NVD Backlog Tops 20,000 CVEs Awaiting Analysis as NIST Prepares System Updates
NVD’s backlog surpasses 20,000 CVEs as analysis slows and NIST announces new system updates to address ongoing delays.
zipkin主要关注三个属性:
traceId:用于跟踪整个服务
spanId:每一个单独的服务有一个新的spanId
parentSpanId:如果是由其它的服务调用,指向调用服务
假设用户访问页面A,服务器响应这个请求,在接收到请求的时候,生成了记录A{traceId : TA, spanId : SA},生成A页面的数据,需要调用B服务,从数据库获取数据,则根据记录A,生成记录B{traceId : TA, spanId : SB, parentSpanId : SA},如果还有其它的服务,也如此,最终就可以根据traceId,spanId,parentSpanId来生成一个服务的调用时间线。
var traceA = zipkin.trace('A');
// A服务调用的东西
setTimeout(function(){
var traceB = zipkin.childTrace('B', traceA);
setTimeout(function(){
// B服务相关的一些参数记录
traceB.done({
code : 'xxx'
});
// A服务相关的一些参数记录
traceA.done({
name : 'xxx'
});
});
}, 1000);
