Hi ,

I tried to setup users (with monitoring contacts) and trying to give read only access to only few process checks following below link
https://assets.nagios.com/downloads/nag ... ios-XI.pdf

For example -
say user1 mapped to contact1 and contactgroup1 have contact1 .
Mapped contactgroup1 to hosts & services which I need to provide read-only access to user1.
When logged in with user1 in another browser, he can't see any services & hosts that are mapped to.

Note: I have implemented above in couple of other projects which worked like breeze, but for current new project struggling to setup as per requirement.

Tried below points already.
* executed repair scripts (repairmysql.sh and repair_databases.sh)
* tried checking nagios.log - no errors found
* found below errors in /var/log/messages while executing "apply configuration" - not sure if this could be related

Jun 14 15:08:18 mon01 ndo2db: mysql_error: 'Can't find file: 'nagios_contacts' (errno: 2)'

* I have contacts.cfg file without any issues which is listed in the nagios.cfg file as well
* why would nagios complain about "mysql_error: 'Can't find file: 'nagios_contacts' (errno: 2)'"
* Why mysql_error looks for files ? ideally MySQL should complain about tables right ?
* why nagios trying to delete instance id 1 " Error: mysql_query() failed for 'DELETE FROM nagios_contacts WHERE instance_id='1''"

After troubleshooting for 3-4 hours, still couldn't fix the issue , thought of seeking help from forum.
Please help to advise fix for above.
Reading many other posts mostly it will be gone by repair MySQL but in my case this was not fixed.

Hi,

Thanks for posting the error output, it does look like a database issue.

Jun 14 15:08:18 mon01 ndo2db: mysql_error: 'Can't find file: 'nagios_contacts' (errno: 2)'

Let's make sure the nagios_contacts file exists with the proper permissions. Please post the output to the following command.

Code: Select all

ls -la /var/lib/mysql/nagios/nagios_contacts*

Also, please try running the following command to repair the database and let me know if you notice any improvement.

Code: Select all

mysqlcheck -r -f -uroot -pnagiosxi --all-databases

Lastly, please pm the system profile.

Hi,

It's missing the MYI file for that table, however, this should get be regenerated when running a repair on that table. Please run the following commands to try to correct this.

Code: Select all

systemctl start mariadb
echo 'repair table nagios_contacts use_frm;' | mysql -t -u root -pnagiosxi nagios
systemctl restart mariadb

Then check to see if /var/lib/mysql/nagios/nagios_contacts.MYI has been re-created. If so, then try to set up your user accounts once more and let me know if the issue is resolved now.

Code: Select all

ls -la /var/lib/mysql/nagios/nagios_contacts*

If that did correct this issue, it may be necessary to recreate the table from a backup. Let me know if you have recent backups available.

Regards,
Benjamin

Hi Benjamin,
Hope the first command is "systemctl stop mariadb " not "systemctl start mariadb" as the db is already running.

Hi,

If the service is already running, then go ahead and run the repair query and then let me know if the MYI file for the table has been recreated.

Code: Select all

echo 'repair table nagios_contacts use_frm;' | mysql -t -u root -pnagiosxi nagios

Thanks,
Benjamin
