      Description

      I've upgraded to zabbix 3.0 (server and agent)

      I try to use net.tcp.listen to check if a port is listening and I always get 0 as an anwser

      for example.

      on one of the machines I have the following output for netstat -nlpt

      tcp        0      0 0.0.0.0:9234                0.0.0.0:*                   LISTEN      1155/python
      tcp        0      0 0.0.0.0:22                  0.0.0.0:*                   LISTEN      806/sshd
      tcp        0      0 127.0.0.1:25                0.0.0.0:*                   LISTEN      882/master
      tcp        0      0 0.0.0.0:10050               0.0.0.0:*                   LISTEN      18514/zabbix_agentd
      tcp        0      0 :::22                       :::*                        LISTEN      806/sshd
      tcp        0      0 ::1:25                      :::*                        LISTEN      882/master
      tcp        0      0 :::443                      :::*                        LISTEN      1900/docker-proxy
      tcp        0      0 :::8443                     :::*                        LISTEN      1881/docker-proxy
      tcp        0      0 :::10050                    :::*                        LISTEN      18514/zabbix_agentd
      

      this is the output from running zabbix_get on the zabbix server for all available ports.

      [root@zabbix ~]# zabbix_get -s r5.communitake.com -k net.tcp.listen[9234]

          I've just done some more testing
          The issue is with zabbix-agent 3 (zabbix-agent-3.0.0-2.el6.x86_64) on CentOS 6
          On CentOS 7 with the latest zabbix-agent (zabbix-release-3.0-1.el7.noarch) it's working

          What does DebugLevel=4 agent log say when you query these items? What are the contents of /proc/net/tcp and /proc/net/tcp6 (when read by Zabbix user)? Did it work with previous versions of Zabbix agent?

          The latest versions of Zabbix agent have two methods of acquiring this information on Linux: one is to use NETLINK interface and the other is to read /proc files. Could you please run Zabbix agent on that CentOS 6 under strace to see which method it uses (strace zabbix_agentd -t net.tcp.listen[5061])?

          Meanwhile, you might wish to downgrade Zabbix agent to 2.4.

          Tested on both CENTOS 6.7 and CENTOS 7.2 with agent built from sources and on CENTOS 7 - with precompiled agentd. For me net.tcp.listen works just fine.

          While I could not repeat it some testing showed that havig garbage in request.r can result in undetected tcp ports. Plus valgrind complained about unitialized reference.

          Fixed in development branch svn://svn.zabbix.com/branches/dev/ZBX-10431
