十一、 企业微信告警
配置警报媒介类型
1、管理–>警报媒介类型–>新建wx_webhook
(脚本的三个参数都是zabbix内置变量，分别为：报警收件人：{ALERT.SENDTO}、报警标题：{ALERT.SUBJECT}、报警内容：{ALERT.MESSAGE})
名称： qiwei_robot
类型：脚本
脚本名称：wx_webhook.py
脚本参数
参数 :
名称 值
Message {ALERT.MESSAGE}
Subject {ALERT.SUBJECT}
To {ALERT.SENDTO}
Token 2fe963bf-7a37-4ab4-90d1-55569ff533e3 # 群聊机器人webhook地址的key
脚本：
```python
var Wechat = {
token: null,
to: null,
message: null,
parse_mode: null,
sendMessage: function() {
var params = {
msgtype: "markdown",
chat_id: Wechat.to,
markdown: {
content:Wechat.message
},
disable_web_page_preview: true,
disable_notification: false
},
data,
response,
request = new CurlHttpRequest(),
url = 'https://qyapi.weixin.qq.com/cgi-bin/webhook/send?key=' + Wechat.token;
if (Wechat.parse_mode !== null) {
params['parse_mode'] = Wechat.parse_mode;
}
request.AddHeader('Content-Type: application/json');
data = JSON.stringify(params);
// Remove replace() function if you want to see the exposed token in the log file.
Zabbix.Log(4, '[Wechat Webhook] URL: ' + url.replace(Wechat.token, '<TOKEN>'));
Zabbix.Log(4, '[Wechat Webhook] params: ' + data);
response = request.Post(url, data);
Zabbix.Log(4, '[Wechat Webhook] HTTP code: ' + request.Status());
Zabbix.Log(4, '[Wechat Webhook] response: ' + response);
try {
response = JSON.parse(response);
}
catch (error) {
response = null;
Zabbix.Log(4, '[Wechat Webhook] response parse error');
}
if (request.Status() !== 200 || response.errcode !== 0 || response.errmsg !== 'ok') {
if (typeof response.errmsg === 'string') {
throw response.errmsg;
}
else {
throw 'Unknown error. Check debug log for more information.'
}
}
}
}
try {
var params = JSON.parse(value);
if (typeof params.Token === 'undefined') {
throw 'Incorrect value is given for parameter "Token": parameter is missing';
}
Wechat.token = params.Token;
if (['Markdown', 'HTML', 'MarkdownV2'].indexOf(params.ParseMode) !== -1) {
Wechat.parse_mode = params.ParseMode;
}
Wechat.to = params.To;
Wechat.message = params.Subject + '\n' + params.Message;
Wechat.sendMessage();
return 'OK';
}
catch (error) {
Zabbix.Log(4, '[Wechat Webhook] notification failed: ' + error);
throw 'Sending failed: ' + error + '.';
}
2、配置Message templates
报警媒介类型–>Message type
问题模板
message type: 问题
主题：告警通知
消息:
当前状态:<font color="warning">{
TRIGGER.STATUS}</font>
告警IP:{
HOST.IP}
所属群组:{
TRIGGER.HOSTGROUP.NAME}
告警等级:<font color="warning">{
TRIGGER.SEVERITY}</font>
告警信息:{
TRIGGER.NAME}
当前详情:{
ITEM.NAME} <font color="warning">{
ITEM.VALUE}</font>
告警时间:{
EVENT.DATE} {
EVENT.TIME}
问题恢复模板
message type: promeble recovery
主题：恢复通知
消息:
当前状态:<font color="info">{
TRIGGER.STATUS}</font>
告警IP:{
HOST.IP}
所属群组:{
TRIGGER.HOSTGROUP.NAME}
告警信息:{
TRIGGER.NAME}
当前详情:{
ITEM.NAME} <font color="info">{
ITEM.VALUE}</font>
恢复时间:{
EVENT.RECOVERY.DATE} {
EVENT.RECOVERY.TIME}
持续时间:{
EVENT.AGE}
二、设置action，使警报生效
配置–>动作–>trigger actions–>创建动作
1、动作–>名称：wx_webhook
条件：触发器示警度 大于等于 警告
2、操作–>
默认操作步骤持续时间: 1h
操作
步骤： 1 - 3 #以持续时间为间隔发送3次，条件为没有确认
步骤持续时间： 60s #60秒内不重复发送告警
发送消息给用户: Admin
发送消息给用户群组: Zabbix administrators
仅送到：wx_webhook
条件： Event is not acknowledged
三、对用户配置告警策略
管理–>用户–>Admin(选择用户)–>报警媒介–>添加
类型：wx_webhook (自定义名称)
收件人： 通信员 （随便）
当启用时： 1-7,00:00-24:00 （默认就好）
4、验证
十二、使用elasticsearch存放历史数据
https://blog.csdn.net/peyte1/article/details/84941560
十三、zabbix监控tcp scoket 状态
tcp_status脚本
cat > /etc/zabbix/zabbix_agent2.d/tcp_status.sh << 'EOF' #!/bin/bash #用ss生成scoket的状态文件, tcp_check_interval(){ INTERVAL_TIME=$1 timestamp=`date +%s` filepath=/dev/shm/tcp_conn.txt if [ ! -f $filepath ];then touch $filepath fi if [ -f $filepath ];then filetimestamp=`stat -c %Y $filepath` timecha=$[$timestamp - $filetimestamp] if [ $timecha -gt $INTERVAL_TIME ];then ss -ant| awk 'NR>1 {++s[$1]} END {for(k in s) print k,s[k]}' > /dev/shm/tcp_conn.txt fi fi echo $INTERVAL_TIME } #读取scoket的状态文件 tcp_conn_status(){ TCP_STAT=$1 TCP_NUM=$(grep "$TCP_STAT" /dev/shm/tcp_conn.txt|cut -d ' ' -f2) if [ -z $TCP_NUM ];then TCP_NUM=0 fi echo $TCP_NUM } main(){ case $1 in tcp_check_interval) tcp_check_interval $2; ;; tcp_status) tcp_conn_status $2; ;; esac } main $1 $2 EOF
cat > /etc/zabbix/zabbix_agent2.d/tcp_status.conf << 'EOF' UserParameter=tcp_status[*],/bin/bash /etc/zabbix/zabbix_agent2.d/tcp_status.sh $1 $2 EOF
配置模板
触发器
名称： ESTAB连接数超过告警值4w
严重性： 严重
问题表现形式： last(/gw_pro_tcp_status_jiankong/tcp_status[“tcp_status”,“ESTAB”])>40000
恢复表达式： last(/gw_pro_tcp_status_jiankong/tcp_status[“tcp_status”,“ESTAB”])<=40000
十四、web场景监控
1、配置–》》模板–》》创建模板–》》模板
模版名称： gw_healthcheck
可见的名称： 服务自检_healthcheck
群组：Templates
2、配置–》》模板–》》创建模板–》》宏
宏： {$SMARTGATE_PORT}

URL： http://{HOST.CONN}:{$SMARTGATE_PORT}/dail_healthcheck
超时：15s
要求的字串：返回成功
要求的状态码：200
触发器
表达式：count(/gw_healthcheck/web.test.rspcode[gw_self_healthcheck,gw_self_healthcheck],2m,“200”)<2 and last(/gw_healthcheck/web.test.rspcode[gw_self_healthcheck,gw_self_healthcheck])<>200
十五、zabbix LLD
参考：https://www.cnblogs.com/smail-bao/p/6043726.html --初级
https://blog.csdn.net/u013272009/article/details/90486079–高级
十六、zabbix基于ansible的自动化集成
https://github.com/smejdil/import-default-zabbix-templates --自动加载模板 （支持xml和json格式）
注意：ansible 使用python3版本
#安装依赖
yum install python3-pip git lrzsz -y
pip3 install zabbix-api
cd /tmp/
git clone https://github.com/smejdil/import-default-zabbix-templates
cd import-default-zabbix-templates
#ansbile-galaxy只支持ansible 2.9以上版本
#ansible-galaxy collection install -r requirements.yml
#下载ansible-galaxy模块：https://galaxy.ansible.com/community/zabbix
#本地文件安装
#wget https://galaxy.ansible.com/download/community-zabbix-1.5.1.tar.gz
#ansible-galaxy collection install ./community-zabbix-1.5.1.tar.gz
ansible-galaxy collection install community.zabbix:1.5.1
export ZABBIX_USER=Admin
export ZABBIX_PASSWORD=zabbix
export ZABBIX_VERISON="6.0.5"
mkdir /tmp/zabbix/templates/app/gateway -p #把模板放到目录下,支持xml和json格式的模板
cd /tmp/
tar cvzf zabbix-templates-${ZABBIX_VERISON}.tar.gz zabbix/templates/
cd /tmp/import-default-zabbix-templates
vi /tmp/import-default-zabbix-templates/vars/vars.yml
#修改vars/vars.yml下的变量
server_url: http://192.168.11.101:8080 #修改此值为zabbix的真实IP
validate_certs: no
cd /tmp/import-default-zabbix-templates
bash -x import-zabbix-templates.sh
十七、zabbix_proxy
#zabbix_porxy与zabbix部署在不同的服务器上
mkdir /data/zabbix/zabbix_proxy -p && cd /data/zabbix/zabbix_proxy
cat > start.sh << 'EOF' #!/bin/bash docker rm -f zabbix_proxy cd `dirname $0` docker run -d \ --name zabbix_proxy \ --restart always \ -p 10061:10051 \ --add-host=zabbix-server:192.168.11.101 \ -v /etc/localtime:/etc/localtime:ro \ -v `pwd`/data/externalscripts:/usr/lib/zabbix/externalscripts:ro \ -v `pwd`/data/modules:/var/lib/zabbix/modules:ro \ -v `pwd`/data/enc:/var/lib/zabbix/enc:ro \ -v `pwd`/data/ssh_keys:/var/lib/zabbix/ssh_keys:ro \ -v `pwd`/data/mibs:/var/lib/zabbix/mibs:ro \ -v `pwd`/data/snmptraps:/var/lib/zabbix/snmptraps:rw \ -e ZBX_HOSTNAME=zabbix-proxy-sqlite3 \ -e ZBX_PROXYMODE=0 \ -e ZBX_SERVER_HOST=zabbix-server \ -e ZBX_SERVER_PORT=10051 \ -e ZBX_TIMEOUT=30 \ zabbix/zabbix-proxy-sqlite3:alpine-6.0-latest EOF
bash start.sh
配置代理：
管理–》》agent代理程序–》》创建代理
agent代理程序名称：zabbix-proxy-sqlite3 #与zabbix_proxy的配置ZBX_HOSTNAME对应一致
十八、psk加密
#生成psk密码
openssl rand -hex 32 > /etc/zabbix/zabbix_agent2.d/zabbix.psk
#配置zabbix-agent2
vi /etc/zabbix/zabbix-agent2.conf
TLSConnect=psk
TLSAccept=psk
TLSPSKIdentity=PSK 001
TLSPSKFile=/etc/zabbix/zabbix_agent2.d/zabbix.psk
#配置服务器上的”主机加密项“
配置成功后会出现以下提示
