Hello all,
I was wondering what can be done to get better output from Kapacitor when receiving email alerts.
I’ve looked around and might just need a point in the right direction for documentation. But, when for example I would like to get an alert about multiple vms with CPU usage over 50%. Am I able to get an email alert that gives clear information with variables? My current attempts look like this using “{{.Tags}}”:
“map[Session Name:VMNAME host:VMHOST]”
Any help would be appreciated!
Hello @TheEvbot3000
you get that because {{.Tags}} outputs all tags available to the script. If you want to access individual tags or fields then you can use
{{index .Tags “tagname”}} and {{index .Fields “fieldname”}}
So, {{index .Tags “Sessoion Name”}} and {{index .Tags “host”}}, or for the purpose of a message
‘Session Name: {{index .Tags “Session Name”}} host: {{index .Tags “host”}} {{index .Fields “cpu_metric”}}’
In order to use the tags, you must include them in the groupBy part of your script. hope that helps
This is great, thanks!
No problem, glad it helped.
There is some documentation about TICK syntax here which might help too.
