NAME

drbd-reactor.prometheus — drbd-reactor prometheus plugin

DESCRIPTION

drbd-reactor.prometheus is the prometheus plugin for drbd-reactor(1).

This plugin provides a prometheus compatible http endpoint serving DRBD metrics.

METRICS

• drbdreactor_up gauge: Boolean indicating whether or not drbdreactor is running. Always 1
• drbd_kernel_version gauge: Version of the loaded DRBD kernel module and DRBD utils
• drbd_connection_apinflight_bytes gauge: Number of application requests in flight (not completed)
• drbd_connection_congested gauge: Boolean whether the TCP send buffer of the data connection is more than 80% filled
• drbd_connection_rsinflight_bytes gauge: Number of resync requests in flight
• drbd_connection_state gauge: DRBD connection state
• drbd_device_alsuspended gauge: Boolean whether the Activity-Log is suspended
• drbd_device_alwrites_total counter: Number of updates of the activity log area of the meta data
• drbd_device_bmwrites_total counter: Number of updates of the bitmap area of the meta data
• drbd_device_client gauge: Boolean whether this device is a client (i.e., intentional diskless)
• drbd_device_lowerpending gauge: Number of open requests to the local I/O sub-system issued by DRBD
• drbd_device_quorum gauge: Boolean if this device has DRBD quorum
• drbd_device_read_bytes_total counter: Net data read from local hard disk
• drbd_device_size_bytes gauge: Device size in bytes
• drbd_device_state gauge: DRBD device state
• drbd_device_unintentionaldiskless gauge: Boolean whether the devices is unintentional diskless
• drbd_device_upperpending gauge: Number of block I/O requests forwarded to DRBD, but not yet answered by DRBD.
• drbd_device_written_bytes_total counter: Net data written on local disk
• drbd_peerdevice_outofsync_bytes gauge: Number of bytes currently out of sync with this peer, according to the bitmap that DRBD has for it
• drbd_peerdevice_sent_bytes: Number of bytes currently sent to this peer
• drbd_peerdevice_received_bytes: Number of bytes currently received from this peer
• drbd_resource_maypromote gauge: Boolean whether the resource may be promoted to Primary
• drbd_resource_promotionscore gauge: The promotion score (higher is better) for the resource
• drbd_resource_resources gauge: Number of resources
• drbd_resource_role gauge: DRBD role of the resource
• drbd_resource_suspended gauge: Boolean whether the resource is suspended

EXAMPLES

Configure an exporter also generating enums on the standard port.

[[log]]
level = "debug"

# Enable a prometheus exporter
[[prometheus]]
enums = true
