本文介绍如何安装Tsar监控工具及其开发环境，并通过示例演示如何使用Tsar的模块开发工具tsardevel来创建一个针对Nginx的状态监控模块。

摘要生成于 C知道，由 DeepSeek-R1 满血版支持，前往体验 >

1. 安装tsar

# cd /usr/local/src/

wget -O tsar.zip https://github.com/alibaba/tsar/archive/master.zip --no-check-certificate

unzip tsar.zip

该版本解压后的文件夹名称为：tsar-master

cd tsar-master/

make

make install

安装 tsardevel 

make tsardevel 

 
至此，已安装好，可以使用命令
# tsar -l
查看是否成功。

# tsardevel
Usage:
tsardevel modname

表示tsardevel安装成功

2. 配置文件

文件路径为：/etc/tsar/tsar.conf

modules路径为：/usr/local/tsar/modules

3. 使用tsar的模块开发工具tsardevel生成一个模块模板

cd /usr/local/tsar/

tsardevel mod_ngx

cd /usr/local/src/tsar-master/modules/

mv ./mod_nginx.c /usr/local/tsar/mod_ngx/

cd ./mod_ngx/

mv ./mod_nginx.c ./mod_mod_ngx.c

vi mod_mod_ngx.c

unned long long naccept;     /* accepted connections */
unsigned long long nhandled;    /* handled connections */
unsigned long long nrequest;    /* handled requests */
unsigned long long nactive;     /* number of all open connections including connections to backends */
unsigned long long nreading;    /* nginx reads request header */
unsigned long long nwriting;    /* nginx reads request body, processes request, or writes response to a client */
unsigned long long nwaiting;    /* keep-alive connections, actually it is active - (reading + writing) */
unsigned long long nrstime;     /* reponse time of handled requests */

修改 nginx 相关的一些配置
p->host = getenv("NGX_TSAR_HOST");
p->host = p->host ? p->host : "127.0.0.1";

port = getenv("NGX_TSAR_PORT");
p->port = port ? atoi(port) : 80;

p->uri = getenv("NGX_TSAR_URI");
p->uri = p->uri ? p->uri : "/nginx_status";

p->server_name = getenv("NGX_TSAR_SERVER_NAME");
p->server_name = p->server_name ? p->server_name : "status.taobao.com";

 sprintf(request,
            "GET %s HTTP/1.0\r\n"
            "User-Agent: tsar\r\n"
            "Host: %s\r\n"
            "Accept:*/*\r\n"
            "Connection: Close\r\n\r\n",
            hinfo.uri, hinfo.server_name);

tsar --ngx -l

剩下的有时间再做
