Hi,

We are currently receiving errors in the system status -
- Performance Grapher
- Database Backend

No performance graphs being written
I have attempted to restart both services and npcd.
Have turned up logging levels, however still nothing new being written.
npcd service is running
Number of spooled files in /usr/local/nagios/var/spool/perfdata/ is increasing (approx 900)

Any assistance would be appreciated. Happy to provide any information.

Based on the log you showed I believe you are hitting the load threshold.

One of the top problem causes to look for in the above log is lines indicating that you are hitting a load threshold, this is common if you are either receiving too much data for NPCD to keep up with the current system's load, or that it is trying to crunch through stacked up performance data.

You can increase this threshold by editing the following file:

/usr/local/nagios/etc/pnp/npcd.cfg

Change:

Code: Select all

load_threshold = 10.0

To a value greater than your system's current load. Use this with caution however, as the NPCD process will eat as much load as you give it, so watch your resources!
