I have introduced the use of zabbix monitoring fixed port 3306 mysql Article address for http://dl528888.blog.51cto.com/2382721/1346590), there is a bad place is only monitoring fixed port 3306, if it is not 3306 port, You need to modify the template, if the host has multiple mysql instances, you need to have different mysql templates and manage the monitoring. To solve this problem, I use lldlow level discovery to monitor mysql, you only need to mark

People familiar with Exchange know that Outlook 2003 clients do not support automatic discovery of exchange, but there is a particularly simple way to verify this. After we open the Outlook 2003 client, install the CTRL key, and then left-click the Outlook 2003 icon in the out-of-the-box menu that does not see the option to test auto-discovery. 。 650) this.width=650; "title=" clipboard "style=" Border-top:0

Zabbix's "template OS Linux" Templates support monitoring mounted disk space utilization, which is implemented using LLD (low-level discovery) without disk IO monitoring. This article describes the method of monitoring disk IO using the Zabbix LLD function.idea : First create discovery rules, configure the corresponding userparameter on the agent side, invoke the well-written shell script, dynamically find

About Spring CloudSpring Cloud is a spring boot-based cloud application development tool for configuration management, service discovery, circuit breakers, intelligent routing, micro-agents, control buses, global locks, decision-making campaigns, Operations such as distributed sessions and cluster state management provide a simple way to develop.Spring Cloud contains multiple sub-projects (for many different open source products involved in distribute

Summary: Contour discovery is a method based on image edge extraction to find the contour of an object, so the threshold selection of edge extraction affects the final contour discovery results.The code is as follows:ImportCv2 as CVImportNumPy as NPdefContours_demo (image): DST= CV.

Spring Cloud Eureka is the Service governance module under the spring Cloud Netflix project. The spring cloud Netflix project is one of Spring cloud's sub-projects, primarily packaged with Netflix's range of open source products, which provides a self-configuring Netflix OSS integration for spring boot applications. With some simple annotations, developers can quickly configure common modules in the application and build large, distributed systems. It mainly provides modules including: Service

Core Data Structures: Nodetable class is responsible for Ethereum node discovery, Nodetable uses Kademlia (KAD) algorithm for node Discovery Nodetable maintain a list of network nodes, this list is the currently available node for use in the upper layer The hash generated by the Nodeid after SHA3 is 256 bits. The list has 256-1 = 255 items, where 1 is because shaving has a node bucket (nodebucket) for each

The Discovery protocol can use the Neighbor Discovery Protocol to discover a neighboring router and use it as its own default gateway. The node uses the Neighbor Discovery Protocol to actively track whether the neighbor is reachable and detect the change of the neighbor data link layer address. When the router or the path to the router fails, the host actively se

In IPv6, the characteristic performance is IPv6 Neighbor Discovery. Then we will introduce the specific meanings and structural functions in this article. One of the advantages of IPv6 is its flexible routing mechanism. Because the IPv4 network ID is assigned, a router located on the Internet hub is required to maintain a large route table. These routers must know all the routes to forward data packets that may be directed to any node on the Internet.

Service Discovery System consul1. What is consul? Is a service management software. Supports distributed, highly available, service discovery, and configuration sharing in multiple data centers. Consul supports health check and allows storage of key-value pairs. Consistency protocols use the Raft algorithm to ensure high service availability. The GOSSIP protocol is used for member management and message bro

Generally, after the zabbix server and client are deployed, it is complicated to manually add hosts to the Host group if there are too many hosts. Today, we will introduce zabbix's automatic discovery function. 1. Before automatic configuration discovery, the server needs to modify the following configurations: [[Email protected] ~] # Vim/usr/local/zabbix/etc/zabbix_server.conf fpinglocation =/usr/sbin/fpi

1, low-level automatic discovery overviewZabbix's low-level Autodiscover (LLD) is suitable for monitoring multiple instances, monitoring changes in data (partitions, network cards).Automatic Discovery (LLD) provides a way to automatically create monitoring items, triggers, and graphics for different entities on your computer. For example, Zabbix can automatically start monitoring file systems or network int

data is difficult. The current industry mainly relies on process control, manual maintenance and automatic discovery to solve the problem of fresh and accurate data. Process Control and human maintenance are not involved, since we are human beings, not "God", it means "lazy", will be wrong. In this information explosion of the big data era, and then rely on human operations, we have been hurt. Therefore, the key to accurate data is to rely on automat

I have introduced redis using zabbix to monitor fixed port 6379 (article address is http://dl528888.blog.51cto.com/2382721/1361407), there is a bad place that only monitoring fixed port 6379, if it is not port 6379, you need to modify the template. If the host has multiple redis instances, you need to have different redis templates and manage monitoring. This is very troublesome. To solve this problem, I use lld (low level discovery) to monitor redis.

Zabbix can manually add agent client, when the number of hosts more than a long time, then the manual duplication of work will greatly increase. Zabbix's auto-discovery feature can help us solve this problem.Preparation conditions:1.
