天兔3.8主机监控中添加内存统计图

前提：已经安装天兔3.8成功

添加内存统计步骤：

一.在/opt/lampp/htdocs/lepus/application/controllers/lp_os.php 文件中添加，目的是让chart_reslut中有内存数据mem_total、mem_avail、mem_cached (名字对应数据库中 os_status_history表中 相应的字段名)：

在181行后处插入如下代码

                $chart_reslut[$i]['mem_total'] = $dbdata['mem_total'];
                $chart_reslut[$i]['mem_avail'] = $dbdata['mem_avail'];
                $chart_reslut[$i]['mem_cached'] = $dbdata['mem_cached'];

未插入前代码

   public function chart(){
        
        parent::check_privilege();
        $host = $this->uri->segment(3);
        $host=!empty($host) ? $host : "";
        $begin_time = $this->uri->segment(4);
        $begin_time=!empty($begin_time) ? $begin_time : "30";
        $time_span = $this->uri->segment(5);
        $time_span=!empty($time_span) ? $time_span : "min";
        
        //连接数图表
        $chart_reslut=array();              
        for($i=$begin_time;$i>=0;$i--){
            $timestamp=time()-60*$i;
            $time= date('YmdHi',$timestamp);
            $has_record = $this->os->check_has_record($host,$time);
            if($has_record){
                $chart_reslut[$i]['time']=date('Y-m-d H:i',$timestamp);
                $dbdata=$this->os->get_os_chart_record($host,$time);
                $chart_reslut[$i]['process'] = $dbdata['process'];
                $chart_reslut[$i]['load_1'] = $dbdata['load_1'];
                $chart_reslut[$i]['load_5'] = $dbdata['load_5'];
                $chart_reslut[$i]['load_15'] = $dbdata['load_15'];
                $chart_reslut[$i]['cpu_user_time'] = $dbdata['cpu_user_time'];
                $chart_reslut[$i]['cpu_system_time'] = $dbdata['cpu_system_time'];
                $chart_reslut[$i]['cpu_idle_time'] = $dbdata['cpu_idle_time'];
                $chart_reslut[$i]['mem_usage_rate'] = $dbdata['mem_usage_rate'];
                $chart_reslut[$i]['disk_io_reads_total'] = $dbdata['disk_io_reads_total'];
                $chart_reslut[$i]['disk_io_writes_total'] = $dbdata['disk_io_writes_total'];
                $chart_reslut[$i]['net_in_bytes_total'] = $dbdata['net_in_bytes_total'];
                $chart_reslut[$i]['net_out_bytes_total'] = $dbdata['net_out_bytes_total'];
            }
 
        }
        $data['chart_reslut']=$chart_reslut;
    
        $chart_option=array();
        if($time_span=='min'){
            $chart_option['formatString']='%H:%M';
        }
        else if($time_span=='hour'){
            $chart_option['formatString']='%H:%M';
        }
        else if($time_span=='day'){
            $chart_option['formatString']='%m/%d %H:%M';
        }
        
        $data['chart_option']=$chart_option;
      
        $data['begin_time']=$begin_time;
        $data['cur_host']=$host;
        $data['last_record'] = $this->os->get_last_record($host);
        $data['diskinfo'] = $this->os->get_disk_record($host);
        $this->layout->view('os/chart',$data);
    }

插入后：

   public function chart(){
        
        parent::check_privilege();
        $host = $this->uri->segment(3);
        $host=!empty($host) ? $host : "";
        $begin_time = $this->uri->segment(4);
        $begin_time=!empty($begin_time) ? $begin_time : "30";
        $time_span = $this->uri->segment(5);
        $time_span=!empty($time_span) ? $time_span : "min";
        
        //连接数图表
        $chart_reslut=array();              
        for($i=$begin_time;$i>=0;$i--){
            $timestamp=time()-60*$i;
            $time= date('YmdHi',$timestamp);
            $has_record = $this->os->check_has_record($host,$time);
            if($has_record){
                $chart_reslut[$i]['time']=date('Y-m-d H:i',$timestamp);
                $dbdata=$this->os->get_os_chart_record($host,$time);
                $chart_reslut[$i]['process'] = $dbdata['process'];
                $chart_reslut[$i]['load_1'] = $dbdata['load_1'];
                $chart_reslut[$i]['load_5'] = $dbdata['load_5'];
                $chart_reslut[$i]['load_15'] = $dbdata['load_15'];
                $chart_reslut[$i]['cpu_user_time'] = $dbdata['cpu_user_time'];
                $chart_reslut[$i]['cpu_system_time'] = $dbdata['cpu_system_time'];
                $chart_reslut[$i]['cpu_idle_time'] = $dbdata['cpu_idle_time'];
                $chart_reslut[$i]['mem_usage_rate'] = $dbdata['mem_usage_rate'];
                $chart_reslut[$i]['disk_io_reads_total'] = $dbdata['disk_io_reads_total'];
                $chart_reslut[$i]['disk_io_writes_total'] = $dbdata['disk_io_writes_total'];
                $chart_reslut[$i]['net_in_bytes_total'] = $dbdata['net_in_bytes_total'];
                $chart_reslut[$i]['net_out_bytes_total'] = $dbdata['net_out_bytes_total'];
                $chart_reslut[$i]['mem_total'] = $dbdata['mem_total'];   #插入的代码
                $chart_reslut[$i]['mem_avail'] = $dbdata['mem_avail'];   #插入的代码
                $chart_reslut[$i]['mem_cached'] = $dbdata['mem_cached']; #插入的代码

            }
 
        }
        $data['chart_reslut']=$chart_reslut;
    
        $chart_option=array();
        if($time_span=='min'){
            $chart_option['formatString']='%H:%M';
        }
        else if($time_span=='hour'){
            $chart_option['formatString']='%H:%M';
        }
        else if($time_span=='day'){
            $chart_option['formatString']='%m/%d %H:%M';
        }
        
        $data['chart_option']=$chart_option;
      
        $data['begin_time']=$begin_time;
        $data['cur_host']=$host;
        $data['last_record'] = $this->os->get_last_record($host);
        $data['diskinfo'] = $this->os->get_disk_record($host);
        $this->layout->view('os/chart',$data);
    }

二、在/opt/lampp/htdocs/lepus/application/views/os/chart.php中插入代码

插入代码1：在43行插入如下代码，目的是在详情页中插入一个层，用来存放统计内存图表：

<div id="memory" style="margin-top:5px; margin-left:10px; 96%; height:300px; "></div>

插入代码前：

<div id="cpu_load" style="margin-top:5px; margin-left:10px; 96%; height:300px;"></div>
<div id="cpu_utilization" style="margin-top:5px; margin-left:10px; 96%; height:300px;"></div>
<div id="process" style="margin-top:5px; margin-left:10px; 96%; height:300px; "></div>
<div id="network" style="margin-top:5px; margin-left:10px; 96%; height:300px; "></div>
<div id="diskio" style="margin-top:5px; margin-left:10px; 96%; height:300px; "></div>

插入代码后：

<div id="cpu_load" style="margin-top:5px; margin-left:10px; 96%; height:300px;"></div>
<div id="cpu_utilization" style="margin-top:5px; margin-left:10px; 96%; height:300px;"></div>
<div id="process" style="margin-top:5px; margin-left:10px; 96%; height:300px; "></div>
<div id="network" style="margin-top:5px; margin-left:10px; 96%; height:300px; "></div>
<div id="diskio" style="margin-top:5px; margin-left:10px; 96%; height:300px; "></div>
<div id="memory" style="margin-top:5px; margin-left:10px; 96%; height:300px; "></div>   #插入的代码

插入代码2：在148行后插入如下代码，目的是在上面的层上画内存统计图（单位是KB）：
