Calculation of HTTP Agent Value

[JamesPickup]

I am attempting calculate an average from an HTTP Agent set of values, by 2 hours of Googling has left me more confused, so any help appreciated please.

HTTP Agent returns the following every 5 mins:

2024-09-06 09:55:58
<channelStatistics>
<serverId>06234d23-82cc-4764-a63f-6f5d1dee0e08</serverId>
<channelId>53dbc431-4df0-4dba-9da7-4c8f214a9bfa</channelId>
<received>4937</received>
<sent>4572</sent>
<error>139</error>
<filtered>0</filtered>
<queued>0</queued>
</channelStatistics>

I would like to calculate the average of the received number over the last hour.

Failed calculations I have tried

avg(/vmd1lmirthapp1/Channel.53dbc431-4df0-4dba-9da7-4c8f214a9bfa[<received>,values],1h)
avg(/vmd1lmirthapp1/Channel.53dbc431-4df0-4dba-9da7-4c8f214a9bfa[/,<received>],1h)

[cyber]

avg(/vmd1lmirthapp1/vmd1lmirthapp1.Received,1h)
that looks like, it should work..
function(/host/key,<parameter1>,<parameter2>,...)

Same syntax should be good for a trigger calculation also.

You are trying to parse that data file directly in calculated item? What gave you that kind of idea?
First you should split arrived data into dependentitems and then you can calculate your averages...

[JamesPickup]

Thank you. ok, so I have already done that failed with the calculation there too.

the dependant item returns this set of information (last hour):

Timestamp vmd1lmirthapp1.Received
2024-09-06 11:20:57 4939
2024-09-06 11:15:58 4937
2024-09-06 11:10:57 4937
2024-09-06 11:05:58 4937
2024-09-06 11:00:57 4937
2024-09-06 10:55:58 4937
2024-09-06 10:51:03 4937
2024-09-06 10:45:58 4937
2024-09-06 10:41:01 4937
2024-09-06 10:35:57 4937
2024-09-06 10:30:57 4937
2024-09-06 10:25:57 4937

and I have tried these calculations that all error. Clearly I dont know what I am doing, but I think I am close ;-)

avg(/vmd1lmirthapp1/vmd1lmirthapp1.Received[values,vmd1lmirthapp1.Received],1h)
avg(/vmd1lmirthapp1/vmd1lmirthapp1.Received[vmd1lmirthapp1.Received],1h)
avg(/vmd1lmirthapp1/vmd1lmirthapp1.Received,1h)

avg(/vmd1lmirthapp1/vmd1lmirthapp1.Received,1h)

function(/host/key,<parameter1>,<parameter2>,...)

Apologies, it does work when using the relevant syntax of an older version. I am very sorry for troubling you.
