Description Zeus and Prometheus do a game, Prometheus to Zeus a collection, the collection contains n positive integers, then Prometheus will be launched to Zeus m inquiry, each query contains a positive integer S, and then Zeus need to find in the collection A positive integer k, which makes K and S differ or result the most.

monitored hosts. The user provides the hostname or IP, as well as the user's email address, you can use 3 generate URLs to open, stop or delete your tracking. Notifications are sent whenever your server is down or in the background, and control URLs are included. 6 Actiontech Zabbix MySQL Monitor Percona monitoring Plugins Zabbix's Go language version, is a MySQL monitor plugin and template that is open source by love, integrates hundreds of performance monitoring metri

help to optimize it. Error monitoring is the statistic of the result of an incorrect request. Similarly, each request has a different error code, and we need to count the different error codes. In conjunction with the appeal police system, this type of monitoring allows us to perceive errors and intervene as early as possible. Saturation mainly refers to the load monitoring of the system CPU and memory. This type of monitoring can provide a basis for our capacity-expansion decisions. 2. Monito

useful, but there was some pitfalls. Here is some tips: Don ' t publish expensive functions. These can make expvar too expensive and even turn it to an accidental DoS vector Use verbose names. Err on the side of greater descriptiveness through verbosity. Beyond Expvar:more operable HTTP Endpoints You can also expose other information via HTTP: Health Handler Specialized handlers for libraries (e.g. Vault integration) Shutdown handlers (quit and abort) Admin Handlers:

the field of surveillance has been from the Zabbix of this 1.0 era, into the Integrated Monitoring solution of the 2.0 era. They began to choose a monitoring tool or solution based on STATSD technology. such as Datadog, boundary and other third-party monitoring service providers.The idea of these companies is to provide an integrated solution: how to integrate different operating systems, databases, middleware monitoring problems, you don't have to w

Objective In the K8S resource audit and billing this piece, the container and the virtual machine have very big difference. The container is not easy to implement relative to the virtual machine.Resource metrics can be collected using Heapster or Prometheus. Before the article has introduced, Prometheus Storage bottleneck and query large data volume, easy to oom these two problems. So I chose the heapster.

there's a metric there's a-means". Once you can repeatedly observe the balance of performance, performance problems are the best solution, but writing is the most difficult problem. In general, everyone in the company to Judge Metrics, there are monitoring tools. For our small team, or a team that embraces the community, this is basically a matter of not worth the candle. Because you have a lot of effort to write one, it is not as good as the community, it is very troublesome. So, we have embed

Recently in doing Prometheus monitoring, combined with Grafana to do front-end display, which involves memory time, there are many people on the memories of free and memory avaliable These two parameters are more confused, Here I use the Linux under the common view of memory usage of the free command, to do the next solution collation. Linux View memory usage, you can view/proc/meminfo and use the free command. root@

that the public can respond in real time to editorial responses to different articles. StackOverflow combines full-text search with geolocation and related information to provide more-like-this-related issues. GitHub uses Elasticsearch to retrieve more than 130 billion lines of code. Every day, Goldman Sachs uses it to process the index of 5TB data, and many investment banks use it to analyze stock market movements. But Elasticsearch is not just for large companies, it has also

who built the pyramid was a Prometheus (Prometheus) who stole fire from the heavenly house . Ancient and always without solution to the problem, along with the history of the archaeological excavation, again broke into the vision of civilization. How did the great masters of Science and Art, who built the pyramids, accomplish such masterpieces by what means? And how much of the wisdom and knowledge beyond

infrastructure developed by Golang. Prometheus, an early stage telemetry system is purely golang developed. Currently, stream processing takes Cassandra, but we are going to (almost) completely use Golang instead. We are also experimenting with HTTP streaming live services developed with Golnag. Many other small-product-oriented services. These projects are developed by about six teams, including more than 10 SoundCloud, most of whom

exit case, we may also be thousands of goroutine. If the Goroutine life cycle gets longer, we will instantly save up 100* thousands of goroutine, and if we don't, our service will crash instantly. So other people's problems may lead to failure of our own services. What to do? Use circuit breaker. We want to protect our services in this way: First set SLA (Service level agreement) Average response time Tolerance Rate Max QPS We need to monitor third-party service invocation error

Today, Human civilization (civilization) has been highly developed, if the first-class project, many people will say that Prometheus (Prometheus) for the human stole the fire. There is no doubt that the discovery of Fire (discovery) plays a vital role in the process of human civilization (vital), especially for those who eat raw food like me, the Fire is my Savior (Savior). Oh.However, if fire is a prime co
