Zabbix6.0监控Freeswitch状态

一、前提环境说明

1、最终实现Freeswitch监控指标信息：

在这里插入图片描述

2、环境需求：

（1）需要使用Zabbix6.0及以上
（2）需要使用zabbix_agent2

二、实现步骤

1、zabbix_agent2添加监控键值

cat /etc/zabbix/conf.d/freeswitch.conf
UserParameter=fs.version,/etc/zabbix/shell/freeswitch.sh version
UserParameter=fs.calls,/etc/zabbix/shell/freeswitch.sh calls 
UserParameter=fs.regs,/etc/zabbix/shell/freeswitch.sh regs
UserParameter=fs.thread,/etc/zabbix/shell/freeswitch.sh thread
UserParameter=fs.cpu.usage,/etc/zabbix/shell/freeswitch.sh cpu
UserParameter=fs.memory.usage,/etc/zabbix/shell/freeswitch.sh memory
UserParameter=fs.uptime,/etc/zabbix/shell/freeswitch.sh uptime

2、添加脚本(键值都是通过脚本获取到的值)

cat /etc/zabbix/shell/freeswitch.sh
#!/bin/bash
fsPath="/usr/local/freeswitch/bin/fs_cli -x"
fsPid=$(ps -ef |grep -w ./freeswitch |grep -v grep|awk NR==1|awk '{print $2}')

# 当前注册分级数量
RegistrationNum(){
${fsPath} "sofia status profile internal reg"|grep -w "Total items returned:"|awk '{print $NF}'
}

# 当前通话数量
CallsNum(){
${fsPath} "show calls"|grep -w total.|awk '{print $1}' 
}

# FreeSwitch版本
FreeSwitchVersion(){
${fsPath} "version"|awk NR==1
}

# 线程数量
ThreadNum(){
ps -T -p ${fsPid}|wc -l
}

# FS进程内存使用率
MemoryUsage(){
ps -aux |grep -w ${fsPid}|grep -v grep|awk '{print $4}'
}

# FS进程CPU使用率
CpuUsage(){
ps -aux |grep -w ${fsPid}|grep -v grep|awk '{print $3}'
}

# FS运行时间
UpTime(){
ps -eo pid,comm,etime | grep -w ${fsPid}|awk '{print $NF}'
}

case $1 in 
        "uptime")
        UpTime
        ;;
        "regs")
        RegistrationNum
        ;;
        "calls")
        CallsNum
        ;;
        "version")
        FreeSwitchVersion
        ;;
        "thread")
        ThreadNum
        ;;
        "cpu")
        CpuUsage
        ;;
        "memory")
        MemoryUsage
        ;;
esac

3、重启zabbix_agent2

systemctl restart zabbix-agent2

4、导入模板，把模板内容保存到一个yaml结尾文件中，然后在zabbix导入中选择此文件

模板内容如下：

zabbix_export:
