OCI REST CDOT NODE PERFORMANCE - STARTTIME ISSUE

trentino123 — Wed, 04 Jun 2025 15:07:03 GMT

Gentlemen,

From OCI REST interface I am able to get the performace of nodes, volumes, etc, but found out the default is a week ( avg ). Trying to find out the way to limit the time of the performance response ( to last 3 hours for example ).

Links I use to get performance:

https://hoeoci01/rest/v1/assets/storageNodes/[NODE_ID]/performance?expand=history&fromTime=1488454020000&toTime=1493983620000

https://hoeoci01/rest/v1/assets/storageNodes/[NODE_ID]/performance

https://hoeoci01/rest/v1/assets/storageNodes/[NODE_ID]/performance?expand=history&since=THREE_HOURS

Does anyone know how to limit the default weekly avg with another timestart without expanding ? ( by expanding you get 15 min datapoints for 1 week !

Thanks in advance.

Trantino -

No, and yes...

OCI polls C-Mode data sources on 15min intervals

Hence you could grab the expanded output and then filter in your code for the 15min samples that you want to use.

I hope this response has been helpful to you.

I think you can construct a request like:

https://localhost/rest/v1/assets/storageNodes/27924/performance?fromTime=1465567200000&toTime=1465578000000&expand=default

Where you specify the

fromtime in Unix *milliseconds* based timestamp, as well as the toTime

The expand=default only has performance metrics for the various objects of the thing we are talking about - not the invidual samples the expand=history has.

For example, on the demo (sales) database, one of the nodes has

latency
performanceCategory	"Latency"
description	"Latency"
read
description	"Latency - Read"
unitType	"ms"
start	1465569000000
end	1465578000000
current	120
min	72
max	520
avg	297.3866566151527
sum	3152

You would want to use the "avg" latency for your use case.

I hope this helps. This is not my area of expertize, but most of the OCI folks have been travelling to Las Vegas over the last day or two - I am at 36k feet right now myself
