Sending Elasticsearch to a syslog server

Posted on by admin

yum install rsyslog -y

Add the following to rsyslog.conf on the client system

############

$ModLoad imfile
$InputFileName /var/log/elasticsearch/elasticsearch.log
$InputFileTag elasticsearch
$InputFileStateFile stat-elasticsearch
$InputFileSeverity Info
$InputFileFacility daemon
$InputRunFileMonitor
#local3.* hostname:<portnumber>

daemon.* @192.168.1.66:514


############

 

Also if you want all logs to go through to syslog server:

 

*.* @192.168.1.66

 

at the end of the file.

Issue a :

service rsyslog restart

and watch the logs flow in.

Measuring Apache bandwidth from a bash script

Posted on by admin

So reason : double checking Sawmill and AWstats.

(sawmill won..)

echo “$(awk ‘{print $10}’ prd.logs | grep -v “-” | paste -sd + – | bc )/1024/1024/1024″ | bc

result is in GB.
