Exported metrics

Scrape meta data

These metrics provide data about the scrape itself:

  • ipmi_up{collector="<NAME>"} is 1 if the data for this collector could successfully be retrieved from the remote host, 0 otherwise. The following collectors are available and can be enabled or disabled in the config:
    • ipmi: collects IPMI sensor data. If it fails, sensor metrics (see below) will not be available
    • dcmi: collects DCMI data, currently only power consumption. If it fails, power consumption metrics (see below) will not be available
    • bmc: collects BMC details. If it fails, BMC info metrics (see below) will not be available
    • bmc-watchdog: collects status of the watchdog. If it fails, BMC watchdog metrics (see below) will not be available
    • chassis: collects the current chassis power state (on/off). If it fails, the chassis power state metric (see below) will not be available
    • sel: collects system event log (SEL) details. If it fails, SEL metrics (see below) will not be available
    • sel-events: collects metrics for user-defined events in system event log (SEL). If it fails, SEL entries metrics (see below) will not be available
    • sm-lan-mode: collects the "LAN mode" setting in the current BMC config. If it fails, the LAN mode metric (see below) will not be available
  • ipmi_scrape_duration_seconds is the amount of time it took to retrieve the data

BMC info

This metric is only provided if the bmc collector is enabled.

For some basic information, there is a constant metric ipmi_bmc_info with value 1 and labels providing the firmware revision and manufacturer as returned from the BMC, and the host system's firmware version (usually the BIOS version). Example:

ipmi_bmc_info{firmware_revision="1.66",manufacturer_id="Dell Inc. (674)",system_firmware_version="2.6.1"} 1

Note: some systems do not expose the system's firmware version, in which case it will be exported as "N/A".

BMC Watchdog

These metrics are only provided if the bmc-watchdog collector is enabled.

The metric ipmi_bmc_watchdog_timer_state shows whether the watchdog timer is currently running (1) or stopped (0).

The metric ipmi_bmc_watchdog_timer_use_state shows which timer use is currently active. Per freeipmi bmc-watchdog manual there are 5 uses. This metric will return 1 for only one of those and 0 for the rest.

ipmi_bmc_watchdog_timer_use_state{name="BIOS FRB2"} 1
ipmi_bmc_watchdog_timer_use_state{name="BIOS POST"} 0
ipmi_bmc_watchdog_timer_use_state{name="OEM"} 0
ipmi_bmc_watchdog_timer_use_state{name="OS LOAD"} 0
ipmi_bmc_watchdog_timer_use_state{name="SMS/OS"} 0

The metric ipmi_bmc_watchdog_logging_state shows whether the watchdog logging is enabled (1) or not (0). (Note: This is reversed in freeipmi where 0 enables logging and 1 disables it)

The metric ipmi_bmc_watchdog_timeout_action_state shows whether watchdog will take an action on timeout, and if so which one. Per freeipmi bmc-watchdog manual there are 3 actions. If no action is configured it will be reported as None.

ipmi_bmc_watchdog_timeout_action_state{action="Hard Reset"} 0
ipmi_bmc_watchdog_timeout_action_state{action="None"} 0
ipmi_bmc_watchdog_timeout_action_state{action="Power Cycle"} 1
ipmi_bmc_watchdog_timeout_action_state{action="Power Down"} 0

The metric ipmi_bmc_watchdog_timeout_action_state shows whether a pre-timeout interrupt is currently active and if so, which one. Per freeipmi bmc-watchdog manual there are 3 interrupts. If no interrupt is configured it will be reported as None.

ipmi_bmc_watchdog_pretimeout_interrupt_state{interrupt="Messaging Interrupt"} 0
ipmi_bmc_watchdog_pretimeout_interrupt_state{interrupt="NMI / Diagnostic Interrupt"} 0
ipmi_bmc_watchdog_pretimeout_interrupt_state{interrupt="None"} 1
ipmi_bmc_watchdog_pretimeout_interrupt_state{interrupt="SMI"} 0

The metric ipmi_bmc_watchdog_pretimeout_interval_seconds shows the current pre-timeout interval as measured in seconds.

The metric ipmi_bmc_watchdog_initial_countdown_seconds shows the configured countdown in seconds.

The metric ipmi_bmc_watchdog_current_countdown_seconds shows the current countdown in seconds.

Chassis Power State

This metric is only provided if the chassis collector is enabled.

The metric ipmi_chassis_power_state shows the current chassis power state of the machine. The value is 1 for power on, and 0 otherwise.

Power consumption

This metric is only provided if the dcmi collector is enabled.

The metric ipmi_dcmi_power_consumption_current_watts can be used to monitor the live power consumption of the machine in Watts. If in doubt, this metric should be used over any of the sensor data (see below), even if their name might suggest that they measure the same thing. This metric has no labels.

System event log (SEL) info

These metrics are only provided if the sel collector is enabled (it isn't by default).

The metric ipmi_sel_entries_count contains the current number of entries in the SEL. It is a gauge, as the SEL can be cleared at any time. This metric has no labels.

The metric ipmi_sel_free_space_bytes contains the current number of free space for new SEL entries, in bytes. This metric has no labels.

System event log (SEL) entries metrics

These metrics are only provided if the sel-events collector is enabled (it isn't by default).

For each event specified in the configuration file (sel_events field), will be generated metrics containing the number of such events and the timestamp of their last occurrence. Example:

ipmi_sel_events_count_by_name{name="my_custom_event_from_config"} 77
ipmi_sel_events_latest_timestamp{name="my_custom_event_from_config"} 1.703613275e+09

also next aggregated metrics will be exported:

ipmi_sel_events_count_by_state{state="Nominal"} 10
ipmi_sel_events_count_by_state{state="Warning"} 5

Supermicro LAN mode setting

This metric is only provided if the sm-lan-mode collector is enabled (it isn't by default).

NOTE: This is a vendor-specific collector, it will only work on Supermicro hardware, possibly even only on some Supermicro systems.

NOTE: Retrieving this setting requires setting privilege: "admin" in the config.

See e.g. https://www.supermicro.com/support/faqs/faq.cfm?faq=28159

The metric ipmi_config_lan_mode contains the value for the current "LAN mode" setting (see link above): 0 for "dedicated", 1 for "shared", and 2 for "failover".

Sensors

These metrics are only provided if the ipmi collector is enabled.

IPMI sensors in general have one or two distinct pieces of information that are of interest: a value and/or a state. The exporter always exports both, even if the value is NaN or the state non-sensical. This is so one can still always find the metrics to avoid ending up in a situation where one is looking for e.g. the value of a sensor that is in a critical state, but can't find it and assume this to be a problem.

The state of a sensor can be one of nominal, warning, critical, or N/A, reflected by the metric values 0, 1, 2, and NaN respectively. Think of this as a kind of severity.

For sensors with known semantics (i.e. units), corresponding specific metrics are exported. For everything else, generic metrics are exported.

Temperature sensors

Temperature sensors measure a temperature in degrees Celsius and their state usually reflects the temperature going above the vendor-recommended value. For each temperature sensor, two metrics are exported (state and value), using the sensor ID and the sensor name as labels. Example:

ipmi_temperature_celsius{id="18",name="Inlet Temp"} 24
ipmi_temperature_state{id="18",name="Inlet Temp"} 0

Fan speed sensors

Fan speed sensors measure fan speed in rotations per minute (RPM) or as a percentage of the maximum speed, and their state usually reflects the speed being to low, indicating the fan might be broken. For each fan speed sensor, two metrics are exported (state and value), using the sensor ID and the sensor name as labels. Example:

ipmi_fan_speed_rpm{id="12",name="Fan1A"} 4560
ipmi_fan_speed_state{id="12",name="Fan1A"} 0

or, for a percentage based fan:

ipmi_fan_speed_ratio{id="58",name="Fan 1 DutyCycle"} 0.2195
ipmi_fan_speed_state{id="58",name="Fan 1 DutyCycle"} 0

Voltage sensors

Voltage sensors measure a voltage in Volts. For each voltage sensor, two metrics are exported (state and value), using the sensor ID and the sensor name as labels. Example:

ipmi_voltage_state{id="2416",name="12V"} 0
ipmi_voltage_volts{id="2416",name="12V"} 12

Current sensors

Current sensors measure a current in Amperes. For each current sensor, two metrics are exported (state and value), using the sensor ID and the sensor name as labels. Example:

ipmi_current_state{id="83",name="Current 1"} 0
ipmi_current_amperes{id="83",name="Current 1"} 0

Power sensors

Power sensors measure power in Watts. For each power sensor, two metrics are exported (state and value), using the sensor ID and the sensor name as labels. Example:

ipmi_power_state{id="90",name="Pwr Consumption"} 0
ipmi_power_watts{id="90",name="Pwr Consumption"} 70

Note that based on our observations, this may or may not be a reading reflecting the actual live power consumption. We recommend using the more explicit power consumption metrics for this.

Generic sensors

For all sensors that can not be classified, two generic metrics are exported, the state and the value. However, to provide a little more context, the sensor type is added as label (in addition to name and ID). Example:

ipmi_sensor_state{id="139",name="Power Cable",type="Cable/Interconnect"} 0
ipmi_sensor_value{id="139",name="Power Cable",type="Cable/Interconnect"} NaN
