How do StatsD and CollectD relate?
Is StatsD and alternative to CollectD
Is StatsD used to aggregate metrics coming from CollectD (and possibly other tools)
something else entirely. If so what?
My CentOS 7 VPS has SELinux enabled and is monitored by Collectd. It uses rrdtool to log the reported data. Pommi released a great solution that made me able to review all data on a webpage called CGP (http://pommi.nethuis.nl/collectd-graph-panel-v0-4/).
The RRD data is stored in /var/lib/collectd/my.host.name
I have installed the newest version of collectd on my CentOS 5.5 machine and since I'm pretty sure it's using SNMPv2, was wondering if I could find a "proxy" for SNMP v3...
I may end up needing to write an SNMP v3 module for collectd.
Collectd has different data source types like Gauge, Derive, Counter and Absolute.
Lets take derive data source type. It basically gives rate of change. i.e (new_value - old_value ) / (new_time - old_time). All I am interested is only in the numerator part. I want to know the (new_value - old_value) without having the time factor in the denominator.
