No HOST data graphs

[Fred Kroeger]

Just spun up anbrand new NagiosXI 5 R2.0 VM.
Configured the Host Check to use the check_host_alive command.
This is working fine and looking at the advanced tab, it is returning perfdata OK.

Code: Select all

Status Information:	OK - 10.200.3.3: rta 0.236ms, lost 0%
Performance Data:	rta=0.236ms;3000.000;5000.000;0; pl=0%;80;100;; rtmax=0.413ms;;;; rtmin=0.178ms;;;;

However there are no Graphs for the Host Data - also there no _HOST_ xml/rrd files either for the hosts (which would explain why there are no graphs!)
Service Checks are creating graphs OK for these hosts.

Any ideas ?

regads... Fred

Fred, run the following commands and post the output:

Code: Select all

cat /usr/local/nagios/etc/hosts/<your host>
ll -d /usr/local/nagios/share/perfdata/<your host>
ll /usr/local/nagios/share/perfdata/<your host>

where you substitute <your host> with the actual hostname. Thanks!

Just added another 12 hosts using Bulk Add and none of them are displaying HOST graph details either.
Only the original host "localhost" shows this graph.

I've added hosts today on another Nagios Server, but this was upgraded to XI5 R2.0 and it is displaying the HOST perf data OK

Very strange.

On this host with the issue, can you please increase the logging verbosity and then take a deeper look into the logs. Follow the FAQ entry below to increase the log level of process_perfdata and npcd:

http://support.nagios.com/wiki/index.ph ... leshooting

Wait 15 - 20 minutes and then get a tail of the logs:

tail -250 /usr/local/nagios/var/perfdata.log > /tmp/perfdata.txt
tail -250 /usr/local/nagios/var/npcd.log > /tmp/npcd.txt

Send us a copy of /tmp/perfdata.txt and /tmp/npcd.txt

Don't forget to turn down the log level as per the FAQ when you are done!

[Fred Kroeger]

Onya Troy! You got me looking in the right area - all good now.
The perfdata.log showed that none of the Host checks were being processed. Quick check of /var/nagiosramdisk/host-perfdata showed that the file was slowly growing and not being moved to the /var/nagiosramdisk/spool/xidpe directory.
Problem was a typo in the Command "process-host-perfdata-file-bulk". Fixed the typo and Host perfdata is now being processed and HOST graphs are being updated.

Many thanks Troy - this can be closed now. Regards... Fred

Excellent, great to hear it was something that was easy enough to track down.
