Hello @ammu, can you provide any relevant command line settings or configuration options you've set? This error is common when the `apm-server.host` setting uses an IP that doesn't exist on the system. For example:

```auto
apm-server -E apm-server.host=1.2.3.4:8200 -e
...
ERROR	[beater]	beater/beater.go:142	failed to listen:listen tcp 1.2.3.4:8200: bind: can't assign requested address

```

To listen on all external interfaces specify `:8200` or `0.0.0.0:8200`. To listen on a specific interface, please ensure the IP plumbed matches your configuration.

HI @gil

Thanks a lot for the response.

Just wanted to know, where do I find this apm-server.host configuration file. I tried to locate but didn't find.

I do have done the relevant changes in apm-server.yml.

@ammu `apm-server.host` is the name of a config variable, not a file. In your apm-server.yml, you should have something like:

```auto
apm-server:
  host: "hostname:8200"

```

`13.233.140.23` is an EC2/AWS IP. If I recall correctly, public IP addresses are not seen by the instance; public IPs are NAT'd through to the instance via its private IP address.

If you want to expose your APM Server, then change the `host` value in apm-server.yml so it looks like this:

```auto
 apm-server:
  host: ":8200"

```

Hi @axw,

Correct I am using aws ec2 instance.

I got the point for  
**apm-server:**  
\*\* host: ":8200"\*\*. But my elastic is running on a different instance. How do I define the IP address of my elastic node in yml file ???

Instance 1 : kibana and APM  
Instance 2: Elastic.

@ammu To specify the IP address(es) of Elasticsearch, you need to configure `output.elasticsearch.hosts` instead. Please refer to [https://www.elastic.co/guide/en/apm/server/current/elasticsearch-output.html](https://www.elastic.co/guide/en/apm/server/current/elasticsearch-output.html).

Hi @axw,

Port 8200 is resolved. I appreciate your support.

Need one more help. Any idea of below error " [root@apmserver bin]# ./elasticsearch  
OpenJDK 64-Bit Server VM warning: If the number of processors is expected to increase from one, then you should configure the number of parallel GC threads appropriately using -XX:ParallelGCThreads=N  
OpenJDK 64-Bit Server VM warning: INFO: os::commit\_memory(0x00000000c5330000, 986513408, 0) failed; error='Cannot allocate memory' (errno=12)

# 

# There is insufficient memory for the Java Runtime Environment to continue.

# Native memory allocation (mmap) failed to map 986513408 bytes for committing reserved memory.

# An error report file with more information is saved as:

# logs/hs\_err\_pid3076.log

"  
It comes, when I am installing elastic.

Hi @ammu, you can specify the maximum heap size in the jvm.options file: [https://www.elastic.co/guide/en/elasticsearch/reference/current/heap-size.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/heap-size.html)

So if e.g your machine has 1Gb of RAM you can set -Xmx500mb

Hope this helps
