Script will not work in Zabbix
DRK-Boll opened this issue · 9 comments
Hi Patrice,
i want to install your Script to monitor our Unifi devices.
So i install everything in the readme:
sudo -u zabbix ssh -i yourUserName@oneOfYourUnifiDevicesIP --> This works fine
sudo -u zabbix /usr/lib/zabbix/externalscripts/mca-dump-short.sh -d -u -i -t <UDMP|AP|SWITCH|CK> --> This works also
When i then in Zabbix i create a host, I have the following problem
Preprocessing failed for: /usr/lib/zabbix/externalscripts/mca-dump-short.sh: Ungültige Option -- b.Usage /usr/lib/zabbix/ex...
- Result: /usr/lib/zabbix/externalscripts/mca-dump-short.sh: Ungültige Option -- b.Usage /usr/lib/zabbix/ex...
- Failed: cannot extract value from json by path "$.model_display": invalid object format, expected opening character '{' or '[' at: '/usr/lib/zabbix/externalscripts/mca-dump-short.sh: Ungültige Option -- b
Usage /usr/lib/zabbix/externalscripts/mca-dump-short.sh -i privateKeyPath -p -u user -v -d tar
Can you help me please?
Thanks
So i try a little bit more.
In the Templates i remove the -b in the mca-dump
mca-dump-short.sh["-d","{HOST.CONN}", "-u", "{$UNIFI_USER}", "-i", "{$UNIFI_SSH_PRIV_KEY_PATH}", "-t", "SWITCH", "-p", "{$UNIFI_SSHPASS_PASSWORD_PATH}", "-U", "{$UNIFI_VERBOSE_SSH}", "-o", "{$UNIFI_CHECK_TIMEOUT}","-b"]
Then it will work on our USW-Pro-48-PoE,.
On our US-16-150W it wont work. Do you know why?
I also solved it by removing the -b from the mca-dump items of the templates but the script to my US-8 still wont work and go in timeout.
Apologies I hadn't committed the correct mac-dump script to the right spot.. Please update and let me know..
It's all working for me. Thank you
For me its working too! Thanks
One question. I added the host with type Agent. But the agent is offline. Is it possible that it is online? Thanks
there's no zabbix agent on switches, so offline is right.. the script is using that connection info though, minus the port.
Good Evening, I am working to get your tools implemented. I am having an issue where Zabbix wont run things correctly. When I run sudo -u zabbix /usr/lib/zabbix/externalscripts/mca-dump-short.sh -d 192.168.0.109 -u admini -i /usr/lib/zabbix/.ssh/zb_id_rsa -t SWITCH
I get the output of the JSON.
When zabbix runs things I get something like this for each host. I am using AP and SWITCH currently. The @@@@ comes when I remove the password path.

Any Help would be appreciated.
Couple of things:
• look in /tmp/mcaDumpShort.err, you should get a more complete error message. The '@@@@..' looks to me like ssh complaining about something
• from the zabbix server, are you able to ssh directly to the switch with that password?
