UniFi AP Retries Stopped Working

[jordanwmcdonald]

CONFIGURATION

• Zabbix 7.0.0
• Ubuntu Server 24.04 LTS VM

ISSUE

• All functions of the UniFi AP template were working well until about 5 days ago (I suspect it was related to an update to the AP firmware, but rolling back the AP firmware did not resolve it.).
• Everything still works except for the Wi-Fi Retries Item.

ATTEMPTED RESOLUTIONS

• I did my best to dive into the Templates and compare the Keys with what I was seeing when I ran mca-dump directly SSH'd into an AP, but I could not figure it out.
• Tailing /var/log/zabbix/zabbix_server.log and /tmp/mcaDumpShort.err did not reveal any issues.

Please see attached screenshot showing the Last 7 days in Zabbix and let me know I can assist.

Thank you, Jordan

ack - I definitely see the problem here as well..

[patricegautier]

Try this latest committed AP template , let me know if that fixes it..

[jordanwmcdonald]

Thank you for your response and commit.

The issue remains - likely because of an oversight on my part. Here is what I did:

1. Verified that I overwrote the old templates during import
2. Removed an AP Host in Zabbix and added it back
3. Rebooted the Ubuntu 24 VM dedicated to Zabbix
4. Waited 6+ hours
5. Verified that the Widget was configured correctly

The 'Last value' shows as '0' each time I checked on it.

Ok let's check a couple of things:

In Zabbbix, looking at the list of items for one of the APs not reporting correctly, do you see any red error marks, or even orange (no longer discovered) marks?

anything in the zabbix server logs about that AP?

can you check the 'Unifi AP' template and make sure it's up to date by sending me the preprocessing screen for its active radio discovery rule?

[jordanwmcdonald]

Regarding your first request for marks, I currently do not see any red or orange marks. However, about 10 minutes ago I did, but got sidetracked before I could document them. Upon refreshing the screen several times over the last 10 minutes I have not seen the marks reappear. From memory, the three 'Channel Retries' Items for 6e/na/ng had red marks which, when hovered over, indicated a Timeout. For background, when I first encountered this issue last week I followed your guide's steps on increasing the timeout values in the two locations you indicated so, theoretically, timeouts should not be an issue (unless there's some underlying problem with my network in the lower OSI layers). There were many other items that, at that time, had red marks (none had orange marks). Again, from memory, when I hovered over anything other than 'Channel Retries' these Items had a much longer error message related to mca-dump.

Evaluating '/var/log/zabbix/zabbix_server.log' reveals this sequence repeating every 10-15 minutes:

So the template was correctly updated..  It’s a little bit worrisome that you see a timeout every 10-15mns to 10.24.10.42.  Did you also up the overall zabbix timeout in your zabbix server config? -PSent from my iPadOn Jul 14, 2024, at 6:10 PM, Jordan McDonald @.***> wrote: Regarding your first request for marks, I currently do not see any red or orange marks. However, about 10 minutes ago I did, but got sidetracked before I could document them. Upon refreshing the screen several times over the last 10 minutes I have not seen the marks reappear. From memory, the three 'Channel Retries' Items for 6e/na/ng had red marks which, when hovered over, indicated a Timeout. For background, when I first encountered this issue last week I followed your guide's steps on increasing the timeout values in the two locations you indicated so, theoretically, timeouts should not be an issue (unless there's some underlying problem with my network in the lower OSI layers). There were many other items that, at that time, had red marks (none had orange marks). Again, from memory, when I hovered over anything other than 'Channel Retries' these Items had a much longer error message related to mca-dump.

So the template was correctly updated..  It’s a little bit worrisome that you see a timeout every 10-15mns to 10.24.10.42.  Did you also up the overall zabbix timeout in your zabbix server config?

I am not 100% sure what I changed that fixed it, but I believe the resolution was factory resetting all APs and re-adopting them. And, no, I had not modified any of the global Zabbix server timeouts.

Thank you for your help and thanks again for this amazing tool.
