Jitsi Meetの会議開催状況をログ・ファイルから取得する

 前回及び前々回は閉域網にJitsi Meetの構築を紹介しました。COVID-19感染拡大の影響で院内のビデオ会議によるカンファレンス等のニーズが増えてきました。電子カルテのネットワークに影響を避けるため、Jitsi Meetの利用状況をログファイルから取得するようにしました。

ログファイルのサンプル：

Jicofo 2021-09-18 07:52:01.657 情報: [88] org.jitsi.jicofo.xmpp.FocusComponent.log() Focus request for room: test@conference.10.120.8.204

そして、下記のようなテーブルにしてみました。

2021-09-18
会議名-開催回開始時刻終了時刻延べ参加者数現在参加者数
kannfarennsu -107:29:02.33507:29:18.30710

test -107:52:01.65807:55:07.07110



phpをJitsi Meetと同じサーバに実装する場合、必要ないのですが、こちらのサンプルは、BitnamiのRedmineで使うApache2に実装したため、Windows版のsshfsを使ってWindows 2019サーバにマウントして取得しています。

以下はPHP

<html>
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width">
    <meta http-equiv="refresh" content="300";>
    <title>Document</title>
</head>
<body>
<?php
date_default_timezone_set('Asia/Tokyo');
$date = new DateTime();
print "<hr>Jitsiビデオ会議サーバ２０４利用状況　　　更新日時：".$date->format('Y-m-d H:i:s')."<hr>";

function log2table($logfile) {
$filter=['Created','Member','Disposed'];
$room_used=[];
$start_time=[];
$total_member=[];
$current_member=[];
$end_time=[];

$fp=fopen($logfile,'r');
while (!feof($fp)) {
$line=fgets($fp);
$fields=explode(" ",$line);
if (in_array($fields[6],$filter)){
$room = preg_replace('/.* ([^ ]*)@conference(.*)/i','$1',$line);
if (!array_key_exists($room,$room_used)) {
$room_used[$room]=0;
$today=$fields[1];
}
if ($fields[6]=='Created'){
$room_used[$room]=$room_used[$room]+1;
//$start_time[$room."-".$room_used[$room]]=$fields[1]." ".$fields[2];
$start_time[$room."-".$room_used[$room]]=$fields[2];
$total_member[$room."-".$room_used[$room]]=0;
$current_member[]=0;
}
if ($fields[6]=='Member'){
if (substr($fields[8],0,6)=='joined'){
$total_member[$room."-".$room_used[$room]]=$total_member[$room."-".$room_used[$room]]+1;
$current_member[$room."-".$room_used[$room]]=$current_member[$room."-".$room_used[$room]]+1;
}
if (substr($fields[9],0,7)=='leaving'){
$current_member[$room."-".$room_used[$room]]=$current_member[$room."-".$room_used[$room]]-1;
}
}

if ($fields[6]=='Disposed'){
//$end_time[$room."-".$room_used[$room]]=$fields[1]." ".$fields[2];
$end_time[$room."-".$room_used[$room]]=$fields[2];
}
}
}
fclose($fp);

print "<hr>".$today."<hr>";
print '<table border=1><tr><td>会議名-開催回</td><td>開始時刻</td><td>終了時刻</td><td>延べ参加者数</td><td>現在参加者数</td></tr>';
foreach ($start_time as $key => $value){
print '<tr><td>'.$key."</td><td>".$value."</td><td>".$end_time[$key]."</td><td>".$total_member[$key]."</td><td>".$current_member[$key]."</td></tr>";
}
print '</table>';
}

log2table("C:/Bitnami/redmine-4.1.1-5/apache2/htdocs/tools/jicofo.log");
