smokeping 微信報警配置

1. 准備alert腳本，用來調用微信腳本

#!/bin/bash

alertname=$1
target=$2
losspattern=$3
rtt=$4
hostname=$5

smokename="hq_to_idc "
if [ "$losspattern" = "loss: 0%" ];
then
subject="Clear-${smokename}-Alert: $target host: ${hostname}"
else
subject="${smokename}Alert: ${target} – ${hostname}"
fi
echo "MTR Report for hostname: ${hostname}" > /tmp/mtr.txt
echo ""  >> /tmp/mtr.txt
echo "sudo mtr -n –report ${hostname} "
sudo /usr/sbin/mtr -n –report ${hostname} >> /tmp/mtr.txt
echo "" >> /tmp/mtr.txt
echo "Name of Alert: " $alertname >> /tmp/mtr.txt
echo "Target: " $target >> /tmp/mtr.txt
echo "Loss Pattern: " $losspattern >> /tmp/mtr.txt
echo "RTT Pattern: " $rtt >> /tmp/mtr.txt
echo "Hostname: " $hostname >> /tmp/mtr.txt
echo "" >> /tmp/mtr.txt
echo "Full mtr command is: sudo /usr/sbin/mtr -n –report ${hostname}" >> /tmp/mtr.txt
echo "subject: " $subject
if [ -s /tmp/mtr.txt ]; then
  /usrt/smokeping/weixin.sh "s" "s" "${subject}:${hostname}:$losspattern:$rtt:$target"
fi

准備微信報警代碼

#!/bin/bash
### script name weixin.sh
### send messages from weixin for zabbix monitor
### 000
### 000
### usage:   curl -s -G url 獲取acessToken
### curl --data url 傳送憑證調用企業號接口
### zabbix 會傳送三個參數給腳本，$1 是消息接收賬號，$2 報警標題， $3 報警內容

CropID=''
Secret=''
GURL="https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=$CropID&corpsecret=$Secret"
Gtoken=$(/usr/bin/curl -s -G $GURL | awk -F '"' '{print $4}')
now_time=$(date -d now)
now_timestamp=$(date -d "${now_time}" +%s)

function logMessageToFile(){
  echo "[ $1 ] - ["$(date "+%Y-%m-%d %H:%M:%S")"] - $2" >> $LOG_FILE
}

function create_tokenfile(){
echo "${now_time} > ${Gtoken}"  > ${token_file}
}

function get_Gtoken(){
GURL="https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=$CropID&corpsecret=$Secret"
Gtoken=$(/usr/bin/curl -s -G $GURL | awk -F '"' '{print $4}')
}

function check_token(){
        if [ -f "${token_file}" ]; then
                file_token=$(awk -F '>' '{print $2}' ${token_file})
                file_time=$(awk -F '>' '{print $1}'  ${token_file})
                file_timestamp=$(date -d "${file_time}" +%s)
                time_difference=$[${now_timestamp}-${file_timestamp}]
                if [ "${time_difference}" -gt "${options}" ]; then
                        get_Gtoken
                        create_tokenfile
                        logMessageToFile "INFO" "上次token是： ${file_token},到現在過了${time_difference} 秒, 新的token是：${Gtoken}"
                else
                        logMessageToFile "INFO"  "not need update the token, use old token ${file_token}  到現在過了${time_difference} 秒"
                        Gtoken=$(echo ${file_token})
                fi
        else
                get_Gtoken
                logMessageToFile "INFO" "the token_file : ${token_file} not exsits ,will create it . 到現在過了${time_difference} 秒"
                create_tokenfile
        fi

}


function body(){
        local int AppID=1                  # 企業號中的應用ID
        local UserID="@all"                  # 部門成員id，zabbix中定義的微信接受者
        local PartyID="1"                # 部門id，定義了范圍，組內成員都可接收到消息
        local Msg=$(echo "$@" | cut -d " " -f3-) # 過濾出zabbix中傳遞的第三個參數
        printf '{\n'
        printf '\t"touser":"'"$UserID"\"",\n"
        printf '\t"toparty":"'"$PartyID"\"",\n"
        printf '\t"msgtype": "text",'"\n"
        printf '\t"agentid":'$AppID\,"\n"
        printf '\t"text":{\n'
        printf '\t\t"content":"'"$Msg"\"
        printf '\n\t},\n'
        printf '\t"safe":"0"\n'
        printf '}\n'
}

check_token
#smokeping_alert=${1}-${2}-${3}-${4}-${5]
/usr/bin/curl --data-ascii "$(body $1 $2 $3)" $PURL

# smokeping 配置文件 config中需要修改的參數
# to 后面默認是 填寫 郵件 
# 如果 = 后面 跟上 | 代表執行用戶自己的腳本
# 腳本會讀入5或者6個參數：name-of-alert, target, loss-pattern, rtt-pattern, #     hostname,[raise]。
*** Alerts ***
#to = |/opt/smokeping/alert.sh
to =[e-mail]
from = [e-mail]

# 報警條件
+someloss
type = loss
# in percent
pattern = >0%,*12*,>0%,*12*,>0%
comment = loss 3 times  in a row
# 意思是  12次檢查中 出現了 3次丟包的情況

監控主機參數增加
 alerts = someloss

后續規則可以自己調整

2、特定主機發送到特定用戶

to 表示接受所有報警的郵箱，如果需要在特定的節點報警發送到特定的郵箱
則在該節點上增加alertee = [e-mail]即可。具體可以參看/opt/smokeping/lib/Smokeping.pm源碼，如下部分:

1. foreach my $addr (map {$_ ? (split /\s*,\s*/,$_) : ()} $cfg->{Alerts}{to},$tree->{alertee},$alert->{to}){
