RHEL 7: NDO2DB service is not running

I have Nagios Xi 4.3.2 installed on Red Hat Enterprise Linux 7.3 (Mapio). Recently, I had an issue with my Nagios monitoring tool. It stopped monitoring my devices. When I checked further, I found out that NDO2DB service stopped working. Because of that, I could not see most recent status of any of the devices monitored by Nagios.

I logged on to Read hat box and tried below command to check the status of the service:

#systemctl status ndo2db

You can also use following command to check any service status

#Service ndo2db status

I tried following commands to start/restart ndo2db service.

#systemctl start ndo2db

OR

#systemctl restart ndo2db

After applying above commands, I ran following command again to check status but it failed to start

#systemctl status ndo2db

After doing bit of searching on this issue, I found the solution. I entered following commands to start NDO2DB service.

#service nagios stop
#service ndo2db stop
#rm -f /usr/local/nagios/var/ndo2db.lock /usr/local/nagios/var/ndo.sock
#service ndo2db start
#service nagios start

Once NDO2DB service started, Nagios started to monitor all the devices. I hope you find this article helpful.

Fixed: HTC One M8 USB driver doesn’t recognized by Windows 10

Hi friends, recently I upgraded my Windows 7 OS to Windows 10 on my laptop. Everything was working fine until I plugged my HTC One M8 (Android) phone to laptop using USB cable. A message box appeared stating that it could not detect the USB device. I never had any problem when I was using Windows 7. I used to plug my phone to PC using USB cable and access phone storage as USB drive. I typed my query in google and most of the articles suggested that I should installed HTC Sync Manager and then connect my phone. Well, I installed the required application but it did not resolve the issue. Hence, I removed it. This is my 3 rd HTC phone and I started to find out how I can enable USB debugging mode on my phone. This option is hidden by default. To enable this option, follow these steps:  Go to Settings \ About Select Software Information Click on More  option Now, tap on Build number  option six times in a row. A message will be shown saying “ You are now a developer! ” Go
