Dear all,
I want to have aggregations over the statistics but I don't know how
to do aggregations. I have a test query as follows:
{
"end_time": "now",
"select_fields": [
"T", "cpu_info.cpu_share", "SUM(cpu_info.cpu_share)",
"cpu_info.one_min_cpuload", "UUID", "COUNT(cpu_info)"
],
"sort_fields": [],
"start_time": "now-60m",
"table": "StatTable.ComputeCpuState.cpu_info",
"where": [
[
{
"name": "Source",
"op": 1,
"suffix": null,
"value": "contrail",
"value2": null
}
]
]
}
I send this query and I get around 12 instances with the information I
requested. However, the count is 1 in each instance and the SUM is
equal to de cpu_share (as it represents only 1 value). How can I have,
for example, an aggregation over 3 (i.e. a count equal to 3)? Is it
configured somewhere in contrail configuration?
Also, if you could provide me which kinds of aggregations are
available I would be grateful. Are they the same as the aggregations
available at Cassandra?
Thank you for reading.
Best regards,
Alberto.
