What's wrong with my logback syslog appender?

阅读更多关于 What's wrong with my logback syslog appender?

问题 I'm trying to get a logback syslog appender working, and I've definitely got something misconfigured. I've created a small sample project which I think should log to syslog, yet it doesn't. I'm sure I'm missing something stupid. Here's the appender from logback.xml: <appender name="SYSLOG" class="ch.qos.logback.classic.net.SyslogAppender"> <syslogHost>localhost</syslogHost> <facility>USER</facility> <suffixPattern>[%thread] %logger %msg</suffixPattern> </appender> I've tried adding the port

Using syslog in rails application

问题 I am thinking of using syslog in my rails applications. The process is outlined in this blog post: Add gem 'SyslogLogger' to your Gemfile Add require 'syslog_logger' to the top of config/environments/production.rb Also uncomment the config.logger = line in the same file. In production box I have 4 rails applications running using passenger. If I switch to use syslogger for all 4 of my applications then I am afraid that the log messages from all 4 applications will go to a single file and the

Does Syslog really have a 1KB message limit?

阅读更多关于 Does Syslog really have a 1KB message limit?

问题 It seems Syslog has a 1KB message limit. Is this hardcoded into the Syslog protocol, or is this a parameter that can be set for each server? I am hoping the article I read was out of date, so if you have any info please share. 回答1: This is correct, as can be seen in the syslog protocol RFC. This, and other deficiencies in the syslog protocol, is the reason why modern syslog daemons such as rsyslog support enhanced protocols with features such as TCP transport, encryption etc. There was also

初识 MySQL 5.6 新功能、参数

阅读更多关于初识 MySQL 5.6 新功能、参数

背景：继上次介绍初识 MySQL 5.6 新功能、参数完之后，刚好MySQL 5.7又GA了，在官方测试里看到，MySQL5.7在功能、性能、可用性、安全和监控上又提升了很高。现在看看和MySQL5.6对比，看多了哪些参数：（后续不定时更新）参数： 1： binlog_group_commit_sync_delay 全局动态变量，单位微妙，默认0，范围：0～1000000（1秒）。表示binlog提交后等待延迟多少时间再同步到磁盘，默认0，不延迟。设置延迟可以让多个事务在用一时刻提交，提高binlog组提交的并发数和效率，提高slave的吞吐量。 2： binlog_group_commit_sync_no_delay_count 全局动态变量，单位个数，默认0，范围：0～1000000。表示等待延迟提交的最大事务数，如果上面参数的时间没到，但事务数到了，则直接同步到磁盘。若 binlog_group_commit_sync_delay 没有开启，则该参数也不会开启。 3： check_proxy_users 全局动态变量，默认关闭。表示是否开启代理用户的功能，后面会在安全性上面会介绍。 4： default_authentication_plugin 全局变量，默认 mysql_native_password，可选：sha256_password

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 1 设置错误日志 NGINX将遇到的不同严重级别的错误信息记录到错误日志。 error_log 指令设置记录错误信息到指定文件、 stderr 或 syslog 和最小严重级别。默认，错误日志位于 logs/error.log （绝对路径取决于操作系统和安装方式），所有严重级别的消息都会被记录。下面配置，将错误消息的最小严重级别从 error 改为 warn ： error_log logs/error.log warn; 在这种情况下， warn 、 error 、 crit 、 alert 和 emerg 级别的消息被记录。错误日志默认全局范围开启。在 main （顶级）配置上下文中定义 error_log 指令覆盖该行为。 main 上下文的设置总是被其它配置级别继承。 error_log 指令也可以在 http 、 stream 、 server 和 location 级别指定，覆盖从更高级别继承的设置。在一个错误的情况下，只记录一条最接近错误发生级别的错误消息到错误日志。然而，如果相同级别指定多个 error_log 指令，消息写入错误指定的日志。 2 设置访问日志 NGINX在请求处理之后记录客户端请求的访问日志。默认访问日志位于 logs/access.log

How to verify rsyslog TCP communication with the server from the client side?

阅读更多关于 How to verify rsyslog TCP communication with the server from the client side?

问题 I want to be able to know if all of the servers that I am logging to are properly receiving my TCP messages and answering back. I don't want to have to implement anything else on the server side, just want to monitor everything in the client machine. I want to be able to do something like a ping test but valid for a rsyslog environment, using its protocols and ports. I also know that there is a "debug" file but I believe its too much complicated to actually debug. 回答1: impstats can give you
