record id初始化

• sel-delete is enabled
  搜索/var/log/next_records，获取当前record id
  如果该文件不存在则创建该文件

• sel-delete is disabed
  搜索/var/log目录下,ipmi_sel开头的文件,找到最后一条记录获取record id

IPMI SEL接口

增加SEL Log

Method	Desc
IpmiSelAdd
IpmiSelAddOem

• send-to-logger is enabled

send to 'phosphor-logging' by dbus:
  xyz.openbmc_project.Logging /xyz/openbmc_project/logging xyz.openbmc_project.Logging.Create Create

• send-to-logger is disabled

send to systemd directly by 'sd_journal_send'

删除SEL Log

Method	Desc
Clear
IpmiSelDelete

• sel-delete is enabled

- 删除日志文件
- Reload rsyslog so it knows to start new log files
  org.freedesktop.systemd1 /org/freedesktop/systemd1 org.freedesktop.systemd1.Manager ReloadUnit rsyslog.service replace
- 重置/var/log/next_records

• sel-delete is disabed

- 删除日志文件
- Reload rsyslog so it knows to start new log files
  org.freedesktop.systemd1 /org/freedesktop/systemd1 org.freedesktop.systemd1.Manager ReloadUnit rsyslog.service replace
