-Another way to collect and monitor BPQ's SNMP metrics is by using Telegraf. You typically run Telegraf as part of a monitoring stack, in this case Telegraf + InfluxDB + Grafana.

+===== Prometheus =====
+It's also quite easy to get prometheus-snmp-exporter to collect stats from BPQ.
+Add something like the following to your generator.yml
+<code>
+  linbpq:
+    walk:
+      - 1.3.6.1.2.1.1.3.0
+      - 1.3.6.1.2.1.1.5
+      - 1.3.6.1.2.1.2.2.1.10.1
+      - 1.3.6.1.2.1.2.2.1.16.1
+    version: 1
+    auth:
+      community: public
+</code>
+Repeat the 1.3.6.1.2.1.2.2.1.10.X and 1.3.6.1.2.1.2.2.1.16.X lines for each of your ports, then run prometheus-snmp-generator generate to regenerate your configuration.
+You'll likely already have an snmp scrape configuration in your prometheus.yml.
+Add the linbpq module (as defined above) and the target address of your BPQ node to it.
+The result will look something like this:
+<code>
+  - job_name: 'snmp'
+    scrape_interval: 20s
+    scrape_timeout: 5s
+    metrics_path: /snmp
+    params:
+      module: [linbpq]
+    static_configs:
+      - targets:
+        - packet.example.org:8161  # SNMP device - add your IPs here
+    relabel_configs:
+      - source_labels: [__address__]
+        target_label: __param_target
+      - source_labels: [__param_target]
+        target_label: instance
+      - target_label: __address__
+        replacement: 127.0.0.1:9116  # SNMP exporter.
+</code>
+After restarting prometheus-snmp-exporter and prometheus you should start seeing ifInOctets, ifOutOctets, sysName, and sysUpTime metrics appearing.
