Developer Notes
---------------

Collected here are some topics that may interest the megatest developer.

telemetry
~~~~~~~~~

A new feature introduced in v1.6525 allows a centralized debug messaging system.  Debugging client-server issues
is greatly aided by a centralized, time coherent log of events across test execution, server, and runner.  This
is provided by the telemetry feature


source code call example


[source,ini]
 [telemetry]
 host <IP where telemetry daemon will run>
 port <UDP port to listen -- we recommend 5929>
 want-events <comma separated list of telemetry-log keywords

[source,ini]
 [telemetry]
 host 10.38.32.91
 port 5929
 want-events ALL

[source,scheme]
(common:telemetry-log <keyword string>


Usage:
1. Add telemetry section to megatest.config
2. Start telemetry daemon telemetry-daemon -a start -l /tmp/my-telemetry.log
3. Run megatest
4. examine / parse telemetry log

which can launch jobs on local and remote Linux hosts. Currently
megatest uses the network filesystem to call home to your master
sqlite3 database. Megatest has been used with the Intel Netbatch and
lsf (also known as openlava) batch systems and it should be
straightforward to use it with other similar systems.</p></div>

<div class="paragraph"><p>Megatest is designed as a distributed or decoupled system. This means
you can run the areas stand-alone with no additional

Multi-area dashboard and xterm. A gui (the dashboard) is usually the
  best option for controlling and launching runs but all operations
  can also be done from the commandline. Note: The not yet released
  multi-area dashboard replaces the old dashboard for browsing and
  controlling runs but for managing a single area the old dashboard
  works very well.

<p>
Area/testsuite. This is your testsuite or automation definition and
  consists of the information in megatest.config, runconfigs.config
  and your testconfigs along with any custom scripting that can&#8217;t be
  done with the native Megatest features.
</p>
</li>
<li>
<p>
If your testsuite or build automation is too large to run on a
  single instance you can distribute your jobs into a compute server
  pool. The only current requirements are password-less ssh access and
  a network filesystem.
