Public bug reported: It looks like the package (collected-core) is missing a depedency on liboping0. That results in ping plugin not loading:
# /usr/sbin/collectd -tT lt_dlopen ("/usr/lib/collectd/ping.so") failed: file not found. The most common cause for this problem is missing dependencies. Use ldd(1) to check the dependencies of the plugin / shared object. plugin_load: Load plugin "ping" failed with status 1. Found a configuration for the `ping' plugin, but the plugin isn't loaded or didn't register a configuration callback. # ldd /usr/lib/collectd/ping.so linux-vdso.so.1 => (0x00007ffeab82b000) liboping.so.0 => not found libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f52330f3000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f5232d2c000) /lib64/ld-linux-x86-64.so.2 (0x0000559918b50000) after installation of liboping0 # ldd /usr/lib/collectd/ping.so linux-vdso.so.1 => (0x00007ffcfe041000) liboping.so.0 => /usr/lib/x86_64-linux-gnu/liboping.so.0 (0x00007fe45f005000) libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007fe45ecfc000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fe45e935000) /lib64/ld-linux-x86-64.so.2 (0x000055c4dad7f000) details: Description: Ubuntu 16.10 Release: 16.10 # dpkg -l | grep collectd-core ii collectd-core 5.5.2-1 amd64 statistics collection and monitoring daemon (core system) ** Affects: collectd (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1640350 Title: missing depedency liboping0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/collectd/+bug/1640350/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
