Hello @DonForiqua

Thanks for reaching out on this issue, understand that both the web and pdf availability reports are displaying narrow width. I take it that this condition is the same with a different browser? Also is it all graphs or a particular graph with stats that display narrow width?

Let find out from the Apache logs the width and height on the Availability Report:

Code: Select all

grep -Eir 'availability.php' /var/log/httpd/* | less -SR

Looking for on the line:

..........age+Host+Availability&subtitle=All+Hosts&data=42.866%2C48.567%2C8.567&export=0&height=286.467&width=400 HTTP/1.1" 1053

Please let us know the results and other details,
Perry

Hello @DonForiqua

Thanks for sending over the System Profile, 'rrdcached' errors are appearing in the '/var/log/messages' and want to have you verify the status:

Code: Select all

systemctl status rrdcached   #review the status

Also restart the 'npcd.service as well:

Code: Select all

systemctl restart npcd    #review the status

Then watch the '/var/log/messages' to verify if receive further log messages on 'rrdcached'.

Code: Select all

tail -F /var/log/messages

Let's also find out what version 'rrdcached' and 'rddtool'

Code: Select all

rrdcached -h

Code: Select all

rrdtool -h

Please let us the results, on what you find on the given commands, also want to circle back and find out when did this happen and what if any changes to the environment were made?

Thanks,
Perry

The sizing of them is because of how it is written, the cutoffs are because of wkthmltopdf and the way it renders the pages.

There isn't currently a way to change them, we would need to submit a feature request to development to have them change the way it currently works.

For this one:

Code: Select all

vDec 13 08:40:12 napoles rrdcached[3971]: queue_thread_main: rrd_update_r (/usr/local/nagios/share/perfdata/BRI0037_SVRAPLICACIONES/_HOST_.rrd) failed with status -1. (/usr/local/nagios/share/perfdata/BRI0037_SVRAPLICACIONES/_HOST_.rrd: expected 4 data source readings (got 2) from 1639401871)

It's saying that this file expected 4 data sources but only received 2:

Code: Select all

/usr/local/nagios/share/perfdata/BRI0037_SVRAPLICACIONES/_HOST_.rrd

You can rename the file and it should recreate the RRD with the proper number of metrics on it on the next check and start graphing shortly thereafter (about 5 to 15 minutes):

Code: Select all

mv /usr/local/nagios/share/perfdata/BRI0037_SVRAPLICACIONES/_HOST_.rrd /usr/local/nagios/share/perfdata/BRI0037_SVRAPLICACIONES/_HOST_.rrd.old
