User parameter fails when running maven

[tklo]

Hi,

I have a problem with user parameter. I have a git repo in which I have some cucumber tests - I would like to run them using zabbix_agent.

In file /etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf I have three user parameters:

UserParameter=test.sip1, cd /var/lib/zabbix/myapp/ && /labs/apache-maven-3.0.4/bin/mvn -v

UserParameter=test.sip2, cd /tmp/ && /labs/apache-maven-3.0.4/bin/mvn clean install

UserParameter=test.sip3, cd /var/lib/zabbix/myapp/ && /labs/apache-maven-3.0.4/bin/mvn clean install

As a result test.sip1 works correctly displaying the version of maven, test.sip2 works also correctly (it displays build fails since 'maven clean install' is executed in wrong directory), and last key test.sip3 displays ZBX_NOTSUPPORTED. When I execute "cd /var/lib/zabbix/myapp/ && /labs/apache-maven-3.0.4/bin/mvn clean install" as zabbix user manually, then it works correctly.

What could be the problem? Maybe the output of third test.sip3 is too long?

Example how does it look

[root@dt-p-nexus-a1 ~]# zabbix_get -s 127.0.0.1 -k "test.sip1"

ZBX_NOTSUPPORTED

The question is why the third option does not work? I can run the command as a zabbix user manually.

OK, I know what is the problem. I thought that it is a bug and submited it to Zabbix jira here:

https://support.zabbix.com/browse/ZBX-6858?focusedCommentId=85693#comment-85693

And it occured that the problem is of timeout - zabbix agent has a default timeout of 3 sec. I've change it to the max possible timeout which is 30 sec, but still it doesn't help me much, because my "maven clean install" works longer than 30 sec. Anyone has an idea how to work around this problem?
