ops-agent

ops-agent

基于open-falcon二次开发的linux监控客户端

特性

• 代码重构、移除无用的接口和配置信息;
• 重写url metric的probeUrl方法, 使用go http库替代使用系统curl命令来探测url;
• 重写/plugin/update接口, 使用go-git库替代使用系统的git命令来更新插件仓库;
• 新增从私有git仓库同步插件功能;
• 新增运行日志配置, 支持日志滚动;
• 新增/metrics接口, 支持查看当前监控的所有metric;
• 新增/metric/check接口, 支持查看当前系统metric依赖环境;
• 新增cpu核心绑定、内存阈值配置; 当agent内存达到阈值的50%时, 打印告警信息；当内存达到阈值的100%, 程序直接退出;
