Bosun Templates: Graph and GraphAll Graph using Alert Variable
Example
Using .Graph will filter the results to only include those that match the tagset for the alert. For instance an alert for os.low.memory{host=ny-web01} would only include series with the host=ny-web01 tags. If multiple series match then only the first matching result will be used.
template graph.template {
subject = ...
body = `{{template "header" .}}
<strong>Graph</strong>
<div>{{.Graph .Alert.Vars.graph}}</div>
<strong>Graph With Y Axis Label Literal</strong>
<div>{{.Graph .Alert.Vars.graph "Free Memory in GB"}}</div>
<strong>Graph With Y Axis Label From Variable</strong>
<div>{{.Graph .Alert.Vars.graph .Alert.Vars.graph_unit}}</div>
`
}
alert os.low.memory {
template = graph.template
...
$graph = q("avg:300s-avg:os.mem.percent_free{host=$host}", "1d", "")
$graph_unit = Percent Free Memory (Including Buffers and Cache)
...
}
