Nagios Support Forum

Hi,

We have been always with problems in the pictures of Host Performance graphs. Sometimes, there are some blanks. This happen in the host but not in the ping service graphs.

Also we have monitored many routers, firewalls, and in the Bandwidth graphs there are many information missing. It doesn't draw the pictures corretly. Many blanks here too, the graphs is never continuos, maybe 5 minutes, but then you have 15-20 minutes with no graphs.
I've been investigating to improve the performance in our NagiosXI server with some manuals of Nagios XI as "Using_rrdcached_with_Nagios_XI" "Maximizing_XI_Performance" but we get still the same.

Has anybody get any similar problems, and have knowledge of how to fixed this?

Thank you!

What version of XI are you running?

Could you post a tail of the following logs?

The version is 2011R3.3

The tail of that commands is this:

It looks like you are hitting the max load and timeout settings for performance data processing:

In the file: /usr/local/nagios/etc/pnp/process_perfdata.pl
Change: to: In the file: /usr/local/nagios/etc/pnp/npcd.cfg
Change: to: Restart npcd: Wait 15 minutes after the changes and then recheck the logs and verify if perdata is recorded as expected.

I did that changes and restarted npcd:

npcd_max_threads = 5

# sleep_time - how many seconds should npcd wait between dirscans
#
# sleep_time = 15 (default)

sleep_time = 15


# EXPERIMENTAL

# use_load_threshold - enables/disables load watching
#
# use_load_threshold = <0 / 1> (default: 0)
#

#use_load_threshold = 0


# EXPERIMENTAL

# load_threshold - npcd won't start new threads
# if your system load is over this threshold
#
# load_threshold = <float value> (default: 10.0)
#
# Hint: Do not use "," as decimal delimeter
#

load_threshold = 30.0

But I still get this:

I've just upgraded Nagios to 2012R1.4 and since I've done that, now I don't get any graph regarding bandwidth...

Can you output the results of

ll /usr/local/nagios/var/spool/perfdata|wc -l
3

Are you still seeing new errors in the log?

Yes, still the same:

Just to make sure we rule it out, can you also run these commands and post the output:
