【gala_gopher】tcp_link探针相关指标计算有误

1、部分指标数据无法正常在prometheus获取,包括:rtt、rtt_max、rcv_wnd_min、rcv_wnd_avg、rcv_wnd_max、filter_drops、backlog_drops、md5_hash_drops、sk_drops、ofo_count。
初步定位:meta文件中指标的type未设置

2、tgid与process_name匹配有问题

3、从prometheus观察的link_count数据统计有问题,在没有打流的场景下,每个周期(5s)数值增加接近一万。
初步定位:累积计算方法出错
输入图片说明
类似问题的指标还有:packets_in、packets_out、rx_bytes
