[Xymon] email add-on other than html_mail.pl?

[Fabian Wendlandt]

Hi Christian,

I'm using the following setup to post Xymon messages to an incoming webhook of a Teams channel.

Create a bash script send-teamsnotification.sh, replace the webhook URL and the path to the json template:
###########################################################
#!/bin/bash

# Incoming webhook of the teams channel
URI='https://outlook.office.com/webhook/<some-long-uid>@<another-uid>/IncomingWebhook/<one-more-uid>/<the-final-uid>'

# Prepend newlines with three spaces to display correctly in teams
BBALPHAMSG="${BBALPHAMSG//$'\n'/'   \n'}"

# Replace variables in the json template (replace the path to the template)
TMPFILE=$(mktemp)
envsubst < /path/to/teamsmsg.json > "$TMPFILE"

# Post message to teams channel
curl -X POST -H 'Content-Type: application/json' -d @${TMPFILE} "$URI"

rm -f $TMPFILE
###########################################################


Put the teamsmsg.json template somewhere on your xymon host, replace the Xymon hostname with your own:
###########################################################
{
    "title": "Alert for $BBHOSTSVC",
    "sections": [
        {
            "activitySubtitle": "$BBHOSTSVC is $BBCOLORLEVEL",
            "activityImage": "https://<xymon-hostname>/gifs/${BBCOLORLEVEL}.gif",
            "activityTitle": "$BBHOSTSVC",
            "activityText": "Status of service $BBSVCNAME on $BBHOSTNAME changed to $BBCOLORLEVEL"
        },
        {
            "facts": [
                {
                    "value": "$BBHOSTNAME",
                    "name": "Hostname"
                },
                {
                    "value": "$BBSVCNAME",
                    "name": "Service"
                },
                {
                    "value": "$BBCOLORLEVEL",
                    "name": "Color"
                },
                {
                    "value": "$BBALPHAMSG",
                    "name": "Message"
                }
            ],
            "title": "Details"
        }
    ],
    "potentialAction": [
        {
            "@context": "http://schema.org",
            "name": "Click here to visit the status page",
            "target": [
                "http://<xymon-hostname>/xymon-cgi/svcstatus.sh?HOST=${BBHOSTNAME}&SERVICE=${BBSVCNAME}"
            ],
            "@type": "ViewAction"
        }
    ],
    "text": "Status of service $BBSVCNAME on $BBHOSTNAME changed to $BBCOLORLEVEL"
}
###########################################################


Configure alerts.cfg to send alerts to a script recipient (the parameter 'param' is just there because Xymon expects it, it has no effect), replace the path to the script:
###########################################################
HOST=hostname.fqdn.com SERVICE=http COLOR=red
    SCRIPT /path/to/send-teamsnotification.sh param FORMAT=PLAIN
###########################################################


The resulting notification includes animated gifs of the status color, a clickable button with a link to the service page and includes an expendable status message.
You're Xymon host must be reachable via https, otherwise the gif won't display.

Best regards,
Fabian Wendlandt

Betreff: [Xymon] email add-on other than html_mail.pl?

Hello to the list,

i'm looking for another email add-on to Xymon (or another script) other than html_mail.pl which I'm currently using.
The html_mail.pl works fine, but now I'm in the situation to send emails to a MS Teams subchannel, and the result is useless, because it's totally mis-formatted in MS Teams.

I tried using the Xymon built-in mail function without html_mail.pl, but this is also not really nice, I'ld like to have at least the red / yellow / green icons together with a black background.
My knowledge isn't good enough to modify html_mail.pl to my needs.

Any idea?


Stay at home - stay healthy!
