elasticsearch - How do I deal with timestamp in bosun configuration? -

i'm trying insert alert in elasticsearch bosun don't know how fill variable $timestamp (have @ example) present time. can use functions in bosun.conf? i'd now(). can me, please?

this extract of example configuration:

macro m1 {     $timestamp = **???** } notification http_crit {     macro = m1     post =  http://xxxxxxx:9200/alerts/http/     body = {"@timestamp":$timestamp,"level":"critical","alert_name":"my_alert"}     next = http_crit     timeout = 1m } alert http {     template = elastic     $testhttp = lscount("logstash", "", "_type:stat_http,http_response:200", "1m", "5m", "")     $testavghttp  = avg($testhttp)     crit = $testavghttp < 100     critnotification = http_crit } 

we use .state.touched.format renamed .last.time.format in master branch. format string go time format, , have print correct format elastic expecting.

template elastic {     subject = `time: {{.state.touched.format "15:04:05utc"}}` } //changed on 2016 feb 01 template elastic {     subject = `time: {{.last.time.format "15:04:05utc"}}` } 

which when rendered like:

time: 01:30:13utc
