Disk Usage
The disk input plugin, gathers the information about the disk throughput of the running system every certain interval of time and reports them.
The plugin supports the following configuration parameters:
Key | Description |
Interval_Sec | Polling interval (seconds). default: 1 |
Interval_NSec | Polling interval (nanosecond). default: 0 |
Dev_Name | Device name to limit the target. (e.g. sda). If not set, in_disk gathers information from all of disks and partitions. |
In order to get disk usage from your system, you can run the plugin from the command line or through the configuration file:
$ fluent-bit -i disk -o stdout

[OUTPUT]
Name stdout

Note: Total interval (sec) = Interval_Sec + (Interval_Nsec / 1000000000).
e.g. 1.5s = 1s + 500000000ns
