I'm new to ELK, and I am trying to set up multiple index sources (from netflow sources and from snmp via collectd). Seems like the info polled from SNMP is missing ...fields don't show up) I have the following setup:

CentOS 7  
collectd-5.5.1-2.el7.x86\_64 (polling for snmp)  
logstash-1.5.4-1.noarch  
elasticsearch-2.2.1-1.noarch  
kibana-4.4.2-1.x86\_64

When I upstart logstash from systemctl it starts fine, but it looks like no data is being pushed into ES. If I manually run logstash pointing to the conf file data is populated normally into ES.

Here is my logstash config:  
`input {  
udp {  
port =\> 9997  
codec =\> netflow {  
definitions =\> "/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-codec-netflow-1.0.0/lib/logstash/codecs/netflow/netflow.yaml"  
versions =\> [5]  
}  
}  
udp {  
port =\> 25826 # Must be specified. 25826 is the default for collectd  
buffer\_size =\> 1452 # Should be specified. 1452 is the default for recent versions of collectd  
codec =\> collectd { } # This will invoke the default options for the codec  
type =\> "collectd"  
}  
}

filter {  
mutate {  
convert =\> {  
"[netflow][ipv4\_src\_addr]" =\> "string"  
"[netflow][ipv4\_dst\_addr]" =\> "string"  
}  
}  
geoip {  
source =\> "[netflow][ipv4\_src\_addr]"  
target =\> "src\_geoip"  
database =\> "/etc/logstash/GeoLiteCity.dat"  
}  
geoip {  
source =\> "[netflow][ipv4\_dst\_addr]"  
target =\> "dst\_geoip"  
database =\> "/etc/logstash/GeoLiteCity.dat"  
}  
#mutate {  
#convert =\> ["[geoip][coordinates]", "float"]  
#}  
}

output {  
stdout { codec =\> rubydebug }  
if [type] == "collectd" {  
elasticsearch {  
index =\> "logstash\_collectd-%{+YYYY.MM.dd}"  
host =\> "localhost"  
protocol =\> http  
}  
} else {  
elasticsearch {  
index =\> "logstash\_netflow-%{+YYYY.MM.dd}"  
host =\> "localhost"  
protocol =\> http  
}  
}  
}`

Can anyone help?

What do the logs show for LS? Are you sure the process us running after start?

I was able to get it working. Unfortunately I don't know how, but effectively it was a series of restarts to collectd, LS and ES.
