Accessing historical telemetry

Goal

In this tutorial you will:

  • Power on DPU board to generate several minutes of telemetry data

  • Access historical telemetry data from Smart Mission Lab system

Prerequisites

  • Active subscription within Smart Mission Lab system

  • Active VPN connection to Smart Mission Lab system

  • Access to EGSE Host

  • Board prepared to run Linux distribution

    • For Antelope use Linux distribution built in Zero to hero tutorials

A bit of background

When board’s supervisor is running, Smart Mission Lab system continuously monitors telemetry readouts from board. Customer can access collected values using Grafana web application.

Generate telemetry data

  1. Log in to EGSE Host using SSH

    user@my-machine:~$ ssh customer@egse-my-egse.egse.sml.lan
customer@egse-my-egse:~$

  2. Power on board

    customer@egse-my-egse:~$ sml power on
Powering on...Success

    customer@egse-my-egse:~$ sml power on
Powering on...Success

  3. Wait 2 minutes

  4. Power on DPU

    customer@egse-my-egse:~$ sml dpu power on
Powering on...Success
customer@egse-my-egse:~$ sml dpu reset off
Bringing DPU out of reset...Success

    customer@egse-my-egse:~$ sml pn1 power on
Powering on...Success

Access historical telemetry

  1. Open https://grafana.vpn.sml.kplabs.space in your web browser

  2. Grafana will redirected you to Customer Dashboard for sign-in. Log-in using your credentials

  3. After successful login, you will go back to Grafana home page automatically

  4. Open dashboard with telemetry for your board (for Antelope use Antelope Telemetry, for Leopard use Leopard Telemetry)

  5. Select board to display telemetry by selecting name of your EGSE Host in hostname dropdown at the top of the dashboard

  6. Select time range that contains this tutorial by selecting Last 30 minutes

    ../_images/grafana_time_range.png

    Fig. 17 Select time range to display

    Note

    If you performed first part of this tutorial (powering on board) more than 30 minutes ago, you can select different time range. Use longer ‘last ..’ selection or enter absolute times to show data gathered during this tutorial.

  7. Dashboard now displays telemetry data from your board.

Summary

SML infrastructure constantly monitors and collects telemetry readouts from boards. At any point in time, you can use Grafana to review collected data.
