凋谢 snmp 协定端口
信息等级：1 info 2 notice 3 warning(warn) 4 err(error) 5 crit 6 alert 7 emerg(panic) 越到前面，越重大
两个非凡等级，debug（谬误检测等级）与 none（不须要登录等级），须要做谬误检测或者疏忽掉某些服务信息时应用“.”代表比符号前面更高的等级（含该等级 ) 都被记录。如：mail.info 代表只有是 mail 的信息，而且改信息等级高于 info（含 info），都会被记录下来。“.=“代表所须要的等级就是前面接的等级，其它不要“.!”代表不等于，即除该等级外的其余等级都记录
syslog 的日志文件只有被编辑过，就无奈记录，须要重新启动 rsyslog 服务
