Missing entries in syslog?

[alan6854321]

Hi there,

I've been investigating dnsmasq crashes when the WAN goes down and I've noticed that not all entries are written to the syslog file on the router.
I run a separate syslog server and that receives messages that are not written to the syslog file.
Is this any kind of known issue?

Example, this is what I see in the syslog file on the router.

Jan 14 10:00:36 Samba_Server: smb daemon is stopped
Jan 14 10:00:37 rc_service: udhcpc_wan 3061:notify_rc start_samba
Jan 14 10:00:37 custom_script: Running /jffs/scripts/service-event (args: start samba)
Jan 14 10:00:37 custom_config: Appending content of /jffs/configs/dnsmasq.conf.add.
Jan 14 10:00:37 custom_script: Running /jffs/scripts/dnsmasq.postconf (args: /etc/dnsmasq.conf)
Jan 14 10:00:38 Samba_Server: daemon is started
Jan 14 10:00:38 dhcp_client: bound 92.40.72.69/255.255.255.252 via 92.40.72.70 for 120 seconds.

But this is what my syslog server captured for the same period

You don't have the router's logging level set high enough. The dnsmasq messages are at info and debug level.

So everything gets sent to the syslog server, regardless of those settings?

Yes.
