Standalone app
Pre-built executables are available for Windows, macOS and Linux.
Running Butler as standalone, native app
Windows
Running standalone Butler on Windows Server 2016 looks like this:
PS C:\tools\butler> .\butler.exe
Usage: butler [options]
Butler gives superpowers to client-managed Qlik Sense Enterprise on Windows!
Advanced reload failure alerts, task scheduler, key-value store, file system access and much more.
Options:
-V, --version output the version number
-c, --configfile <file> path to config file
-l, --loglevel <level> log level (choices: "error", "warn", "info", "verbose", "debug", "silly")
--new-relic-account-name <name...> New Relic account name. Used within Butler to differentiate between different target New Relic accounts
--new-relic-api-key <key...> insert API key to use with New Relic
--new-relic-account-id <id...> New Relic account ID
--test-email-address <address> send test email to this address. Used to verify email settings in the config file.
--test-email-from-address <address> send test email from this address. Only relevant when SMTP server allows from address to be set.
--no-qs-connection don't connect to Qlik Sense server at all. Run in isolated mode
--api-rate-limit set the API rate limit, per minute. Default is 100 calls/minute. Set to 0 to disable rate limiting.
-h, --help display help for command
PS C:\tools\butler>
Adding the --configfile option and pointing it to a valid config file gives Butler everything needed to start.
All other options are optional.

Windows services & process monitors
You can use the excellent Nssm tool to make Butler run as a Windows Service, with all the benefits that follow (can be monitored using operations tools, automatic start/restart etc).
A step-by-step tutorial for running Butler as a Windows service is available over at ptarmiganlabs.com.
macOS and Linux
Running the standalone Butler tool without any parameters gives you a help text that explains which commands and options are available:
➜ butler ./butler
Usage: butler [options]
Butler gives superpowers to client-managed Qlik Sense Enterprise on Windows!
Advanced reload failure alerts, task scheduler, key-value store, file system access and much more.
Options:
-V, --version output the version number
-c, --configfile <file> path to config file
-l, --loglevel <level> log level (choices: "error", "warn", "info", "verbose", "debug", "silly")
--new-relic-account-name <name...> New Relic account name. Used within Butler to differentiate between different target New Relic accounts
--new-relic-api-key <key...> insert API key to use with New Relic
--new-relic-account-id <id...> New Relic account ID
--test-email-address <address> send test email to this address. Used to verify email settings in the config file.
--test-email-from-address <address> send test email from this address. Only relevant when SMTP server allows from address to be set.
--no-qs-connection don't connect to Qlik Sense server at all. Run in isolated mode
--api-rate-limit set the API rate limit, per minute. Default is 100 calls/minute. Set to 0 to disable rate limiting.
-h, --help display help for command
➜ butler
The available options are exactly the same as for Windows.
Services & process monitors
The exact way of auto-starting apps when a computer boots varies between different versions of macOS and Linux.
If you want to do this Google is your friend.
That said, PM2 and Forever are two process monitors that both have been successfully tested with Butler. These tools bascially monitor what processes are running and restart them if they for some reason fail.
Command line options
Tip
Any option given on the command line will override the same setting in the config file
--version, -V
Shows Butler’s version number.
--configfile, -c
The --configfile option is a must-have as it’s the only way to tell the standalone Butler executable where to find its config file.
--loglevel, -l
The --loglevel option can be quite useful when you want to temporarily switch from the info level logging set in the config file, to a more detailed verbose or debug level logging while investigating some problem.
--new-relic-account-name
A list of New Relic account names to which data can be sent from Butler.
The arguments to this option consists of one or more strings enclosed in single or double quotes (depending on which operating system is used), separated by a space.
For example --new-relic-account-name "First NR account" "Second NR account".
Note that the same number of arguments must be passed to all the command line options dealing with New Relic accounts!
--new-relic-api-key
It’s always better to store sensitive information in environment variable than in config files.
For that reason it’s possible to provide the New Relic insert API keys (used when sending data to New Relic) via a command line option.
It’s then possible to pass in the New Relic API key via the command line rather than store it within the config file.
The arguments to this option consists of one or more strings enclosed in single or double quotes (depending on which operating system is used), separated by a space.
For example --new-relic-api-key "API key 1" "API key 2".
--new-relic-account-id
Similar to the --new-relic-api-key, the account ID(s) used with New Relic can be provided as a command line option.
The arguments to this option consists of one or more strings enclosed in single or double quotes (depending on which operating system is used), separated by a space.
For example --new-relic-account-id "account ID 1" "account ID 2".
--test-email-address
Used to send a test email to an email addresses. Can be used to confirm that the SMTP settings used when sending reload failed/aborted notification emails are working as intended.
Example: --test-email-address joe@company.com
--test-email-from-address
Some SMTP servers, for example GMail, require you to authenticate before any emails can be sent. The sender will then be the logged in/authenticated user.
When using a non-authenticating SMTP server (common in enterprises where access to the SMTP server is limited to the internal network) the sender email address (and optionally name) has to be specified manually.
Example: --test-email-from-address "User Anna <anna@company.com>"
--no-qs-connection
When running Butler in standalone mode it’s possible to disable the connection to the Qlik Sense server. This is used when Butler is executed to provide a Swagger/OpenAPI specification file for the Butler API, i.e. not for any production use-cases.
--api-rate-limit
The --api-rate-limit option can be used to set the REST API rate limit, per minute. Default is 100 calls/minute. Set to 0 to disable rate limiting.
