-
-The `lenovo_dense_power` collector reads power from Lenovo Dense machines via `ipmitool` (`ipmitool raw ...`). This collector is known to only work on the following machines. Others are not supported, so use at your *OWN* risk:
-
-System                                    | Compatibility             | Power measured
---                                       | ---                       | ---
-Lenovo ThinkSystem SD650 V2/V3            | untested, but should work | node + riser1 + riser2
-Lenovo ThinkSystem SD650-N V2/ SD650-I V3 | untested, but should work | node + riser1 + riser2 + gpus
-Lenovo ThinkSystem SD665-N V3             | tested, known to work     | node + riser1 + riser2 + gpus
-
-To test if your system *may* be supported, you can run the following command *at your own risk*:
-
-```
-$ ipmitool raw 58 50 4 2 0 0 0
- c4 00 83 a9 cb d3 a2 03 df db 47 6a d8 01
-```
-
-Exactly 14 bytes should be returned.
-In case not or another error occurs your hardware is likely not supported.
-
-In addition, `ipmitool` typically require root to run.
-In order to run `cc-metric-collector` without root priviliges, you can enable `use_sudo`.
-Add a file like this in `/etc/sudoers.d/` to allow `cc-metric-collector` to run the required commands:
-
-```
-# Do not log the following sudo commands from monitoring, since this causes a lot of log spam.
-# However keep log_denied enabled, to detect failures
-Defaults: monitoring !log_allowed, !pam_session
-
-# Allow to use ipmitool for Lenovo power readings
-monitoring ALL = (root) NOPASSWD:/usr/bin/ipmitool raw 58 50 4 2 0 0 0

-## `lenovo_dense_power` collector
-
-```json
-  "megware_eureka": {
-    "u20_path": "/path/to/ipmitool",
-    "use_sudo": true
-  }
-```
-
-The `megware_eureka` collector reads power and other metrics from Megware Eureka machines via `u20`.
-If the u20 tool is available for your machines, it's possible that this collector is compatible.
-If you don't have access to u20, please contact your Megware sales person.
-
-You can test the collector compatibility by running the following command:
-
-```
-$ u20 values --read GET_MPS_POLL_VALUES
-```
-
-If this returns a JSON with energy, voltage and current readings, you're fine.
-
-In addition, `u20` typically requires root to run.
-In order to run `cc-metric-collector` without root priviliges, you can enable `use_sudo`.
-Add a file like this in `/etc/sudoers.d/` to allow `cc-metric-collector` to run the required commands:
-
-```
-# Do not log the following sudo commands from monitoring, since this causes a lot of log spam.
-# However keep log_denied enabled, to detect failures
-Defaults: monitoring !log_allowed, !pam_session
-
-# Allow to use u20 for Megware power readings
-monitoring ALL = (root) NOPASSWD:/usr/bin/u20 values --read GET_MPS_POLL_VALUES
-```
