mca-dump-short script timeout on UDM-SE

[Just-Insane]

When attempting to run the mca-dump-short script after configuring SSH keys, I keep getting a timeout error. I have tried both the script from the Main branch and the last tagged release. The exact error message is:

{ "mcaDumpError":"Error", "reason":"time out with exit code 137", "device":"10.0.1.1" }

I'm not sure if it's having an issue parsing any differences between an UDMP and UDM-SE, but I don't think there are that many?

Also, I tried setting the timeout flag to 30 seconds, with the same result. The script times out.

I've also tried updating the timeout options mentioned in the README. The error log in zabbix_server.log is:

Failed to execute command "/usr/lib/zabbix/externalscripts/mca-dump-short.sh '-d' '10.0.1.1' '-u' 'root' '-i' '/var/lib/zabbix/.ssh/zabbix/zb_id_rsa' '-t' 'UDMP' '-p' '{$UNIFI_SSHPASS_PASSWORD_PATH}' '-o' '15' '-b'": Timeout while executing a shell script.

I've also tried setting {$UNIFI_SSHPASS_PASSWORD_PATH} to null in the Zabbix UI, and that did not help. (Not sure if that's needed)

have you tried running that command by hand without the final -b from the zabbix server?

Yes, I’ve tried the manual command on the server and it does not provide any more information even with the verbose flag set.

I have a UniFi Switch that I configured and it worked instantly once I updated the SSH settings in the UniFi app.

I know the UDM-SE doesn’t use the same ssh settings as the UniFi app, but I did confirm that SSH via keys works from the Zabbix server appliance as the zabbix user.

Hmm. Looks like disabling SSH on the UDM, re-enabling and setting a new password, then rebooting has resolved the issue.

I rebooted due to noticing the UDM stuck in "Getting Ready", so I suspect it'd been an issue since the initial configuration.
