Intelligent Platform Management Interface (IPMI)

Plugin: freeipmi.plugin Module: freeipmi


"Monitor enterprise server sensor readings, event log entries, and hardware statuses to ensure reliable server operations."

The plugin uses open source library IPMImonitoring to communicate with sensors.

This collector is supported on all platforms.

This collector supports collecting metrics from multiple instances of this integration, including remote instances.

The plugin needs setuid.

Default Behavior


This integration doesn't support auto-detection.


The default configuration for this integration does not impose any limits on data collection.

Performance Impact

Linux kernel module for IPMI can create big overhead.


Metrics grouped by scope.

The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.

The plugin does a speed test when it starts, to find out the duration needed by the IPMI processor to respond. Depending on the speed of your IPMI processor, charts may need several seconds to show up on the dashboard.

Per Intelligent Platform Management Interface (IPMI) instance

These metrics refer to the entire monitored application.

This scope has no labels.

Install freeipmi.plugin

When using our official DEB/RPM packages, the FreeIPMI plugin is included in a separate package named netdata-plugin-freeipmi which needs to be manually installed using your system package manager. It is not installed automatically due to the large number of dependencies it requires.

When using a static build of Netdata, the FreeIPMI plugin will be included and installed automatically, though you will still need to have FreeIPMI installed on your system to be able to use the plugin.

When using a local build of Netdata, you need to ensure that the FreeIPMI development packages (typically called libipmimonitoring-dev, libipmimonitoring-devel, or freeipmi-devel) are installed when building Netdata.

Preliminary actions

If you have not previously used IPMI on your system, you will probably need to run the ipmimonitoring command as root to initialize IPMI settings so that the Netdata plugin works correctly. It should return information about available sensors on the system.



The configuration file name for this integration is netdata.conf. Configuration for this specific integration is located in the [plugin:freeipmi] section within that file.

The file format is a modified INI syntax. The general structure is:

option1 = some value
option2 = some other value

option3 = some third value

You can edit the configuration file using the edit-config script from the Netdata config directory.

cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config netdata.conf


The configuration is set using command line options:

# netdata.conf
command options = opt1 opt2 ... optN

Decrease data collection frequency

Basic example decreasing data collection frequency. The minimum update every is 5 (enforced internally by the plugin). IPMI is slow and CPU hungry. So, once every 5 seconds is pretty acceptable.

update every = 10

Disable SEL collection

Append to command options = the options you need.

command options = no-sel

Ignore specific sensors

Specific sensor IDs can be excluded from freeipmi tools by editing /etc/freeipmi/freeipmi.conf and setting the IDs to be ignored at ipmi-sensors-exclude-record-ids.

However this file is not used by libipmimonitoring (the library used by Netdata's freeipmi.plugin).

To find the IDs to ignore, run the command ipmimonitoring. The first column is the wanted ID:

ID | Name | Type | State | Reading | Units | Event 1 | Ambient Temp | Temperature | Nominal | 26.00 | C | 'OK' 2 | Altitude | Other Units Based Sensor | Nominal | 480.00 | ft | 'OK' 3 | Avg Power | Current | Nominal | 100.00 | W | 'OK' 4 | Planar 3.3V | Voltage | Nominal | 3.29 | V | 'OK' 5 | Planar 5V | Voltage | Nominal | 4.90 | V | 'OK' 6 | Planar 12V | Voltage | Nominal | 11.99 | V | 'OK' 7 | Planar VBAT | Voltage | Nominal | 2.95 | V | 'OK' 8 | Fan 1A Tach | Fan | Nominal | 3132.00 | RPM | 'OK' 9 | Fan 1B Tach | Fan | Nominal | 2150.00 | RPM | 'OK' 10 | Fan 2A Tach | Fan | Nominal | 2494.00 | RPM | 'OK' 11 | Fan 2B Tach | Fan | Nominal | 1825.00 | RPM | 'OK' 12 | Fan 3A Tach | Fan | Nominal | 3538.00 | RPM | 'OK' 13 | Fan 3B Tach | Fan | Nominal | 2625.00 | RPM | 'OK' 14 | Fan 1 | Entity Presence | Nominal | N/A | N/A | 'Entity Present' 15 | Fan 2 | Entity Presence | Nominal | N/A | N/A | 'Entity Present' ...

freeipmi.plugin supports the option ignore that accepts a comma separated list of sensor IDs to ignore. To configure it set on netdata.conf:

command options = ignore 1,2,3,4,...
