Metrics

Introduction​

The metrics provides the time sensitive data about the system cpu(s), memory and port(s) at regular interval.

Sample rate​

The sample rate in seconds determines the interval at which the metrics is collected and updated. The default sample rate is 20 seconds

CPU​

The system provides the current cpu utilization (load) for each cpu core and summary of utilisation in total.

Memory​

The system provides the following memory metrics

  • Memory Metrics:
    • Total Memory (kB)
    • Used Memory (kB) and in percentage of total memory
    • Free Memory (kB) and in percentage of total memory
    • Available Memory (kB) and in percentage of total memory

Ports​

The system provides the following memory metrics

  • Port Metrics:
    • Speed (Mbit/s) and duplex full or half
    • Inbound bitrate per second
    • Outbound bitrate per second
    • Utilisation

Port-utilisation​

By default the port metrics are not enabled and it needs to be enabled to collect and present port metrics

Web​

The metrics can be viewed in open metrics format by enabling the web option. The default port is 9100. It is possible to configure ports between 1024 and 65535.

warning

Metrics data available on the Web works only if https is enabled in the management

SNMP​

Enables metrics data to be available via SNMP request
