Topic First Debian Conference
Subtopic Telemetry Box
Christoph Lameter
Telemetry: The science and technology of automatic measurement and
transmission of data by wire, radio, or other means from remote
sources, as from space vehicles, to a receiving station for recording
and analysis. The American Heritage Dictionary, Second College
Edition
The Telemetry Box is a information gathering device. Telemetry is
often associated with data retrieval from space vehicles (such as the
Galileo or the Voyager probes) over long distances. Like Space Probes
a Telemetry Box comes equipped with "sensors" (called monitors) that
allow it to probe the environment and a data storage device to record
the results. It also has a processing facility in order to process
and/or reduce the data to be transmitted. Space Probes like Galileo
have multiple means of communication like for example a low-gain (not
directional) and a high-gain (directional highly focused) antenna and
transmitter. Like a space probe a telemetry box has multiple means of
communication and relaying of the data collected.
In our context the Telemetry Box is used to monitor and collect
data about devices operating in a networked environment. Telemetry Box
data allows among other things diagnostics on web-servers, networks
and of connectivity. The Telemetry-Box can verify that certain
functionality exist and generate alerts if the testing of that
functionality fails. The Telemetry box tries to behave like a nice
observer trying to avoid interference with the system to be monitored
as much as possible and is designed around a goal of striving of
agent less monitoring.
A Telemetry box is a self-contained device and can be placed
anywhere on the networks. For certain types of diagnostics the
location is key to the ability to retrieve special
information. Location is also critical in order for the Telemetry box
to create minimal load and reduce its intrusiveness into the
environment to be monitored. The telemetry box has a means of
encrypted communication (analogous to a highly directional beam of a
high gain antenna) as well as the ability to communicate via standard
protocols such as http (which is easily accessible from anywhere but
insecure).
The presentation in Bordeaux will cover:
- Introduction to the Telemetry Box ideas.
- Demonstration of simplified installation procedure
for Debian/Linux from Credit Card CD
- Demonstration of diagnostics features
- MON
- Netsaint
- WebRFM remote management
- Plain old commandline tools
- (Use of postgres as a data warehouse for diagnostic information)
