Munin::Node::Client is a client module for munin nodes. This helps simple scripts to talk to munin nodes.
Here all functions are specified, for all functions that return in list context (such as with hashes), the scalar context is undocumented and might get a function in the future.
Connects to a node and returns an Munin::Node::Client object. Currently only support plain connections, ssl and tls are planned. Returns undef if connection fails (and $! probably contains something useful). Returns false if connection is not a munin connection. my $node = Munin::Node::Client->connect(Host => '127.0.0.1:4949');
Returns the last error message. print $node->error();
Returns the node's version my $version = $node->version();
Returns the available hostnames on this 'node' in a list. my @hosts = $node->nodes(); print "$_\n" for(@plugins);
Returns the list of plugins for a host (or default host when left out) my @plugins = $node->list($host); print "$_\n" for(@plugins);
Returns the configuration settings of a plugin as a hash with hasrefs my %config = config($plugin); my $globals = $config{globals}; my $datasrc = $config{datasource}; print $globals{graph_title}; print $datasrc{system}->{label};
Returns the values of a plugin as a hash my %value = fetch($plugin); print $value{system};
quits/disconnects the connection to the node. $node->quit();
