REST API retrieve iLO thermal data

BradV — Mon, 28 Nov 2022 01:07:36 GMT

I'm trying to find the correct REST API call to retrieve the thermal data from iLOs. I can get it via the redfish API, but would rather like to see if I can get it directly from OneView. Using Redfish API:

i=1 TMP=$(mktemp) for SERVER in my-server-r{1..2}-n{1..12}.myorg.com; do echo "Getting thermal data from ${SERVER}" UUID=$(jq -r '.members[] | select(.serverName=="'${SERVER}'") | "\'(.uuid)"' ${HARDW} read iLOSSO iLOAuth <<< $(curl --insecure --silent --header "X-API-Version: ${currentVersion}" \ --header "auth: ${sessionID}" --request GET ${OneView}/rest/server-hardware/${UUID}/remoteConsoleUrl | \ jq -r '.remoteConsoleUrl' | sed -e 's|hplocons|https' -e 's|addr=||' -e 's|^$.*$&sessionkey=$.*$$|\1 \2') curl --insecure --silent --output thermal${i} --header "X-Auth-Token: ${iLOAuth}" --request GET ${iLOSSO}/redfish/v1/chassis/1/thermal jq '. + { "serverName": "'${SERVER}'" }' thermal${i} > ${TMP} cat ${TMP} > thermal${i} ((i++)) done # ((i--)) j=${i} THERMAL=thermal CMD="" for (( i=1; i<=${j}; i++ )); do CMD="${CMD} ${THERMAL}${i}" done cat $(echo "${CMD}") > ${THERMAL} /bin/rm ${THERMAL}? ${THERMAL}?? ${TMP} # jq -r '.serverName as $name | .Temperatures[] | { "serverName": $name,"Name":.name,"PhysicalContext":.PhysicalContext,"ReadingCelsius":.ReadingCelsius }' ${THERMAL}

If anyone has insights on how to retrieve from OneView, I'd love to hear it.

I have no idea whom posted that alert. It had nothing to do with my question. I gave a redfish example of how I retrieve iLO thermal data - not ethernet interfaces. And I asked how to get the information through the OneView REST API and not using iLO Redfish API.

Establish a session with oneview using REST client.

Add below headers.

X-API-Version - 3200 (Based on OV Version)
Content Type - application/json

Add below content to Body:

{
"userName":"Administrator",
"password":"Password"
}

Note: use the correct credentials.

Use the Method as POST and URL : POST: https://<Appliance IP>/rest/login-sessions

Response should be 200 OK.

You will get a session ID under response.
Use the session ID and another header as below.

Auth
<Session ID>

Then use the below command to retrieve the temperature of the server.

https:///rest/server-hardware//utilization?fields=AmbientTemperature&view=hour

This will retrieve the Ambient Temperature of the server per hour.

You can also change the view=day.

The output looks like this.

{
"refreshTaskUri": null,
"uri": "/rest/server-hardware/",
"resolution": 86400000,
"sliceStartTime": "2022-11-16T00:00:00.000Z",
"sliceEndTime": "2022-11-25T00:00:00.000Z",
"newestSampleTime": "2022-11-24T07:40:00.000Z",
"oldestSampleTime": "2022-11-16T03:45:00.000Z",
"isFresh": true,
"metricList": [{
"metricName": "AmbientTemperature",
"metricSamples": [
[1669248000000, 22],
[1669161600000, 21],
[1669075200000, 21],
[1668988800000, 16],
[1668902400000, 19],
[1668816000000, 22],
[1668729600000, 18],
[1668643200000, 17],
[1668556800000, 20]
],
"metricCapacity": 35
}]
}

You can also try : https:///rest/server-hardware//environmentalConfiguration

But this will not give you each and every sensor temperature as we see in ILO REST.

Hope this helps.

Thanks for that. However, it only gives the inlet ambient temperature. That only tells me how warm the air is going in to the server. Also, there is an error in the documentation: OneView REST API Reference 4200 . It shows using serial number:

GET https://{appl}/rest/server-hardware/USE7335NW3/utilization

It needs to the the UUID. I think the answer appears to be that OneView does not pull this temperature data back.

Thanks!
