Logs and troubleshooting (Release TWO)

Logs

UI logs

The server-side UI logs can be obtained on the SO-ub container at:

/usr/rift/usr/share/rw.ui/skyquake/err.log
/usr/rift/usr/share/rw.ui/skyquake/out.log

Client side UI logs can be obtained in the Developer Console in a browser.

SO logs

SO logs can be obtained on the SO-ub container at:

/var/log/rift/rift.log

RO logs

RO logs are at file "/var/log/osm/openmano.log" on the RO container. You can get it from the container to the OSM machine with:

lxc file pull RO/var/log/osm/openmano.log .

Log file and log level (debug by default) can be set at file "/etc/osm/openmanod.cfg" on RO container

Troubleshooting

Troubleshooting UI

UI status

• The status of the UI process can be checked by running the following command in the SO-ub container as root:

forever list

• You should see a status similar to following with an uptime:

info:    Forever processes running
data:        uid  command         script                                                                                                                 forever pid   id logfile                    uptime
data:    [0] uivz /usr/bin/nodejs skyquake.js --enable-https --keyfile-path=/usr/rift/etc/ssl/current.key --certfile-path=/usr/rift/etc/ssl/current.cert 21071   21082    /root/.forever/forever.log 0:18:12:3.231

• In case the UI server process has issues, you won't see an uptime but will instead see a status "STOPPED" in that position.
• In case the UI server process never started, you'll see a status saying "No forever processes running".

Restarting UI

• The UI is restarted when the SO module (launchpad) is restarted.
• However, in case just the UI needs to be restarted, you can run the following command in the SO-ub container as root:

forever restartall

Troubleshooting SO

SO status

The SO now starts as a service, but earlier versions of the SO used to run SO as a process. To check if the SO is running as a service, run the following command:

lxc exec SO-ub systemctl status launchpad.service

Restarting SO

Note: Restarting the SO also restarts the UI.

When the SO has been started as a service (see SO status section above), use the following commands to restart the SO:

lxc exec SO-ub systemctl stop launchpad.service
lxc exec SO-ub systemctl start launchpad.service

When SO hasn't been started as a service, please follow the following instructions to restart the SO

lxc restart SO-ub # Optional, Needed if there is an existing running instance of launchpad
lxc exec SO-ub -- nohup sudo -b -H /usr/rift/rift-shell -r -i /usr/rift -a /usr/rift/.artifacts -- ./demos/launchpad.py --use-xml-mode

Troubleshooting RO

RO status

The status of the RO process can be checked by running the following command in the RO container as root:

 service osm-ro status
● osm-ro.service - openmano server
   Loaded: loaded (/etc/systemd/system/osm-ro.service; disabled; vendor preset: enabled)
   Active: active (running) since Wed 2017-04-02 16:50:21 UTC; 2s ago
 Main PID: 550 (python)
    Tasks: 1
   Memory: 51.2M
      CPU: 717ms
   CGroup: /system.slice/osm-ro.service
           └─550 python openmanod -c /etc/osm/openmanod.cfg --log-file=/var/log/osm/openmano.log

Nov 02 16:50:21 RO-integration systemd[1]: Started openmano server.

In case it is not running, try to see the last logs at /var/log/osm/openmano.log

Restarting RO

RO can be restarted on the RO container at:

service osm-ro restart

Known error messages in the RO and their solution

Possible known errors are:

Invalid openstack credentials

SYMPTOM: At deployment it appears some of the following error messages:

• Not possible to get_networks_list from VIM: AuthorizationFailure: Authorization Failed: The resource could not be found. (HTTPS: 404)
• VIM Exception vimconnUnexpectedResponse Unauthorized: The request you have made requieres authentication. (HTTP 401) ...

CAUSE: Openstack is not properly added to openmano with the right credentials

SOLUTION:

• See the steps at OSM_Release_TWO#Openstack_site. If the problem persist ensure openstack is properly configured.
• Ensure you have access to the openstack endpoints: if port 5000 is redirected using iptables, other endpoint ports must also be redirected.
• Use "v2" authorization URL. "v3" is currently experimental in the master branch and is not recommended.
• If https (instead of http) is used for authorization URL, you can either use the insecure option at datacenter-create (See Openstack_configuration_(Release_TWO)#Add_openstack_at_OSM); or install the certificate at RO container, by e.g. putting a .crt (not .pem) certificate at /usr/local/share/ca-certificates and running update-ca-certificates.

Can be checked using openstack client from RO container:

lxc exec RO bash    # for entering the RO container CLI
openstack --os-project-name <project-name> --os-auth-url <auth-url> --os-username <auth-username> --os-password <auth-password> --debug network list 
openstack --os-project-name <project-name> --os-auth-url <auth-url> --os-username <auth-username> --os-password <auth-password> --debug host list 
openstack --os-project-name <project-name> --os-auth-url <auth-url> --os-username <auth-username> --os-password <auth-password> --debug flavor list 
openstack --os-project-name <project-name> --os-auth-url <auth-url> --os-username <auth-username> --os-password <auth-password> --debug server list 
#providing the same URL, credentials as you provide to openmano. The (--debug) will show more info so that you will see the IP/ports it try to access
#run 'openmano datacenter-list <datacenter-nanme> -vvv' to see openstack credentials

Wrong database version

SYMPTOM: osm-ro service fails. At openmano logs appear:

2016-11-02T17:19:51 CRITICAL  openmano openmanod:268 DATABASE wrong version '0.15'.                                 Try to upgrade/downgrade to version '0.16' with 'database_utils/migrate_mano_db.sh'

CAUSE: Openmano has been upgraded with a new version that requieres a new database version.

SOLUTION: To upgrade de database version run database_utils/migrate_mano_db.sh and provide credentials if needed (by default database user is 'mano', and database password is 'manopw')

Troubleshooting VCA

VCA status

lxc exec VCA -- juju status

Check that juju account is in 'green' status in the UI

lxc exec VCA -- juju config <app> 

lxc exec VCA -- juju list-actions <app> 

lxc exec VCA -- juju show-action-status 

lxc exec VCA -- juju show-action-output <action-id> 

Software upgrade (source code)

OSM is being upgraded periodically to fix bugs that are being reported. Last version corresponds with the tag v1.0.5. These guidelines show you how to upgrade the different components.

UI upgrade source code

Note: It is recommended to upgrade both SO and UI modules together.

Execute at UI container ("lxc exec SO-ub bash" to enter into the container, "exit" to exit)

cd /root/UI
git pull --rebase
git checkout tags/v2.0.1
make clean && make -j16 && make install

Follow SO upgrade to upgrade SO and restart launchpad.

SO upgrade source code

Execute at SO container ("lxc exec SO-ub bash" to enter into the container, "exit" to exit)

cd /root/SO
git pull --rebase
git checkout tags/v2.0.1
make clean  # Clean the previous installation
./BUILD.sh   # Install the new version

Exit from SO-container and restart SO-ub container and Launchpad

lxc restart SO-ub
# lxc exec SO-ub -- nohup sudo -b -H /usr/rift/rift-shell -r -i /usr/rift -a /usr/rift/.artifacts -- ./demos/launchpad.py --use-xml-mode

RO upgrade source code

Execute at RO container ("lxc exec RO bash" to enter into the container, "exit" to exit)

service osm-ro stop
#git -C /opt/openmano stash        #required if the original config file has changed
git -C /opt/openmano pull --rebase
git -C /opt/openmano checkout tags/v2.0.1
#git -C /opt/openmano stash pop     #required if the original file has changed
/opt/openmano/database_utils/migrate_mano_db.sh 
service osm-ro start
