[Pnp4nagios-users] pnp_gearman_worker, rrdcached, and RRD_STORAGE_TYPE

[Amin A. <ami...@ac...>]

Hello-

I have a pnp4nagios 0.6.11 setup using rrdcached and mod_gearman. I have
configured RRD_STORAGE_TYPE to SINGLE since the rrd files that I am copying
from the nagios server I am migrating from were a single rrd per service.

When I moved the rrds into place and restarted pnp_gearman_worker and the
nagios service, I noticed that that I wasn't able to view the historical
data. When I compared the source perfdata directories to the perfdata
directories that were copied into place in my new pnp4nagios setup, I saw
something curious. In the source directory I have a file called
CPU_Stats.rrd. In the new directory I have that file plus the following:

CPU_Stats_CpuIdle.rrd  CPU_Stats_CpuIowait.rrd  CPU_Stats_CpuNice.rrd
 CPU_Stats_CpuSteal.rrd  CPU_Stats_CpuSystem.rrd  CPU_Stats_CpuUser.rrd

Why would I get multiple rrd files per service though I have configured
process_perfdata.cfg to the contrary?

I appreciate your time.
