The cluster periodically collects hardware sensor information from hosts through the IPMI interface, so that alerts can be generated promptly to notify the user when anomalies are detected. If IPMI is not properly configured on a host, hardware sensor monitoring will not function normally.
IPMI info of the following { .labels.count } hosts is invalid or not configured: { .labels.invalid_account_hostname}.
The hardware sensor monitoring on the host (such as CPU temperature and fan speed) becomes non-functional, which may result in hardware failures (such as power supply failures) not being detected in time.
The IPMI account information for the host is not correctly configured.
If the cluster management network and the IPMI network are not interconnected, and hardware sensor data collection is not required, you can choose to disable this alert.
If the host has not been configured with IPMI information, go to the cluster's Settings > IPMI information page and configure the IPMI information for the host.
If the host has IPMI information configured but the alert is still triggered, run the following command on the host to verify the connection:
ipmitool -H <IP> -U '<user_name>' -P '<password>' -I lanplus user list
If the command does not return results correctly, troubleshoot the following based on the error messages:
Ensure that the node can successfully ping the IPMI IP address and verify that port 623 is available.
Confirm whether the IPMI account has administrator access.
Confirm whether the IPMI account password is entered correctly.
Check whether IPMI or DCMI over LAN is enabled in the server configuration.
If some nodes of the same server model batch cannot connect, confirm whether their BMC firmware versions are consistent.
