8月3日,我写了“Linux服务器监控系统 ServMon V1.0”,今天,ServMon V1.1 版本亮相。
ServMon的原理是用shell脚本定时抓取被监控Linux服务器上的信息,再用curl POST到监控机的PHP接口程序上,由PHP接口程序对信息进行分析,如果存在异常,则发送报警邮件给管理员。报警邮件演示页面请见:http://blog.zyan.cc/read.php/276.htm
ServMon V1.1 在 1.0 的基础上,增加了对Linux系统负载的监控,并编写了客户端自动安装包:
1、被监控端服务器(Linux)
(1)、下载并安装ServMon Client
注:此处的password为interface.php程序中设置的数据传输验证密码。
客户端安装包源码:
│
├─install
├─[src]
│ ├─[bin]
│ │ ├─diskstat_send
│ │ ├─loadstat_send
│ │ └─swapstat_send
│ ├─[cron]
│ │ └─servmon
│ └─[data]
屏幕演示:
2、监控端服务器配置(Linux)
(1)、启动sendmail
/usr/sbin/sendmail -bd -q30m
-b:指定Sendmail在后台运行,并且监听端口25的请求。
-d:指定Sendmail以Daemon方式运行(守护进程)。
-q:当Sendmail无法将邮件成功地发送到目的地时,它会将邮件保存在队列里。该参数指定邮件在队列里保存的时间。其中的30m表示保留30分钟。
(2)、修改php.ini的[mail function]部分为以下内容,然后重启Apache,使PHP能够使用mail()函数发送电子邮件
(4)、在MySQL上创建一个数据库servmon,然后在该数据库中执行以下SQL语句创建表:
备注:这张表是PHP接口程序用来记录发送磁盘分区报警邮件的时间,避免在一段时间内重复发送大量报警邮件的。
(3)、PHP接口程序

Regardless, nothing is said about escorts for those who sign up to one of the prominent female escorts. You don't have to load too much on the calculation that these things depend on appealing to you as an escort and basically offering pleasure. They're going to be open skirts for this kind of inclination, and with little respect for the possibility that they've encountered anything with Escort in one of their former clients, they Will not show that Escort in with you.
