I have collectd running the tail plugin and writing data out using the write_graphite plugin (via carbon). This seems to work. If I then change the tail plugin config (e.g. change the Regex or DSType), and restart collectd, graphite stops showing me anything at all.

What this really boils down to is, once I update collectd's config, what do I need to restart/change to make graphite pick up the new data?

  1. Are you sure you're sending data? (Check collectd logs)
  2. Is graphite receiving data? (error, create, update logs in /opt/graphite/storage/logs/carbon-cache)
  3. Is it that the regex in your carbon's is restrictive and doesn't have a rule to accept new schema?

If you could localize the problem, i could assist you by drilling into the specifics.
