This is sh-based DWARFG_LONG agent for universal GNU/Linux device.

Maturity status: basic functionality + systemd/initd integration.

Installation:

1) as root, run ./DWARFG_SHORT_agent.sh
2) if previous installation of the agent is found (/opt/aDWARFG_SHORT), installation will fail as you need to remove the previous version first (see Uninstallation below).
3) agent is deployed in /opt/aDWARFG_SHORT, systemd/initd integration is attempted if systemd/initd is detected.
4) Agent is started afterwards

Uninstallation:

1) as root, run /opt/aDWARFG_SHORT/uninstall.sh

Notes:

You can found some information and log files inside /opt/aDWARFG_SHORT directory. Please note that messing with any of the files content may render the agent non-functional.

List of some of the files created upon deployment:

/opt/aDWARFG_SHORT/server.ini ... contains server URL (if not present, default address from script is used)
/opt/aDWARFG_SHORT/server.pem ... contains server pem certificate if server uses certificates that cannot be authenticated by using public authorities (e.g. self-signed certificate)
/opt/aDWARFG_SHORT/settings.ini ... contains all other settings. Refer below.
/opt/aDWARFG_SHORT/global_log.txt ... contains global log of the agent
/opt/aDWARFG_SHORT/uninstall.sh ... contains uninstall script (customized upon deployment)
/opt/aDWARFG_SHORT/<PID> ... working directory for agent with PID <PID>, most importantly containing its log (the non-global messages)

Selected keys from settings.ini:

DEVICE_ID ... ID of the device in DWARFG_LONG server it is registered with

Selected keys from settings.ini that you can mess with (though no one guarantees anything if you do it):

[DLS]LEVEL ... numeric settings determining which loglevel is ok to go to debug, log or syslog. loglevel 1 is pure debug, 6 is fatal
INTERVAL_* ... number of seconds between data pushes. Warning: shortening this too much will not only increase server load, but could cause errors with data processing. The recommended minimum is 120 seconds. The tested minimum with local DWARFG_LONG server is 4 seconds (NOT RECOMMENDED!). The default is 260 and it is strongly recommended to stick with that.
SMALLCYCLES ... number of regular cycles until bigcycle is executed
SECURITY ... 2, 1 or 0. 2 is the default, 1 allows for semi-secure way of server certificate update, 0 disables server certificate checking. Note that even with 0, HTTPS protocol is used.
