Remove NagiosRamdisk

[justine]

Hi,
We have installed Nagios Ramdisk in our NagiosXI server. It seems that this is causing our performance graph to fail.
Do you have procedure on how to uninstall NagiosRamdisk?
Kindly help.

Thanks.

You will have to delete the "/etc/sysconfig/nagios"

Code: Select all

rm -f /etc/sysconfig/nagios

and reboot.

Other than that, you need to revert all of the changes you made. Doing this manually would be:

1. Remove the nagiosramdisk directory:

Code: Select all

rm -rf /var/nagiosramdisk

2. Open /usr/local/nagios/etc/nagios.cfg and change the lines below from this:

Code: Select all

service_perfdata_file=/var/nagiosramdisk/service-perfdata
host_perfdata_file=/var/nagiosramdisk/host-perfdata
check_result_path=/var/nagiosramdisk/spool/checkresults
object_cache_file=/var/nagiosramdisk/objects.cache
status_file=/var/nagiosramdisk/status.dat
temp_path=/var/nagiosramdisk/tmp

to this:

Code: Select all

service_perfdata_file=/usr/local/nagios/var/service-perfdata
host_perfdata_file=/usr/local/nagios/var/host-perfdata
check_result_path=/usr/local/nagios/var/spool/checkresults
object_cache_file=/usr/local/nagios/var/objects.cache
status_file=/usr/local/nagios/var/status.dat
temp_path=/tmp

3. Open the "/usr/local/nrdp/server/config.inc.php" and change this:

Code: Select all

$cfg["check_results_dir"]="/var/nagiosramdisk/spool/checkresults";

to this:

Code: Select all

$cfg["check_results_dir"]="/usr/local/nagios/var/spool/checkresults";

4. Open the "/usr/local/nagiosxi/html/config.inc.php" and change this:

Code: Select all

$cfg['xidpe_dir'] = '/var/nagiosramdisk/spool/xidpe/';
$cfg['perfdata_spool'] = '/var/nagiosramdisk/spool/perfdata/';

to this:

Code: Select all

$cfg['xidpe_dir'] = '/usr/local/nagios/var/spool/xidpe/';
$cfg['perfdata_spool'] = '/usr/local/nagios/var/spool/perfdata/';

5. Open the "/usr/local/nagios/etc/pnp/npcd.cfg" and change this:

Code: Select all

perfdata_spool_dir = /var/nagiosramdisk/spool/perfdata/

to this:

Code: Select all

perfdata_spool_dir = /usr/local/nagios/var/spool/perfdata/

6. Open the "/usr/local/nagiosmobile/include.inc.php" and change this:

Code: Select all

STATUS_FILE = "/var/nagiosramdisk/status.dat";
$OBJECTS_FILE = "/var/nagiosramdisk/objects.cache";

to this:

Code: Select all

$STATUS_FILE  = "/usr/local/nagios/var/status.dat";
$OBJECTS_FILE = "/usr/local/nagios/var/objects.cache";

7. Restart services:

Code: Select all

service nagios restart
service httpd restart
service npcd restart

8. Go to the CCM->Commands, type "perfdata-file-bulk" in the search bar, and hit "Enter".

Modify the "process-host-perfdata-file-bulk" command so that it looks like this:

Code: Select all

/bin/mv /usr/local/nagios/var/host-perfdata /usr/local/nagios/var/spool/xidpe/$TIMET$.perfdata.host

Save.

Modify the "process-service-perfdata-file-bulk" command so that it looks like this:

Code: Select all

/bin/mv /usr/local/nagios/var/service-perfdata /usr/local/nagios/var/spool/xidpe/$TIMET$.perfdata.service

Save. Apply Configuration.

You can check if you were able to make all of the necessary changes by running:

Code: Select all

watch -n 1 "ls /usr/local/nagios/var/spool/xidpe | wc -l"

and

Code: Select all

watch -n 1 "ls /usr/local/nagios/var/spool/perfdata | wc -l"

Wait for a few minutes after running each command, and make sure the numbers are changing to 0 once in a while (the perfdata is being processed).

You can exit the command by pressing Ctrl+c.

Let us know if this helped.
