Zabbix and Actuator

[tr3pek]

Hi,

I'm trying to monitor a set of java applications which expose some metrics via Spring-Actuator endpoint.



I couldn't find a proper way to handle LinkedHashMap structure in Zabbix, I created a simple JavaScript Preprocessor to get desired value from incoming data:

var msg = value;
msg=msg.replace("{", "");
msg=msg.replace("}", "");

var array=msg.split(", ");
var arrayLength = array.length;
for (var i = 0; i < arrayLength; i++) {
    var element = array[i];
    var label = element.substring(0, element.indexOf("="));
    if(label=="hikari.datasource.threadsAwaiting") {
        return element.substring(element.indexOf("=")+1);
    }
}

That way I could extract only one value (in this case hikari.datasource.threadsAwaiting).
But when I tried to create another Item for retrieving another value from this endpoint (by writing another Preprocessor) I got error saying that JMX Key I used (jmx["org.springframework.boot:type=Endpoint,name=metri csEndpoint","Data"]) is already used.
The same when I tried to create completely new template with such Item. It apperas as if Key has to be globally unique.

My question is:

Is there a way to better handle LinkedHashMap? Or at least some way to create multiple Items with same Key but different Preprocessor to handle different elements?

Hi.
Can you provide example item key for springboot? I'm trying to monitor it through Zorka without success. I always get ZBX_UNSUPPORTED:

zabbix_get -s 127.0.0.1 -p 19256 -k zorka.jmx["java","org.springframework.boot:type=Endpoint,name=metricsEndpoint","Data"]
ZBX_NOTSUPPORTED
zabbix_get -s 127.0.0.1 -p 19256 -k zorka.jmx["java","org.springframework.boot:type=Endpoint,name=Metrics","tomcat.sessions.rejected"]
ZBX_NOTSUPPORTED

kmaslowski zabbix_get is for agent items. jmx stuff is not agent item. It requires Java GW which performs all those queries. And it is server/proxy which turns to JGW, not agent...

cyber I use Zorka (https://zorka.io/) for monitoring java based application servers. Zorka acts as zabbix-agent. It works with zabbix_get, for example:

zabbix_get -s 127.0.0.1 -p 19256 -k 'zorka.jmx["java","java.lang:type=Memory","NonHeapMemoryUsage ","committed"]'
152174592

I can't get data for Springboot Actuator only.
