數據源: /proc/net/snmp; 採集方式：累計值，每10秒採集一次取差值； 指標：net.snmp.icmp (key: system);
Out Dest Unreachs: 發送的icmp目的不可達包總數, out_dest_unreachs/10 -> op/s;
In Dest Unreachs: 接收的icmp目的不可達包總數，in_dest_unreachs/10 -> op/s;
Out Echo Reps: 發送的icmp回顯應答包總數，out_echo_repos/10 -> op/s;
In Echo Reps: 接收的icmp回顯應答包總數，in_echo_repos/10 -> op/s;
Out Echos: 發送的icmp回顯請求包總數, out_echos/10 -> op/s;
In Echos: 接收的icmp回顯請求包總數，in_echos/10 -> op/s;
Out Time Excds: 發送的icmp超時包的個數，out_time_excds/10 -> op/s;
In Time Excds: 接收的icmp超時包的個數，in_time_excds/10 -> op/s;
