[External scripts] Network error, wait for 15 seconds.

[kbrakel]

Hi all,

I have created some python scripts to perform external checks (on our wi-fi controller) and display the data in zabbix. Everything was working perfectly fine (and for the old scripts it still is) but for my new script I receive this error msg(in /var/log/zabbix/zabbix_server.log):

Zabbix agent item "vszAPI.py["--API_version v8_2 queryClientByWlanName --query uplink --zoneId", "{$ZONEID}"]"  on host "XXX" failed: another network error, wait for 15 seconds

Zabbix will retry 3 times after the network error and then disable the externel check (temporarily).

Does anyone have a clue what could be wrong or if there is more detailed logging info available somewhere? If I manually run the script from the command line (obviously on the same zabbix server/folder) the script returns the expected outcome(a decimal value).

I have some older python scripts that work perfectly fine. These script connect to the same host So the host is actually reachable from the zabbix appliance.

edit: (enabled higher debug level):
