Which Document?

kyang · Post by **kyang** » Mon Aug 14, 2017 3:47 pm

@Cristhian_Plaza,

Look at the ndoutils/README starting from line 216 and down.

It lists your error and how to fix it.

https://github.com/NagiosEnterprises/nd ... ter/README

Let me know if this helps

Sorry, here's the document I referred to earlier:

Thanks @kyang!

As of right now, this is what the README says regarding the error (you know in case github is down...and to save you the click!)

If there are insufficient resources for sending messages between the
broker and the daemon, you will see an entry similar to the following
in your logs. (This is logged via the syslog facility, using the level
`LOG_ERR` and the default facility.)

ndo2db: Warning: Retrying message send. This can occur because
you have too few messages allowed or too few total bytes
allowed in message queues. You are currently using 16 of 16
mesages and 65536 of 65536 bytes in the queue. See README for
kernel tuning options.

If you see this entry, the message will likely eventually be sent,
but retrying uses system resources, and there is the possibility that
more messages will queued than can be handled, causing the broker
module to stall.

If you are close to or have exceeded the number of messages, you may
need to increase `kernel.msgmni`. If you are close to or have exceeded
the number of bytes in the queue, you may need to increase
`kernel.msgmnb`. In some cases you may need to increase both.

A conservative approach would be to double the necessary value, stop
and restart both the NDO2DB daemon and Nagios Core, and watch for any
further messages. Note that if NDO2DB is started after Nagios Core,
you may see the warning above as the broker module first attempts to
flush its backlog of messages.

To increase a value, echo the value to `/proc/sys/kernel/msgmni` or
`/proc/sys/kernel/msgmnb` as appropriate.

For example, to increase the number of messages allowed in the queue
to 32, use the command `echo 32 > /proc/sys/kernel/msgmni`.

Once you have determine the correct parameters, you can make them
permanent by editing `/etc/sysctl.conf`. Add or update the line of
the form `kernel.msg{mni|mnb} = <value>` with the value(s) determined
above. The next time the system is booted, the values of the
parameters in `/etc/sysctl.conf` will be loaded.

Yes..., I did all that the document said and is still failing, at first when I configured the msgmnb, msgmax and msgmni values it worked without problem the command systemctl status ndo2db showed me an unique error. The error was about the reading of the PID. after that I wrote this command

Code: Select all

for i in `ipcs -q | grep nagios |awk '{print $2}'`; do ipcrm -q $i; done

I looked the var/log/messages and I am getting this 2 errors

Code: Select all

/var/log/messages:Aug 14 21:18:31 ip-10-0-8-150 journal: Suppressed 995555 messages from /system.slice/ndo2db.service

Code: Select all

/var/log/messages:Aug 14 21:19:01 ip-10-0-8-150 ndo2db: Error: queue recv error.

After I changed the value of /procs/sys/kernel/msgmnb and /procs/sys/kernel/msgmni to 32 and did the same for the sysctl.conf file... I am getting the same error and I don't know what I am doing now

Stepping back to a more basic level. Has this ever worked?

Is mysqld running?

Code: Select all

service mysqld status

Have you verified the credentials match the mysql setup?
any errors in

Code: Select all

tail -200 /var/log/mysqld.log

but I changed some things explained before.

scottwilkerson · Post by **scottwilkerson** » Tue Aug 15, 2017 11:29 am

can you tail the system log on the machine in one terminal and then restart ndo2db in another

Terminal 1

Code: Select all

tail -f /var/log/messages

Terminal 2

Code: Select all

systemctl restart ndo2db

and see if you get the message saying it flushed to datasink.

Also, now that we know you can connect to the database from the CLI, did you verify you have the same credentials in the ndo2db.cfg ?
