What is my Instance ID?

Hi all,

I am new to Logic Monitor and I am working on my Python script to gather datapoints but I don't know what the Instance ID is of the data I want. How do I find this out?

Thank you,

Thomas

I should clarify:
I am doing something like this: https://companyname.logicmonitor.com/santaba/rest/device/devices/1234/devicedatasources/123456/data?start=1510918823&end=1510947623&datapoints=PercentUsed

which gives me data for many different instances like this:
"status" : 200,
  "errmsg" : "OK",
  "data" : {
    "dataSourceName" : "Data Source Name ABC",
    "dataPoints" : [ "PercentUsed" ],
    "instances" : {
      "Instance Name ABC" : {
        "values" : [ [ 46.0 ],
        "time" : [ 1510947392000 ]
      },
      "Instance Name DEF" : {
        "values" : [ [ 18.0 ] ],
        "time" : [ 1510947500000 ]
      },


 But I only want 1 of those instances, say, Instance DEF. But I need to know the instance ID. How do I find this?

Hi Thomas - 

I'd suggest having a look at https://www.logicmonitor.com/support/devices/device-datasources-instances/device-datasources-instances-overview/ to solidify the concept of "singleton" vs "multi-instance" datasources. Note that a singleton won't have an instance id, since there's only a single instance to monitor in that type of datasource.

Once you have that under your belt, have a look at https://www.logicmonitor.com/support/datasources/data-collection-methods/scripted-data-collection-overview/ to understand scripted datasource modes of operation. 

Then follow with https://www.logicmonitor.com/support/terminology-syntax/scripting-support/external-scripting/ which provides a simple example of putting together a scripted datasource.

Hope this helps.

Hi Matthew,

Thank you for your prompt reply. If it makes a difference, I should mention that I am trying to do this using a REST API call with a Python Script. Is there a way I can find out the specific instance ID through the API?

Specifically this call: 
https://companyname.logicmonitor.com/santaba/rest/device/devices/1234/devicedatasources/123456/instances/????/data?start=1510921472&end=1510950272&datapoints=PercentUsed

How can I find out what I need to put in place of ???? to make this work?

Thanks again.

Hi Thomas - You can get instance Ids for use with the REST API two ways:

1. via a GET request to the REST API instances resource for the desired datasource: https://www.logicmonitor.com/support/rest-api-developers-guide/datasource-instances/get-datasource-instances/

2. via the Info tab for the instance in the UI:

Thanks,

Sarah

That's what I was looking for!

Thanks Sarah!!!

Hey Thomas,

You need to call GET: /device/devices/{deviceId}/devicedatasources/{deviceDatasourceId}/instances and retrieve the instanceId from there and then pass the output into your call above.

I think what you are trying to do is the last example at the bottom of: https://www.logicmonitor.com/support/rest-api-developers-guide/data/get-data/
