Configuring a PLOSSYS 5 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
```

Logging¶

If you have installed PLOSSYS 5 with a separate management server, you have to set the IP address of the management server for the logging:

On the PLOSSYS 5 server, edit the following file:
```
/opt/seal/etc/filebeat.yml
```
In elasticsearch, replace localhost by the host name or IP address of the management server:
```
output:
  elasticsearch:
    hosts:
    - http://<admin_server>:9200
```
Save the file.
In the seal-rest service, specify the following key:
- ELASTICSEARCH_REST_URL: URL of the Elasticsearch server
Example of setting the key via PLOSSYS CLI
```
plossys config set ELASTICSEARCH_REST_URL "http://<admin_server>:9200" --service rest --insecure
```
Restart PLOSSYS 5:
```
plossys service start
```

Logging in a Cluster¶

Hint - each cluster member separately

All PLOSSYS 5 servers in a cluster have to transfer their log data to the same Elasticsearch server. Therefore you have to perform the following instructions on each cluster member separately.

On the PLOSSYS 5 server, edit the following file:
```
/opt/seal/etc/filebeat.yml
```
In elasticsearch, replace localhost by the host name or IP address of the management server:
```
output:
  elasticsearch:
    hosts:
    - http://<admin_server>:9200
```
Save the file.
In the seal-rest service, specify the following key:
- ELASTICSEARCH_REST_URL: URL of the Elasticsearch server
Example of setting the key via PLOSSYS CLI
```
plossys config set ELASTICSEARCH_REST_URL "http://<admin_server>:9200" --service rest --insecure
```
Restart PLOSSYS 5:
```
plossys service start
```

Displaying the Log Messages of PLOSSYS 5 in Kibana¶

The log messages of PLOSSYS 5 can be displayed and evaluated in the Kibana user interface.

Open the Kibana user interface in a Web browser:

http://<admin_server>:5601

Hint - saving search settings

Kibana does not save search settings. But as the search settings are included in the URL you can save the search settings as bookmarks.
