 Description   

munin-node config file has

  1. A list of addresses that are allowed to connect. This must be a
  2. regular expression, since Net::Server does not understand CIDR-style
  3. network notation unless the perl module Net::CIDR is installed. You
  4. may repeat the allow line as many times as you'd like

allow ^127\.0\.0\.1$

unlesss "allow" lines are added for foreign host, the mms agent cannot connect. This is not clear from the docs.

additionally, I think configuration of Munin-node may be system/distribution specific and I think generally maintaining configuration instructions for host-operating systems is beyond the scope of the MMS documentation.

From the current documentation:

Ensure that ``munin-node``:

  • is accessible from the system running the agent. ``munin-node`` uses
    port 4949, which needs to be open on the monitored system, so the
    agent can access this data source. Use the following procedure to
    test access: ::

telnet [HOSTNAME] 4949
fetch iostat
fetch iostat_ios
fetch cpu

Replace ``[HOSTNAME]`` with the hostname of the monitored
system. Run these commands from the system where the MMS Agent is
running. If these "``fetch``" commands return data, then
``munin-node`` is running and accessible by MMS agent.

If ``munin-node`` is running but inaccessible, make sure that you have
access granted for the system running the MMS agent and that no
firewalls block the port between ``munin-node`` and the agent. You may
find the ``munin-node`` configuration at
"``/etc/munin-node/munin-node.conf``" or "``/etc/munin-node.conf``",
depending on your distribution.
