Contact Routing

Sensu Go
,
1

Hi Folks, first time poster looking for some help!

I’m attempting to configure contact routing in our Sensu Go 6 installation as per https://docs.sensu.io/sensu-go/latest/observability-pipeline/observe-filter/route-alerts/

I’m deploying into a protected environment, so I have no internet access, and am storing assets in an artifactory repo.

As far as I can tell I’ve done everything needed but I’m getting this error in the log every time the filter is called -

sensu-backend: 
{
"component":"pipelined",
"error":"ReferenceError: 'has_contact' is not defined",
"level":"error",
"msg":"error evaluating javascript event filter",
"time":"2020-09-25T10:07:47+01:00"
}

I’m now getting three alerts per event, as it doesn’t seem to be able to identify the has_contact value in the filter, and is routing through all three email-handlers that I have set in my handler set.

Any guidance would be much appreciated.

Thanks.

@giinge121 can you provide your check, filter, and handler definitions?

I think I’ve resolved this issue now. I was loading the “build” assets into my local repo, not the “release” asset and so the content of the asset was completely wrong. Having realised my mistake and updated my repo everything just clicked into place.

Thanks,
Mark.
