Ubuntu 18.04 / Zabbix 4.4.4
Recently I noticed that one of my discovery scripts (to discover PHP-FPM pools) started acting up where the frontend shows "Cannot create item: invalid value for preprocessing step #1: jsonpath was unexpectedly terminated.".
I have tried removing the data-item (as recommended) but this didn't help either.
Oddly, it does seem to receive data and create items and none are being removed as a result of not being discovered again.
I have checked the JSON and the validator says its valid.
Other discovery scripts work just fine, so it must not like something in the JSON input I am providing?
Steps to reproduce:
- Configure a discovery with:
- Type: Zabbix Agent (active)
- Update Interval: 1m
- No pre-processing settings
- No LLD Macro's
- No Filters
- Ensure the configured item key returns the following JSON output in a discovery:
{
"data" : [
{
"{#PINGPATH}" : "/ping",
"{#POOLNAME}" : "www",
"{#LISTEN}" : "/run/php/php7.3-fpm.sock",
"{#STATUSPATH}" : "/status"
},
{
"{#LISTEN}" : "/etc/php/7.3/tmp/fpm_zabbix_example_com.sock",
"{#STATUSPATH}" : "/status",
"{#POOLNAME}" : "zabbix_example_com",
"{#PINGPATH}" : "/ping"
}
]
}
Result:
- Discovery tab of the host shows an exclamation mark
- Logs show:
