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>
