Hello,
Working further with puppet, I need to be able to graph both nodes and
class dependencies to be able to diagnose issues and/or redundancies.
Currently, activating graph allows me to get ressources/dependencies
graphs per client.
But I would like to highlight nodes dependenxies as well.
Is there any way to get a global "node-centric" graph ?
If yes, how: server-side, client-side, both ?
For example, my nodes.pp look like:
node N_default{
include C_a;
include C_b;
}
node N_mynode inherits N_default {
include C_c;
}
node N_mynode2 inherits N_mynode1 {
include C_d;
}
node N_mynode3 inherits N_default {
include C_e;
}
Here, I would like to get .dot file as this:
digraph Nodes {
label = "Nodes"
"N_default" [
fontsize = 8,
label = "N_default"
]
"N_mynode" [
fontsize = 8,
label = "N_mynode"
]
"N_mynode2" [
fontsize = 8,
label = "N_mynode2"
]
"N_mynode3" [
fontsize = 8,
label = "N_mynode3"
]
"C_a" [
fontsize = 8,
label = "C_a"
]
"C_b" [
fontsize = 8,
label = "C_b"
]
"C_c" [
fontsize = 8,
label = "C_c"
]
"C_d" [
fontsize = 8,
label = "C_d"
]
"C_e" [
fontsize = 8,
label = "C_e"
]
"N_default" -> "N_mynode" [
fontsize = 8,
color = red
]
"N_mynode" -> "N_mynode2" [
fontsize = 8,
color = red
]
"N_default" -> "N_mynode3" [
fontsize = 8,
color = red
]
"C_a" -> "N_default" [
fontsize = 8,
color = blue
]
"C_b" -> "N_default" [
fontsize = 8,
color = blue
]
"C_c" -> "N_mynode" [
fontsize = 8,
color = blue
]
"C_d" -> "N_mynode2" [
fontsize = 8,
color = blue
]
"C_e" -> "N_mynode3" [
fontsize = 8,
color = blue
]
}

JB

Deep node inheritance hierarchies are likely to cause you pain, largely because nodes sets do not typically admit a single, definitive taxonomy. I recommend at most two levels, including the level of your default node, if any. Your Puppet manifest development will be more productively directed, and as a bonus, with a flat node hierarchy you have little need for a node graph. I observe also that you don''t need dynamic graphing of node dependencies anyway, because all the inheritance tree is declared statically, and does not vary by node. Nevertheless, you should be able to use the resource graph to flag which node declaration(s) are being evaluated: node N_default{ include C_a; include C_b; notify { "node N_default": message => "I am an N_default" } } node N_mynode inherits N_default { include C_c; notify { "node N_mynode": message => "I am an N_mynode" } } This will produce messages in the client logs (possibly useful for debugging), but more importantly, it should introduce top-level, node- type-specific resources into your resource graph.
