Here is an example script from another thread,

var data = stream
    |from()
        .database('telegraf')
        .retentionPolicy('autogen')
        .measurement('system')
        .groupBy(*)
    |deadman(1.0, 10s)
        .id('{{ index .Tags "node" }}')
        .message('Server {{ .ID }} is OFFLINE')
        .slack()
        .stateChangesOnly()
