  1. Hi Cole, predef.* attributes are used by our Topology Service and can't be updated through the API, only through LogicModules. They aren't specific to Azure as they may be applied to standard devices as wel To update a device with Properties and not affect others you'll want to update the device using PATCH command documented here: Pay particular attention to the customProperties opType option. Note: I haven't looked through the code. I'm just offering this based on the last two posts. ~Forrest
  2. Yes. ABCG can properly address collectors of different sizes. The JVM memory value is used to determine how many instances should be assigned to each collector. The configured threshold is used for Medium collectors and the value is scaled up/down.
  3. In my tests I had to wrap the preferredCollectorId value of zero in double quotes: { "name": "", "displayName": "My Device", "autoBalancedCollectorGroupId": 4, "preferredCollectorId": "0" } I acknowledge it's not really consistent with the other ID value for the Collector Group, but give it a try and let me know. ~Forrest
  4. Seems reasonable. I've added a Feedback ticket in our system to track this for upcoming sprints. ~Forrest
  5. Thanks for the idea guys. I saw your Feedback tickets come in that were submitted through your portal and I'll look into how we might be able to accomplish this. ~Forrest
  6. While you pass 0 to set it to AutoBalanced the actual collector that is currently doing the monitoring will be represented in the return value for 'preferredCollectorId' I'd have to try and test your specific scenario and potentially confirm with the developers to see how it would respond.
  7. If you are changing the collectorId within Auto Balanced Collectors there are some other "rules" to follow. If you want to switch a device from being Auto Balanced to directly assigned you have to set `autoBalancedCollectorGroupId` to 0 and `preferredCollectorId` to the collector ID you want it directly assigned to. To set it back to AutoBalanced from directly assigned do the reverse: `autoBalancedCollectorGroupId` sets to id of the group and `preferredCollectorId` to 0 With Version 2 of the API you don't need the $queryparam part. You can just patch with the payload.
  8. Thanks for the feedback. I'm confused why user logins would have such an impact on a collector, but I look forward to seeing your datasource.
  9. When you enable Auto Balanced Collectors on a Collector Group a new column is added with the instance count. I do have an enhancement on the list to always show this count rather than only on Auto Balanced Groups.
  10. Few clarifications around the Auto Balanced Collector solution and when it chooses to balance devices: The AutoBalance is intentionally conservative because when devices are moved between collectors there is a risk of them missing polls. The balancing activity will not trigger a rebalance (even if the button is pushed) if the collector is not over it's own unique threshold limit. In the current iteration, all instance types are treated equally. Since collectors of different sizes can handle different loads we set the default threshold to 10,000 as the number of instances threshold for 2GB of JVM memory, which corresponds to a medium sized collector. The math to determine how many actual instances a collector can handles is the following: (Target_Collector_Mem/Medium_Mem)^1/2 * Medium_Threshold For example, if user sets (2G) collector's threshold to 10,000, for a large(4G) collector, the threshold will be scaled to: (4/2)^1/2 * 10000 = 14140 I checked out your current collectors and none of them are over their corresponding thresholds. The biggest one only had 12,209 instances on a large collector. As for adding devices if you want to add a new device to an AutoBalance Collector Group without choosing the collector the payload below would be a very minimal example to do that. The key parts being the autoBalancedCollectorGroupID is provided as an integer and 'preferredCollectorId' is set to 0 for the device to be AutoBalanced. This should add the device to the collector with the lowest instance count. To create a new device POST to .../device/devices on V2 of the REST API { "name": "", "displayName": "My Device", "autoBalancedCollectorGroupId": 4, "preferredCollectorId": "0" } ~Forrest
  11. We just finished with LevelUp. I'll connect with Support to review the issues you were running into and get back to you tomorrow (Friday)
  12. Hey Cole, Are you having trouble with the newly released Auto Balanced Collectors feature? If so please open a ticket so we can look into it and help. ~Forrest
  13. Hi Akash, We are close to releasing a new feature that will include functionality to spread fail-over of devices among multiple collectors. ~Forrest
  14. Hi DarrylG, I've added this as a feedback ticket in our feature request queue. I believe a few customers might have done this previously. If I can find details I'll reshare them here. ~Forrest
  15. Our official ServiceNow CMDB Integration is now available.
