Bosun Templates: Overview Embedded Templates and CSS Styles

Example

You can embed another template body into your template via {{template "mysharedtemplate" .}} to reuse shared components. Here is an example that creates a header template that can be reused at the top of all other template bodies. It also uses CSS to stylize the output so that it is easier to read. Note that any <style>...</style> blocks will be converted to inline CSS on each element so that email clients like Gmail will render the output correctly.

template header {
    body = `
    <style>
    td, th {
        padding-right: 10px;
    }
    a.rightpad {
        padding-right: 10px;
    }
    </style>
    <p style="font-weight: bold; text-decoration: underline;">
        <a class="rightpad" href="{{.Ack}}">Acknowledge</a>
        <a class="rightpad" href="{{.Rule}}">View Alert in Bosun's Rule Editor</a>
        {{if .Group.host}}
            <a class="rightpad" href="https://opserver/dashboard/node?node={{.Group.host}}">View {{.Group.host}} in Opserver</a>
            <a href="http://kibana/app/kibana?#/discover?_g=(refreshInterval:(display:Off,pause:!f,value:0),time:(from:now-15m,mode:quick,to:now))&_a=(columns:!(_source),index:%5Blogstash-%5DYYYY.MM.DD,interval:auto,query:(query_string:(analyze_wildcard:!t,query:'logsource:{{.Group.host}}')),sort:!('@timestamp',desc))">View {{.Group.host}} in Kibana</a>
        {{end}}
    </p>
    <table>
        <tr>
            <td><strong>Key: </strong></td>
            <td>{{printf "%s%s" .Alert.Name  .Group }}</td>
        </tr>
        <tr>
            <td><strong>Incident: </strong></td>
            <td><a href="{{.Incident}}">#{{.Last.IncidentId}}</a></td>
        </tr>
    </table>
    <br/>
    {{if .Alert.Vars.notes}}
        <p><strong>Notes:</strong> {{html .Alert.Vars.notes}}</p>
    {{end}}

    <p><strong>Tags</strong>
    <table>
        {{range $k, $v := .Group}}
            {{if eq $k "host"}}
                <tr><td>{{$k}}</td><td><a href="{{$.HostView $v}}">{{$v}}</a></td></tr>
            {{else}}
                <tr><td>{{$k}}</td><td>{{$v}}</td></tr>
            {{end}}
        {{end}}
    </table></p>
    `
}
