Discovery Counters, php endpoint using json

[Neil.CrispT]

Hi,

Im using Zabbix for the first time, and have the server installed fine, along with a few other machines with the agent running collecting cpu/mem data etc. However i am wanting to create discovery counters which im currently struggling with.

in the zabbix_agentd.conf file following two lines setup
UserParameter=FailedCounters,php /var/www/html/stats-json.php
UserParameter=FailedCounterNames,php /var/www/html/counter.php $1

excuse the names at the moment, as ive not put much effort in them for now. the first one 'FailedCounters' when used outputs a list of all my failed counters in json format, as example below

{
"data": [
{
"{#COUNTERNAME}": "curlrequest.failed"
},
{
"{#COUNTERNAME}": "gearmanjob.failed"
},
{
"{#COUNTERNAME}": "RequiredXPath.failed"
}
]
}

then the second one, uses the counter name as the argument which is passed in, to return a numeric value eg

893

In the zabbix dashboard under "Discovery", i created the following:
Name: FailedCountersDiscovery
Type: Zabbix agent
Key: FailedCounters

my understanding is that key is used to call the counter in the config file for the agent, UserParameter=FailedCounters.

This appears to be working as i can see under latest data / others a list of counter names for each one that is in the json document example.


I then have an Item Prototypes setup, with the following.

Name: FailedCounterNames $1
Type: Zabbix agent
Key: FailedCounterNames[{#COUNTERNAME}]

after doing some reading i beleive i should be using something more along the lines of.. FailedCounterNames[{#COUNTERNAME}]
