我是靠谱客的博主优秀发卡，最近开发中收集的这篇文章主要介绍CentOS6u9 Zabbix2.2安装配置监控告警（四）Template OS Linux模板小结，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

简单说明：

本博文是对zabbix_get命令-k参数可用的检测关键字的简单总结归纳
这些关键字通过查看Template OS Linux模板获得
这里写图片描述

测试命令说明：

# Server端信息
SERVER_IP=192.168.1.10
SERVER_PORT=10051
# Agent端信息
AGENT_IP=192.168.1.11
AGENT_PORT=10050
zabbix_get
# -s 指定agent的IP
# -p 指定agent的PORT
# -I 指定zabbix服务端IP
# -k 指定检测关键字

系统时间相关的测试关键字：

# Template OS Linux: Host boot time
zabbix_get -s ${AGENT_IP} -p ${AGENT_PORT} -I ${SERVER_IP} -k system.boottime
# Template OS Linux: Host local time
zabbix_get -s ${AGENT_IP} -p ${AGENT_PORT} -I ${SERVER_IP} -k system.localtime
# 这两个测试返回UNIX时间戳，可以使用date命令转换
date +%F_%T -d @$(zabbix_get -s ${AGENT_IP} -p ${AGENT_PORT} -I ${SERVER_IP} -k system.localtime)
# Template OS Linux: System uptime
zabbix_get -s ${AGENT_IP} -p ${AGENT_PORT} -I ${SERVER_IP} -k system.uptime
# 监控系统启动了多少秒，如果该数据不刷新，则激活触发器：
# Template OS Linux:{HOST.NAME} has just been restarted

内核配置相关的测试关键字：

# Template OS Linux: Maximum number of opened files
zabbix_get -s ${AGENT_IP} -p ${AGENT_PORT} -I ${SERVER_IP} -k kernel.maxfiles
