What is awkAwk is a small programming language and command-line tool. (its name is from the first letter of its founder Alfred Aho, Peter Weinberger and Brian Kernighan's surname). It is well suited for log processing on the server, primarily because awk can manipulate files, often building lines in readable text.I say it applies to servers because log files, dump files, or any text-formatted server that terminates dumps to disk can become very large, and you will have a large number of such fil

For example, when you are running Tomcat, do not leave unused web programs that are not maintained. Make sure that they do not run as root.

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 a shovel out of a storage room, booking an e

Case
The following illustration gives you a general idea of Spring XD.
The Spring XD Team believes that there are four main use cases created for creating large data solutions: data absorption, real-time analysis, workflow scheduling, and export.
Data absorption provides the ability to receive data from a variety of input sources and transfer it to large data repositories, such as HDFs (Hadoop file system),
challenges such as storage, security, and monitoring. In the field of monitoring, the container quasi-data analysis platform from vendors such as Splunk and sumo logic is particularly appealing. They can bring better visibility into containerized infrastructure.
From an ecological point of view, another notable consideration is the discussion of the Docker branch. Red Hat's new Ocid project has made some people think that the Docker branch has appear

This is not a particularly bad practice, but it is very bad if you keep log data and your product data in a database.Perhaps your log records are very conservative, and each Web request produces only one log. For each event of the entire Web site, this still generates a lot of database insertions, competing for the da

Alert queue polling Interval. This setting is the number of milliseconds for the alert service to wait between processing batches of alerts.

Alert settingsThe alert settings of smokeping are a bit complicated, but they are easy to use and well considered.By default, it can use emails for alert, or directly call external programs for im alarms. That is to say, you only need to write a simple script, in this way, you can implement the smokeping of MSN, Gtalk, fetion, and other IM and SMS alarms.

Use Anko and Kotlin to implement the dialog box and warning prompt (KAD 24) on Android and ankokotlin
By Antonio Leiva
Time: Mar 9 and 2017

Using Builder, creating warning prompts and dialog boxes in Android is relatively simple. However, due to the complicated language, some prompts are usually vague.
In Kotlin, only Lambda expressions can help us understand how code is handled.
However, with Anko, we can make it easier. In this a

Internal method:
Dom. require ("Lang"); Dom. require ("Oop") var person = Dom. OOP ({init: function (name) {This. name = Name ;}, secret: function () {return 'I sometimes like girly drinks ';}. protect (), // defines it as an internal method. Only describe: function () {return "Hi, I'm # {name} can be called internally }. # {secret }. I
