zabbix自動化初探

zabbix自動化

基於zabbix2.0.2版本

一、定期報表功能

根據screen名稱將screen所展示的內容發給指定用戶的郵件。

1.1配置文件：config.ini

將screen的名稱以逗號分隔，之後以---與report收件地址分隔。多個地址可以分號分隔

WEB_outlets.idc3(CPU),WEB_outlets.idc3(TCP)[email protected]
WEB_music.idc3(MEM)[email protected];[email protected]

1.2主程序：create_script.sh

默認查看近期一週的數據。

腳本會以（爲分隔符，拿到同一類screen的名稱，裏面可以包含cpu、mem等子分類。

#!/bin/bash
#create report script.
config='config.ini'
dbuser='shanks'
dbpass='shanks123'
dbhost='localhost'
dbport=3306
dbname='zabbix'
for zone in `awk -F\('{print $1}' ${config}`
do
  mail_user=`grep -w "${zone}"${config}|awk -F--- '{print $2}'`
cat << hello-DD >${zone}
#!/bin/bash
now=\`date+"%Y%m%d%H%M%S"\`
now_s=\`date+"%s"\`
day_now=\`date+"%d"\`
week=604800
day=\${week}
width=500
url='http://zabbix.shanks.com/chart2.php?'
/usr/sbin/sendmail [email protected] -t << EOF
To:${mail_user}
Subject:ZABBIX-REPORT-${zone}
Content-type:text/html;charset=UTF-8
hello-DD
  for screen in `grep -w "${zone}"${config} |awk -F--- '{print $1}'|sed 's/,/ /g'`
  do
    echo"<p><center><h1><fontcolor=\"#FF0000\"<h1>${screen}</h1></font></h1></center></p>">> ${zone}
    echo "<tablewidth=\"1025\" border=\"1\">" >> ${zone}
    #global set is over,now set the graph.
    #get all of this screen's graphid.
    graphids=`mysql -u${dbuser} -p${dbpass}-h${dbhost} -P${dbport} ${dbname} -e "select resourceid from screens_itemswhere screenid=(select screenid from screens wherename=\"${screen}\")"`
    jishu=1
    num_graphids=`echo${graphids##*resourceid}|awk '{print NR}'`
    echo ${num_graphids}
    for graphid in `echo${graphids##*resourceid}`
    do
      module=$((${jishu}%2))
      if [ ${module} == 1 ]
      then
        if [ ${jishu} ==${num_graphids} ]
        then
          echo"<tr><td><imgsrc=\"\${url}graphid=${graphid}&width=\${width}&period=\${day}&stime=\${now}\"></td></tr>">> ${zone}
        else
          echo"<tr><td><imgsrc=\"\${url}graphid=${graphid}&width=\${width}&period=\${day}&stime=\${now}\"></td>">> ${zone}
        fi 
      elif [ ${module} == 0 ]
      then
        echo "<tr><td><imgsrc=\"\${url}graphid=${graphid}&width=\${width}&period=\${day}&stime=\${now}\"></td></tr>">> ${zone}
      fi
      jishu=$((jishu+1))
    done
    echo "</table>">> ${zone}
  done
  echo "EOF" >> ${zone}
done

1.3生成文件：WEB_music.idc3 WEB_outlets.idc3

之後將WEB_music.idc3 WEB_outlets.idc3賦予可執行權限，並用cron執行即可。

二、批量添加screen

2.1主配置文件：screen.ini

[zabbix]
host=192.168.122.100
db=zabbix
dbuser=shanks
dbpasswd=shanks123
api=http://192.168.122.101/api_jsonrpc.php
zbuser=admin
zbpasswd=shanks

2.2 監控項對應關係：item.ini

顯示名：graph名稱

{
"CPU":"CPU",
"MEM":"mem_free",
"DISK":"DISK",
"TRAFFIC":"traffic",
"TCP":"fluxconns",
"SWAP":"swap_free"
}

2.3 主機、screen對應關係文件：host.ini

Screen的名稱以【】括起，其對應的主機以host=定義，多臺以逗號分隔。

[WEB_shanks.com]
host=web-192.168.122.99-IDC2,web-192.168.122.100-IDC2
[WEB_pp711.com]
host=web-192.168.122.101-IDC2,web-192.168.122.102-IDC2

2.4主程序：screen.py

  screenitem='{"screenid":"'+str(screenid)+'","resourcetype":0,"resourceid": "'+str(resourceid)+'","rowspan":0,"colspan": 0,"width":500,"height":100,"x":'+str(x)+',"y": '+str(y)+'}'
  return screenitem

2.6執行

sh addscreen.sh
