zabbix 自动发现端口服务监控教程

前言:

1、线上业务使用了几十上百台haproxy服务,需要针对这些服务做监控(包含haproxy端口对应的TCP连接数监控,haproxy服务监控等)。

2、普通的在zabbix_agentd.conf里面配置"UserParameter"的方式太繁琐,这里使用建表(收集数据,汇总数据)的方式。

3、将数据汇总到表里面,通过第三方脚本对数据做一个处理,拿到处理结果并监控。

创建数据表(收集haproxy服务的信息)

  1. 在zabbix_DB上创建表:t_3party_server

create table t_3party_server(
app varchar(64) NOT NULL,
server varchar(64) NOT NULL,
division varchar(64) NOT NULL,
node varchar(64) NOT NULL,
port varchar(64) NOT NULL,
remark int(10) unsigned NOT NULL,
PRIMARY KEY (app,server,division,node,port) 
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

注释:
app          #这里写的是项目名称(MM项目)
server       #服务名称(haproxy服务)
division     #由于起了多个haproxy实例,名称也不一样,所以这里做了区分
node         #haproxy服务IP地址
port         #haproxy服务端口,多个实例端口不同  
remark       #备注作用(由于线上某些haproxy服务安装路径不一致,所以此处用来区分路径,也可以区分其他)
PRIMARY KEY (app,server,division,node,port)  #添加主键
  1. 执行完毕之后查看表结构

  1. 然后往数据表里面插入数据:

    insert into t_3party_server(app,server,division,node,port,remark) values('MM','haproxy','haproxy-login','192.168.32.128','30000','0');
    
  2. 最终表格效果

针对生成的数据表做监控

监控脚本:放在zabbix_server下 "/install_path/zabbix_server/share/zabbix/externalscripts"

<?php
 
if ($_SERVER["argc"] != 2) {
        echo "Usage: " . $_SERVER["argv"][0] . " host\n";
        return;
}
 
$host = $_SERVER["argv"][1];
 
$mysqlconn = new mysqli("localhost", "root", "123", "zabbix", 3306);
if (mysqli_connect_errno()) {
        echo "fail to connect mysql: " . mysqli_connect_error() . "\n";
        return;
}
 
$result = $mysqlconn->query("SELECT * FROM t_3party_server WHERE node=\"" . $mysqlconn->real_escape_string($host) . "\"");
 
$hostvalue = array(
        "data" => array()
);
while ($row = $result->fetch_assoc()) {
        $app = $row["app"];
        $server = $row["server"];
        $division = $row["division"];
        $node = $row["node"];
        $port = $row["port"];
        $remark = $row["remark"];
 
        if ($remark == "/usr/local")
        {
            $hostvalue["data"][] = array(
                "{#APP}" => $app,
                "{#SERVER}" => $server,
                "{#DIVISION}" => $division,
                "{#PORT}" => $port,
                "{#PATH}" => "/usr/local/" . $division . "/sbin",
            );
 
             continue;
        }
 
        $server = substr($server, 0, 15);
 
        $hostvalue["data"][] = array(
                "{#APP}" => $app,
                "{#SERVER}" => $server,
                "{#DIVISION}" => $division,
                "{#PORT}" => $port,
                "{#PATH}" => "/data/app/" . $division . "/sbin",
                #"{#MFW_PATH}" => "/data/app/" . $division . "/" . ($division ? $division . "/" : "") . $server,
        );
}
 
echo json_encode($hostvalue);
echo "\n";

脚本生成的数据:

[root@localhost externalscripts]# ./haproxy_discovery.php 192.168.32.128
{"data":[{"{#APP}":"MM","{#SERVER}":"haproxy","{#DIVISION}":"haproxy-login","{#PORT}":"30000","{#PATH}":"\/data\/app\/haproxy-login\/sbin"}]}

转换的json格式如下:

{
    "data":[
        {
            "{#APP}":"MM",
            "{#SERVER}":"haproxy",
            "{#DIVISION}":"haproxy-login",
            "{#PORT}":"30000",
            "{#PATH}":"/data/app/haproxy-login/sbin"
        }
    ]
}

在haproxy服务机器上配置

1、配置:zabbix_agentd.conf

#用来监控TCP连接数
UserParameter=haproxy.tcp.[*],/usr/sbin/ss -ant sport eq :"$1" | awk 'NR>1{++s[$$1]} END {for(k in s){print k,s[k]}}' |grep -w "ESTAB" |awk '{print $$2}'

配置完成后重启zabbix_agentd

在zabbix上添加监控

创建模板-->自动发现规则

定义宏变量:宏的值为json导出后的值

Item1:检查haproxy进程是否存在
Key:proc.num["{#SERVER}",,,"{#PATH}"]

Trigger1:对应Item1
{customize template:proc.num["{#SERVER}",,,"{#PATH}"].last()}<1

Item2:检查haproxy端口对应的TCP连接数   
Key:haproxy.tcp.[{#PORT}]

Trigger2:对应Item2
{Template moba server:haproxy.tcp.[{#PORT}].last()}>40000

之后新增haproxy服务添加到监控的流程如下

1、在zabbixDB上的t_3party_server表里添加数据:
INSERT INTO `zabbix`.`t_3party_server` (`app`, `server`, `division`, `node`, `port`, `remark`) VALUES ('MM', 'haproxy', 'haproxy', '192.168.32.128', '30000', '0');
  
2、在机器上添加配置参数:
vim /data/app/zabbix_agent/etc/zabbix_agentd.conf
#Haproxy
UserParameter=haproxy.tcp.[*],/usr/sbin/ss -ant sport eq :"$1" | awk 'NR>1{++s[$$1]} END {for(k in s){print k,s[k]}}' |grep -w "ESTAB" |awk '{print $$2}'

3、配置完毕后重启 zabbix_agentd
pkill zabbix_agentd
/data/app/zabbix_agent/sbin/zabbix_agentd
 
4、到zabbix上监控haproxy服务是否被监控
