# `bpf-map-info` Input Plugin

Collects metadata information on BPF maps loaded on the host.

## Configuration

```conf

# Fetch metadata metrics from BPF maps on the host.

[[inputs.bpf_map]]

  ## Optional Fields

  ## Size of map key in bytes.

  ##

  ## Corresponds to `key_size` field in `bpf_map_info`.

  key_size = true

  ## Size of map value in bytes.

  ##

  ## Corresponds to `value_size` field in `bpf_map_info`.

  value_size = true

  ## Max entries map can hold.

  ##

  ## Corresponds to `max_entries` field in `bpf_map_info`.

  max_entries = true

  ## Map flags used in loading.

  ##

  ## Corresponds to `map_flags` field in `bpf_map_info`.

  map_flags = true

```

## Metrics

These metrics are extracted from the `bpf_map_info` object.

- bpf_map

  - tags:

    - id

    - type

    - name

  - fields:

    - key_size (integer, bytes)

    - value_size (integer, bytes)

    - max_entries (integer, count)

    - map_flags (integer)

## Usage

Build binary:

```golang

go build -o bpf-map cmd/main.go

```

Execute binary:

```golang

sudo ./bpf-map -config plugin.conf

```
