Prometheus query_range how to set start and end date and have one calculated and sum value of domains

I googled as much as I could to find and reach what I’m going to have, but I have some problems.

I downloaded libvirt_exporter on instance1.mysite.com to have the values of how much each VM downloads and uploads.

This is my code:

import requests
response_tmp =requests.get(
    'http://prom.mysite.com:9091/api/v1/query_range',
    params={
        'query': 'sum(increase(libvirt_domain_interface_stats_receive_bytes_total[2h]))',
        'start': '2024-10-01T00:00:00.000Z', # RFC3339, UTC
        'end':   '2024-10-13T00:00:00.000Z', # RFC3339, UTC
        'step':  '60'
        },
        auth=('admin', 'myStrongAdminPassWord')
        )#.json()['data']['result']

This is current result:

{"status":"error","errorType":"bad_data","error":"exceeded maximum resolution of 11,000 points per timeseries. Try decreasing the query resolution (?step=XX)"}

But if I change the start-end to a newer start date like 2024-10-12T00:00:00.000Z, it is something like this:

{
  "status": "success",
  "data": {
    "resultType": "matrix",
    "result": [
      {
        "metric": {
          "domain": "instance-0000017d",
          "instance": "instance1.mysite.com:9177",
          "job": "libvirt_exporter",
          "target_device": "tapc1aedd0e-fd"
        },
        "values": [
          [1728722820, "13668737203.838501"
          ],
          [1728722880, "20305044171.814877"
          ],
          [1728722940, "26668580969.595806"
          ],
          [1728723000, "33146620341.0449"
          ],
          [1728723060, "40289211402.494484"
          ],
          [1728723120, "46987842952.288124"
          ],
          [1728723180, "53823854756.43225"
          ]
        ]
      }
    ]
  }
}

But as I understood, the increase function does this: 13668737203.838501 + 20305044171.814877 + 26668580969.595806 + 33146620341.0449 + 40289211402.494484 + 46987842952.288124 + 53823854756.43225, but I see all the values.

I’m going to have 234889891797.5089 which is the sum of all above numbers.

Would you please help me regarding this?
