mca-dump-short script issue #96
Comments
|
What kind of AP is it and which fw? |
|
Hi, Like I said, it can return correct/long value sometime, this problem happens to all APs during working time. |
|
does it get any better if you give it a bigger timeout value for -o, say 30? |
Hi, |
|
Actually I just see your comment that it returns the error immediately.. I think this could mean the AP is too busy to collect values and report. Anything interesting on your zabbix server in /tmp/mcaDumpShort.log or .err? |
|
Also, are you on the latest version on the templates? I did put some effort into catching the errors into zabbix and not polluting the logs at least.. |
Oh, I have a big file, mcaDumpShort.err there. File size already >1G. Here is few/newest error info in the file, I think I find the strange line, why did it say "Unable to resolve (http://unifi:8080/inform)"? ================================================= Wed 29 Mar 2023 02:20:36 PM CST AP1 |

Ooh boy I need to make sure it never gets that big.. I’ll do something about that.
On the error in in the json it looks like there might be is a DNS issue on the AP
"last_error_str": "Unable to resolve (http://unifi:8080/inform)",
Is that AP correctly connecting to its controller?
In any case, It looks to me the script is correct in throwing a validation error..

When I found out the template new version, I deleted old one in Zabbix server, and imported it again. I think I can try again.

Hi, I will check how to fix this. :)

Hi,
Thanks for the hard working on this template, it is great one.
I have a Zabbix 6.0LTS environment to monitor Unifi APs, I installed this template without any problem. But the mca-dump-short.sh script sometime will give the error.
Here for examples run this script manually,
$ /usr/lib/zabbix/externalscripts/mca-dump-short.sh -d AP_address -u admin -i /home/zabbix/.ssh/zabbix/ -t AP -o 15
{ "at":"14:24:59", "r":"validationError: .vap_table? != null and .radio_table != null and ( .radio_table | map(select(.athstats.cu_total>0)) | length>0 ) ", "device":"AP_address", "mcaDumpError":"Error" }
sometime, it returns the error immediately, sometime it returns the correct long values.
I checked Zabbix server log, there are lot error to all APs.

Please advice, where is the problem.
