NimbostratusWhat's the Best Way to Derive a Device-Group Name Over REST?
In order to create some scaleable BigIP automation, I need to be able to sync my active and standby balancers. To do this, I need to know the name of the device group. I've been using JQ to filter the output from https://active-balancer.mydomain.com/mgmt/tm/cm/syncStatus/
I have to upload an image, because devcentral's flagging my post as spam:
This isn't ideal, but I guess if I can always rely on the description for to contain the device group, I can parse it out with JQ. Is there a better way to get the desired string, which, in this case, is FOO-BAR-LB (see highlight in image)? Indeed, if there's a better approach to syncing an active:failover pair when you don't know the name of the device group, I'm all ears! Thanks.

Are you trying to pull just the Traffic group out of the output?
Ed_SummersI use the Python SDK so I may not be able to get you exactly there, but hopefully can help a bit.
There is a device_groups sub-collection under /mgmt/tm/cm. I just checked a cluster that is running a single traffic-group, and it has three device-groups: gtm, the device_trust_group, and the sync-failover group containing the traffic group.
There may be a better way to pull the desired device-group from that list. In my case the desired group is the only one of type sync-failover (the others are sync-only).
syncretismI suppose I am. As it stands, I have to pull sync status to get the name of the device group, which I then use to sync the group with another rest call:
POST -d '{"command":"run","utilCmdArgs":"config-sync to-group FOO-BAR-LB"}'
Then I check sync status again to confirm that the sync took place. I haven't found another way to get this group name programmatically, but I'm not an f5 admin.
