- 
-Note that the usable range of PIDs for changing the log level of a single agent process is 1 to 65535. On systems with large PIDs, the <process type,N> target can be used for changing the log level of a single process. 
  
 Examples: ​ Examples: ​
   * increasing log level of all processes   * increasing log level of all processes
-  * increasing log level of the second ​listener process+  * increasing log level of the third listener process
   * increasing log level of process with PID 1234   * increasing log level of process with PID 1234
   * decreasing log level of all active check processes   * decreasing log level of all active check processes
