servers

README

This directory is for helper servers available for use with Cloudprober. Cloudprober itself is a prober daemon with primary purpose to run probes but since it runs on all of our probing VMs, it provides a perfect platform to run servers that can act as the backend for probes that need to access something on cloud.

Overview

Package servers provides an interface to initialize cloudprober servers using servers config.

Index

• Variables
• type Server
• type ServerInfo
  • func Init(initCtx context.Context, serverDefs []*configpb.ServerDef) (servers []*ServerInfo, err error)

Variables

var StatusTmpl = template.Must(template.New("statusTmpl").Parse(`
<table class="status-list">
  <tr>
    <th>Type</th>
    <th>Conf</th>
  </tr>
  {{ range . }}
  <tr>
    <td>{{.Type}}</td>
    <td>
    {{if .Conf}}
      <pre>{{.Conf}}</pre>
    {{else}}
      default
    {{end}}
    </td>
  </tr>
  {{ end }}
</table>
`))

StatusTmpl variable stores the HTML template suitable to generate the servers' status for cloudprober's /status page. It expects an array of ServerInfo objects as input.

Types

type Server

type Server interface {
	Start(ctx context.Context, dataChan chan<- *metrics.EventMetrics) error
}

Server interface has only one method: Start.

type ServerInfo

	Server
	Type      string
	ServerDef *configpb.ServerDef
	Conf      string
}

func Init

func Init(initCtx context.Context, serverDefs []*configpb.ServerDef) (servers []*ServerInfo, err error)

Init initializes cloudprober servers, based on the provided config.
