Diamond-StorageCollectors

Note: Directory structure has been updated to match the new version of diamond collector

Various storage related diamond collectors for graphite.

## LvmCollector

Collects Lvm metrics in three set (pv, vg, lv). The format is .lvm.pv.[device].[metric]. For example:

.lvm.pv._dev_hdc.pv_size is the size of the /dev/hdc Phisical Volume

### Installation

1. Move the lvm directory to your collectors directory which should exist on /usr/local/share/diamond/collectors or /usr/share/diamond/collectors path depending on your installation.

2. Setup the LvmCollector.conf in your diamond collectors config directory (/etc/diamond/collectors)

    $ cat /etc/diamond/collectors/LvmCollector.conf
    enabled = True
    interval = 60
   

Configuration

Default config for the collector:

{
	'path': 'lvm',
	# Leave unset to publish all
	#name parameters are essentail don't remove them
	'publish': {
		'pv': ('pv_name', 'pv_uuid', 'pe_start', 'pv_size', 'pv_free', 'pv_used', 'pv_pe_count', 'pv_pe_alloc_count'),
		'vg': ('vg_fmt', 'vg_uuid', 'vg_name', 'vg_size', 'vg_free', 'vg_extent_size', 'vg_extent_count', 'vg_free_count', 'max_lv', 'max_pv', 'pv_count', 'lv_count', 'snap_count', 'vg_seqno'),
		'lv': ('vg_name', 'lv_uuid', 'lv_name', 'lv_major', 'lv_minor', 'lv_kernel_major', 'lv_kernel_minor', 'lv_kernel_read_ahead', 'lv_size', 'seg_count', 'origin_size', 'snap_percent'),
	},
	'identifiers': {
		'pv': ('pv_name',),
		'vg': ('vg_name',),
		'lv': ('vg_name', 'lv_name'),
	},
	'commands': {
		'pv': 'pvs',
		'vg': 'vgs',
		'lv': 'lvs',
	}
}
