最近写了一个检测网站是否能正常登陆的php脚本，并可以作为Nagios插件使用
Nagios插件是Nagios提供的一种可通过扩展方式部署的组件，该插件支持Java、CC 、php等多种语言开发，操作员通过修改配置文件和相应参数，就能很方便地将该插件集成到Nagios中，实现对目标系统的监控。
Nagios插件程序可以提供两个返回值，一个是插件的退出状态码，一个是插件在控制台打印的第一行数据。退出状态码可以被Nagios主程序作为判断被监控系统服务状态的依据，控制台打印的第一行数据可以被Nagios主程序作为被监控系统服务状态的补充说明。
Nagios主程序可识别的状态码和说明如下：
状态码 说明 0 OK 1 WARNING 2 CRITICAL 3 UNKOWN ********下面是php脚本的内容*********** #!/usr/bin/php if($argc < 3){ echo 'php '.$argv[0].' ‘.PHP_EOL; exit(1); } class http{ private $_curl; private $_user_agent; private $_cookie; private $_getopt = array(); private $_postopt = array(); function __construct(){ $this->_user_agent = ‘Mozilla/5.0 (Windows NT 6.1; rv:15.0) Gecko/20100101 Firefox/15.0.1′; $this->_cookie = ‘/tmp/cookie.txt’; } public function get($url){ $this->_getopt = array(CURLOPT_CONNECTTIMEOUT => 20, CURLOPT_URL => $url, CURLOPT_HEADER => 0, CURLOPT_NOBODY => 1, //CURLOPT_COOKIEJAR => $this->_cookie, //CURLOPT_COOKIEFILE => $this->_cookie, CURLOPT_USERAGENT => $this->_user_agent, CURLOPT_RETURNTRANSFER => 1); $this->_curl = curl_init(); curl_setopt_array($this->_curl, $this->_getopt); $data = curl_exec($this->_curl); $http_code = curl_getinfo($this->_curl, CURLINFO_HTTP_CODE); $time_total = curl_getinfo($this->_curl, CURLINFO_TOTAL_TIME); $retval = $http_code.’,’.$time_total; curl_close($this->_curl); return $retval; } public function post($url,Array $post){ $this->_postopt = array(CURLOPT_CONNECTTIMEOUT => 20, CURLOPT_URL => $url, CURLOPT_HEADER => 0, CURLOPT_COOKIEJAR => $this->_cookie, CURLOPT_POST => 1, CURLOPT_POSTFIELDS => http_build_query($post), CURLOPT_USERAGENT => $this->_user_agent, CURLOPT_RETURNTRANSFER => 1); $this->_curl = curl_init(); curl_setopt_array($this->_curl, $this->_postopt); $data = curl_exec($this->_curl); curl_close($this->_curl); return $data; } public function rpost($url){ $this->_postopt = array(CURLOPT_CONNECTTIMEOUT => 20, CURLOPT_URL => $url, CURLOPT_HEADER => 1, CURLOPT_NOBODY => 1, CURLOPT_COOKIEFILE => $this->_cookie, CURLOPT_USERAGENT => $this->_user_agent, CURLOPT_RETURNTRANSFER => 1); $this->_curl = curl_init(); curl_setopt_array($this->_curl, $this->_postopt); $data = curl_exec($this->_curl); $http_code = curl_getinfo($this->_curl, CURLINFO_HTTP_CODE); $time_namelookup = curl_getinfo($this->_curl, CURLINFO_NAMELOOKUP_TIME); $time_connect = curl_getinfo($this->_curl, CURLINFO_CONNECT_TIME); $time_starttransfer = curl_getinfo($this->_curl, CURLINFO_STARTTRANSFER_TIME); $time_total = curl_getinfo($this->_curl, CURLINFO_TOTAL_TIME); $size_download = curl_getinfo($this->_curl, CURLINFO_SIZE_DOWNLOAD); $speed_download = curl_getinfo($this->_curl, CURLINFO_SPEED_DOWNLOAD); curl_close($this->_curl); //$retval = date(‘Y-m-d_H:i:s’).’,’.$http_code.’,’.$time_namelookup.’,’.$time_connect.’,’.$time_starttransfer.’,’.$time_total.’,’.$size_download.’,’.$speed_download.’,’.$url; $retval = $http_code.’,’.$time_total; return $retval; } } class ciwong{ private $_username; private $_passwd; private $_http; private $_sid; function __construct($username = ’3sdf’, $passwd = ‘dfser’){ $this->_username = $username; $this->_passwd = $passwd; $this->_http = new http(); } public function postLogin($url){ $post_url = ‘http://passport.ciwong.com/signin’; $post['username'] = $this->_username; $post['password'] = $this->_passwd; $post['returnUrl'] = $url; $data = $this->_http->post($post_url, $post); $data = $this->_http->rpost($url); return $data; } public function getUrl($url){ $data = $this->_http->get($url); return $data; } } $type = $argv[1]; $url = $argv[2]; $username = ’3244′; $passwd = ’3423′; $status_ok = 0; $status_warning = 1; $cw = new ciwong($username, $passwd); switch($type){ case ‘get’: $retval = $cw->getUrl($url); list($http_status, $time_total) = explode(‘,’, $retval); if ($http_status==200 || $http_status==301 || $http_status==302){ echo “HTTP OK: Status line output is ”$http_status” – $time_total second response timen”; exit($status_ok); }else{ echo “HTTP WARNING: Status line output is ”$http_status” – $time_total second response timen”; exit($status_warning); } break; case ‘post’: $retval = $cw->postLogin($url); list($http_status, $time_total) = explode(‘,’, $retval); if($http_status==200 || $retval==301 || $retval==302){ echo “HTTP OK: Status line output is ”$http_status” – $time_total second response timen”; exit($status_ok); }else{ echo “HTTP WARNING: Status line output is ”$http_status” – $time_total second response timen”; exit($status_warning); } break; default: echo ‘php ‘.$argv[0].’ ‘.PHP_EOL; exit(1); } ***********************over*******************************
