I’m working on moving from graphite to influxdb, and I set this up: [https://github.com/jhrv/sensu-influxdb-extension](https://github.com/jhrv/sensu-influxdb-extension) and it seems to be working. My issue is that previously we were using the client hostname in the metric output, ex. (host1.cpu.usage), but it seems with Influx, I would actually want the hostname passed as a tag opposed to being in the measurement name. Does anyone know if there’s a way to use some sort of hostname variable in the sensu config so it can resolve that client’s hostname when the check is run?

Thanks.

You could use [check token substitution](https://sensuapp.org/docs/latest/reference/checks.html#check-token-substitution) and add a tags attribute with the name of the client. In your check definition you would add:

…

“tags”: {

“hostname”: “:::name:::”

}

Alternatively whatever you use to configure the client could add a [tags section in the client config](https://github.com/jhrv/sensu-influxdb-extension#tags-optional) containing the hostname and that tag would be included with every metrics result.

Awesome, that worked great. Thanks!
