graph templates does not match my plugin script

[sirine707]

Hello ,

I wrote a custom plugin script in order to retrieve with API , Moving average values as a line chart each at "start_date" key from json output
and "Alert" when the value is different of 0 at "start_date" as vertical line .
My question is how to modify the graph template in order for nagiosxi to parse my plugin output .
here is the output of the API i called in the plugin script :

[
    {
        "date": "25/02/2025",
        "time_blocks": [
            {
                "alert": 4,
                "logs": [
                    {
                        "positive": false,
                        "reason": "",
                        "value": "hi"
                    },
                    {
                        "positive": false,
                        "reason": "",
                        "value": "hi"
                    },
                    {
                        "positive": false,
                        "reason": "",

            }
        ],
        "validator": "Competitor Check"
    }
]

here is my plugin script logic that i want to visualize :

#!/usr/bin/env python3

import requests
import sys
import json

# Nagios status codes
OK = 0
WARNING = 1
CRITICAL = 2
UNKNOWN = 3

API_URL = "http://XXX.XXX.XX.XXX:YYYY/api/comp_check"

def main():
   try:
       response = requests.get(API_URL, timeout=30)
       response.raise_for_status()
       data = response.json()
   except requests.RequestException as e:
       print(f"CRITICAL - API call failed: {e}")
       sys.exit(CRITICAL)
   except ValueError:
       print("CRITICAL - API response is not valid JSON")
       sys.exit(CRITICAL)

   perf_data_points = []

   # Process data
   for entry in data:
       date = entry.get("date", "")
       for tb in entry.get("time_blocks", []):
           start_time = tb.get("start_time", "")
           ma_value = tb.get("moyenne_mobile", 0)
           alert_value = tb.get("alert", 0)
           retries = tb.get("retries", 0)

           timestamp = f"{date} {start_time}"
           perf_data_points.append({
               "timestamp": timestamp,
               "ma_value": ma_value,
               "alert_value": alert_value,
               "retries": retries
           })

   # Determine Nagios status
   nagios_status = OK
   if any(tb["alert_value"] > 0 for tb in perf_data_points):
       nagios_status = WARNING

   if nagios_status == OK:
       status_text = f"OK - Moving Average: {ma_value}"
   else:
       status_text = f"WARNING - Alerts detected, Moving Average: {ma_value}"

   # Format performance data for graphing
   perf_data = " ".join([
       f"'{point['timestamp']}'={point['ma_value']};1;2;0;5 'Alert'={point['alert_value']};0;0;0;10"
       for point in perf_data_points
   ])

   print(f"Competitor Check - {status_text} | {perf_data}")
   sys.exit(nagios_status)

if __name__ == "__main__":
   main()

this is the grap output :

this is what iam expecting to visualize :
orange vertical lines are Alerts when Alert!=0

I Highly appreciate your insights and feedback
