Send notification to znuny aka otrs

iali · January 27, 2025, 2:18pm

Hello,

I am trying to configure notifications to send them towards my otrs ticketing system.

OTRS side the configuration is complete, CMK side however, I have a problem:

I created the following script:

#!/bin/bash

# Parametri della notifica
HOSTNAME="$1"
SERVICE="$2"
STATE="$3"
OUTPUT="$4"

# Debug: Verifica che i parametri siano passati correttamente
echo "HOSTNAME: $HOSTNAME"
echo "SERVICE: $SERVICE"
echo "STATE: $STATE"
echo "OUTPUT: $OUTPUT"

# Endpoint di Znuny
ZNUNY_API_URL="https://support.company.it/nph-genericinterface.pl/Webservice/Ticket%20REST%20API/Ticket"

# Credenziali API
API_USER="cmk"
API_PASS="9*********1"

# Creazione JSON per il ticket
JSON_PAYLOAD=$(cat <<EOF
{
    "UserLogin": "$API_USER",
    "Password": "$API_PASS",
    "Ticket": {
        "Title": "Allarme da Checkmk: $SERVICE su $HOSTNAME",
        "Queue": "[TS] Technical Support",
        "State": "new",
        "Priority": "3 normal",
        "CustomerUser": "$API_USER",
        "Type": "Monitoring Alert"
    },
    "Article": {
        "Subject": "Allarme: $SERVICE ($STATE)",
        "Body": "$OUTPUT",
        "ContentType": "",
        "CommunicationChannel": "Email",
        "Charset": "utf-8",
        "MimeType":"text/plain"
    }
}
EOF
)

# Debug: Verifica il corpo JSON
echo "JSON_PAYLOAD: $JSON_PAYLOAD"

# Invio richiesta HTTP POST
curl -u "$API_USER:$API_PASS" \
     -H "Content-Type: application/json" \
     -X POST \
     -d "$JSON_PAYLOAD" \
     "$ZNUNY_API_URL"

if I run it with
OMD[monitoring]:~/local/share/check_mk/notifications$ .notify_znuny.sh ‘icslvpl-expm-mn-01’ ‘Disk’ ‘CRITICAL’ ‘No IP packet received for 15.737259 s (deadline is 15.000000 s)’
it works, if instead I send the notification from checkmk, it goes to errorer, as it doesn’t populate the body and title.

notification logs:

A notification plugin gets the notification details via environment variables, not via command line arguments.

See the docs for details.

I saw the notifications page Notifications - via Email, SMS, ticket system and more but I can’t find the part about variables, also doing printenv with user OMD I don’t see variables for different hosts, could you provide some more details?
thanks

Have you read section 11?
