webhook response status 400 bad request

[ricklagerweij]

Hi @gmauleon,

Currently configuring the alert from prometheus to the webhook but I'm getting a 400 bad request.

Alertmanager logs; level=debug ts=2018-09-20T11:53:57.096317774Z caller=notify.go:668 component=dispatcher msg="Notify attempt failed" attempt=1 integration=webhook receiver=zabbix err="unexpected status code 400 from http://10.72.52.106:8080/alerts"

Is the zabbix-alertmanager-webnhook still working properly with the latest alertmanager?

[ricklagerweij]

@gmauleon missing some of the json formats e..g.

{ "version": "4", "groupKey": , // key identifying the group of alerts (e.g. to deduplicate) "status": "<resolved|firing>", "receiver": , "groupLabels":

Thanks for the heads-up, I'll try to have a look later this week

[ricklagerweij]

@gmauleon we fixed it, works in my fork thanks anyway;)

[gmauleon]

Hum actually I think you probably got lucky there, I don't think the missing fields are the problem. It's the way I was handling alerts as a group only instead of individual alerts which is completely wrong :)

I bet if you fire up multiple alerts at the same time you'll have the problem again.

[gmauleon]

@ricklagerweij if you ever have time, try out the last release, should handle multi alerts the way it always should have.

Awesome @gmauleon! We did indeed get issues by sending multiple alerts, solved by your latest commit :)

Currently the alertmanager only sends data to the webhook when a trigger hits it threshold, how would it be possible in any way to send a 0 value to zabbix when no data is send from alertmanager?

[gmauleon]

Hum, I don't think it's really the job of an alertmanager webhook though, it's purpose is only to forward alerts to whatever backend it supports. You could handle that case direcly at the source, like having different rules for when Prometheus can't scrap a target or when there is absent data there and have a different item in Zabbix for those.

Hi @gmauleon

I'm still getting 400 when trying to test the webhook. I'm using it on kubernetes (latest image tag). Could you please give me some directions to get it working?

[gmauleon]

Hi there, Sorry I'm not looking much at this project anymore those days. I`ll try to have a look with the latest alertmanager somewhere this week, see if there is a quick win.

Hey @pauloeliasjr,

Just gave it a try with the latest alertmanager and I don't see any problems. Do you have more context for your 400? Any logs from the webhook? The configuration you are using might help too.

Thanks Gael
