[Question #243016]: what does values collected by carbon-cache agent

 

New question #243016 on Graphite:
https://answers.launchpad.net/graphite/+question/243016

I tried to understand what does value like  carbon.agents.[server].metricsReceived means?

All my metrics can be divided in two group
- First group (between 30k-40k metrics) 
 is updated every 5 minutes by my python scripts (pull from graphite server),
- Second group (around 20k metrics)
 is updated by collectd plugin every 5 minutes (push from servers)
 
But when I check various values provided by carbon agent I see some strange values. For example number of metricReceived never falls below 120k. 

carbon.agents.[servername]-a.metricsReceived,1391081580,1391083380,60|120365.0,120317.0,154294.0,120371.0,120336.0,120412.0,120370.0,154266.0,120354.0,120403.0,120275.0,120391.0,154288.0,120375.0,120335.0,120444.0,120277.0,154333.0,120367.0,120355.0,120407.0,120317.0,154205.0,120303.0,120458.0,120370.0,120342.0,154219.0,120400.0,None

Where can I find explanation to those metrics? (If not documentation code is good as well)

I'm looking into I/O issue I have (100% disk usage at dedicated machine) and wonder if my scripts are  fine. Maybe I screwed something in them so they produce more metric they should.
