Thanks Dave for the response.
But I don’t see the syslog getting generated under /var/log/.

I am running VPP process as below.
vpp -c /etc/vpp.conf

And I have the unix section of vpp.conf file as below.


unix {

   nodaemon

   log /var/log/vpp.log

   full-coredump

   gid vpp

   cli-listen localhost:5002

}

Am I missing something here to get the syslog generated? BTW I am running 
stable 18_07.

Thanks,
Leela sankar

Make sure to check e.g. /var/log/syslog. Clib_warnings(...) are sent to syslog, 
and end up in the system log. Search for “vnet”. Example:

Dec 11 07:37:56 vpp-n1 vnet[2977]: icmp6_router_solicitation:1811: Prefix 
[REDACTED] valid 295722 preferred 295722

FWIW... Dave

Subject: [vpp-dev] How to enable logs in VPP?

Hello,

I am looking for some information on how to enable error-logs, warnings, etc.
I see bunch of logging in the code like clib_error_xxx(), clib_warning_xxx(), 
etc.

Can someone share how to enable these logs to capture to a file on the target?

Thanks,
Leela sankar
