 A list of core loggers and their purpose is defined within [the App Server schema](https://github.com/zowe/zlux-app-server/blob/c22105381e129bd999c47e838b424679eba26aa6/schemas/app-server-config.json#L401)
 Loggers, plugin loggers, and log levels (such as 5 for highest debugging, or 2 for default) are defined in detail in the [Logging document](../../extend/extend-desktop/mvd-logutility)
 
+Attributes within `components.app-server.logLevels` can be exact names of loggers, or can be pattern matching of multiple loggers.
+
+For example, to enable minimum debug verbosity of the auth logger of the server core ("_zsf.auth"), and to enable maximum verbosity logging of all plugins made by company foo ("com.foo"), you could set the YAML configuration as:
+
+```yaml
+components:
+  app-server:
+    logLevels:
+    - _zsf.auth: 3
+    - com.foo.*: 5

 # Advanced debugging for ZSS
 
 The Zowe YAML file section `components.zss.logLevels` controls the verbosity for every logger within the server.
 This includes core loggers, prefixed with `_zss`.
 
 A list of core loggers and their purpose is defined within [the ZSS schema](https://github.com/zowe/zss/blob/c85e374f3d7a4a9b93d6f8337d474f384135744b/schemas/zss-config.json#L235)
 
+Unlike the App Server, the `components.zss.logLevels` section cannot take pattern matching for attribute names. The attribute names must exactly match the name of a logger.
