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.

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.
