The Munin Protocols¶
Here we describe the rules for collaboration and communication between Munin’s components.
Introduction¶
Contents on this page will focus on already implemented features. For proposals and ideas look in the Wiki.
Concepts¶
Fetching Data¶
Poller-based monitoring infrastructure
digraph { graph [ rankdir="LR" ]; node [style=filled, fillcolor="white:lightgrey"]; "master" [label="munin\nmaster", fillcolor="white:lightblue"]; "master" -> "node1"; "master" -> "node2"; "master" -> "node3"; }Using the Asynchronous proxy node:
digraph { graph [ rankdir="LR" ]; node [style=filled, fillcolor="white:lightgrey"]; subgraph cluster_munin_node { label = "node1"; "munin-asyncd" -> "munin-node" [label="read"]; "munin-asyncd" -> "spool" [label="write"]; "munin-async" -> "spool"; } "master" [label="munin\nmaster", fillcolor="white:lightblue"]; "master" -> "munin-async" [label="ssh"]; "master" -> "node2"; "master" -> "node3"; }Using SNMP Plugins.
digraph { graph [ rankdir="LR" ]; node [style=filled, fillcolor="white:lightgrey"]; "master" [label="munin\nmaster", fillcolor="white:lightblue"]; "master" -> "node1"; "node1" -> "switch" [label="snmp"]; "node1" -> "router" [label="snmp"]; "node1" -> "access\npoint" [label="snmp"]; "master" -> "node2"; "master" -> "node3"; }
