elos

elos is a tool to collect, store and publish various system events (i.e. syslogs, core dumps, measurements obtained from proc- and sys-fs, …) while providing easy access to the collected data.

elos and its libraries:

• elos
• safu
• samconf

and for testing:

• cmocka_mocks
• cmocka_extensions

Quick start

Try elos

./elos/ci/docker-target-run.sh
...
ci@2153762153:/$ elosc -f "1 1 EQ"
...
ci@2153762153:/$ elosc -s "1 1 EQ"

On a second shell attach to the running container

docker exec -ti <elos_container_name> bash
ci@2153762153:/$ elosc -p '{"payload": "Hello elos"}'

For detailed build instructions have a look into ./elos/ci/docker-target-run.sh and/or consult the documentation https://elektrobit.github.io/elos .

Development

For a quick start to get hands on the code and start coding use :

./elos/ci/docker-run.sh

You are now in a ready to use development environment. To build elos and all dependencies run:

ci@62209400:/base$ ./elos/ci/build.sh

To start elosd and play with your changes:

ci@62209400:/base$ ./elos/test/smoketest/smoketest_interactive.sh
[elos-interactive]$ elosd&
...
[elos-interactive]$ elosc -f "1 1 EQ"
...
[elos-interactive]$ elosc -s "1 1 EQ"&
...
[elos-interactive]$ elosc -p '{"payload": "Hello elos"}'
...
[elos-interactive]$ elosc # be creative

Be aware this is a smoketest environment so it is very verbose.
