Nagios Support Forum

Hi,

after update from 5.7.2 to 5.7.3 a get same issue as last time.

High CPU consumption on myswld process when applying changes
Changes do not show up untill mysqld is back to normal.

Last time the temporary solution was:
-----------------------------------------------------------------------------------------------------------------------------------

Follow this instructions to downgrade to ndoutils to see if this helps the objects to update quicker..

CODE: SELECT ALL
service nagios stop
cd /tmp
rm -rf /tmp/nagiosxi
wget https://assets.nagios.com/downloads/nag ... .14.tar.gz
tar zxf xi-5.6.14.tar.gz
cd /tmp/nagiosxi
./init.sh
cd /tmp/nagiosxi/subcomponents/ndoutils
./install
chkconfig ndo2db on
service ndo2db start


Then edit your /usr/local/nagios/etc/nagios.cfg and make sure this line is uncommented:

CODE: SELECT ALL
broker_module=/usr/local/nagios/bin/ndomod.o config_file=/usr/local/nagios/etc/ndomod.cfg


Make sure this line is commented:

CODE: SELECT ALL
#broker_module=/usr/local/nagios/bin/ndo.so /usr/local/nagios/etc/ndo.cfg

Then start the nagios service:

CODE: SELECT ALL
service nagios start

Run the Apply Config and see if the statuses and Objects are updated quicker.

Can you confirm i am hitting the same issue? and if so, what will be a definitive solution?

We aware of issues like this in the current release and working to fix it. I would suggest the downgrade again in the meantime.

We've downgrade the ndo and so far the performance seems to be ok.

I hope there will be a fix soon. In the mean time we'll stop patching the system untill fix has released.

Thanks for the update. The change log will be updated to mention a fix for this when it is available.
