
Mar 12 15:28:35 ****** snmpd[9415]: Connection from UDP: [10.235.49.62]:65118
Mar 12 16:06:39 ****** rsyslogd: [origin software="rsyslogd" swVersion="2.0.2" x-pid="1592" x-info="[x-configinfo/"]http://www.rsyslog.com"][x-configInfo udpReception="No" udpPort
="514" tcpReception="No" tcpPort="0"] restart
Mar 12 16:06:39 ****** kernel: rklogd 2.0.2, log source = /proc/kmsg started.

I understand there will be no logs during the reboot but, why exactly did the server reboot? I have two doubts:
1.Was the SNPD process with the error "missing ":" separator" the cause for reboot?
2. Why did rsyslogd run immediately aftyer the reboot? Can it help me trace the reboot cause?

Thanks in Advance.:slight_smile:
