Filebeat, a part of the ELK stack, is a lightweight shipper for forwarding and centralizing log data. This article introduces the best practices that Talend suggests you follow when working with Filebeat.
Click the following links for the recommended configuration when using Filebeat with the following Talend components:
Note: that all components are separate and can be installed on different machines.
The article shows you how to configure and redirect all logs to the centralized logging solution, Log Server.
The Log Server installation provides the following components:
These components are already integrated and don’t require a deep configuration.
Usually, in the DEV/TEST environment, Log Server is installed on the same machine as the other Talend components (TAC, Runtime, and others). Thus, the configuration related to remote connections is not necessary.
However, in the PREPROD or PROD environments, Talend recommends installing Log Server on dedicated machines and clustered.
The configuration covered in this article is only for a single node installation (not a cluster). In Production, Talend recommends a cluster solution, and depending on the load Elasticsearch, Logstash, and Kibana; it can be installed on a dedicated machine.
Firewall configuration is necessary to permit remote communication to Log Server. Thus, it’s necessary to open the following ports:
By default, Elasticsearch only accepts a local connection. Edit the configuration to permit Elasticsearch to receive a remote connection using port 9200:
Edit the %LogServer_installation%/logserv/elasticsearch-6.1.2/config/elasticsearch.yml file.
Change network.host to accept the remote connection:
network.host: ip_address - binding to accept a remote connection to specific IPs
network.host: 0.0.0.0 - binding to accept all remote connections
Optional: To avoid the bootstrap check (only for single node), add the following parameter:
If Log Server is installed on a different machine respective of TAC, it is necessary to set the Kibana URL in TAC.
Connect to TAC.
Navigate to Configuration > Monitoring, and configure the Kibana URL by replacing the localhost with the Log Server IP address. This configuration permits Log Server to see the Kibana portal from the TAC portal under Monitoring > Logging.
