Syslog Integration Requirements

Confirm that your Syslog server meets the following requirements:

Network protocol

The syslog server should be able to receive data via one of the following protocols:

  • TCP - for unencrypted connections.
  • TLS - for encrypted connections. Validation of the Certificate Authority (CA) and mutual TLS are currently not supported.

Syslog Format

  • The forwarder produces RFC-5424-compliant messages.

  • For delimiting, the octet count is added to every syslog message. See RFC-5425 for details.

Example of a message sent by the forwarder in syslog format:

<6>1 2019-09-10T06:40:15+02:00 controller.fqdn.svc nginx_controller 1 ngxctrl [dimensions alias="my_system" category="agent event" counter="1" instance="" instance.tags="tag1,tag2" level="INFO" local_id="d23c85484ee760ee5f4619c0434e1968b5290964487541da0889964eb783613c" location="" message="nginx stub_status detected, https://127.0.0.1:443/basic_status" parent_hostname="d0784771a503" root_uuid="49946669ca315d45bae1d6c05de9bd7e"] nginx stub_status detected, https://127.0.0.1:443/basic_status

Example configuration for Syslog-NG

The example of syslog-ng.conf that receives messages over TLS:

@version: 3.29
@include "scl.conf"

source s_network {
    default-network-drivers(
    tls(key-file("/key.pem") cert-file("/cert.pem") peer-verify(optional-trusted))

    # the optional flag that enables the access to $RAWSMSG
    flags(store-raw-message)
    );
};

destination d_remote  {
    file("/var/log/controller.events.log");

    # if you want to see the raw message with all dimensions:
    file("/var/log/controller.events.raw.log" template("${RAWMSG}\n"));
};

log {
    source(s_network);
    destination(d_remote);
};

Add a Syslog Integration

Take the following steps to create an Integration for syslog:

  1. Open the F5 NGINX Controller user interface and log in.
  2. Select the NGINX Controller menu icon, then select Platform.
  3. On the Platform menu, select Integrations.
  4. On the Integrations menu, select the Create Integration quick action.
  5. Add a name.
  6. (Optional) Add a display name.
  7. (Optional) Add a description.
  8. (Optional) Add tags.
  9. In the Integration Type list, select GENERIC_INTEGRATION.
  10. In the Endpoint URI box, add the TCP endpoint for your syslog. Syslog's URL can be provided in two formats:
    • tcp://hostname[:port] for unencrypted TCP connections (example: tcp://192.168.0.1:601).
    • tcp+tls://hostname[:port] for encrypted TCP connections with TLS (example: tcp+tls://192.168.0.1:6514)
  11. In the Credential Type list, select UNAUTHENTICATED.
  12. Select Submit.
