[Alerts] Can not get the "resolved" messages working with RocketChat

[Ruppsn]

I set up an alert channel SLACK - (the toggle for Send resolved alerts is ON).

My Title configuration:

    [{{ .Status | toUpper -}}
    {{ if eq .Status "firing" }}:{{ .Alerts.Firing | len }}{{- end -}}
    {{ if eq .Status "resolved" }}:{{ .Alerts.Resolved | len }}{{- end -}}
    ]

My Description

    {{ range .Alerts }}
        {{- if .Annotations.description }}
            {{- "\n" -}}
            {{ .Annotations.description }}
            {{- "\n" -}}
        {{- end }}
        {{- if .Annotations.message }}
            {{- "\n" -}}
            {{ .Annotations.message }}
            {{- "\n" -}}
        {{- end }}
        {{- if .StartsAt}}
            {{- "\n" -}}
            Active since: {{ printf "%.19s UTC" (.StartsAt.String) }}
            {{- "\n" -}}
        {{- end }}
    {{- end }}

Test message is working.

I also get all the alerts i am interessted in. But i never get a resolved message.
Wasn able to figure this one out. Would be thankfull if someone can point me in the right direction.

Hi @Ruppsn,
Which version of SigNoz are you running?

[grandwizard28]

Yeah it works for me! Thinking out loud, are you sure the alert is getting resolved?

[Ruppsn]

If the condition for a resolved alert is, that the condition is triggered and went back under the threshold then yes.

[Ruppsn]

OK. Found it.
We use the Slack integration Webhook for our Rocket.Chat instance (which worked fine till a recent alertmanager update). Since it is a Slack integration and not a RC i wont expect this to work (it was just a happy coincidence that it worked). Thank you.

If someone is interessted in integrating RocketChat. It is working but you need a script to resolve the payload
Here is what i used for debugging. Thanks @puzzle

/*
 * This script is an edited form of https://github.com/puzzle/prometheus-rocket-chat/blob/master/webhook.js
 */
class Script {
  process_incoming_request({ request }) {

    // For debugging uncomment 
    //console.log(request.content);

    // Return a rocket.chat message object.
    // If channel is undefined, the default channel from the webhook configuration is used
    return {
      content: {
        //username: "hubert",
        attachments: this.getAlerts(request.content),
        channel: request.content.alerts[0].labels.rocketchat_channel
      }
    };
  }

  getAlerts(content) {
    let alertColor = this.getAlertColor(content.status);
    let attachments = [];
    let emoji = this.getEmoji(content.status);
    for (i = 0; i < content.alerts.length; i++) {
      let alert = content.alerts[i];

      attachments.push({
        color: alertColor,
        //title_link: content.externalURL,
        //title: this.getAlertTitle(alert, content.status),
        //text: alert.annotations.description,
        fields: [
        {
          title: "**Status**", value: emoji + " " + this.getAlertTitle(alert, content.status), short: true
        },
        {
          title: "**Severity**", value: alert.labels.severity, short: true
        },
        {
          title: "**Start Time**", value: alert.startsAt.substring(0,16) + " UTC", short: true
        },
        {
          title: "**End Time**", value: alert.endsAt.substring(0,16) + " UTC", short: true
        },
        {
          title: "**Description**", value: alert.annotations.description, short: false
        }
      ]
      });
    }
    return attachments;
  }

  getAlertColor(status) {
    if (status === "resolved") {
      return "green";
    } else if (status === "firing") {
      return "red";
    } else {
      return "yellow";
    }
  }

  getEmoji(status) {
    switch (status) {
      case "resolved":
        return ":white_check_mark:";
      case "firing":
        return ":warning:";
      default:
        return ":grey_question:";
    }
  }

  getAlertTitle(alert, status) {
    let title = this.getAlertStatus(alert, status).toUpperCase();
    return title;
  }

  getAlertStatus(alert, status) {
    if (status === "firing" && !!alert.annotations.severity) {
      return alert.annotations.severity;
    } else {
      return String(status);
    }
  }

}

@grandwizard28
Since i got it work with Rocket.Chat and its not that ugly, is there a possibility to contribute my settings and my .js file for people who want to integrate the alerts into RocketChat and beautify the message?
