# JCHAOS This javascript module can be used, both in HTML or as nodejs library to access !CHAOS resources. This package bundles some !CHAOS utility and management applications. ## Install Global installation: **npm** install -g jchaos NPM Will install library and applications ## Repository [git@baltig.infn.it:chaos-lnf-control/jchaos.git](git@baltig.infn.it:chaos-lnf-control/jchaos.git) ## Application ### jchaosctl This application will perform management operation on chaos. The basic usage is: ``` bash /usr/bin/jchaosctl <--server server:port> [--upload ] [--download >] [--findlive < cu | us | agent | mds | webui | variable | snapshotsof | snapshots | script | zone | class >] [--find < cu | us | agent | mds | webui | variable | snapshotsof | snapshots | script | zone | class >] [--op < start | stop | init | deinit| load | unload | kill | shutdown |health>] [--uid ] [--help] ``` ### jchaos library ### Table of Contents -
