Gaps in interface's bandwidth graphing

[agpol07]

Hi all,

I face a problem with nagios graphing. Sometimes it stops graphing the interface's bandwidth.
Not just in one specific interface, but all..

[scottwilkerson]

do you see any recent results when running the following:

Code: Select all

grep 'MAX load reached' /usr/local/nagios/var/npcd.log

[agpol07]

These are for September and October

Code: Select all

[agpol07]

Is there something that I can check the time it's happening?

[scottwilkerson]

The threshold can be adjusted by editing /usr/local/nagios/etc/pnp/npcd.cfg

and changing this

Code: Select all

load_threshold = 10.0

to this

Code: Select all

load_threshold = 40.0

Then restart npcd

Code: Select all

service npcd restart

The threshold of 10 can be to low on larger systems and it prevents perfdata from being processed if the system load is above that threshold resulting in gaps

[agpol07]

I changed it but the problem remains.

[scottwilkerson]

When did you have the change, and when do these graphs represent? It would only take place for data after the change.

Also, these look like there are values in the troughs.

[agpol07]

I changed the threshold this morning.
Now the graph is like this..

[scottwilkerson]

It looks like there is data in the troughs, if you hover over the low points is there a value?

[agpol07]

Some have data, some not. But even if they have some data, it's not a normal behavior. There is not such a data traffic drop in my network.
