以下是$ipmitool -sensor的输出，它们显示了所有DIMM信息。但FreeIPMI只有插件的DIMM信息。如何在C中使用FreeIPMI API获取所有内存DIMM信息？

关于内存信息，我知道DIMMA1，A2和B2不是插件，DIMMB1的温度是36.0度。

但没有关于DIMMA1，A2和B2的信息，因为它们不是插件。所以我追踪了impi-monitoring-sensor.c的代码。
if ((sensor_count = ipmi_monitoring_sensor_readings_by_record_id (ctx,
hostname,
ipmi_config,
sensor_reading_flags,
NULL, /* record_ids */
0, /* record_ids_length */
NULL,
NULL)) < 0)
和配置
static void
_init_ipmi_config (struct ipmi_monitoring_ipmi_config *ipmi_config)
{
assert (ipmi_config);
ipmi_config->driver_type = driver_type;
ipmi_config->disable_auto_probe = disable_auto_probe;
ipmi_config->driver_address = driver_address;
ipmi_config->register_spacing = register_spacing;
ipmi_config->driver_device = driver_device;
ipmi_config->protocol_version = protocol_version;
ipmi_config->username = username;
ipmi_config->password = password;
ipmi_config->k_g = k_g;
ipmi_config->k_g_len = k_g_len;
ipmi_config->privilege_level = privilege_level;
ipmi_config->authentication_type = authentication_type;
ipmi_config->cipher_suite_id = cipher_suite_id;
ipmi_config->session_timeout_len = session_timeout;
ipmi_config->retransmission_timeout_len = retransmission_timeout;
ipmi_config->workaround_flags = workaround_flags;
}
我可以假设主板有4个DIMM插槽，如果在FreeIPMI传感器输出中找不到它们，我猜它们不是插件。但是如何通过IPMI命令知道主板上的所有DIMM插槽？
答案 0 :(得分：0)
FreeIPMI维护者在这里。一般来说，FreeIPMI中的大多数工具都不会输出有关传感器的信息（如果它不可用＆＃34;）。 （在内部，它映射到我不会详细说明的各种事情。）无论可用性如何，默认情况下ipmitool会输出一些传感器信息。
根据您关于使用IPMI命令的问题。使用FreeIPMI的ipmi-sensors，您可以使用-v（或可能的-vv）查看剩余的DIMM。
根据关于API的标题中的问题，在libipmimonitoring API中，键标志为IPMI_MONITORING_SENSOR_READING_FLAGS_IGNORE_NON_INTERPRETABLE_SENSORS。在示例代码中查找它，您可能会看到该怎么做。
