Use ping to check connection statistics for a remote host.

Usage:

check_ping -H <host_address> -w <wrta>,<wpl>% -c <crta>,<cpl>%

[-p packets] [-t timeout] [-4|-6]

Options:

-h, --help

Print detailed help screen

-V, --version

Print version information

-4, --use-ipv4

Use IPv4 connection

-6, --use-ipv6

Use IPv6 connection

-H, --hostname=HOST

host to ping

-w, --warning=THRESHOLD

warning threshold pair

-c, --critical=THRESHOLD

critical threshold pair

-p, --packets=INTEGER

number of ICMP ECHO packets to send (Default: 5)

-L, --link

show HTML in the plugin output (obsoleted by urlize)

-t, --timeout=INTEGER

Seconds before connection times out (default: 10)

THRESHOLD is <rta>,<pl>% where <rta> is the round trip average travel

time (ms) which triggers a WARNING or CRITICAL state, and <pl> is the

percentage of packet loss to trigger an alarm state.

This plugin uses the ping command to probe the specified host for packet loss

(percentage) and round trip average (milliseconds). It can produce HTML output

linking to a traceroute CGI contributed by Ian Cass. The CGI can be found in

the contrib area of the downloads section at

用法：

Usage: check_ping -H <host_address> -w <wrta>,<wpl>% -c <crta>,<cpl>%

[-p packets] [-t timeout] [-L] [-4|-6]

具體如下：

-H     主機地址

-w     WARNING 警告狀態：   響應時間(毫秒)，丟包率 (%)   閥值

-c     CRITICAL 危險狀態：  響應時間(毫秒)，丟包率 (%)   閥值

-p     發送的包數       默認5個包

-t     超時時間         默認10秒

-4|-6                   使用ipv4|ipv6 地址     默認ipv4

示例：

復制代碼 代碼如下:

./check_ping -H 8.8.8.8 -w 200,20% -c 300,50% -p 3 -t 2

-H 目標主機

-w 延時200丟包20%

-c 延時300丟包50%

延時有3個范圍

1. 延時 小于 200

2. 延時 在 200 - 300 范圍內

3. 延時 大于 300

小于則輸出 OK 正常

范圍內則輸出 WARNING 警告

大于則輸出 CRITICAL 宕機

1、OK 正常

復制代碼 代碼如下:

[root@204 plugins]# ./check_ping -H 8.8.8.8 -w 200,20% -c 300,50% -p 3 -t 2

PING OK - Packet loss = 0%, RTA = 96.45 ms|rta=96.449997ms;200.000000;300.000000;0.000000 pl=0%;20;50;0

2、WARNING 警告

復制代碼 代碼如下:

[root@204 plugins]# ./check_ping -H 8.8.8.8 -w 100,20% -c 200,50% -p 3 -t 2

PING WARNING - Packet loss = 0%, RTA = 106.00 ms|rta=106.003998ms;100.000000;200.000000;0.000000 pl=0%;20;50;0

3、CRITICAL 宕機

復制代碼 代碼如下:

[root@204 plugins]# ./check_ping -H 8.8.8.8 -w 50,20% -c 100,50% -p 3 -t 2

PING CRITICAL - Packet loss = 0%, RTA = 128.41 ms|rta=128.410995ms;50.000000;100.000000;0.000000 pl=0%;20;50;0
