Unable to get active check working

[rks]

I am running Zabbix 2.4.6 (revision 54796) on a CentOs 6.5 server
and managing a Tomcat 8 instance running on another CentOS 6.5 server.

Managed entity:
Tomcat 8 server
Zabbix agent: Zabbix 2.0.15 (revision 54798)
CentOS 6.5

Zabbix Server:
Zabbix 2.0.15 (revision 54798

My confusion:
Documentation and discussions seem to suggest that active and passive both may not be employed on an agent at one time. Is this true? For some items I need to use active and for others I need to use passive.

My Problem:
I want to check if Tomcat server is running - if not I want to issue an alert.
First, I configured the agent to enable active checks and disable passive checks:

   
    # /etc/zabbix/zabbix_agentd.conf
    #
    Server=

    ListenIP=<agent IP address>

    ##### Active checks related
    ServerActive=manager.xxx.com
    Hostname=tomcat.xxx.com
    
    ## UserParameters to show number of Tomcat Bootstrap processes running
    UserParameter=satellite.server,/opt/jdk/bin/jps -l  | grep -c Bootstrap

I have added the Host "tomcat.xxx.com" on the Zabbix server. And I created
an item of type Zabbix agent (pl see attachment).

After a few minutes (10 minutes) I am monitoring the Latest Data on the host tomcat.xxx.com and I see no data.

I put the agent in debug mode and I do not see it returning the value of the user parameter (satellite.server).

What am I missing?
Also, what is the best way to implement a trigger to be notified when my Tomcat server (tcp/8080) dies or stops?

Thanx,

Are you running 2.0 or 2.4? Your initial description seems in conflict. CentOS 6 has packages for 2.4 so if you are running old software it might be good to upgrade.

I don't have a tomcat server to reference here but I recall it runs as a java process. You could simply use 2 checks to check for the availability of http on port 8080, and also look for the process running your tomcat. Just by way of example:
proc.num[java,,,tomcat.jar] # zabbix agent check
net.tcp.service[http,your-IP-addr-here,8080] # zabbix simple check

Not sure about active checks on that, I mainly use passive

Solved

I figured this out.

My apologies for the conflicting info on my Zabbix server version. I am using 2.4.

I found out by trial and error that I can perform both active and passive checks at the same time.
