From 97fc96d8f8b5ac83ade0af269ccb98cb1a2abdf0 Mon Sep 17 00:00:00 2001 From: Sebastian Harl Date: Thu, 20 Nov 2014 23:19:18 +0100 Subject: [PATCH 1/1] Initial commit of the SysDB web interface. This is the initial version of a web-based client programm for querying SysDB (https://sysdb.io/). For now, it supports browsing, querying, and displaying basic information about hosts, services, and metrics. --- COPYING | 24 +++ README | 99 +++++++++++++ main.go | 81 +++++++++++ server/error.go | 71 +++++++++ server/server.go | 299 ++++++++++++++++++++++++++++++++++++++ static/images/favicon.png | Bin 0 -> 891 bytes static/images/owl.png | Bin 0 -> 6187 bytes static/style/main.css | 160 ++++++++++++++++++++ templates/host.tmpl | 33 +++++ templates/hosts.tmpl | 14 ++ templates/main.tmpl | 48 ++++++ templates/metric.tmpl | 18 +++ templates/metrics.tmpl | 18 +++ templates/service.tmpl | 18 +++ templates/services.tmpl | 18 +++ 15 files changed, 901 insertions(+) create mode 100644 COPYING create mode 100644 README create mode 100644 main.go create mode 100644 server/error.go create mode 100644 server/server.go create mode 100644 static/images/favicon.png create mode 100644 static/images/owl.png create mode 100644 static/style/main.css create mode 100644 templates/host.tmpl create mode 100644 templates/hosts.tmpl create mode 100644 templates/main.tmpl create mode 100644 templates/metric.tmpl create mode 100644 templates/metrics.tmpl create mode 100644 templates/service.tmpl create mode 100644 templates/services.tmpl diff --git a/COPYING b/COPYING new file mode 100644 index 0000000..b7a1f1b --- /dev/null +++ b/COPYING @@ -0,0 +1,24 @@ +Copyright (c) 2014 Sebastian 'tokkee' Harl +All rights reserved. + +Redistribution and use in source and binary forms, with or without +modification, are permitted provided that the following conditions +are met: +1.

It stores system and inventory information about + hardware and software systems. This information is (continuously) collected + from various configurable backends (inventory services, monitoring services, + etc.) and stored in a graph-like hierarchy of generic objects. The store may + be queried through a generic interface independent of the active backends. + Object names are canonicalized before they are added to the store to ensure + a consistent view of your infrastructure. + + The central object type is a host, which generally represents a physical or + virtual machine or any other type of physical resource. Hosts, in turn, may + reference a list of services which represent any kind of logical resource + like a software system. Both, hosts and services, may reference a list of + attributes which represent further information about the respective host or + service object. For example, attributes may specify static information like + a host's architecture or the software version. A host may also reference a + list of metrics which are references to performance data stored about the + host. SysDB supports querying the respective time-series from a backend's + data store. + + SysDB is free and open source software, licensed under the 2-clause BSD + license. See COPYING for details. + + + +Install the web-interface +------------------------- + + The SysDB webui is written in Go. It can be installed along with all of its + dependencies as easy as running the following command: + + go get github.com/sysdb/webui/... + + This will download and install the packages and all of their dependencies + into GOPATH. See ‘go help get’ for more details. + +Running the web-interface +------------------------- + + The SysDB webui is a standalone web application. It can run all on its own + but it can also be put behind a reverse proxy (e.g. using Apache or nginx). + It is composed of a dynamic application and a set of static files (images + and style-sheets) which are shipped along with the source distribution. You + can start the application using the following command, using the --address + option to point it at a running SysDB daemon: + + ./webui \ + --address=/var/run/sysdbd.sock \ + --listen=:8080 \ + --static-path=$GOPATH/src/github.com/sysdb/webui/static \ + --template-path=$GOPATH/src/github.com/sysdb/webui/templates + + You can then access the interface by pointing your browser at + http://localhost:8080 + +Packages +-------- + + While the webui is a standalone application, most of its functionality is + implemented in a reusable library allowing to integrate it into other + software written in Go. + + * github.com/sysdb/webui/server: The core of the SysDB web server. + + It makes use of the following packages: + + * github.com/sysdb/go/client (and related packages): A SysDB client + implementation. + +Documentation +------------- + + The documentation for all Go packages is included with the source code in a + way compatible with the godoc tool. As such, it can be viewed and browsed + online at . + +Getting Help +------------ + + Various channels for asynchronous and real-time communication with + developers and users are available. See for + details about the mailing list, IRC channel, and social media. + +Author +------ + + Sebastian “tokkee” Harl + + Want to contribute?
