Database Backend Is Not Running

[tgriep]

Try this to fix it.

Code: Select all

service ndo2db stop
killall -9 ndo2db
rm /usr/local/nagios/var/ndo2db.lock
service ndo2db start
service nagios restart

Then run this and post the output

Code: Select all

 ps -aef |grep ndo2db

[mcwhorts]

ps -aef |grep ndo2db
nagios 2878 1 0 12:14 ? 00:00:00 /usr/local/nagios/bin/ndo2db -c /usr/local/nagios/etc/ndo2db.cfg

and still the DB backend isn't running.

It might take a minute to update the status.
In the XI GUI, can you go to Admin > System Status, under the XI System Component Status dashlet, hover your cursor over the Database Backend status icon, does it show a PID number for ndo2db?

[mcwhorts]

When I hover over it,"ndo2db is not running but subsystem locked" is displayed.

[tgriep]

Strange, ndo2db is running.

Can you run the following and post back the results?

Code: Select all

cat /usr/local/nagios/var/ndo2db.lock
cat /etc/init.d/ndo2db

Lets try and restart everything.

Code: Select all

service nagios stop
killall -9 nagios
service ndo2db stop
service mysqld stop
service crond stop
service mysqld start
service ndo2db start
service nagios start
service crond start

It would be good to see your ndo2db configuration, and to check whether mysql is listening:

Code: Select all

cat /usr/local/nagios/etc/ndo2db.cfg
netstat -na | grep 3306

## TABLE TRIMMING OPTIONS
# Several database tables containing Nagios event data can become quite large

# certain amount of data in them. The options below are used to specify the
# age (in MINUTES) that data should be allowd to remain in various tables
# before it is deleted. Using a value of zero (0) for any value means that
# that particular table should NOT be automatically trimmed.
