| Demonstrations of vfscount, the Linux eBPF/bcc version. | |
| This counts VFS calls, by tracing various kernel calls beginning with "vfs_" | |

| # ./vfscount | |
| Tracing... Ctrl-C to end. | |

| ffffffff811e6061 vfs_open 765 | |
| ffffffff811e7091 vfs_read 1852 | |
| This can be useful for workload characterization, to see what types of | |
| operations are in use. |
