failed to send event to Alerta: Post kapacitor/alert: unsupported protocol scheme ""

druchoo commented 7 years ago

CentOS Linux release 7.2.1511 (Core)
Kapacitor 1.2.0 (git: master 5408057e5a3493d3b5bd38d5d535ea45b587f8ff)
Alerta 4.9.0

Receiving the following error when trying to alert from tick script.

[cpu_test_alerta:alert6] 2017/04/22 19:58:20 D! INFO alert triggered id:influxdb1.mycompany.com/cpu_used msg:influxdb1.mycompany.com/cpu_used:1.722827463193596 data:&{cpu map[host:influxdb1.mycompany.com] [time sigma stat] [[2017-04-22 19:58:20 +0000 UTC 0.04569644662193269 1.722827463193596]]}
[cpu_test_alerta:alert6] 2017/04/22 19:58:20 E! failed to send event to Alerta: Post kapacitor/alert: unsupported protocol scheme ""

However service-tests works and I'm able to see alert in Alerta console.

$ kapacitor service-tests alerta

kapacitor.conf

environment = "Production"

        .message('{{ .ID }}:{{ index .Fields "stat" }}')
        .info(lambda: "stat" > info OR "sigma" > infoSig)
        .warn(lambda: "stat" > warn OR "sigma" > warnSig)

    .alerta()
            .resource('Hostname or service')
            .event('Something went wrong')

What am I doing wrong?

@druchoo Your config looks correct and as you state the service test is working. I'll see if I can reproduce locally.

Hi @nathanielc, have you had a chance to look into this?

Feralus commented 7 years ago

Hi @druchoo, did you find a solution for the unsupported protocol scheme "" error? I get the same error when I try to use alerta.

druchoo commented 7 years ago

@Feralus, Unfortunately not. We're not really using Alerta anymore so I haven't followed up.

I'm having this same issue with Kapacitor 1.5.1, only I also get the error when running kapacitor service-tests alerta

I'm using url = "http://localhost:8080" because I have Kapacitor and Alerta on the same host, but if I go to that URL it outputs the JSON API, so that should be fine.

Any suggestions on how to track down where the configuration is getting lost?

FWIW, I now have this working after deleting my /var/lib/kapacitor/kapacitor.db and restarting kapacitor with the alerta-relevant sections filled in properly this time. Kapacitor would read change to the file such as [logging] level, but ignored changes I made to the [alerta] section. shrug
