Setting Primary IP does not work

[patschi]

I have some odd behavior where the sync script is not properly setting the Primary IP on almost half of the VMs existent in netbox. The output seems to be fine:

I have cleared cache/ folder, just to rule out the cache messing up things.

In the settings, I do have configured the setting set_primary_ip to always:

; define how the primary IPs should be set
; possible values:
;
;   always:     will remove primary IP from the object where this address is
;               currently set as primary and moves it to new object
;
;   when-undefined:
;               only sets primary IP if undefined, will cause ERRORs if same IP is
;               assigned more then once to different hosts and IP is set as the
;               objects primary IP
;
;   never:      don't set any primary IPs, will cause the same ERRORs
;               as "when-undefined"
;set_primary_ip = when-undefined
set_primary_ip = always

On both vCenters:

$ grep "^set_primary_ip" settings.ini
set_primary_ip = always
set_primary_ip = always

But still, I do have 37 VMs without a Primary IP set:

Any ideas?

Hi,

Have you tried setting log level to debug2 with -l DEBUG2. It should let you know what's going on.

[bb-Ricardo]

Hey,

would you be able to checkout the latest development branch and test it again with the -l DEBUG2 option?

[patschi]

Sorry, completely lost track of this issue. I also made one strange observation: I set the Primary IP on a VM manually, removed it and it did properly set the Primary IP.

But still, when filtering for PrimaryIP=No and Status=Active, I do have a few VMs without primary IP set (2 Avi SEs are orphaned):

Running the current version in development branch doesn't change anything.

For example the decorerouter02 (01 does have a Primary IP), there are no error(s) in the logs:

$ grep "decorerouter02" debug.txt | grep -v "Parsing.*data structure.*vNIC"

Hi,

thank you for testing it again.

I'm not sure if just doing a grep on the hostname will reveal the issue. would you mind sending me the whole log (somehow secure)?

There seems to be an issue to determine which of the 6 interfaces is the one with the default route and therefore can't make an assumption which IP address should be the primary one.

This is the bit which tries to figure this out: https://github.com/bb-Ricardo/netbox-sync/blob/3c07a4c001443f50d95ae4668c931599e41efeae/module/sources/vmware/connection.py#L2218-L2239

and one of the IPs need to find into the same network and prefix as the gateway in order to be considered the primary IP address.
