The following are the spec and example files for
Version 7.3.4 This file maintains the state of a given app in Splunk Enterprise. It may also be used to customize certain aspects of an app. There is no global, default app.conf. Instead, an app.conf may exist in each app in Splunk Enterprise. You must restart Splunk Enterprise to reload manual changes to app.conf. To learn more about configuration files (including precedence) please see the documentation located at http://docs.splunk.com/Documentation/Splunk/latest/Admin/Aboutconfigurationfiles Settings for how an app appears in Launcher (and online on Splunkbase)
email = <e-mail> company = <company-name>
group = <group-name> name = <app-name> version = <version-number>
global setting remote_tab = <bool> * Set whether the Launcher interface will connect to apps.splunk.com. * This setting only applies to the Launcher app and should be not set in any other app * Defaults to true. per-application settings version = <version string> * Version numbers are a number followed by a sequence of dots and numbers. * Version numbers for releases should use three digits. * Pre-release versions can append a single-word suffix like "beta" or "preview." * Pre-release designations should use lower case and no spaces. * Examples: * 1.2.0 * 3.2.1 * 11.0.34 * 2.0beta * 1.3beta2 * 1.0preview description = <string> * Short explanatory string displayed underneath the app's title in Launcher. * Descriptions should be 200 characters or less because most users won't read long descriptions! author = <name> * For apps you intend to post to Splunkbase, enter the username of your splunk.com account. * For internal-use-only apps, include your full name and/or contact info (e.g. email). Your app can include an icon which will show up next to your app in Launcher and on Splunkbase. You can also include a screenshot, which will show up on Splunkbase when the user views info about your app before downloading it. You do not need to include an icon, but if you do, icon file names must end with "Icon" before the file extension, and the "I" must be capitalized. For example, "mynewIcon.png". Screenshots are optional. There is no setting in app.conf for these images. Splunk Web places files you upload into the <app_directory>/appserver/static directory. These images will not appear in your app. Move or place icon images to the <app_directory>/static directory. Move or place screenshot images to the <app_directory>/default/static directory. Launcher and Splunkbase will automatically detect the images. For example: <app_directory>/static/appIcon.png (the capital "I" is required!) <app_directory>/default/static/screenshot.png An icon image must be a 36px by 36px PNG file. An app screenshot must be 623px by 350px PNG file. [package] defines upgrade-related metadata, and will be used in future versions of Splunk Enterprise to streamline app upgrades.
id = <appid> * id should be omitted for internal-use-only apps which are not intended to be uploaded to Splunkbase * id is required for all new apps uploaded to Splunkbase. Future versions of Splunk Enterprise will use appid to correlate locally-installed apps and the same app on Splunkbase (e.g. to notify users about app updates) * id must be the same as the folder name in which your app lives in $SPLUNK_HOME/etc/apps * id must adhere to cross-platform folder-name restrictions: * must contain only letters, numbers, "." (dot), and "_" (underscore) characters * must not end with a dot character * must not be any of the following names: CON, PRN, AUX, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, LPT9 check_for_updates = <bool> * Set whether Splunk Enterprise should check Splunkbase for updates to this app. * Defaults to true. Set install settings for this app
state = disabled | enabled * Set whether app is disabled or enabled. * If an app is disabled, its configs are ignored. * Defaults to enabled. state_change_requires_restart = true | false * Set whether changing an app's state ALWAYS requires a restart of Splunk Enterprise. * State changes include enabling or disabling an app. * When set to true, changing an app's state always requires a restart. * When set to false, modifying an app's state may or may not require a restart depending on what the app contains. This setting cannot be used to avoid all restart requirements! * Defaults to false. is_configured = true | false * Stores indication of whether the application's custom setup has been performed * Defaults to false build = <integer> * Required. * Must be a positive integer. * Increment this whenever you change files in appserver/static. * Every release must change both "version" and "build" settings. * Ensures browsers don't use cached copies of old static files in new versions of your app. * Build is a single integer, unlike version which can be a complex string like 1.5.18. allows_disable = true | false * Set whether an app allows itself to be disabled. * Defaults to true. install_source_checksum = <string> * Records a checksum of the tarball from which a given app was installed. * Splunk Enterprise will automatically populate this value upon install. * You should *not* set this value explicitly within your app! install_source_local_checksum = <string> * Records a checksum of the tarball from which a given app's local configuration * was installed. Splunk Enterprise will automatically populate this value upon * install. You should *not* set this value explicitly within your app! Handle reloading of custom .conf files (4.2+ versions only)
reload.<conf_file_name> = [ simple | rest_endpoints | access_endpoints <handler_url> | http_get <handler_url> | http_post <handler_url> ] * Splunk Enterprise will reload app configuration after every app-state change: install, update, enable, and disable. * If your app does not use a custom config file (e.g. myconffile.conf) then it won't need a [triggers] stanza, because $SPLUNK_HOME/etc/system/default/app.conf already includes a [triggers] stanza which automatically reloads config files normally used by Splunk Enterprise. * If your app uses a custom config file (e.g. myconffile.conf) and you want to avoid unnecessary Splunk Enterprise restarts, you'll need to add a reload value in the [triggers] stanza. * If you don't include [triggers] settings and your app uses a custom config file, a Splunk Enterprise restart will be required after every state change. * Specifying "simple" implies that Splunk Enterprise will take no special action to reload your custom conf file. * Specify "access_endpoints" and a URL to a REST endpoint, and Splunk Enterprise will call its _reload() method at every app state change. * Specify "http_get" and a URL to a REST endpoint, and Splunk Enterprise will simulate an HTTP GET request against this URL at every app state change. * Specify "http_post" and a URL to a REST endpoint, and Splunk Enterprise will simulate an HTTP POST request against this URL at every app state change. * "rest_endpoints" is reserved for Splunk Enterprise internal use for reloading restmap.conf. * Examples: [triggers] Do not force a restart of Splunk Enterprise for state changes of MyApp Do not run special code to tell MyApp to reload myconffile.conf Apps with custom config files will usually pick this option reload.myconffile = simple Do not force a restart of Splunk Enterprise for state changes of MyApp. Splunk Enterprise calls the /admin/myendpoint/_reload method in my custom EAI handler. Use this advanced option only if MyApp requires custom code to reload its configuration when its state changes reload.myotherconffile = access_endpoints /admin/myendpoint
deployer_lookups_push_mode = preserve_lookups | always_preserve | always_overwrite * Determines the deployer_lookups_push_mode for the 'splunk apply shcluster-bundle' command. * If set to preserve_lookups, the 'splunk apply shcluster-bundle' command honors the '-preserve-lookups' option as it appears on the command line. If '-preserve-lookups' is flagged as "true", then lookup tables for this app are preserved. Otherwise, lookup tables are overwritten. * If set to always_preserve, the 'splunk apply shcluster-bundle' command ignores the '-preserve-lookups' option as it appears on the command line and lookup tables for this app are always preserved. * If set to always_overwrite, the 'splunk apply shcluster-bundle' command ignores the '-preserve-lookups' option as it appears on the command line and lookup tables for this app are always overwritten. * Default: preserve_lookups deployer_push_mode = full | merge_to_default | local_only | default_only * full: This option bundles all of the app's contents located in default/, local/, users/<app>/, and other app subdirs. It then pushes the bundle to the members. When applying the bundle on a member, the non-local and non-user configurations from the deployer's app folder are copied to the member's app folder, overwriting existing contents. Local and user configurations are merged with the corresponding folders on the member, such that member configuration takes precedence. This option should not be used for built-in apps, as overwriting the member's built-in apps may result in adverse behavior. * merge_to_default: This option merges the local and default folders into the default folder and pushes the merged app to the members. When applying the bundle on a member, the default configuration on the member is overwritten. User configurations are copied and merged with the user folder on the member, such that the existing configuration on the member takes precedence. In versions 7.2 and prior, this was the only behavior. This is the default mode if deployer_push_mode is not specified for an app, except for built-in apps, which default to local_only. * local_only: This option bundles the app's local directory (and its metadata) and pushes it to the cluster. When applying the bundle to a member, the local configuration from the deployer is merged with the local configuration on the member, such that the member's existing configuration takes precedence. Use this option to push the local configuration of built-in apps, such as search. If used to push an app that relies on non-local content (such as default/ or bin/), these contents must already exist on the member. * default_only: This option bundles all of the configuration files except for local and users/<app>/. When applying the bundle on a member, the contents in the member's default folder are overwritten. Set UI-specific settings for this app
is_visible = true | false * Indicates if this app should be visible/navigable as a UI app * Apps require at least 1 view to be available from the UI show_in_nav = true | false * Indicates if this app should be shown in global app dropdown is_manageable = true | false * Support for this setting has been removed. It no longer has any effect. label = <string> * Defines the name of the app shown in the Splunk Enterprise GUI and Launcher * Recommended length between 5 and 80 characters. * Must not include "Splunk For" prefix. * Label is required. * Examples of good labels: IMAP Monitor SQL Server Integration Services FISMA Compliance docs_section_override = <string> * Defines override for auto-generated app-specific documentation links * If not specified, app-specific documentation link will include [<app-name>:<app-version>] * If specified, app-specific documentation link will include [<docs_section_override>] * This only applies to apps with documentation on the Splunk documentation site attribution_link = <string> * URL that users can visit to find third-party software credits and attributions for assets the app uses. * External links must start with http:// or https://. * Values that do not start with http:// or https:// will be interpreted as Quickdraw "location" strings * and translated to internal documentation references. setup_view = <string> * Optional setting * Defines custom setup view found within /data/ui/views REST endpoint * If not specified, default to setup.xml Credential-verification scripting (4.2+ versions only) Credential entries are superseded by passwords.conf from 6.3 onwards. While the entries here are still honored post-6.3, updates to these will occur in passwords.conf which will shadow any values present here.
verify_script = <string> * Optional setting. * Command line to invoke to verify credentials used for this app. * For scripts, the command line should include both the interpreter and the script for it to run. * Example: "$SPLUNK_HOME/bin/python" "$SPLUNK_HOME/etc/apps/<myapp>/bin/$MY_SCRIPT" * The invoked program is communicated with over standard in / standard out via the same protocol as splunk scripted auth. * Paths incorporating variable expansion or explicit spaces must be quoted. * For example, a path including $SPLUNK_HOME should be quoted, as likely will expand to C:\Program Files\Splunk
password = <password> * Password that corresponds to the given username for the given realm. Note that realm is optional * The password can be in clear text, however when saved from splunkd the password will always be encrypted diag app extensions, 6.4+ only
extension_script = <filename> * Setting this variable declares that this app will put additional information into the troubleshooting & support oriented output of the 'splunk diag' command. * Must be a python script. * Must be a simple filename, with no directory separators. * The script must exist in the 'bin' sub-directory in the app. * Full discussion of the interface is located on the Developer portal. See http://dev.splunk.com/view/SP-CAAAE8H * Defaults to unset, no app-specific data collection will occur. data_limit = <positive integer>[b|kb|MB|GB] * Defines a soft-ceiling for the amount of uncompressed data that should be added to the diag by the app extension. * Large diags damage the main functionality of the tool by creating data blobs too large to copy around or upload. * Use this setting to ensure that your extension script does not accidentally produce far too much data. * Once data produced by this app extension reaches the limit, diag will not add any further files on behalf of the extension. * After diag has finished adding a file which goes over this limit, all further files will not be added. * Must be a positive number followed by a size suffix. * Valid suffixes: b: bytes, kb: kilobytes, mb: megabytes, gb: gigabytes * Suffixes are case insensitive. * Defaults to 100MB. Other diag settings default_gather_lookups = <filename> [, <filename> ...] * Setting this variable declares that the app contains lookups which should always be gathered by diag (by default). * Essentially, if there are lookups which are useful for troubleshooting an app, and will never contain sensitive (user) data, they can be added to this list, and they will appear in generated diags for use when troubleshooting the app from customer diags. * Any files in lookup dirs which are not listed here are not gathered by default; this can be overridden with the diag flag --include-lookups * This setting is new in Splunk Enterprise/Light version 6.5. Older versions gather all lookups by default. * This does not override the size-ceiling on files in etc. Large lookups will still be excluded, unless the etc-filesize-limit is raised/disabled. * This controls only files in the same app directory as this conf file. For example, if you have an app directory in etc/slave-apps (index clustering), this setting must appear in etc/slave-apps/appname/default/app.conf or local/app.conf * Additional lists can be created with default_gather_lookups-classname = ... * Defaults to unset.
