test-relay
POC for streaming + remote plugins using collectd.
Demo
node1
- collectd
- relay plugin
node2
- Snapteld
- Mock file publisher plugin
Data is collected with collectd on node1, written to the relay plugin and then sent to Snapteld on node2 where it is written to a file by the publisher plugin.
Setup
Use remotey branch of my snap fork and remotey branch of the plugin-lib-go fork. These branches add a POC for support of Plugin Initiated Workflows + service(remote) plugins.
Steps to run:
Install collectd (apt-get install collectd)
Modify the config file
vim /etc/collectd/collectd.conf
Make sure that LoadPlugin write_http is present with the following config:
<Plugin write_http>
<URL "http://<hostname>:9999/metrics">
</URL>
</Plugin>
Enable the other collector plugins in the conf file with what you want to see.
Build snapteld and this plugin. To build this plugin use:
go build -o relay main.go from the root of the repo.
Then: ./relay --service to start as a service on port 8183.
Now start snapteld:
./snapteld -t 0 -l 1
Load Plugins:
snaptel plugin load "http://<hostname>:8183"
snaptel plugin load snap-plugin-publisher-mock-file
-- The example task uses the mock file publisher
Load the task, currently snaptel does extra validation around schedule types so load task via curl:
curl -vX POST localhost:8181/v1/tasks -d @collectd.json --header "Content-Type: application/json"
Watch the results:
tail -f /tmp/collectd.log
