How to write queries Generating Queries Figuring out how to write queries is probably the most difficult part of using jmxtrans, but once you get the hang of it, it really isn't that difficult.
Below is an image of JConsole looking at the metrics provided by Ehcache which is a commonly used object caching library for Java. As you can see, I've marked in red a few areas of note. That is because we are going to create a query for 3 attributes "CacheHits", "CacheMisses", "ObjectCount" from all of the available caches (there is only one shown ClientCache). The "obj" field can be discovered by clicking on the MBean itself ( ClientCache in this case) and selecting the ObjectName field.
Here is some example json that queries one server, w2, on port 1099: You can see the use of a wildcard * as part of the obj configuration. Thus, the final output writting to the keyout2.txt file will look like this: "obj" : "net.sf.ehcache:type=CacheStatistics,*", "resultAlias": "ehcache" Otto. Introduction Otto is an event bus designed to decouple different parts of your application while still allowing them to communicate efficiently.
Forked from Guava, Otto adds unique functionality to an already refined event bus as well as specializing it to the Android platform. Usage. ZeroTier. Voxxit/dockerfiles. Voxxit/osquery.

A production ready Docker workflow. Part 4: Service Discovery and LB. This is the final part of a series of posts about how we're using Docker in production at IIIEPE. If you haven't, please read Part 1, Part 2 and Part 3 before continuing.
In this post, I'll discuss how we configured Service Discovery and the load balancer. Service Discovery There's plenty of Service Discovery solutions out there, but we only tested etcd and Consul.io. Etcd is part of CoreOS, and while you can use it without CoreOS, you soon realise that you need to learn more than just etcd. Before I dig deeper, in case you don’t know what Service Discovery is, let me say that it has nothing to do with load balancing, is just a piece of software that knows about the current state of (in this case) the containers running across the infrastructure. Like any Service Discovery tool, Consul.io solves one problem, it stores the IP, port and state of an application.
Since both Consul.io and Registrator run inside Docker containers, implementing both was even easier than we thought. Load balancer. Luiselizondo (Luis Elizondo) Concurrency Kit. 20 Best Free Tutorials to Learn Python: PDFs, eBooks, Online. Python is one of the most elegant and complete programming language and comes packed with tons of features to develop web applications as well as applications that run on your computer. Python is high level language, simple to learn and comes with multiplatform support. The depth of Python makes it specifically useful in education and research sector and that is one reason for Python’s popularity among students. There is no dearth of Python tutorials out there in the wild that train you on fundamentals of coding in Python, but finding the right set of tutorials is crucial to master the concepts fast with lesser effort.
One can learn Python basic concepts within an hour by following a good Python tutorial or spend hours struggling with a low quality learning material. In an attempt to make it easier for everyone to find the right Python tutorials, I have listed down various Python tutorials and learning resources, each labelled by complexity and delivery media. 1. List of Free And Open Source Monitoring System. The Linux monitoring systems are often used to follow system resources, such as CPU load, the amount of free RAM, network traffic statics or memory consumption. Which are ones from the most important tasks for every administrators. Furthermore, those tools notify the network administrator (via email, SMS or other alarms) when something interrupts or goes down which makes their life easier.
Programming on Flipboard. Git ready » learn git one commit at a time. Kernel bypass. In two previous posts we've discussed how to receive 1M UDP packets per second and how to reduce the round trip time. We did the experiments on Linux and the performance was very good considering it's a general purpose operating system. Unfortunately the speed of vanilla Linux kernel networking is not sufficient for more specialized workloads. For example, here at CloudFlare, we are constantly dealing with large packet floods. Vanilla Linux can do only about 1M pps. This is not enough in our environment, especially since the network cards are capable of handling a much higher throughput.
CC BY 2.0 image by Tony Webster It's apparent that the only way to squeeze more packets from our hardware is by working around the Linux kernel networking stack. The kernel is insufficient.

Today at its Google I/O conference, the company announced Brillo, the "underlying operating system for the internet of things," with a developer preview coming in Q3 of this year. Brillo is "derived" from Android but "polished" to just the lower levels. It supports Wi-Fi, Bluetooth Low Energy, and other Android things.
Additionally there's Weave, the (cross platform) common language that will let Brillo devices, phones, and the internet all talk to one another — that's coming in Q4.
