How to log segfaults / core dumps to syslog
All:
In GNU/Linux && FreeBSD, syslogd(8) tracks /dev/klog which gets appended to when segfaults / coredumps (and other signal/abnormal exits) happen. This results in coredumps getting syslogged for offload to an NMS such as OpenView or other.
dmesg(8) on HP-UX doesn't seem to have these.
Is there a kctune(8) argument I need to run to enable this? Older pre 11.23 posts suggest a "alwaysdump" or "dump_all" tuneable flag. Running B.11.23
Any advise? Thanks, ~Brian

Re: How to log segfaults / core dumps to syslog
I don't think any application aborts get logged at all. Not unless you have a signal handler and call syslog(2).
And you can use coreadm(1m) to put the corefiles in a central location.

YIKES!
So I'd have to request this feature as a HP-UX kernel new feature request (NFR), in light of all the GNU/Linux efforts?

It looks like it.
