Error: unknown type name 'DBusBasicValue'

[cavaliercoder]

The DBusBasicValue type was introduced to the API somewhere prior to D-Bus v1.6.0.

When trying to build this module on older versions, the following compiler error is encountered:

libzbxsystemd.c: In function 'SYSTEMD_UNIT_DISCOVERY':
libzbxsystemd.c:147:3: error: unknown type name 'DBusBasicValue'

This is apparent when built on CentOS 6 or Ubuntu Precise.

If there is no easy code workaround, then it should be module limitation. Operation workaround can use container. Container with Zabbix systemd module will have D-Bus v1.6.0+ installed and mounted /var/run/dbus/system_bus_socket from the host => container can communicate with host D-Bus API.

You can test it - the latest Docker image monitoringartist/dockbix-agent-xxl-limited:latest includes systemd monitoring module now:

[root@ansiblemaster ~]# cat /etc/centos-release
CentOS release 6.6 (Final)
[root@ansiblemaster ~]# docker run \
>   --name=dockbix-agent-xxl \
>   --net=host \
>   --privileged \
>   -v /:/rootfs \
>   -v /var/run:/var/run \
>   -e "ZA_Server=<ZABBIX SERVER IP/DNS NAME>" \
>   -e "ZA_ServerActive=<ZABBIX SERVER IP/DNS NAME>" \
>   -d monitoringartist/dockbix-agent-xxl-limited:latest
[root@ansiblemaster ~]# zabbix_get -s 127.0.0.1 -k systemd.service.discovery
