Some host painting other no
Some service painting other no

I do not believe in RAMDISK ...
Slow?
Bad?
What can I do?

Hi,
Some host painting other no
Some service painting other no
It looks like restarting npcd did help, but only for certain hosts and services, let's do a full re-start.

Code: Select all

systemctl stop crond
systemctl stop npcd
systemctl stop nagios
pkill -9 -u nagios
rm -rf /usr/local/nagiosxi/var/dbmaint.lock
rm -rf /usr/local/nagiosxi/var/event_handler.lock
rm -rf /usr/local/nagiosxi/scripts/reconfigure_nagios.lock
systemctl restart mysqld || systemctl restart mariadb
systemctl start nagios
systemctl start npcd
systemctl start crond
systemctl restart httpd
Then run the following command, and let me know if the files are spooling up. Is the system able to keep up processing the performance data?

Code: Select all

watch -n 1 'ls /var/nagiosramdisk/spool/perfdata/ | wc -l'
If so, are the other hosts and services processing performance data? If not, let's check the permission settings:

Code: Select all

ll /usr/local/nagios/libexec/process_perfdata.pl
ll /var/nagiosramdisk
ll /var/nagiosramdisk/spool

Hi,
I am gonna rollback ramdisk
Do you have a guide?
Alright, that can be done. The process of uninstalling the ramdisk is essentially the reverse of the installation. You remove the service file and change the configurations files and commands back to the previous settings. The steps are outlined in the following forum thread:
Remove NagiosRamdisk

Let me know if you're able to successfully remove it.

Re: Perfdata: Nagios not painting performance graphs

Post by FCC_Nagios_Support »

Hi benjaminsmith.

I know what is happening with Perfromance graph. The problem is compatibility with Nagfux. When I stopped Nagflux Nagios started to paint. But when I started Nagfux, Nagios Performance graph stop of painting at the time exactly. When in log we saw trying to delete a file -PID and Perfromance graph log says not found I suposse Nagfux just used yet or deleted yet. Are ther any way to make compatible both products.

Many Thanks
