To configure the log level of the Golang application on the Debian system, you need to follow the following steps: Select the log library: First, select the appropriate log library. The Go standard library's log packages are simple to use, while third-party libraries such as logrus and zap provide more powerful features and performance. Set log level: Set the corresponding log level according to the selected log library. The settings of different libraries vary. The log package using the standard library logGo standard library does not directly support the log level, but can be simulated by custom output formats. The following example demonstrates how to control output based on a preset level: packagemainimport("log""os"

Select logging method: In the early stage, you can use the built-in error_log() for PHP. After the project is expanded, be sure to switch to mature libraries such as Monolog, support multiple handlers and log levels, and ensure that the log contains timestamps, levels, file line numbers and error details; 2. Design storage structure: A small amount of logs can be stored in files, and if there is a large number of logs, select a database if there is a large number of analysis. Use MySQL/PostgreSQL to structured data. Elasticsearch Kibana is recommended for semi-structured/unstructured. At the same time, it is formulated for backup and regular cleaning strategies; 3. Development and analysis interface: It should have search, filtering, aggregation, and visualization functions. It can be directly integrated into Kibana, or use the PHP framework chart library to develop self-development, focusing on the simplicity and ease of interface.

Integrate Go language log management tools on the Debian system. The steps are as follows: 1. Install the Go locale First, make sure that your Debian system has Go installed. If not installed, execute the following command: sudoaptupdatesudoaptinstallgolang-go Verification Installation: Goversion 2. Select logging tool Go language has a variety of logging tools, such as logrus, zap, zerolog, etc. This article takes logrus as an example. 3. Install logrus using goget command to install: gogetgithub.com/sirupsen/logrus IV. Configuration l

In CentOS, the system log files are mainly stored in the /var/log directory. Common ones include: 1./var/log/messages record system messages; 2./var/log/secure record authentication-related logs; 3./var/log/dmesg record kernel information; 4./var/log/cron record timing task information; 5./var/log/boot.log record startup process. CentOS7 and above use rsyslog to manage logs, combined with systemd's journald tool, can be viewed through the journalctl command. It is also recommended to use logrotate to rotate logs and real

The log level settings of the Debian system directly affect the system's operating efficiency, security and problem-solving capabilities. This article explains the Debian log level settings and their impact in detail. Log level Detailed explanation The log level determines the level of detailed information recorded by the system. The higher the level, the less information recorded, and vice versa. Common log levels (from low to high) include: emerg (emerg): system crashes and need to be handled immediately. alert: Serious problem, immediate action is required. crit: Critical error, affecting system functions. err(err): Error, but the system can still run. warning: potential problems that may lead to errors.

Selecting a log collection plan requires decision based on the project size and technology stack: small projects can use PHPMonolog to write file logs and push Filebeat; medium and large projects recommend ELK (strong functions but high resource consumption) or Loki Grafana (lightweight cloud native friendly) to achieve centralized monitoring; 2. Common challenges in building an alarm system include large log volume, false alarm missed, alarm fatigue and inconsistent format. The response strategies are log hierarchical filtering sampling, refined threshold and aggregate alarms, hierarchical notification rotating mechanism, unified JSON log specification; 3. In addition to error logs, PHP health monitoring should also pay attention to request response time, CPU/memory/disk/network usage, database connections/slow query/QPS, cache hit rate, P
