That does not appear to be the full error, if you don’t mind can you please copy the surrounding logs so we can further see what the issue is.

Can you get an example of the payload sent? Looks like the property alerts might be missing

Thank ou from your response

{ receiver: ‘rocketchat’, status: ‘firing’, alerts: [ { status: ‘firing’, labels: [Object], annotations: {}, startsAt: ‘2018-05-29T14:08:57.860711149+03:00’, endsAt: ‘0001-01-01T00:00:00Z’, generatorURL: ‘[http://a.b.c.d:9090/graph?g0.expr=up{job%3D"node"}+%3D%3D+0&amp;g0.tab=1](http://a.b.c.d:9090/graph?g0.expr=up%7Bjob%3D%22node%22%7D+%3D%3D+0&amp;g0.tab=1)’ } ], groupLabels: { alertname: ‘InstanceDown’ }, commonLabels: { alertname: ‘InstanceDown’, instance: ‘a.b.c.d:9100’, job: ‘node’ }, commonAnnotations: {}, externalURL: ‘http://a.b.c.d:9093’, version: ‘4’, groupKey: ‘{}:{alertname=“InstanceDown”}’ }

This is alert sended from alertmanager
All settings are done from example gived in githud(prometheus and alertmanager)
I see on youtube an example which works, but Rocket Chat is version 0.63.3
I use 0.64.2(I believe) and upgraded to 0.65
And don’t work

Hi
try config alert manager

Alert for any instance that is unreachable for >5 minutes.

  • alert: InstanceDown
    expr: up == 0
    for: 5m
    labels:
    severity: page
    annotations:
    summary: “Instance {{ $labels.instance }} down”
    description: “{{ $labels.instance }} of job {{ $labels.job }} has been down for more than 5 minutes.”

Alert for any instance that has a median request latency >1s.

  • alert: APIHighRequestLatency
    expr: api_http_request_latencies_second{quantile=“0.5”} > 1
    for: 10m
    annotations:
    summary: “High request latency on {{ $labels.instance }}”
    description: “{{ $labels.instance }} has a median request latency above 1s (current value: {{ $value }}s)”
