+Seelog
+=======
+
+Seelog is a powerful and easy-to-learn logging framework that provides functionality for flexible dispatching, filtering, and formatting log messages.
+It is natively written in the [Go](http://golang.org/) programming language. 
+
+[![Build Status](https://drone.io/github.com/cihub/seelog/status.png)](https://drone.io/github.com/cihub/seelog/latest)
+
+Features
+------------------
+
+* Xml configuring to be able to change logger parameters without recompilation
+* Changing configurations on the fly without app restart
+* Possibility to set different log configurations for different project files and functions
+* Adjustable message formatting
+* Simultaneous log output to multiple streams
+* Choosing logger priority strategy to minimize performance hit
+* Different output writers
+  * Console writer
+  * File writer 
+  * Buffered writer (Chunk writer)
+  * Rolling log writer (Logging with rotation)
+  * SMTP writer
+  * Others... (See [Wiki](https://github.com/cihub/seelog/wiki))
+* Log message wrappers (JSON, XML, etc.)
+* Global variables and functions for easy usage in standalone apps
+* Functions for flexible usage in libraries
+
+Quick-start
+-----------
+
+```go
+package main
+
+import log "github.com/cihub/seelog"
+
+func main() {
+    defer log.Flush()
+    log.Info("Hello from Seelog!")
+}
+```
+
+Installation
+------------
+
+If you don't have the Go development environment installed, visit the 
+[Getting Started](http://golang.org/doc/install.html) document and follow the instructions. Once you're ready, execute the following command:
+
+```
+go get -u github.com/cihub/seelog
+```

+Package seelog implements logging functionality with flexible dispatching, filtering, and formatting.
+
+Creation
+
+To create a logger, use one of the following constructors:
+  func LoggerFromConfigAsBytes
+  func LoggerFromConfigAsFile
+  func LoggerFromConfigAsString
+  func LoggerFromWriterWithMinLevel
+  func LoggerFromWriterWithMinLevelAndFormat
+  func LoggerFromCustomReceiver (check https://github.com/cihub/seelog/wiki/Custom-receivers)
+Example:
+  import log "github.com/cihub/seelog"
+
+  func main() {
+      logger, err := log.LoggerFromConfigAsFile("seelog.xml")
+      if err != nil {
+          panic(err)
+      }
+      defer logger.Flush()
+      ... use logger ...
+  }
+The "defer" line is important because if you are using asynchronous logger behavior, without this line you may end up losing some
+messages when you close your application because they are processed in another non-blocking goroutine. To avoid that you
+explicitly defer flushing all messages before closing.
+
+Usage
+
+Logger created using one of the LoggerFrom* funcs can be used directly by calling one of the main log funcs.
+Example:
+  import log "github.com/cihub/seelog"
+
+  func main() {
+      logger, err := log.LoggerFromConfigAsFile("seelog.xml")
+      if err != nil {
+          panic(err)
+      }
+      defer logger.Flush()
+      logger.Trace("test")
+      logger.Debugf("var = %s", "abc")
+  }
+
+Having loggers as variables is convenient if you are writing your own package with internal logging or if you have
+several loggers with different options.
+But for most standalone apps it is more convenient to use package level funcs and vars. There is a package level
+var 'Current' made for it. You can replace it with another logger using 'ReplaceLogger' and then use package level funcs:
+  import log "github.com/cihub/seelog"
+
+  func main() {
+      logger, err := log.LoggerFromConfigAsFile("seelog.xml")
+      if err != nil {
+          panic(err)
+      }
+      log.ReplaceLogger(logger)
+      defer log.Flush()
+      log.Trace("test")
+      log.Debugf("var = %s", "abc")
+  }
+Last lines
+      log.Trace("test")
+      log.Debugf("var = %s", "abc")
+do the same as
+      log.Current.Trace("test")
+      log.Current.Debugf("var = %s", "abc")
+In this example the 'Current' logger was replaced using a 'ReplaceLogger' call and became equal to 'logger' variable created from config.
+This way you are able to use package level funcs instead of passing the logger variable.
+
+Configuration
+
+Main seelog point is to configure logger via config files and not the code.
+The configuration is read by LoggerFrom* funcs. These funcs read xml configuration from different sources and try
+to create a logger using it.
+
+All the configuration features are covered in detail in the official wiki: https://github.com/cihub/seelog/wiki.
+There are many sections covering different aspects of seelog, but the most important for understanding configs are:
+    https://github.com/cihub/seelog/wiki/Constraints-and-exceptions
+    https://github.com/cihub/seelog/wiki/Dispatchers-and-receivers
+    https://github.com/cihub/seelog/wiki/Formatting
+    https://github.com/cihub/seelog/wiki/Logger-types
+After you understand these concepts, check the 'Reference' section on the main wiki page to get the up-to-date
+list of dispatchers, receivers, formats, and logger types.
+
+Here is an example config with all these features:
+    <seelog type="adaptive" mininterval="2000000" maxinterval="100000000" critmsgcount="500" minlevel="debug">
+        <exceptions>
+            <exception filepattern="test*" minlevel="error"/>
+        </exceptions>
+        <outputs formatid="all">
+            <file path="all.log"/>
+            <filter levels="info">
+              <console formatid="fmtinfo"/>
+            </filter>
+            <filter levels="error,critical" formatid="fmterror">
+              <console/>
+              <file path="errors.log"/>
+            </filter>
+        </outputs>
+        <formats>
+            <format id="fmtinfo" format="[%Level] [%Time] %Msg%n"/>
+            <format id="fmterror" format="[%LEVEL] [%Time] [%FuncShort @ %File.%Line] %Msg%n"/>
+            <format id="all" format="[%Level] [%Time] [@ %File.%Line] %Msg%n"/>
+            <format id="criticalemail" format="Critical error on our server!\n    %Time %Date %RelFile %Func %Msg \nSent by Seelog"/>
+        </formats>
+    </seelog>
+This config represents a logger with adaptive timeout between log messages (check logger types reference) which
+logs to console, all.log, and errors.log depending on the log level. Its output formats also depend on log level. This logger will only
+use log level 'debug' and higher (minlevel is set) for all files with names that don't start with 'test'. For files starting with 'test'
+this logger prohibits all levels below 'error'.
+
+Configuration using code
+
+Although configuration using code is not recommended, it is sometimes needed and it is possible to do with seelog. Basically, what
+you need to do to get started is to create constraints, exceptions and a dispatcher tree (same as with config). Most of the New*
+functions in this package are used to provide such capabilities.
+
+Here is an example of configuration in code, that demonstrates an async loop logger that logs to a simple split dispatcher with
+a console receiver using a specified format and is filtered using a top-level min-max constraints and one expection for
+the 'main.go' file. So, this is basically a demonstration of configuration of most of the features:
+
+  package main
+
+  import log "github.com/cihub/seelog"
+
+  func main() {
+      defer log.Flush()
+      log.Info("Hello from Seelog!")
+
+      consoleWriter, _ := log.NewConsoleWriter()
+      formatter, _ := log.NewFormatter("%Level %Msg %File%n")
+      root, _ := log.NewSplitDispatcher(formatter, []interface{}{consoleWriter})
+      constraints, _ := log.NewMinMaxConstraints(log.TraceLvl, log.CriticalLvl)
+      specificConstraints, _ := log.NewListConstraints([]log.LogLevel{log.InfoLvl, log.ErrorLvl})
+      ex, _ := log.NewLogLevelException("*", "*main.go", specificConstraints)
+      exceptions := []*log.LogLevelException{ex}
+
+      logger := log.NewAsyncLoopLogger(log.NewLoggerConfig(constraints, exceptions, root))
+      log.ReplaceLogger(logger)
+
+      log.Trace("This should not be seen")
+      log.Debug("This should not be seen")
+      log.Info("Test")
+      log.Error("Test2")
+  }
+
+Examples
+
+To learn seelog features faster you should check the examples package: https://github.com/cihub/seelog-examples
+It contains many example configs and usecases.

+Why GoReq?
+==========
+
+Go has very nice native libraries that allows you to do lots of cool things. But sometimes those libraries are too low level, which means that to do a simple thing, like an HTTP Request, it takes some time. And if you want to do something as simple as adding a timeout to a request, you will end up writing several lines of code.
+
+This is why we think GoReq is useful. Because you can do all your HTTP requests in a very simple and comprehensive way, while enabling you to do more advanced stuff by giving you access to the native API.
+
+How do I install it?
+====================
+
+```bash
+go get github.com/franela/goreq
+```
+
+What can I do with it?
+======================
+
+## Making requests with different methods
+
+#### GET
+```go
+res, err := goreq.Request{ Uri: "http://www.google.com" }.Do()
+```
+
+GoReq default method is GET.
+
+You can also set value to GET method easily
+
+```go
+type Item struct {
+        Limit int
+        Skip int
+        Fields string
+}
+
+item := Item {
+        Limit: 3,
+        Skip: 5,
+        Fields: "Value",
+}
+
+res, err := goreq.Request{
+        Uri: "http://localhost:3000/",
+        QueryString: item,
+}.Do()
+```
+The sample above will send `http://localhost:3000/?limit=3&skip=5&fields=Value`
+
+Alternatively the `url` tag can be used in struct fields to customize encoding properties
+
+```go
+type Item struct {
+        TheLimit int `url:"the_limit"`
+        TheSkip string `url:"the_skip,omitempty"`
+        TheFields string `url:"-"`
+}
+
+item := Item {
+        TheLimit: 3,
+        TheSkip: "",
+        TheFields: "Value",
+}
+
+res, err := goreq.Request{
+        Uri: "http://localhost:3000/",
+        QueryString: item,
+}.Do()
+```
+The sample above will send `http://localhost:3000/?the_limit=3`
+
+
+QueryString also support url.Values
+
+```go
+item := url.Values{}
+item.Set("Limit", 3)
+item.Add("Field", "somefield")
+item.Add("Field", "someotherfield")
+
+res, err := goreq.Request{
+        Uri: "http://localhost:3000/",
+        QueryString: item,
+}.Do()
+```
+
+The sample above will send `http://localhost:3000/?limit=3&field=somefield&field=someotherfield`
+
+### Tags
+
+Struct field `url` tag is mainly used as the request parameter name.
+Tags can be comma separated multiple values, 1st value is for naming and rest has special meanings.
+
+- special tag for 1st value
+    - `-`: value is ignored if set this
+
+- special tag for rest 2nd value
+    - `omitempty`: zero-value is ignored if set this
+    - `squash`: the fields of embedded struct is used for parameter
+
+#### Tag Examples
+
+```go
+type Place struct {
+    Country string `url:"country"`
+    City    string `url:"city"`
+    ZipCode string `url:"zipcode,omitempty"`
+}
+
+type Person struct {
+    Place `url:",squash"`
+
+    FirstName string `url:"first_name"`
+    LastName  string `url:"last_name"`
+    Age       string `url:"age,omitempty"`
+    Password  string `url:"-"`
+}
+
+johnbull := Person{
+	Place: Place{ // squash the embedded struct value
+		Country: "UK",
+		City:    "London",
+		ZipCode: "SW1",
+	},
+	FirstName: "John",
+	LastName:  "Doe",
+	Age:       "35",
+	Password:  "my-secret", // ignored for parameter
+}
+
+goreq.Request{
+	Uri:         "http://localhost/",
+	QueryString: johnbull,
+}.Do()
+// =>  `http://localhost/?first_name=John&last_name=Doe&age=35&country=UK&city=London&zip_code=SW1`
+
+
+// age and zipcode will be ignored because of `omitempty`
+// but firstname isn't.
+samurai := Person{
+	Place: Place{ // squash the embedded struct value
+		Country: "Japan",
+		City:    "Tokyo",
+	},
+	LastName: "Yagyu",
+}
+
+goreq.Request{
+	Uri:         "http://localhost/",
+	QueryString: samurai,
+}.Do()
+// =>  `http://localhost/?first_name=&last_name=yagyu&country=Japan&city=Tokyo`
+```
+
+
+#### POST
+
+```go
+res, err := goreq.Request{ Method: "POST", Uri: "http://www.google.com" }.Do()
+```
+
+## Sending payloads in the Body
+
+You can send ```string```, ```Reader``` or ```interface{}``` in the body. The first two will be sent as text. The last one will be marshalled to JSON, if possible.
+
+```go
+type Item struct {
+    Id int
+    Name string
+}
+
+item := Item{ Id: 1111, Name: "foobar" }
+
+res, err := goreq.Request{
+    Method: "POST",
+    Uri: "http://www.google.com",
+    Body: item,
+}.Do()
+```
+
+## Specifiying request headers
+
+We think that most of the times the request headers that you use are: ```Host```, ```Content-Type```, ```Accept``` and ```User-Agent```. This is why we decided to make it very easy to set these headers.
+
+```go
+res, err := goreq.Request{
+    Uri: "http://www.google.com",
+    Host: "foobar.com",
+    Accept: "application/json",
+    ContentType: "application/json",
+    UserAgent: "goreq",
+}.Do()
+```
+
+But sometimes you need to set other headers. You can still do it.
+
+```go
+req := goreq.Request{ Uri: "http://www.google.com" }
+
+req.AddHeader("X-Custom", "somevalue")
+
+req.Do()
+```
+
+Alternatively you can use the `WithHeader` function to keep the syntax short
+
+```go
+res, err = goreq.Request{ Uri: "http://www.google.com" }.WithHeader("X-Custom", "somevalue").Do()
+```
+
+## Cookie support
+
+Cookies can be either set at the request level by sending a [CookieJar](http://golang.org/pkg/net/http/cookiejar/) in the `CookieJar` request field
+or you can use goreq's one-liner WithCookie method as shown below
+
+```go
+res, err := goreq.Request{
+    Uri: "http://www.google.com",
+}.
+WithCookie(&http.Cookie{Name: "c1", Value: "v1"}).
+Do()
+```
+
+## Setting timeouts
+
+GoReq supports 2 kind of timeouts. A general connection timeout and a request specific one. By default the connection timeout is of 1 second. There is no default for request timeout, which means it will wait forever.
+
+You can change the connection timeout doing:
+
+```go
+goreq.SetConnectTimeout(100 * time.Millisecond)
+```
+
+And specify the request timeout doing:
+
+```go
+res, err := goreq.Request{
+    Uri: "http://www.google.com",
+    Timeout: 500 * time.Millisecond,
+}.Do()
+```
+
+## Using the Response and Error
+
+GoReq will always return 2 values: a ```Response``` and an ```Error```.
+If ```Error``` is not ```nil``` it means that an error happened while doing the request and you shouldn't use the ```Response``` in any way.
+You can check what happened by getting the error message:
+
+```go
+fmt.Println(err.Error())
+```
+And to make it easy to know if it was a timeout error, you can ask the error or return it:
+
+```go
+if serr, ok := err.(*goreq.Error); ok {
+    if serr.Timeout() {
+        ...
+    }
+}
+return err
+```
+
+If you don't get an error, you can safely use the ```Response```.
+
+```go
+res.Uri // return final URL location of the response (fulfilled after redirect was made)
+res.StatusCode // return the status code of the response
+res.Body // gives you access to the body
+res.Body.ToString() // will return the body as a string
+res.Header.Get("Content-Type") // gives you access to all the response headers
+```
+Remember that you should **always** close `res.Body` if it's not `nil`
+
+## Receiving JSON
+
+GoReq will help you to receive and unmarshal JSON.
+
+```go
+type Item struct {
+    Id int
+    Name string
+}
+
+var item Item
+
+res.Body.FromJsonTo(&item)
+```
+
+## Sending/Receiving Compressed Payloads
+GoReq supports gzip, deflate and zlib compression of requests' body and transparent decompression of responses provided they have a correct `Content-Encoding` header.
+
+#####Using gzip compression:
+```go
+res, err := goreq.Request{
+    Method: "POST",
+    Uri: "http://www.google.com",
+    Body: item,
+    Compression: goreq.Gzip(),
+}.Do()
+```
+#####Using deflate/zlib compression:
+```go
+res, err := goreq.Request{
+    Method: "POST",
+    Uri: "http://www.google.com",
+    Body: item,
+    Compression: goreq.Deflate(),
+}.Do()
+```
+#####Using compressed responses:
+If servers replies a correct and matching `Content-Encoding` header (gzip requires `Content-Encoding: gzip` and deflate `Content-Encoding: deflate`) goreq transparently decompresses the response so the previous example should always work:
+```go
+type Item struct {
+    Id int
+    Name string
+}
+res, err := goreq.Request{
+    Method: "POST",
+    Uri: "http://www.google.com",
+    Body: item,
+    Compression: goreq.Gzip(),
+}.Do()
+var item Item
+res.Body.FromJsonTo(&item)
+```
+If no `Content-Encoding` header is replied by the server GoReq will return the crude response.
+
+## Proxy
+If you need to use a proxy for your requests GoReq supports the standard `http_proxy` env variable as well as manually setting the proxy for each request
+
+```go
+res, err := goreq.Request{
+    Method: "GET",
+    Proxy: "http://myproxy:myproxyport",
+    Uri: "http://www.google.com",
+}.Do()
+```
+
+### Proxy basic auth is also supported
+
+```go
+res, err := goreq.Request{
+    Method: "GET",
+    Proxy: "http://user:pass@myproxy:myproxyport",
+    Uri: "http://www.google.com",
+}.Do()
+```
+
+## Debug
+If you need to debug your http requests, it can print the http request detail.
+
+```go
+res, err := goreq.Request{
+	Method:      "GET",
+	Uri:         "http://www.google.com",
+	Compression: goreq.Gzip(),
+	ShowDebug:   true,
+}.Do()
+fmt.Println(res, err)
+```
+
+and it will print the log:
+```
+GET / HTTP/1.1
+Host: www.google.com
+Accept:
+Accept-Encoding: gzip
+Content-Encoding: gzip
+Content-Type:
+```
+
+
+### Getting raw Request & Response 
+
+To get the Request:
+
+```go
+req := goreq.Request{
+        Host: "foobar.com",
+}
+
+//req.Request will return a new instance of an http.Request so you can safely use it for something else
+request, _ := req.NewRequest()
+
+```
+
+
+To get the Response:
+
+```go
+res, err := goreq.Request{
+	Method:      "GET",
+	Uri:         "http://www.google.com",
+	Compression: goreq.Gzip(),
+	ShowDebug:   true,
+}.Do()
+
+// res.Response will contain the original http.Response structure 
+fmt.Println(res.Response, err)
+```
+

+# opsgenie-go-sdk
+## Aim and Scope
+OpsGenie GO SDK aims to access OpsGenie Web API through HTTP calls
+from a client application purely written in Go language.
+
+OpsGenie Go SDK covers *the Alert API*, *the Heartbeat API*,
+*the Integration API* and *the Policy API*. Future releases
+are subject to be delivered for packing more APIs soon.
+
+**Documentation:** [![](https://godoc.org/github.com/nathany/looper?status.svg)](http://godoc.org/github.com/opsgenie/opsgenie-go-sdk/client)
+
+For more information about OpsGenie Go SDK, please refer to [OpsGenie Go API](https://www.opsgenie.com/docs/api-and-client-libraries/opsgenie-go-api) document.
+
+## Pre-requisites
+* The API is built using Go 1.4.2. Some features may not be
+available or supported unless you have installed a relevant version of Go.
+Please click [https://golang.org/dl/](https://golang.org/dl/) to download and
+get more information about installing Go on your computer.
+* Make sure you have properly set both `GOROOT` and `GOPATH`
+environment variables.
+
+* Before you can begin, you need to sign up [OpsGenie](http://www.opsgenie.com) if you
+don't have a valid account yet. Create an API Integration and get your API key.
+
+## Installation
+To download all packages in the repo with their dependencies, simply run
+
+`go get github.com/opsgenie/opsgenie-go-sdk/...`
+
+## Getting Started
+One can start using OpsGenie Go SDK by initializing client and making a request. Example shown below demonstrates how to initialize an OpsGenie Alert client and make a create alert request.
+```
+    package main
+
+    import (
+    	"fmt"
+
+    	alerts "github.com/opsgenie/opsgenie-go-sdk/alerts"
+    	ogcli "github.com/opsgenie/opsgenie-go-sdk/client"
+    )
+
+    func main() {
+    	cli := new(ogcli.OpsGenieClient)
+    	cli.SetAPIKey("YOUR_API_KEY")
+
+    	alertCli, cliErr := cli.Alert()
+
+    	if cliErr != nil {
+    		panic(cliErr)
+    	}
+
+    	// create the alert
+    	req := alerts.CreateAlertRequest{Message: "Hello from OpsGenie Go Sdk"}
+    	response, alertErr := alertCli.Create(req)
+
+    	if alertErr != nil {
+    		panic(alertErr)
+    	}
+
+    	fmt.Printf("message: %s\n", response.Message)
+    	fmt.Printf("alert id: %s\n", response.AlertId)
+    	fmt.Printf("status: %s\n", response.Status)
+    	fmt.Printf("code: %d\n", response.Code)
+    }
+```
+There are many useful sample code snippets under `samples` directory for packages.
+
+## Handling Zero value problem with 'omitempty' option in Json
+
+Every golang type has a [zero value](http://golang.org/ref/spec#The_zero_value).
+AddHeartbeat and UpdateHeartbeat requests have a boolean "Enabled" field to determine a heartbeat is enabled or disabled.
+enabled is not a mandatory field in both requests so, it has "omitempty" flag.
+
+When JSON is unmarshalling the requests, it omits the fields contains zero value of its type when this option is set.
+
+The problem starts here:
+When you want to set the Enabled field as false, JSON does not unmarshal it because it contains boolean zero value and has option omitempty.
+This problem occurs with strings; when you want to reset a heartbeat's description. To set heartbeat's description as empty string, you should make the request with Description :"".
+But JSON does not unmarshal it either.
+
+So, to solve this we followed go-github's solution as mentioned [here](https://willnorris.com/2014/05/go-rest-apis-and-pointers).
+We used pointers just for booleans, if you want to set a string's value to empty. please use " ", or "-" as new string value.
+
+## The Web API

+Please follow the links below for more information and details
+about the Web API.
