Hi All,
I am trying to calculate the derivative of a *counter* metric
iface_send_bytes_total. More specifically:
requests.get(
"http://{}:{}/api/v1/query_range".format(
os.environ["IXONE_PROMETHEUS_HOST"],
os.environ["IXONE_PROMETHEUS_PORT"],
),
params={
"query": """ {}{{job="{}",asn="{}"}} """.format(
metric, "ixone", asn
),
"start": arrow.now().shift(minutes=-30).int_timestamp,
"end": arrow.now().int_timestamp,
"step": "300s",
},
timeout=10,
).json()
returns
{'status': 'success',
'data': {'resultType': 'matrix',
'result': [{'metric': {'__name__': 'iface_send_bytes_total',
'asn': 'xxx',
'asn_text': 'xxx',
'host_name': 'de-fra05a-ri1',
'iface_name': 'xe-18/1/3.0',
'instance': 'x.x.x.x:19089',
'job': 'ixone'},
'values': [[1617036082, '71509706701310'],
[1617036382, '71568383292303'],
[1617036682, '71631728237264'],
[1617036982, '71695503709290'],
[1617037282, '71758877231912'],
[1617037582, '71824964130577']]},
{'metric': {'__name__': 'iface_send_bytes_total',
'asn': 'xxx',

'host_name': 'nl-ams04a-ri3',
'iface_name': 'ae41.0',

[1617036982, '94407464686040'],
[1617037282, '94530315906559'],
[1617037582, '94656350955927']]},
{'metric': {'__name__': 'iface_send_bytes_total',
'asn': 'xxx',
'asn_text': 'xxx',
'host_name': 'nl-ams09c-ri1',
'iface_name': 'ae41.0',
'instance': 'x.x.x.x:19089',
'job': 'ixone'},
'values': [[1617036082, '2723097803324973'],
[1617036382, '2723265785973945'],
[1617036682, '2723436688981251'],
[1617036982, '2723610306174213'],
[1617037282, '2723782018282656'],
[1617037582, '2723957898915806']]}]}}
*When* I try to calculate the derivative based on 5min interval to come up
with the traffic in bits/sec using
requests.get(
"http://{}:{}/api/v1/query_range".format(
os.environ["IXONE_PROMETHEUS_HOST"],
os.environ["IXONE_PROMETHEUS_PORT"],
),
params={
"query": """ (8 * irate({}{{job="{}",asn="{}"}}[5m])) """.format(
metric, "ixone", asn
),
"start": arrow.now().shift(minutes=-30).int_timestamp,
"end": arrow.now().int_timestamp,
"step": "300s",
},
timeout=10,
).json()
returns
{'status': 'success', 'data': {'resultType': 'matrix', 'result': []}}
Can you advise maybe what I am doing wrong?
