The following are the spec and example files for serverclass.conf.
# Version 4.3.7 # # This file contains possible attributes and values for defining server classes to which # deployment clients can belong. These attributes and values specify what content a given server # class member will receive from the deployment server. # # To define server classes for this deployment server to use when deploying content to deployment # clients, place a serverclass.conf in $SPLUNK_HOME/etc/system/local/. # For examples, see serverclass.conf.example. You must restart Splunk for changes to this file # to take effect. # # To learn more about configuration files (including precedence) please see the documentation # located at http://docs.splunk.com/Documentation/Splunk/latest/Admin/Aboutconfigurationfiles #*************************************************************************** # Configure the server classes that are used by a deployment server instance. # # Server classes are essentially categories. They use filters to control what # clients they apply to, contain a set of applications, and may define # deployment server behavior for the management of those applications. The # filters can be based on dns name, ip address, build number of client # machines, platform, and so-called clientName tag strings. # If a target machine matches the filter, then the apps and configuration # content that make up the server class will be deployed to it. # # Property inheritance # Stanzas in serverclass.conf go from general to more specific, in the following order: # [serverClass] -> [serverClass:<name>] -> [serverClass:<scname>:app:<appname>] # # Some properties defined at a general level (say [serverClass]) can be # overridden by the more specific stanzas as it applies to them. All inheritable # properties are marked as such. #*************************************************************************** # Global stanza that defines properties for all server classes. [global] repositoryLocation = <path> * The repository of applications on the server machine. * Can be overridden at the serverClass level. * Defaults to $SPLUNK_HOME/etc/deployment-apps targetRepositoryLocation = <path> * The location on the deployment client to install the apps and configuration content defined for this server class. * If this value is unset, or set empty, the repositoryLocation path is used. * Useful only for complex (for example, tiered) deployment strategies. * Defaults to $SPLUNK_HOME/etc/apps, the live configuration directory for a Splunk instance. tmpFolder = <path> * Working folder used by deployment server. * Defaults to $SPLUNK_HOME/var/run/tmp continueMatching = true | false * Controls how configuration is layered across classes and server-specific settings. * If true, configuration lookups continue matching server classes, beyond the first match. * If false, only the first match will be used. * A serverClass can override this property and stop the matching. * Matching is done in the order that server classes are defined. * Can be overridden at the serverClass level. * Defaults to true endpoint = <URL template string> * The endpoint from which content can be downloaded by a deployment client. The deployment client knows how to substitute the values of the variables in the URL. * Any custom URL can also be supplied here as long as it uses the specified variables. * This attribute does not need to be specified unless you have very specific need, for example: to acquire deployment application files from a third-party httpd, for extremely large environments. * Can be overridden at the serverClass level. * Defaults to $deploymentServerUri$/services/streams/deployment?name=$serverClassName$:$appName$ filterType = whitelist | blacklist * The whitelist setting indicates a filtering strategy that pulls in a subset: * Items are not considered to match the stanza by default. * Items that match any whitelist entry, and do not match any blacklist entry are considered to match the stanza. * Items that match any blacklist entry are not considered to match the stanza, regardless of whitelist. * The blacklist setting indicates a filtering strategy that rules out a subset: * Items are considered to match the stanza by default. * Items that match any blacklist entry, and do not match any whitelist entry are considered to not match the stanza. * Items that match any whitelist entry are considered to match the stanza. * More briefly: * whitelist: default no-match -> whitelists enable -> blacklists disable * blacklist: default match -> blacklists disable-> whitelists enable * Can be overridden at the serverClass level, and the serverClass:app level. * Defaults to whitelist whitelist.<n> = <clientName> | <ip address> | <hostname> blacklist.<n> = <clientName> | <ip address> | <hostname> * 'n' is a number starting at 0, and increasing by 1. Stop looking at the filter when 'n' breaks. * The value of this attribute is matched against several things in order: * Any clientName specified by the client in its deploymentclient.conf file * The ip address of the connected client * The hostname of the connected client as provided by reverse DNS lookup * The hostname of the client as provided by the client * All of these can be used with wildcards. * will match any sequence of characters. For example: * Match an network range: 10.1.1.* * Match a domain: *.splunk.com * These patterns are PCRE regular expressions with the additional mappings: * '.' is mapped to '\.' * '*' is mapped to '.*' * Can be overridden at the serverClass level, and the serverClass:app level. * There are no whitelist or blacklist entries by default. # Note: Overriding one type of filter (whitelist/blacklist) causes the other to # the overridden too. It is important to note that if you are overriding the # whitelist, the blacklist will not be inherited from the parent - you must # provide one in the stanza. # Example of when filterType is whitelist # whitelist.0=*.splunk.com # blacklist.0=printer.splunk.com # blacklist.1=scanner.splunk.com # This will cause all hosts in splunk.com, except 'printer' and 'scanner' to match this server class. # Example of when filterType is blacklist # blacklist.0=* # whitelist.0=*.web.splunk.com # whitelist.1=*.linux.splunk.com # This will cause only the 'web' and 'linux' hosts to match the server class. No other hosts will match. # client machineTypes can also be used to match clients. # This setting lets you use the hardware type of the deployment client as a filter. # This filter will be used only if a client could not be matched using the whitelist/blacklist filter. # The value for machineTypes is a specific string that is designated by the hardware platform itself. # The method for finding this string on the client itself will vary by platform, but if the deployment client # is already connected to the deployment server, you can determine what this string is by using this # Splunk CLI command on the deployment server: # <code>./splunk list deploy-clients</code> # This will return a value for <code>utsname</code> that you can use to # specify <code>machineTypes</code>. machineTypes = <comma separated list> * This setting is deprecated. Use machineTypesFilter instead. If used, it will continue to work. * Not used unless specified. * Match any of the machine types in the comma-delimited list. * Commonly used machine types: linux-x86_64, windows-intel, linux-i686, freebsd-i386, darwin-i386, sunos-sun4u * This filter is used in boolean OR logic with white/blacklist filters. Clients which match the white/blacklist are included, and clients which match the machineTypes filter are included. This means a system which matches either rule will be considered to match. * In other words, the match is a union of the matches for the white/blacklist and the matches for machineTypes. * Be sure to include the 's' at the end of "machineTypes" * This filter can be overridden at the serverClass and serverClass:app levels. * This value is unset by default. machineTypesFilter = <comma separated list> * Not used unless specified. * Matches any of the machine types in the comma-delimited list. * Commonly used machine types: linux-x86_64, windows-intel, linux-i686, freebsd-i386, darwin-i386, sunos-sun4u * This filter is used in in boolean AND logic with white/blacklist filters. Only clients which match the white/blacklist AND which match this maachineTypesFilter will be included. * In other words, the match is an intersection of the matches for the white/blacklist and the matches for MachineTypesFilter. * This filter can be overridden at the serverClass and serverClass:app levels. * This filter is unset by default. * If both the machineTypes and machineTypesFilter attributes are specified, machineTypes is ignored. restartSplunkWeb = True | False * If True, restart SplunkWeb on the client when a member app or directly configured app is updated. * Can be overridden at the serverClass level, and the serverClass:app level. * Defaults to False restartSplunkd = True | False * If True, restart splunkd on the client when a member app or directly configured app is updated. * Can be overridden at the serverClass level, and the serverClass:app level. * Defaults to False stateOnClient = enabled | disabled | noop * For enabled, set the application state to enabled on the client, regardless of state on the deployment server. * For disable, set the application state to disabled on the client, regardless of state on the deployment server. * For noop, the state on the client will be the same as on the deployment server. * Can be overridden at the serverClass level, and the serverClass:app level. * Defaults to enabled. [serverClass:<serverClassName>] * This stanza defines a server class. A serverClass is a collection of applications. * serverClassName is a unique name that is assigned to this serverClass. * A serverClass can override all inheritable properties from the [serverClass] stanza. # # NOTE: # the following keys listed below are all described in detail in the # [global] section above, but can be used with serverClass stanza to # override the global setting # continueMatching = true | false endpoint = <URL template string> filterType = whitelist | blacklist whitelist.<n> = <clientName> | <ip address> | <hostname> blacklist.<n> = <clientName> | <ip address> | <hostname> machineTypes = <comma separated list> machineTypesFilter = <comma separated list> restartSplunkWeb = True | False restartSplunkd = True | False stateOnClient = enabled | disabled | noop repositoryLocation = <path> [serverClass:<server class name>:app:<app name>] * This stanza adds an application that exists in repositoryLocation to the server class. * server class name - the server class to which this content should be added. * app name can be '*' or the name of an app: * The value '*' refers to all content in the repositoryLocation, adding it to this serverClass. '*' stanzas cannot be mixed with named stanzas. * Other values 'someAppName' explicitly adds the app/configuration content to a server class. Typically apps are named by the folders that contain them. * Important note on matching: A server class must be matched before content belonging to the server class will be matched by the system. appFile=<file name> * In cases where an appName is different from the file or directory name, you can use this parameter to specify the file name. Supported formats are: app directories, .tar or .tgz files.
