PostgreSQL rsyslog的使用

摘要: PostgreSQL使用rsyslog将日志传送到远端机器

一、服务端

1. 安装syslog包

$ sudo yum install -y rsyslog

2. 创建目录

sudo mkdir -p /export/postgreslog/

3. 配置

$ sudo vim /etc/rsyslog.conf
# Provides TCP syslog reception
$ModLoad imtcp.so
$InputTCPServerRun 514

#### GLOBAL DIRECTIVES ####
$MainMsgQueueSize 500000
$MainMsgQueueDequeueBatchSize 128
$MainMsgQueueDiscardMark 20000
$MainMsgQueueHighWaterMark 16000
$MainMsgQueueLowWaterMark 4000

$EscapeControlCharactersOnReceive off

# Use default timestamp format
$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat
# log format
$template pgFormat,"%msg:R,ERE,2,DFLT:^ \[[0-9]+-[0-9]+\] (#011)?(.*)--end%\n"
# logfile name
$template PostgresLogFile,"/export/postgreslog/%hostname%_%programname%/%$year%-%$month%-%$day%/postgresql-%$year%-%$month%-%$day%-%$hour%.log"

# collect log of local0
local0.* ?PostgresLogFile;pgFormat

4. 启动

$ sudo /etc/init.d/rsyslog restart

二、客户端

1. 安装syslog包

$ sudo yum install -y rsyslog

2. 配置rsyslog

sudo vim /etc/rsyslog.conf
EscapeControlCharactersOnReceive off
local0.* @@rsyslog_server:514

3. 启动rsyslog

$ sudo /etc/init.d/rsyslog restart

4. 配置 postgresql.conf

$ vim postgresql.conf
log_destination = 'syslog'
syslog_facility = 'LOCAL0'
syslog_ident = 'pg-test'

5. reload配置

# select pg_reload_conf();
