RRD Performance graphs not populating.

Post by danniiffxi »

Hello

I recently moved over to CentOS 7 from CentOS 6 and I have only just noticed that the performance graphs are no longer working. I have tried the usual fixes. for instance if graphs ever stopped on our CentOS 6 this following code used to fix the issue.

Code: Select all

service rrdcached stop
rm -f /usr/local/nagiosxi/rrdcache/*
service rrdcached start
However since moving to CentOS 7 i get this when trying to restart the rrd service.

Code: Select all

[root@nagxi01 nagiosxi]# systemctl restart rrdcached.service
Failed to restart rrdcached.service: Unit not found.
I even checked to see if RRD was installed, which it is.

Code: Select all

[root@nagxi01 nagiosxi]# yum install rrdtool
Loaded plugins: fastestmirror
Determining fastest mirrors
Package matching rrdtool-1.4.8-9.el7.x86_64 already installed. Checking for update.
Nothing to do
Perfdata is still populating, here is an example of what i see in the Advanced tab on GUI

Code: Select all

Performance Data:	'C: free'=1.99717G;2;0.8789;0;29.99039 'C: free %'=7%;7;3;0;100
No files in the rrdcache folder

Code: Select all

[root@nagxi01 rrdcache]# ls -l
total 0
There is file movement in the Perfdata spool folder

Code: Select all

[root@nagxi01 nagiosxi]# ls /usr/local/nagios/var/spool/perfdata/ | wc -l
8
[root@nagxi01 nagiosxi]# ls /usr/local/nagios/var/spool/perfdata/ | wc -l
6
Yet I get nothing on the actual graphs

As you can see from this screenshot, nothing appear to be wrong.

This info may also help.

At risk of solving my own issue, do you advise that I follow this guide? bearing mind that RRD was working jut fine before I migrated from Centos 6 to 7

https://assets.nagios.com/downloads/nag ... ios-XI.pdf

As when i check this part

Code: Select all

Verifying The Setup
The rrdcached configuration options are defined in the /etc/sysconfig/rrdcached file on RHEL,
CentOS, and Oracle Linux systems. On Debian and Ubuntu, they are defined in the
/etc/default/rrdcached file.
I get this reply

Code: Select all

[root@nagxi01 var]# cd /etc/sysconfig/rrdcached
-bash: cd: /etc/sysconfig/rrdcached: No such file or directory
