Sending Elasticsearch to a syslog server
Posted on
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

fixing permission denied issue with udp 512 port graylog
Posted on
use iptables to pre-route NAT the udp port :
iptables -A PREROUTING -t nat -i eth0 -p udp –dport 514 -j REDIRECT –to-port 10515
This will bypass the limit in the OS to ports < 1024 to non=root users .

Installing sample data in elastic search
Posted on
After installing elastic search it is useful for testing and training to load some sample data.
1) create mapping :
curl -XPUT http://localhost:9200/shakespeare -d '
{
"mappings" : {
"_default_" : {
"properties" : {
"speaker" : {"type": "string", "index" : "not_analyzed" },
"play_name" : {"type": "string", "index" : "not_analyzed" },
"line_id" : { "type" : "integer" },
"speech_number" : { "type" : "integer" }
}
}
}
}
';
2) Load the data using the bulk api:
wget "https://github.com/ropensci/elastic_data/blob/master/data/shakespeare_data.json?raw=true" -O shakespeare.json curl -XPUT localhost:9200/_bulk --data-binary @shakespeare.json

VMWare vSphere ESXi v5.5 Install Errors disk cannot partition
Posted on
While adding a new disk to an ESX5.5. box it could not finish the partitioning stage and did not add to the Datastores.
Apparently ESX does succeed to clean up the Disk from the GUI.
NOTE: This procedure will destroy all data on the disk
