NULL values in Uplink Performance - /api/v1/organizations/{organizationId}/uplinksLossAndLatency

We are using this endpoint for one of our solutions -/api/v1/organizations/{organizationId}/uplinksLossAndLatency
Sometimes the uplink value shows "NULL" . It possibly means that the uplink port is down or failed over but there are performance metrics still alive. For instance
{ "networkId": "L_647955396387936173", "serial": "Q2QN-SJJP-8KA7", "uplink": null, "ip": "10.2xx.2.1x",

"timeSeries": [

{ "ts": "2020-11-13T17:58:45Z", "lossPercent": 0.0, "latencyMs": 125.0 },

{ "ts": "2020-11-13T17:59:44Z", "lossPercent": null, "latencyMs": null },

{ "ts": "2020-11-13T18:00:44Z", "lossPercent": 100.0, "latencyMs": 0.0 },

{ "ts": "2020-11-13T18:01:44Z", "lossPercent": null, "latencyMs": null },

{ "ts": "2020-11-13T18:02:44Z", "lossPercent": null, "latencyMs": null } ] }

 

I presume this means we could ignore this Uplink port and not act on it ? Just needed clarification on this 

 

Question 1: - what does a NULL uplink value in perf stats endpoint really mean and could we ignore the stats when its NULL

 

also request some clarifications on the following results.

 

Few of the uplink stats results from the `uplinksLossAndLatency` end point have the same IP but different uplinks and serial numbers  

"networkId": "L_647955396387935591",

    "serial": "Q2QN-L75M-VXN3",<---

    "uplink": "wan1",

    "ip": "192.84.xx.11",

    "networkId": "L_647955396387935591",

    "serial": "Q2QN-L75M-VXN3",

    "uplink": "wan2",

    "ip": "192.84.xx.11",

 

 

    "networkId": "L_647955396387935591",

    "serial": "Q2QN-Z7PG-E3DF",<---

    "uplink": "wan2",

    "ip": "192.84.xx.11",

    "networkId": "L_647955396387935591",

    "serial": "Q2QN-Z7PG-E3DF",

    "uplink": "wan1",

    "ip": "192.84.xx.11",""

 

xx are al the same above

and some results have same Uplink name and Serial number but different IP addresses

 

{ "networkId": "L_647955396387936173",

"serial": "Q2QN-6QQK-J2L5", <-

"uplink": "wan1", <-

"ip": "182.74.17.1",<-----------------------IP1-----------

"timeSeries": [ { "ts": "2020-11-13T17:58:16Z", "lossPercent": 0.0, "latencyMs": 45.2 },

 ] }

{ "networkId": "L_647955396387936173",

"serial": "Q2QN-6QQK-J2L5",<-

"uplink": "wan1", <-

"ip": "182.74.17.147",<-----------------------IP2-----------

"timeSeries": [ { "ts": "2020-11-13T17:58:16Z", "lossPercent": 0.0, "latencyMs": 46.5 },] }

 

Question 2:

What is the relationship between serial number , IP and uplink name . We know uplink values could be only the follow 4 values- wan1 , wan2 , cellular and NULL. but unsure on when the two possible cases mentioned above occur. (same uplink/serial , diff IP and same ip , diff uplink/serial)

 

Thanks for your time .

Hi @ag_scilo !

 

Thanks for posting in our community. Given there seem to be some specifics in this post to your networks and the Dashboard, my suggestion would be to submit a case to our support team via Dashboard. That way we can look at the data you are pulling along with context from the devices and Dashboard. You can include attachments to the case if there is additional examples or data you want them to have.

 

To submit a case in Dashboard:

  1. Log-in to Dashboard
  2. Navigate to "?" > Get help > Still need help? > Submit an email case.
  3. Use the provided fields to explain the question or issue. Please include any relevant details.
  4. Click Submit.

Thanks. This was posted by someone on my team. We aren't a customer, but a partner building this out for a customer. I'm not sure we are able to open support cases on behalf of our customers.

Hi Taylor,

 

Whoever your customer is can open the case. When they receive the case opened email they can reply all and CC you or whomever else is relevant so you can communicate with support about the issue. 

 

The only time I think I would expect a null is if the polling for a device is new (eg, you've added a new destination to poll within the last few minutes). There could be some other scenarios though.

Hi @ag_scilo @TaylorJohnson , did you get an answer to question 1? We are seeing this, though not often. But it seems not related to actual link state

 

Kind regards, Frank

I don't believe we did.
