Linux core-dump location and abrtd configuration

Question

I'm trying to change the Linux (RHEL6.7) core-dump location to a different directory using the abrtd configuration

(normally it is going to the location core,but according to my research, if you enable abrtd, that will overwrite the default location.)

cat /proc/sys/kernel/core_pattern
/var/tmp/core-%e-%p-%t

abrtd.conf dump location looks like this

DumpLocation = /data/kdump/abrt/FQDN    (this is a nfs mount)

Why my application core-dumps are not going to the /data/kdump/abrt/FQDN rather /var/tmp location

Am i missing any configuration directive ?

I don't know which linux you're using, but you need to change the core_pattern so that it includes a pipe with the path to abrt binary, like so:

cat /proc/sys/kernel/core_pattern
|/usr/libexec/abrt-hook-ccpp /var/spool/abrt %s %c %p %u %g %t %h %e 636f726500

That way the system knows that the core dump is to be piped through to abrt. The value was taken from here: https://access.redhat.com/solutions/61536
