下载：
# wget http://code.taobao.org/p/tsar/file/1787/tsar-2.1.0.tar.gz
安装：
# tar zxvf tsar-2.1.0.tar.gz
# cd tsar-2.1.0
# ./configure –prefix=/usr/local/tsar (新版本的需要执行这一步，老版本的直接不需要执行此步)
# make && make install
配置文件详解：
1、主配置文件路径：/etc/tsar/tsar.conf
#debug_level(INFO DEBUG WARN ERROR FATAL)
debug_level FATAL ##指定tsar的运行级别，主要用来调试使用
#[module] on/off to enable mod ##开启指定模块
mod_cpu on
mod_mem on
mod_swap on
mod_tcp on
mod_udp on
mod_traffic on
mod_io on
mod_pcsw on
mod_partition on
mod_tcpx on
mod_load on
#output type:file,nagios,db
output_interface file,nagios ##设置输出类型，支持file，nagios，db
#[output_file] original data to store
output_file_path /var/log/tsar.data ##设置文件类型输出的写入文件
#[output_stdio] these mod will be show as using tsar
output_stdio_mod mod_swap,mod_partition,mod_cpu,mod_mem,mod_traffic,mod_load,mod_tcp,mod_udp,mod_tcpx,mod_pcsw,mod_io ##设置用户终端默认显示的模块
#[output_nagios] the alert will be report to nagios server
output_nagios_mod mod_swap,mod_partition,mod_cpu,mod_mem,mod_traffic,mod_load,mod_tcp,mod_udp,mod_tcpx,mod_pcsw,mod_io ##设置哪些模块输出到nagios
#[output_db]
#output_db_mod mod_swap,mod_partition,mod_cpu,mod_mem,mod_traffic,mod_load,mod_tcp,mod_udp,mod_tcpx,mod_pcsw,mod_io ##设置哪些模块输出到数据库
#output_db_addr console2:56677
#support include other mod conf
include /etc/tsar/conf.d/*.conf ##支持include配置，主要用来加载用户的自定义模块
2、nagios配置文件路径：/etc/tsar/nagios.conf
#The IP address of the host running the NSCA daemon
server_addr mmdev4.corp.alimama.com
#The port on which the daemon is running – default is 5667
server_port 8086
#The cycle of send alert to nagios
cycle_time 300 ##指定上报的间隔时间，由于tsar每一分钟采集一次，上报时会判断是否符合时间间隔，如设置300的话，则在0，5等整点分钟会上报nagios
#nsca client program
send_nsca_cmd /usr/bin/send_nsca
send_nsca_conf /home/a/conf/amon/send_nsca.conf
#tsar mod alert config file
#threshold [hostname.]servicename.key;w-min;w-max;c-min;cmax; ##设置某个要报警项的阀值,前面是模块和要监控的具体名称，后面的四个数据代表报警的范围，warn和critical的范围
