Configuring server options
Config options are used to enable or disable certain features or behavior in ftrack. They are specified on the ftrack server in
/opt/ftrack_config/ftrack.ini under the [DEFAULT] section. After modifying the config file ftrack must be restarted for the changes to apply.
A service secret is required to have internal services working properly. A secret needs to be generated and added to the ini file.
ftrack.service_secret = SOME_SECRET
The secret should be random and at least 36 characters long. A secret can be generated like this:
python -c 'import uuid;print uuid.uuid4()'
The server URL needs to be set to let ftrack know what URL your users will be using to connect to the server. The URL is used to generate emails correctly and ensure some of the internal services are working properly. The URL should contain protocol.
ftrack.server_url = http://my-company-ftrack
The URL must be accessible from the ftrack server as it will also be used for internal communication.
Email settings should be configured to allow the ftrack server to send out notifications via email.
# Turbomail config.
mail.on = true
mail.transport = smtp
mail.smtp.server = YOUR-SMTP-SERVER_URL:PORT
mail.encoding = utf-8
mail.smtp.username = USERNAME
mail.smtp.password = PASSWORD
mail.message.author = ftrack
You can also configure ftrack to send error emails when a server error happens using:
# Error email config.
ftrack.error_email = ftrack-error@YOUR-COMPANY.com
ftrack.smtp_server = YOUR-SMTP-SERVER_URL:PORT
ftrack.from_address = ftrack
ftrack.smtp_username = USERNAME
ftrack.smtp_password = PASSWORD
Note: We recommend that you track errors with sentry instead of via emails.
Tip: You can test sending emails from the ftrack diagnostics page in system settings. Either to your user, or by triggering a server error which will send to the error email config.
PDF export font
Specify the font file that should be used when exporting a PDF.
ftrack.pdf_export_font_path = /ABSOLUTE_PATH_TO_FONT/FONT.ttf
Note: The path have to be an absolute path and the font must be in ttf format.
Specify a folder with JSON configuration files.
The configuration files are loaded when the server starts. To apply new changes, the server needs to be restarted.
ftrack.form_layout_path = /PATH/TO/FOLDER/WITH/LAYOUTS
Due date in Tasks widget
Enable due date column in Tasks widget in sidebar.
Configure Web server
The main ftrack server is using uWSGI which has a lot of configuration options that can be used to tune ftrack for better performance.
Always use a staging server when tuning ftrack to test various options before deploying in production.
The default options are passed to uwsgi when it is started but can be overridden in the ftrack ini file by adding a uwsgi section:
processes = 15
By default ftrack will use 10 processes and that should be enough for most scenarios. Each process have 10 threads that are responsible of serving requests. Increasing the number of processes will allow the ftrack server to serve more requests at the same time.
Each process will consume additional RAM which may increase slightly over time. There is also a certain ratio between number of CPUs on your server and the number of processes that make the server efficient. As an example, having 2 CPU cores and 20 processes is likely not going to result in better performance when the number of concurrent requests against the server is high.
If you are running the database on the same server you should make sure you never run out of RAM since that will likely result in the database failing to allocate memory and crash.
Tuning a server is not an exact science as it depends on a lot of factors. Keep an eye on CPU usage and disk IO when tuning your server to get an idea of what is the main bottleneck. There are a few tools that can be used to monitor the processes and the number of requests they serve.
/opt/ftrack/environments/ngxtop/bin/ngxtop -l /tmp/ftrack_nginx.log
Can be used to monitor all requests passing through Nginx and look at their response codes in real time. ngxtop parses the access log and can also be used to look and past requests like this:
/opt/ftrack/environments/ngxtop/bin/ngxtop -l /tmp/ftrack_nginx.log --no-follow
The processes running in uWSGI can be monitored individually to ensure they are serving content properly using:
Track exceptions with sentry
Sentry can be used to capture exceptions happening in ftrack to see when and how often they occur. To capture exceptions with sentry the ftrack.ini file needs to be updated with the following:
ftrack.sentry = true
To use sentry on your local install you need to have a sentry account and there you can find your sentry dsn.
You can also use sentry to track exception which occur in client-side applications by creating a new project in Sentry and adding the corresponding public DSN key to the configuration file.
ftrack.sentry_dsn_ftrack_spark_overview = https://...
Fetch update events directly from internal queue
Update events can be listened to using the event hub in the API. Sometimes it is useful to get the events directly from the internal events queue to guarantee that no events are missed due to dropped connections or similar between the API and the event server.
For this to work, the event server must enable use of the amqp messaging queue via the configuration option:
ftrack.enable_amqp_event_server = true
This feature will be enabled by default in later releases.
When an event is generated on the ftrack server it is added to the amqp messaging queue via an exchange called ftrack-events. The ftrack event server will register a queue bound to that exchange called ftrack-event-server-queue and use that to process the events. If you want to gather the events directly from the amqp messaging queue you can register your own queue via the same exchange and read the events from there. This ensures that events are never missed even if your script is restarted.
Override the default create project behavior
You can override the default behavior when a user chooses to create a new project to invoke an action instead of displaying the default dialog:
# Set to an action identifier to be launched when creating a project
ftrack.create_project_action_identifier = test.company.create-project
An minimal example action which creates a project is available here:
If you need to override the default create project behavior, but are running in a cloud hosted environment, please let us know at email@example.com.
Encrypted client side cookie based sessions can be used instead of file based sessions with ftrack. The client side sessions will not store session files on the ftrack server which is useful when scaling out as ftrack can be run on multiple servers and still share sessions and also avoids hitting inode limit on the server. Read more about the beaker session configuration options in the beaker documentation.
beaker.session.key = ftserver
beaker.session.type = cookie
beaker.session.secure = true # Only set if using https.
beaker.session.cookie_expires = false
beaker.session.httponly = true
beaker.session.validate_key = <A SECRET KEY>
beaker.session.encrypt_key = <ANOTHER FAIRLY LONG SECRET KEY>
It may be difficult to estimate how much memory ftrack will use, and it may vary depending on how many processes you configure uwsgi to use. Some modules may also leak memory over time. If you database is running on the same server you may want to limit how much memory uwsgi can use:
lazy-apps = true
reload-on-rss = 1000
evil-reload-on-rss = 1500
worker-reload-mercy = 10
What are the options:
- lazy-apps: Saves some memory on master process.
- reload-on-rss: Soft memory limit for a uwsgi process in MB.
- evil-reload-on-rss: Hard memory limit for a uwsgi process in MB.
- worker-reload-mercy: Seconds a process will wait for current requests to finish before reloading.
Setting these options in the ftrack.ini file will give you a better estimate on how much memory will be used. With these settings uwsgi will likely not use more than (reload-on-rss * processes) MB, but having the evil-reload-on-rss set higher will allow for bursts when needed.
