<p>This PR https://github.com/collectd/collectd/pull/650 would add naming of sinks to the log, maybe you want to test a self compiled collectd with this patch.</p>

<div>All,</div>
I'm using the write_graphite plugin to write to a graphite cluster. The data I'm concerned with is coming from a central "polling" system that, via SNMP or the Netapp plugin, queries other appliances incapable of running the collectd client. I need this data to reside in a different directory when written based on certain host attributes. On a regular system, I simply add a "Prefix" to write_graphite and that puts the data in the correct place. On a polling machine, that forces the data for the polled system to have the same prefix added, putting it in the wrong directory. <br /><br /></div>
It appears that this should be resolvable via chains, but I'm not having any success. In the write_graphite documentation, the example configuration is described as registering "a writer under this string: write_graphite/example" because of the <br /><br /></div>
<Node "example"><br />...</div>
</Node><br /><br /></div>
configuration. To that end, I've created a write_graphite configuration with multiple nodes and different prefixes:<br /><br /><Plugin write_graphite><br /> <Node "default"><br /> Host "graphite-vip"<br /> Port "2003"<br /> Prefix "core.wl.syseng-test.dev."<br /> SeparateInstances true<br /> </Node><br /> <Node "netapp"><br /> Host "graphite-vip"<br /> Port "2003"<br /> Prefix "core.sh5.storage-netapp.prd."<br /> SeparateInstances true<br /> </Node><br /> <Node "netscaler"><br /> Host "graphite-vip"<br /> Port "2003"<br /> Prefix "core.na.netscaler-lb."<br /> SeparateInstances true<br /> </Node></div>
</Plugin><br /><br /></div>
How can I access these different nodes as separate writers? My chain configuration is complaining that they're invalid following the syntax in the wiki:<br /><br />LoadPlugin "match_regex"<br />LoadPlugin "target_write"<br /><Chain "PreCache"><br /> <Rule "rewrite_netapp"><br /> <Match "regex"><br /> Plugin "netapp"<br /> </Match><br /> <Target "write"><br /> Plugin "write_graphite/netapp"<br /> </Target><br /> Target Stop<br /> </Rule><br /> <Rule "rewrite_netscaler"><br /> <Match "regex"><br /> Plugin "snmp"<br /> </Match><br /> <Match "regex"><br /> Host "^netscaler.*"<br /> </Match><br /> <Target "write"><br /> Plugin "write_graphite/netscaler"<br /> </Target><br /> Target Stop<br /> </Rule><br /><br /> # Default target<br /> <Target "write"><br /> Plugin "write_graphite/default"<br /> </Target><br /></Chain><br /><br />
<div>Question: Is this possible? And if so, what am I doing wrong? Thanks,<br /><br />Mark</div>
