Hello,

I installed collectd, logstash, elasticsearch and kibana. 😁  
I'd like to generate stats from collectd and send them to ec via logstash.  
It dosen't work.  
Here are my conf files :

logstash.conf  
_input {_

- udp {\*
- port =\> 25826 # 25826 matches port specified in collectd.conf\*
- buffer\_size =\> 1452 # 1452 is the default buffer size for Collectd\*
- codec =\> collectd { } # specific Collectd codec to invoke\*
- type =\> collectd \*
- }\*  
_}_  
_output {_
- elasticsearch { \*
- }\*  
_}_

collectd.conf

\*# For each instance where collectd is running, we define \*  
_# hostname proper to that instance. When metrics from_  
\*# multiple instances are aggregated, hostname will tell \*  
_# us were they came from._  
_Hostname "ilos-stats"_

- 
  - 

_# Fully qualified domain name, false for our little lab_  
_FQDNLookup false_

- 
  - 

_# Plugins we are going to use with their configurations,_  
_# if needed_  
_LoadPlugin cpu_

- 
  - 

_LoadPlugin df_

- 

```
   Device "/dev/sda1"*

```

- 

```
   MountPoint "/"*

```

- 

```
   FSType "ext4"*

```

- 

```
   ReportReserved "true"*

```

- 
  - 

_LoadPlugin interface_

- 

```
   Interface "eth0"*

```

- 

```
   IgnoreSelected false*

```

- 
  - 

_LoadPlugin network_

- 

```
   <Server "localhost" "25826">*

```

- 

```
   </Server>*

```

- 
  - 

_LoadPlugin memory_

- 
  - 

_LoadPlugin syslog_

- 

```
   LogLevel info*

```

- 
  - 

_LoadPlugin swap_

- 
  - 

_\<Include "/etc/collectd/collectd.conf.d"\>_

- 

```
   Filter ".conf"*

```

I would recommend using the `stdout` output with `codec => rubydebug` to troubleshoot this. It will immediately become apparent if data is or is not flowing through Logstash. You may also want to invoke Logstash with the `--verbose` flag, or even the `--debug` flag (warning: Debug throws a LOT of data).

That said, I do not see any glaring errors in your logstash.conf setup.

I'll second that.

Also it's useful if you format configs etc using the "Preformatted text" button 🙂
