No performance graph since update

[Wilfried]

Hello,

I have a problem with performance graphs
Since I updated my server from 2011R1.9 to 2011R2.1 i hve no more datas stored for my graphs
I checked the permission but in the wiki page it is say:

Code: Select all

Check perfdata directory permissions. Nagios XI needs to be able to write to its nagios/share/perdata/ directory. Check the file permissions on that directory and its subdirectories. For example:
ll /usr/local/nagios/share/perfdata
Should return something like this:
drwxrwxrwx 2 nagios nagios 4096 Oct 18 17:01 192.168.5.1

after execute the script firperms
the permissions are apache:nagios

In both case i have no datas stored for graph
service npcd is running

Code: Select all

ll /usr/local/nagios/var/spool/perfdata

result: "total 0"

thanks for your help

Code: Select all

ll /usr/local/nagios/var/spool/perfdata

is just where performance files are before being processed. One processed they are removed.

The data is then stored in a subfolder in /usr/local/nagios/share/perfdata

Also try selecting a timeperiod to view the graphs. There may be some javascript variables that need to be reset after the upgrade. Select the "4 hour view" and see if they show up.

there is no date since mid week 6. when i installed the update
no more data collected since....

Lets start with this:

Code: Select all

chown -R nagios.nagios /usr/local/nagios/share/perfdata
chmod -R 775 /usr/local/nagios/share/perfdata

Were you using rrdcached or a RAM disk at all on your system before the upgrade?

Lets start with this:

Code: Select all

chown -R nagios.nagios /usr/local/nagios/share/perfdata
chmod -R 775 /usr/local/nagios/share/perfdata

Already done but without success

Were you using rrdcached or a RAM disk at all on your system before the upgrade?

I don't think so
how to check rrdcached?

[mguthrie]

rrdcached takes some work to set up, you would know if you had

Can you verify that the npcd service is running ok?

Code: Select all

service npcd restart

Can you watch the following logs and see if you get any errors.

Code: Select all

tail -f /usr/local/nagios/var/perfdata.log

Code: Select all

tail -f /usr/local/nagios/var/npcd.log

Problem solved
i have changed owner for all files in /usr/local/nagios/var
change from "apache" to "nagios"
perfdata.log file was created justed after I've changed the owner: very strange

so thanks a lot for your help

[scottwilkerson]
