Butler Spyglass is a tool for extracting metadata from Qlik Sense applications.
The tool will
- Extract data lineage for all or some applications.
- Extract load scripts for all or some applications.
- Extract complete info for all data connections.
- Run once or recurring at a configurable interval.
- Butler Spyglass
When using Sense in enterprise environments, there is often a need to understand both what apps use a certain data source, and what data sources are used by a specific app.
- When de-commissioning an old system that feed several Sense apps with data, it is important to know which these apps are. Butler Spyglass provide this information in the form of data lineage information.
- If a data source contains sensitive information, it is important to always have up-to-date information on what apps use the data source in question.
- Reviewing and auditing apps is greatly simplified if there is clear information on what data sources the app in question uses.
By storing all app load scripts as individual files on disk, it is possible to snapshot these daily and store them in one ZIP archive for each day. This becomes a historical record of what the scripts looked like in the past.
Traditional disk backups provide a similar capability to bring back old versions, experience has however proven it to be very valuable to have quick and easy access to old script versions, for example if apps have become corrupt or if there is a need to revert back to an earlier app version.
Butler Spyglass solves all the scenarios above by extracting both data lineage information as well as full load scripts for all apps.
Each release on the releases page contains info what is new, if there are any breaking changes that require special attention etc.
The change log also keeps a complete log of all details from all releases.
Extracted information for each app is
- Data lineage, i.e. what data sources are used by the app in question.
- Load scripts.
In addition to the above, complete definitions (except credentials, passwords etc) for all data connections in the Qlik Sense server are extracted and stored as CSV and JSON files.
Whether or not to extract data lineage info for apps is controlled by the configuration parameter ButlerSpyglass.lineageExtract.enable. Set to true/false as needed.
Data lineage information is stored in CSV and JSON files, one pair for each Sense app. Files are stored in the directory defined in ButlerSpyglass.lineageExtract.exportDir.
More info about discriminators and statements is found here.
Whether or not to extract app load scripts is controlled by the configuration parameter ButlerSpyglass.scriptExtract.enable. Set to true/false as needed.
Each app's load script is extracted and stored in a <appid>.qvs file in a folder as defined by the ButlerSpyglass.scriptExtract.exportDir configuration parameter.
Whether or not to extract data connection definitions is controlled by the config parameter ButlerSpyglass.dataConnectionExtract.enable. Set to true/false as needed.
Data connections are stored to dataconnection.json and dataconnection.csv in the directory specified by ButlerSpyglass.dataConnectionExtract.exportDir.
A template config file is available here.
How to name and where to store the config file is described here.
The parameters in the config file are described below. All parameters must be defined in the config file - run time errors will occur otherwise.
| Parameter | Description |
|---|---|
| logLevel | The level of details in the logs. Possible values are silly, debug, verbose, info, warn, error (in order of decreasing level of detail). |
| fileLogging | true/false to enable/disable logging to disk file |
| logDirectory | Subdirectory where log files are stored |
| extract.frequency | Time between extraction runs. 60000 means that the next extraction run will start 60 seconds after the previous one ends. Milliseconds |
| extract.itemInterval | Time between two sets of apps are extracted. The number of apps in a set is defined by extract.concurrentTasks (below). For example, if set to 500 there will be a 0.5 sec delay between sets of apps are sent to the Qlik Sense engine API. Milliseconds |
| extract.itemTimeout | Timeout for the call to the engine API. For example, if set to 5000 and no response has been received from the engine API within 5 seconds, an error will be thrown. Milliseconds |
| extract.concurrentTasks | Number of apps that will be sent in parallel to the engine API. Use with caution! You can easily affect performance of a Sense environment by setting this parameter too high. Start setting it low, then increase it while at the same time monitoring the realtime performance (mainly CPU) of the target server, to ensure it is not too heavily loaded by the data extraction tasks. |
| extract.enableScheduledExecution | true=start an extraction run extractFrequency milliseconds after the previous one finished. false=only run once, then exit |
| lineageExtract.enable | Controls whether to extract lineage info or not. true/false |
| lineageExtract.exportDir | Directory where lineage files should be stored. |
| lineageExtract.maxLengthDiscriminator | Max characters of discriminator field (=source or destination of data) to store in per-app lineage disk file |
| lineageExtract.maxLengthStatement | Max characters of statement field (e.g. SQL statement) to store in per-app lineage disk file |
| scriptExtract.enable | Controls whether load scripts are extracted to text files or not. true/false |
| scriptExtract.exportDir | Directory where script files will be stored. |
| dataConnectionExtract.enable | Controls whether data connections are extracted to JSON file not. true/false |
| dataConnectionExtract.exportDir | Directory where data connections JSON file will be stored. |
| appFilter.appNameExact | List of apps for which lineage and/or load scripts should be extracted. An exact match on app name is done. |
| appFilter.appId | App ids for which lineage and/or load scripts should be extracted. |
| appFilter.appTag | Lineage and/or load scripts will be extracted for apps with these tags set. |
| configEngine.engineVersion | Version of the Qlik Sense engine running on the target server. Version 12.612.0 should work with any Qlik Sense server from 2020 February and later. |
| configEngine.host | Host name, fully qualified domain name (=FQDN) or IP address of Qlik Sense Enterprise server where Qlik Engine Service (QES) is running. |
| configEngine.port | Should be 4747, unless configured otherwise in the QMC. |
| configEngine.useSSL | Set to true if https is used to communicate with the engine API. |
| configEngine.headers.X-Qlik-User | Sense user directory and user to be used when connecting to the engine API. UserDirectory=Internal;UserId=sa_repository is a system account. |
| configEngine.rejectUnauthorized | If set to true, strict checking will be done with respect to ssl certificates etc when connecting to the engine API. |
| configQRS.authentication | Method to authenticate with Qlik Repository Service. Valid options are: certificates. |
| configQRS.host | Host name, fully qualified domain name (=FQDN) or IP address of Qlik Sense Enterprise server where Qlik Repository Service (QRS) is running. |
| configQRS.port | Should be 4242, unless configured otherwise in the QMC. |
| configQRS.useSSL | Set to true if https is used to communicate with the repository API. |
| configQRS.headers.X-Qlik-User | Sense user directory and user to be used when connecting to the engine API. UserDirectory=Internal;UserId=sa_repository is a system account. |
| cert.clientCerCA | Root certificate, as exported from the QMC |
| cert.clientCert | Client certificate, as exported from the QMC |
| cert.clientCertKey | Client certificate key, as exported from the QMC |
All apps will be processed (=lineage and/or load scripts extracted ) if no app filters at all are set in the config file.
Console logs are always enabled, with configurable logging level (in the YAML config file).
Logging to disk files can be turned on/off via the YAML config file.
Log files on disk are rotated daily. They are kept for 30 days, after which the one(s) older than 30 days are deleted.
Lineage data is stored within each Sense app.
Each app from which lineage should be extracted must therefore be accessed.
The obvious approach is to get lineage data from one app, then move on to the next app.
This can take a long time on servers with thousands of apps though, Butler Spyglass therefore offers parallel extraction of lineage data.
Some settings in the config file offer fine-tuning of the extraction process:
ButlerSpyglass.extract.concurrentTaskscontrols how many apps will be processed in parallel.ButlerSpyglass.extract.itemIntervalcontrols how long a pause there will be before starting processing of another app.ButlerSpyglass.extract.itemTimeoutis the timeout after which Butler Spyglass will give up for a specific app.
An error will occur if lineage or load script for some reason cannot be extracted for an app.
Butler Spyglass keeps track of the ratio of successful extracts.
For example, the following text in the log means that all (100%) extracts have so far been successful:
Extracting metadata (#5, overall success rate 100%): fc90c7f0-f498-4780-8864-2f78f449d9e9 <<>> ✅ Qlik help pages
If the number is below 100% it means that one or more lineage/load script extracts failed.
There should be some info in the logs about which apps were affected and maybe also clues to what happened.
There is no installer, just download the binary for your OS from the releases page.
Then edit the config file as needed (there is a template config file here).
Place the config file in the config subdirectory in the directory where Butler Spyglass was started.
For example, if butler-spyglass.exe is stored in d:\tools\butler-spyglass, the config file should be stored in d:\tools\butler-spyglass\config.
You must also set the NODE_ENV environment variable to the name of the config file.
For example, if your config file is my-config-file.yaml the NODE_ENV environment variable should be set to my-config-file.
Butler Spyglass uses that variable to determine where to look for the config file.
The tree structure looks like this:
tree /FFolder PATH listing
Volume serial number is ....-....
C:.
│ butler-spyglass.exe
│
└───config
production.yaml
The NODE_ENV environment variable is set to production and the config file is called production.yaml.
In this example the certificates are stored elsewhere (not in a subfolder of the current folder). That's fine as long as the paths are correct.
type .\config\production.yaml---

...If ButlerSpyglass.enableScheduledExecution in the config file is set to true Butler Spyglass will keep running and do a data lineage extract run every ButlerSpyglass.extractFrequency milliseconds.
Using Docker is convenient and easy if you have an existing Docker or Kubernetes environment and know how to use those tools.
A few things to keep in mind though:
-
The NODE_ENV variable in the
docker-compose.ymlfile controls what config file will be used. If NODE_ENV is set to production, the file./config/production.yamlwill be used. -
The output directories defined in the
./config/production.yamlfile must match the volume mapping in the docker-compose.yml file.
I.e. if the config file defines the output directories as./out/lineageand./out/script, the docker-compose file must map the containers /nodeapp/out to an existing directory on the Docker host, for example./out:/nodeapp/out.
Looking at the directory structure and the config files, they could look as follows:
Directory structure:
.
├── config
│ ├── certificate
│ │ ├── client.pem
│ │ ├── client_key.pem
│ │ └── root.pem
│ └── production.yaml

...Each lineage file may contain zero or more rows, each representing a data source or destination that the app uses. Everything is included - even inline tables, resident loads, writing to QVDs etc.
This richness can be a problem though. If an inline table contains a thousand rows, all those rows will be returned as part of the lineage data.
That's where the maxLengthDiscriminator config option (in the config YAML file) comes in handy. It makes it possible to set a limit to how many characters should be included for each row of lineage data.
The setting is global for all apps, and applies to all rows of lineage data extracted from Sense.
Here is an example lineage file. Note that both QVDs, SQL statements and inline tables are included in the lineage data.

The load script .qvs files could be zipped into a daily archive by means of a scheduled task, using the standard OS scheduler.
Feel free to contribute with good analysis apps - pull requests are always welcome!
