我需要将计数器和仪表导出到csv,以便稍后处理它们。通过使用gradle,我获得了codahale指标的罐子3.1.2:
LIKE '%$state%' group by
对于csv导出,我使用以下代码行创建了一个记者:
let fileManager = NSFileManager.defaultManager()
// We need just to get the documents folder url
let documentsUrl = fileManager.URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)[0] as NSURL
do { let directoryUrls = try NSFileManager.defaultManager().contentsOfDirectoryAtURL(documentsUrl, includingPropertiesForKeys: nil, options: NSDirectoryEnumerationOptions.SkipsSubdirectoryDescendants)
} catch {
let directoryUrls = documentsUrl
}
let video = AVAsset(URL: directoryUrls)
let AVThumbnailAsset = AVAssetImageGenerator(asset: video)
let time = CMTimeMakeWithSeconds(1.0, 1)
var actualTime : CMTime = CMTimeMake(0, 0)
let myImage: CGImage
let convertedImage: UIImage
do{
myImage = try AVThumbnailAsset.copyCGImageAtTime(time, actualTime: &actualTime)
convertedImage = UIImage.init(CGImage: myImage)
} catch {
print("This is the Error")
print(error)
convertedImage = UIImage(named: "2.35:1")!
}
videoThumb.image = convertedImage
我可以看到文件已创建,它们包含时间戳和值(在此示例中,为量表设置了值):
polymer
唯一的问题是文件会重复最后一个值,直到我使用webcomponents
覆盖它。在这种情况下,我将标准值设置为References
一次,等待几分钟,然后设置新值Angular2 & Polymer
。
这使得难以解析csv并自己创建平均值或创建直方图,因为我不知道compile('io.dropwizard.metrics:metrics-core:${metricsVersion}' )
compile('io.dropwizard.metrics:metrics-annotations:${metricsVersion}' )
是否已提交一次或三次。
我看过这些SO帖子,但它们并没有帮助我解决我的问题:
答案 0 :(得分:1)
所有这一切都是基于我方的误解:Spring Boot提供的指标只允许使用gauge
或counters
。两者都没有计算平均值。
为了访问我需要的东西,我必须获得对底层Codahale指标注册表的访问权限:
@Autowired
MetricRegistry metricRegistry;
然后我可以在我的代码中启动和停止计时器:
Context timer = metricRegistry.timer("foo").time();
// do whatever needs to be timed
timer.stop();
这些值将由CsvReporter导出到名为timer.foo.csv
的文件中,该文件包含以下值:
t,count,max,mean,min,stddev,p50,p75,p95,p98,p99,p999,mean_rate,m1_rate,m5_rate,m15_rate,rate_unit,duration_unit
