What does the JSON value mean?

parksm — Tue, 16 May 2023 06:37:49 GMT

Hello.

I am curious about the result of the API for future predicted values.

JSON Result
{ "timeseriesId": "com.dynatrace.builtin:pgi.jvm.usedmemory", "displayName": "JVM heap memory pool used bytes", "dimensions": [ "PROCESS_GROUP_INSTANCE", "Process ID", "poolname" ], "aggregationTypes": [ "AVG", "SUM", "MIN", "MAX" ], "unit": "Byte (B)", "filter": "BUILTIN", "detailedSource": "Infrastructure", "types": [], "dataResult": { "dataPoints": { "PROCESS_GROUP_INSTANCE-ADFF58F21CC3CABA, pid=0x1F3, poolname='Eden Space'": [ [ 1592211300000, 3292452.6211446524, -6417273.2419293225, 13092308.7955504 ], [ 1592211600000, 6529821.070899881, -8541368.499735488, 17775726.627353717 ],

JSON Result

{
"timeseriesId": "com.dynatrace.builtin:pgi.jvm.usedmemory",
"displayName": "JVM heap memory pool used bytes",
"dimensions": [
"PROCESS_GROUP_INSTANCE",
"Process ID",
"poolname"
],
"aggregationTypes": [

],
"unit": "Byte (B)",
"filter": "BUILTIN",
"detailedSource": "Infrastructure",
"types": [],
"dataResult": {
"dataPoints": {
"PROCESS_GROUP_INSTANCE-ADFF58F21CC3CABA, pid=0x1F3, poolname='Eden Space'": [
[
1592211300000,
3292452.6211446524,
-6417273.2419293225,

],
[

-8541368.499735488,
17775726.627353717
],

The top of the dataPoint is like time, but I don't know what the three data below it mean.

The usememory metric has a negative value, so I can't understand it even when I look at the document.

Hi Park,

The values returned in each instance are as follows:

[Timestamp,Predicted value,Min,Max]

You can read more about the predicted values returned through the timeseries api here: https://www.dynatrace.com/news/blog/how-to-ask-your-monitoring-system-about-the-future/

Cheers,
Jonathan
