LibreNMS

This guide configures LibreNMS to stream metrics to Layer 9 via the InfluxDB protocol.

Prerequisites

• A running LibreNMS instance
• Administrator access to LibreNMS
• Outbound internet access to the metrics endpoint
  • Firewall allows egress to TCP 443
  • Router/NAT supports outgoing HTTPS

Step 1: Coordinate with Layer 9 Team

Contact the Layer 9 team to obtain your organization-specific connection details:

• Metrics endpoint (e.g., <name>.librenms.layer9.com)
• Secret key

Step 2: Configure InfluxDBv2 Datastore

Navigate to Global Settings > Poller > Datastore in the LibreNMS web interface.

Locate the InfluxDBv2 section and configure the following settings:

Setting	Value
Transport	https
Host	Your metrics endpoint
Port	443
Token	Your secret key
Bucket	librenms
Organization	librenms

Toggle Enable to activate the datastore.

Alternatively, add to your config.php:

$config['influxdbv2']['enable'] = true;
$config['influxdbv2']['transport'] = 'https';
$config['influxdbv2']['host'] = '<METRICS ENDPOINT>';
$config['influxdbv2']['port'] = 443;
$config['influxdbv2']['token'] = '<SECRET KEY>';
$config['influxdbv2']['bucket'] = 'librenms';
$config['influxdbv2']['organization'] = 'librenms';
