The putback of
PSARC 2008/046 Process Contract Decorations
5079353 RFE: contract 'decoration' with service FMRI
has provided process contracts with terms describing service FMRI and
additional information that will identify the origin of the process
contract. This information will also be available postmortem.
You can use ctstat(1) to view the new terms as shown below:
$ ctstat -vi 1,4
CTID ZONEID TYPE STATE HOLDER EVENTS QTIME NTIME
1 0 process owned 0 0 - -
cookie: 0
informative event set: none
critical event set: none
fatal event set: hwerr
parameter set: noorphan
member processes: 1
inherited contracts: none
service fmri: svc:/system/init:default
service fmri ctid: 1
creator: sched
aux:
4 0 process owned 1 0 - -
cookie: 0x1
informative event set: none
critical event set: empty
fatal event set: core signal hwerr
parameter set: inherit regent
member processes: 100004
inherited contracts: none
service fmri: svc:/system/svc/restarter:default
service fmri ctid: 4
creator: init
aux: smf
In this case we have the information of the process contracts for
init(1M) and svc.startd(1M)
Here is a simple example of dtrace to cont syscall by service fmri:
# dtrace -qn 'syscall:::entry {
@[stringof(curthread->t_procp->p_ct_process->conp_svc_fmri->rs_string)]
= count(); }'
^C
svc:/system/filesystem/autofs:default 2
svc:/system/fmd:default 2
svc:/network/inetd:default 4
svc:/network/nfs/cbd:default 12
svc:/system/intrd:default 13
svc:/system/svc/restarter:default 20
svc:/system/sysevent:default 23
svc:/system/console-login:default 24
svc:/system/sac:default 30
svc:/network/smtp:sendmail 74
svc:/system/svc/repository:default 156
svc:/system/name-service-cache:default 329
svc:/system/webconsole:console 535
svc:/network/ssh:default 2308
There is an RFE (6667501) filed to create stable interfaces to access
some process contract terms directly.
More details can be found in the man page for process(4)
The source code is already in opensolaris.
Please file any bugs in solaris/utility/smf
