Subject: [lttng-dev] lttng-sessiond as a CentOS 7 service
Date: Wed, 12 Oct 2016 18:21:19 +0000 [thread overview]
Message-ID: <48CF5AC71E61DB46B70D0F388054EFFDB7DF18EF@VAL-E-01.valcartier.drdc-rddc.gc.ca> (raw)

Using:
lttng-modules-stable-2.8-2.8.2-e840206
userspace-rcu-stable-0.9-6051170
lttng-ust-stable-2.8-cf18865
lttng-tools-stable-2.8-2.8.2-48262f1
on:
Red Hat Enterprise Linux Server release 7.2 (Maipo) (RHEL 7.2 64-bits)
Kernel 3.10.0-327.el7.x86_64
I'm having trouble with my installation of lttng-sessiond as a service. If I run lttng-sessiond using either -b, -d, or just -vvv, it works fine (I can interrogate 'lttng list -u' from a tracing user shell and detect the process using 'ps -e | grep sessiond').
But when I launch the service, I end up with a "successfully dead" daemon:
# systemctl start lttng-sessiond
# systemctl status lttng-sessiond
* lttng-sessiond.service - LTTng central tracing registry session daemon
Loaded: loaded (/etc/systemd/system/lttng-sessiond.service; enabled; vendor preset: enabled)
Active: inactive (dead) since ...
Process: 5865 ExecStart=/usr/local/bin/lttng-sessiond -d (code=exited, status=0/SUCCESS)
Main PID: 5865 (code=exited, status=0/SUCCESS)
There's nothing in dmesg.
The service is set up like so:
$ sudo ln -s /etc/systemd/system/lttng-sessiond.service /etc/systemd/system/multi-user.target.wants/lttng-sessiond.service
$ cat > ~/lttng-sessiond.service << END
[Unit]
Description=LTTng central tracing registry session daemon
[Service]
Type=simple
User=root
ExecStart=/usr/local/bin/lttng-sessiond -d
Restart=on-abort
[Install]
WantedBy=multi-user.target
END
$ sudo mv ~/lttng-sessiond.service /etc/systemd/system/lttng-sessiond.service
What am I doing wrong?
