My team is interested in setting up a File System Check service monitor for a single file system path and its sub directories, /usr/local.
It seems the File System monitor applies to all the file systems on the host. How would I accomplish this monitor for only the specified path? (/usr/local)?
You are correct; the File System Capacity monitor only applies to file systems.The File and Directory plugin monitor will report on the size of specific files but not the who directory. To accomplish your goal, you will need to create a custom script that runs a command similar to `du | tail -1`.
