Configuring the Management Server¶

If you have installed PLOSSYS Output Engine with a separate management server or in a cluster, perform the following instructions on the management server.

Operating System Settings¶

In an editor, open the following configuration file:
```
/etc/sysctl.conf
```
Adjust the necessary operating system settings
- for high-volume systems:
```
net.ipv4.ip_local_port_range = 10000 65535
fs.file-max = 1058576
```
- for working with Elasticsearch:
```
vm.max_map_count = 262144
```

Elasticsearch¶

On the management server, edit the following file:

/opt/seal/etc/seal-elasticsearch/elasticsearch.yml

Add the following lines:

network.host: "0.0.0.0"
discovery.type: "single-node"

Save the file.
On the management server, edit the following file:
```
/opt/seal/etc/seal-elasticsearch/jvm.options
```
Set Max_Heap_Size to at least 50 % of the server's RAM.
```
–Xmx<ram_mb>m
–Xms<ram_mb>m
```
Example - 2048 MB
```
–Xmx2048m
–Xms2048m
```
Caution - value

<ram_mb> is the amount of RAM in Megabyte. You have to set –Xmx<ram_mb>m and –Xms<ram_mb>m to the same value, otherwise Elasticserach will not start.
Save the file.

Restart Elasticsearch:

sudo systemctl restart seal-elasticsearch

Kibana¶

In the /opt/seal/etc/kibana.yml file, activate the following setting:
```
server.host: "0.0.0.0"
```
Restart Kibana:
```
sudo systemctl restart seal-kibana
```
