What is a Satellite?

?


“A satellite is a moon, planet or machine that orbits a planet or star. For example, Earth is a satellite because it orbits the sun. Likewise, the moon is a satellite because it orbits Earth. Usually, the word "satellite" refers to a machine that is launched into space and moves around Earth or another body in space.” - NASA

Why Monitor A Satellite with Nagios?

• Our support model and operational concepts changed

– Satellite Operators requested better support

– Longer mission durations changed mission operations

• Advanced Satellite Control System does not have monitoring and notification capability

• Our support model and operational concepts changed

– Satellite Operators requested better support

– Longer mission durations changed mission operations

• Advanced Satellite Control System does not have monitoring and notification capability


• You need the following

– A satellite

– Telemetry

– An application to process telemetry

– An application to monitor and notify

How to monitor a satellite


“Telemetry is the highly automated communications process by which measurements are made and other data collected at remote or inaccessible points and transmitted to receiving equipment for monitoring.” - Wikipedia

Boeing’s Advanced Satellite Controls System (ASCS) decommutates telemetry into engineering (human readable) values

Local check routineSubscribes to ASCS message busConverts the data into Nagios plugin API compatible dataSubmits a passive service check to the Nagios external command file as required

The “global” Nagios server aggregates data from the “spacecraft” Nagios instance running on the ASCS server

On-orbit fleet monitoring




• Deployed an instance of Nagios per spacecraft– Currently monitoring 17 on-orbit spacecraft and growing

• Passive service checks using the external command file– Service checks can range from 8,000 to 20,000 per spacecraft

• Check_MK Multisite used for aggregate view– Total number of services checked just over 221,000

• MK Livestatus used to access status data and by Multisite

• Operating systems: Fedora & Solaris (ASCS)

What’s Next

• 702SP

– All Electric

– Long assent duration

– Short contact windows

– Nagios event handler


Guiding Principles• “Do One Thing and Do It Well”

– Nagios and ASCS on their own each do one thing well

– Combined they create a whole new set of capabilities

• Keep it simple

• Make it modular

• Solaris+Open Source – Don’t try this at home or anywhere

• JSON everywhere
