Base Plugin

The base plugins uses the oshi library to get it's metrics.

Processor Extension

Reports the following metrics seen:

• system -CPU time (in ms) spend on system processes.
• user - CPU time (in ms) spend on user processes.
• nice - CPU time (in ms) spend on user processes running at lower priority.
• iowait - CPU time (in ms) spend waiting (for i/o).
• steal - CPU time (in ms) stolen by hypervisor and given to other virtual systems.
• irq - CPU time (in ms) spend by kernel on interrupt requests.
• softirq - CPU (in ms) time spend by kernel on soft interrupt requests.
• idle - CPU time (in ms) spend idling (doing nothing).
• busy - CPU time (in ms) spend working.

Memory Extension

Reports the following metrics (in bytes):

• available - Estimation of how much memory is available for starting new applications, without swapping.
• total - The total amount of (installed) memory.
• usage - Percentage of memory used out of the total amount of memory.
• paged - ...
• virtual - ...

Disk Extension

Metrics reported are:

• reads - The total number of bytes read.
• writes - The total number of bytes written.
• iotime - Time spent on IO in milliseconds.
• queue - Length of disk IO queue.

Filesystem Extension

Metrics

• free_bytes - Free bytes for filesystem.
• total_bytes - Total bytes for filesystem.
• free_inodes - Free inodes for filesystem.
• total_inodes - Total inodes for filesystem.

Configuration

[extension.base_filesystem]
enabled = true
interval = "10s"
exclude_type = [ "tmpfs", "ahafs" ]
exclude_mount = [ "/boot/efi" ]

Process Extension

Reports metrics on one or more running processes.

• mem_rss - Resident set memory in bytes.
• mem_vsz - Virtual memory in bytes.
• kernel_time - Time spent (in milliseconds) in kernel space.
• user_time - Time used (in milliseconds) in user space.
• read_bytes - Bytes read by process.
• write_bytes - Bytes written by process.
• files - Files currently open by process.
• threads - Running threads.
• user - User running the process.
• group - Group running the process
• prio - Process priority.

Configuration

The include option let's you specify what processes to report for.

[extension.base_process]
enabled = true # true or false
interval = "10s"
include = [ "java", "influxd", "grafana-server" ]
