IntroducedMetrics is a package of metrics for Java services, embedded in Java code Metrics code, you can easily monitor the business code of the various indicators, at the same time, metrics can be very good with ganlia, graphite combination, Easy to provide graphical interface. The basic use of the core package (currently stable version 3.0.1) directly into the Pom file can be configured as follows: Dependency > groupId >com.codahale.metricsgroup

always registers all your metrics as JMX mbeans. You can view them directly through jconsole or visualvm. For details, see the following.Console mode. Metrics provides consolereporter, which periodically prints the registered metric to the console.In the csv format, metricsuses csvreporter, and cyclically stores a series of. CSV files. There are other reporter, such as sending data to a ready-made monitoring platform such as ganlia or graphite.Ganliareporter returns the metrics to the ganglia

questions such as "What the user Wants" and "how to embody the content priority". There is a great need for collaborative discussions at this stage. I will share the sketches with customers, managers, project colleagues and other designers. If necessary, we will pause for a moment and draw one or two sketches before the user for testing. Then repeat this phase to refine, iterate, and deduce the sketch. Once the direction of the sketch is clear, I will draw a formal hand-drawn manuscript. Like

yourself using timed tasks to delete data from a table that is valid for only one hour, day, or weeks, you are not looking for the right way to do things. Using Redis,statsd/graphite, Riak, they are all more appropriate tools for doing this kind of thing. This recommendation also applies to data collected for those short life periods.Of course, it's also possible to plant potatoes in the back garden with an excavator, but it's much slower than taking

these at the Sentinel's core anymore, but a sample use case is that we want to minimize concurrency and simple operations if things seem to be already running. This is useful for a cron-like task that may need to be performed every once in a while without strong coordination.This use of SETNX operations in Redis is quite simple: From contextlib Import contextmanagerr = Redis () @contextmanagerdef Lock (Key, nowait=true): While not r.setnx (key, ' 1 '): if nowait: raise Locke
