【Nightingale Monitoring】Neptune——Categraf

Has anyone encountered the same confusion as me: When I use Prometheus to build a monitoring system, whenever there is a component that needs to be monitored, I have to add an exporter for it. If there are 10 components, I have to Adding 10 exporters, let alone the quality of these 10 exporters (because most of the exporters are developed by netizens themselves), the learning cost, deployment cost and maintenance cost are all a headache. Is there a component that can collect most indicators? Categraf is such a collector. Are you surprised or surprised? What is Categrf? Categraf is a monitoring and collection agent, similar to

[Nightingale Monitoring] Alarm management, great!

Monitoring is the method, alarming is the means, and solution is the purpose. However, have you ever encountered this kind of confusion? I have collected a lot of indicators, but I don’t know which indicators should trigger alarms, nor how to send these alarms to the corresponding teams or individuals, nor how to upgrade the alarms. When I used Prometheus+Altermanager before, I created a DingTalk group for each team, then added a bunch of tags, matched different tags and sent them to different groups. If I wanted to upgrade alarms, many times This is accomplished through threshold upgrade, but it is difficult to upgrade the same alarm through time. But Nightingale’s alarm rule management is not that complicated (they do the complicated things for you), and it’s also very elegant.

Business is growing exponentially, can usability construction be so stable?

1. Problems and Challenges As you can see from the figure, since 2017, vivo’s machine scale and number of services have grown significantly. In terms of machine scale, it has increased by about five times from 2017 to 2022, and the number of services has also basically increased by more than ten times. As the scale grows, challenges and complexity will definitely increase. Typical challenges in vivo are mainly divided into change challenges and failure challenges. 1. Change challenges There are still more or less manual change scenarios in the change; our single release time is relatively long; there are many scenarios of large-scale business migration; Google SRE has such a concept: 70% failure is caused by changes. Corresponding to vivo, this situation does exist. The change affects online stability.

Seven places to conduct automated security testing

Personally, I like DevSecOps (where security teams weave security throughout the entire process Dev and Ops are performing). Because of my passion, clients often ask me when, how, and where to inject various types of testing and other security activities. Below is a list of options I offer clients for automated testing (there is a lot more security work to do in DevOps - this is just automated testing). Together they analyze the list and decide where it makes the most sense based on their current state, and select tools based on their current focus. Seven Places for Automated Testing 1. In an Integrated Development Environment: Tools that check your code almost like a spell checker (not sure what this is called, sometimes called SAST) Agent Management and Dependencies

[Nightingale Monitoring] The Swiss Army Knife of Extracting Indicators from Logs

mtail is a Google open source tool that extracts metrics from application logs. It reads application logs in real time, then analyzes the logs through a script written by itself, and finally generates time series indicators. The project address is: https://github .com/google/mtail. Nightingale's Categraf also uses mtail to collect log indicators, but it has made some optimizations. We will slowly explain the specific optimizations. Now, let’s start with Google’s mtail, and then slowly talk about Nightingale’s mtail plug-in. The installation of mtail has given a brief introduction to mtail before, but in fact, that’s all. So, let's start directly with the installation. from ht

Smooth operation and maintenance, an iron pot

On June 5, Vipshop released a fault report on March 29, 2023. Due to the failure of the Nansha IDC refrigeration system, the Vipshop online mall stopped serving, causing hundreds of millions of losses (as a small operation and maintenance I'm trembling). For Vipshop, the online mall is its core business entrance, and failures are inevitable. However, it cannot be tolerated if the failure is so long. Why does this happen? In the eyes of small operations like us, this kind of accident should not happen in a company of this magnitude. We are all looking for ways to operate and maintain by imitating and learning from their PPTs. However, PPT is so advanced that it cannot prevent failures from occurring. Why is this? I personally would venture to make some guesses: PPT ≠ realistic fault drill = going through the motions? Live a good life, just talk

What capabilities should PG database operation and maintenance tools cover?

Before the holidays, I collaborated with the PG China community to conduct an online live broadcast on how to use D-SMART to operate and maintain the PG database. It happened that one of my clients in the financial industry listened to my introduction and called over to chat. They are selecting database Xinchuang and have tried several domestic databases. Finally, they are going to choose TDSQL. I felt a little surprised at the time. They had been selecting domestic databases since 2020, but it seemed that the initial experience after using TDSQL was not very good. Later, after communication, I learned that they had just started using TDSQL's distributed database and found that the research and development requirements were too high, so they all chose TDSQL's centralized MYSQL instance. After using it, they found that it was very easy to use. The entire database cloud

Operations and maintenance asked me to optimize the SpringBoot startup speed, and this is what I did!

SpringBoot is undoubtedly the largest framework for Java back-end development. Based on SpringBoot, there is a complete tool chain and various starters. For daily business development, it can be said that the wheels are complete. However, with the popularity of microservices and the cloud-native era, SpringBoot applications have exposed some problems, the most prominent of which are: slow startup applications, memory usage, and multi-cloud native applications that have relatively high startup speed requirements. When horizontal expansion is required, these new instances must be started within a short enough time to process new requests as quickly as possible. Cloud-native applications require as few resources as possible to run. Reducing the resources occupied by a single instance as much as possible means that

An in-depth explanation of the technology operation indicator system

Introduction When it comes to technology operation indicators, every technology person can name a few, such as transaction volume, response time, response rate, success rate, etc. These metrics are quantitative assessments of work in an area of operations. However, in order to evaluate the overall level of technology operations, it is necessary to establish an indicator system for technology operations, obtain overall information, and then use this information to drive the development of operations and achieve organizational goals. Construction Goals and Positioning Bank G has established a technology operation observability index system to provide managers with a multi-dimensional and refined operation management analysis framework, and use this as a starting point to improve the center's operation management capabilities, decision-making level and service quality. The construction of the indicator system follows the four principles of being quantifiable, comparable, action-oriented, and adaptable to multiple scenarios, focusing on actual business scenarios.

How to practice the 'four kings' of self-revolution

The operation and maintenance forum invites veterans in the operation and maintenance field to provide in-depth insights through interviews and manuscripts, and collide with each other in order to form some advanced consensus and promote the industry to move forward better. In this issue, we invited Wang Mingsong. Boss Wang put forward the "Four Rules" for cloud native application practice, which is widely recognized in the industry. Starting in 2019, all the IDC business of Boss Wang's company has been moved to the cloud. The scale is not small, but the SRE team is very small, a bit like NetFlix.
