Properties: Panopticon

The majority of configuration options for the server are set in the Panopticon.properties file in the <appdata> directory (e.g., C:\vizserverdata\). If this file does not exist when the server starts, it will create it with all default values. When the
server starts after an upgrade, it may add new properties and remove deprecated ones.

You can optionally move sensitive properties like passwords and URLs from this file, where they are stored in clear text, into a file named Secret.properties in the same directory. The Secret.properties file stores values encrypted, and you can manage it with PCLI. A property can only be defined in one of these files at a time.

The following properties can be set in the property files:

connector.kdb.host.lookup.script

 

Description

Full path of the shell script file that is accessible on the server. When set, before making a new kdb+ connection, this script is executed to get the host info. This
property helps in overriding connection details entered inside the kdb+ connector UI centrally, and may help when different authentications are set at kdb+ like Kerberos/Custom etc. The output of this script is expected to be a JSON object like below.

{ "host": "localhost", "port": 5001, "username": "", "password": "" }

NOTE: Starting with the 21.2 release, the the kdb+ connection pool feature of Panopticon (kdb.connection.pool.xx) can be used together wth the host lookup. So any new connection request from the pool, will first execute the script set here, to get the host info before the pool is looked up for available connections.

Examples:

  • For Windows

  • any file modified inside /objects/

NOTE: There may be dangling files in the /objects/ directory or those that are not in use. These files are typically results of failed saves and/or sync conflicts. The check may or may not detect deleted or modified dangling files, but that is not critical.

 

Default Value

false

 

Property

Repository Import

 

Attribute

repository.startup.import.paths

 

Description

NOTE: Use this property to make the server import content at startup. This is imported on top of the existing content and will always overwrite anything that is already there. This property can be useful for example, if you have multiple servers with different content but you want the latest version of a standard set of workbooks to be deployed on all of them. This property only has effect on a stand-alone or leader server.

This property is the list of paths to directories and files, separated by the system specific path separator “;” on Windows and “:” on Linux. Each directory is scanned and imported keeping its local tree structure.

For example, workbooks to be imported are placed in a folder and in this property, the absolute path to that folder is specified.

ADDITIONAL NOTES:

  • User-specific folders (e.g., “~john/”) can be targeted this way, but only if they already exist on the server.

  • Bundles (exz files) directly listed in the property or found in directories listed are also imported, but always to the root, with their internal structure preserved.

  • Files that are not legacy workbooks or bundles are ignored.

  • The same set of workbooks will get imported over and over (startup, user edit, restart) and for bundles (nothing changes in the history the second time), but legacy workbooks change their meta data.

  • The import always overwrites local changes (it resets the workbooks in the repository).

Permissions are not supported, and any folders created will have “SYSTEM” as owner.

Default Value

 

 

Property

Data table regression testing

 

Attribute

startup.regression.datatable.include.folders

 

Description

Comma-separated list of folders to test.

The default is blank, which means the root folder and all workbooks will be tested. If you list folders here, then only the data tables in workbooks in these folders will be tested, unless also excluded. Folder paths should include a trailing backslash, and you need to use double backslashes since this is the escape character in Java property files. For example, to only include prod and qa\final, you should set the property to "prod\\,qa\\final\\" (without quotes).

 

Default Value

 

 

Property

Data table regression testing

 

Attribute

startup.regression.datatable.runonce

 

Description

If set to true, the server will run a data table regression test during the next startup. The property is immediately reset to false, so you need to set it to true again to run another test.

Default Value

true

 

Property

Subscription

 

Attribute

subscription.broadcasting.pool.max.size

 

Description

The maximum number of threads for the broadcasting thread pools of refresh events.

The default value is empty, which means that there is no limit. Any value less than 1 also means that there is no limit. When setting a max value for the thread pools, it means that the pool cannot create more than that number of threads. If there are more concurrent events handled by the thread pools than there are threads, they are queued until a thread becomes available.

The thread pools are also configured to only increase the pool size if all threads are busy and a new event needs to be processed. If a thread is idle more than 1 minute, it will be removed from the pool and the size of the pool thereby decreases.

Any subscription for a static data source are scheduled to refresh each X seconds (based of the refresh period of the datatable) using the TaskScheduled built in to Spring.

If multiple subscriptions with the same data query tries to load data at the same time, only one thread will actually load the data. The rest of the subscriptions are queued. When the data is loaded all waiting subscriptions will be given the same data set that are then broadcasted to their respective client.

 

Default Value

 

 

Property

Subscription

 

Attribute

subscription.compression.delta.enabled

 

Description

With delta compression, the server only sends the difference from the last data result on each refresh. For data where only a fraction changes on each refresh, this means much smaller response messages.

The trade-offs are that both client and server need to keep the last result to calculate the difference and apply it, and that this operation takes some additional time both on the server and the client.

In rare cases, delta compression may worsen performance, e.g., if you have a large data set with very high refresh rate and a large portion of the data changes on each refresh. You can then disable delta processing completely by setting this property to false.

 

Default Value

true

 

Property

Subscription

 

Attribute

subscription.compression.enabled

 

Description

Enable or disable compression and encoding of subscription broadcast messages.

 

Default Value

true

 

Property

Subscription

 

Attribute

subscription.congestion.control.enabled

 

Description

When the server loads data for a subscription, it checks that the previous data load for it has completed. If not, it might be a sign that the refresh rate is set too high on the data table. If this happens subscription.maximum.failure times in a row, the server will cancel the subscription. Set this property to false to disable this behavior.

 

Default Value

true

 

Property

Subscription

 

Attribute

subscription.data.loading.pool.max.size

 

Description

The maximum number of threads for loading thread pools of refresh events.

The default value is empty, which means that there is no limit. Any value less than 1 also means that there is no limit. When setting a max value for the thread pools, it means that the pool cannot create more than that number of threads. If there are
more concurrent events handled by the thread pools than there are threads, they are queued until a thread becomes available.

The thread pools are also configured to only increase the pool size if all threads are busy and a new event needs to be processed. If a thread is idle more than 1 minute, it will be removed from the pool and the size of the pool thereby decreases.

When the data is loaded all waiting subscriptions will be given the same data set that are then broadcasted to their respective client.

 

Default Value

 

 

Property

Subscription

 

Attribute

subscription.data_log.always_on

 

Description

When set to true, the data log is always passed from server to client if the user is a Designer or Admin on the server. Previously, the data log would only be passed for workbooks in design mode.

The data log will be passed also when the data request fails. The “Invalid Configuration” message shown in the visualization will show a “Data Log” button, which will display the relevant logs and error message. 

NOTE: The actual passing of runtime exception is currently implemented in the Kdb+ connector only.

The benefit of running a server with subscription.data.log.always_on=true is that, the data log is more easily accessed and can be viewed both as success and failure. The data log can also be viewed without having Write permissions on the folder where
the workbook is used, which is helpful when connection failures need to be examined in production environments where you have restrictions on workbook editing. 

NOTE: Viewer users are not able to view the Data Log, only Designers and Admins.

Attribute

subscription.log.slow.data.loads.seconds

 

Description

Logs a subscription that has been loading data for more than X seconds at a WARNING level.

NOTES:

  • Any integer less than 1 (or an empty value) will disable the logging.

  • If a slow data load has been logged and then returns data, a log message at INFO level will be printed stating that a previously logged slow data load has returned data.

 

Default Value

60

 

Property

Subscription

 

Attribute

subscription.maximum.failure

 

Description

The amount of time a subscription is allowed to fail in a row before it should be cancelled. The number will be reset to zero if data loading is successful. The maximum failure limit is used so that invalid subscription will not loop forever and fill the logs with error messages. The value -1 will disable the fail mechanism. This means that a subscription can fail endless of times and not be cancelled.
