ObjectiveAs an operations engineer, viewing the analysis system log is a daily homework, but every time you look at the log is a server one server to see, several servers can also deal with this, but if you manage hundreds of thousands of online servers, this method is stretched. So we need to use the log server, but how can it be more intuitive to display it? Loganalyzer is a good choice, this article will explain how to use rsyslog+loganalyze to ach

Shell code root @ viscent:/var/log # lsof | grep messages rsyslogd 544 syslog 7 w REG 8, 1 214641 134422/var/log/messages can be seen from the command output above, the PID of the process that opened the/var/log/messages file is 544, and the file descriptor (FD) of the file/var/log/messages is 7. Based on the above PID and FD, you can find the corresponding file in/proc: Shell code root @ viscent: /var/log # ls-al/proc/54

This is my entire process of log analysis for haproxy in the unit.We have been in the maintenance ES cluster configuration, and did not put a set of processes including the collection end of the code, all their own once, and the online collection of logs when we generally use the logstash, but the industry many people say logstash whether it is performance and stability is not very good, The advantage of Logstash is the simple configuration, this time I chose the RsyslogToday this haproxy log, I

daemon.Since I first learned about the syslog, I don't know where the log output of the fastcgi process is. I checked the output to/var/log/messages. However, there are no messages files in this directory.This is because the config file for syslog is not configured.The/etc/syslog.conf file is a configuration file for the Linux journaling system.

. Filter (log filter)Filter is a highlight of rsyslog, and usually we don't have all the logs to collect, such as we only need to error The following level of log, or we want to include a specific content of the log. With the use of filter, we can easily implement these requirements. Here are a few examples of how to use the Manual in detail: 12 :msg, contains,"test_message"/var/log/test.log~ If the log content contains

I. Introduction of LoganalyzerThe Loganalyzer tool provides an easy-to-use, powerful front-end for searching, viewing and analyzing network activity data, including system logs, event logs, and many other log sources. Since it only presents the data to our users, the data itself needs to be collected by another program, such as Syslogd,rsyslog (which is now the default syslogd for the distribution), Winsyslog or Monitorware proxy. Loganalyzer is also

network segment information forwarding, it supports the host chain, even if the log message after a lot of computer forwarding, can also find the original host address and the entire forwarding chain. A final design principle is to make the configuration file as powerful and concise as possible. As an alternative to syslog, Syslog-ng is a complete replacement for syslo
