Thanks for taking time to reply.
It turns out I did not install php-mysql yet.
After I installed it, the error disappeared.

Thanks again!

I'm trying to install NagiosQL. I downloaded the GitHub tar file and extracted the files to the Apache documentroot. I tried running the installation script from the webpage. The installation script gives an error that MySQL is not installed. I installed the MySQL server community edition from sourc...

I agree that the CPU might be the bottleneck. I tried tweaking some settings, but I now have a different problem. I set the concurrent checks to a number bigger than 1. If I set max concurrent checks to 0 by the way, load increases to 6 or 7 when running `top`. That also sort of confirms the CPU is ...

There are 109 objects in total. On 25 of them the interval is set to 9 minutes. On these objects check_dcm is also set to 9 minutes. There are 85 objects with a check interval of 5 minutes. On 84 of these objects check_dcm is set to 5 minutes. There is one check_dcm file, two services configuring ch...

Thanks for your answers. I appreciate the info. Maybe I'm stuck thinking in terms of command line editing, but just to verify: since all configuration files are stored in an SQL database, how much room does that leave for command line editing/editing configuration files through custom scripts? I'd l...

About 110 hosts, nearly all being monitored with check-host-alive, check_dcm and check_tcp.
If you don't include check-host-alive that's about 220 services in total.

I've been monitoring the traffic generated by the Nagios server using Wireshark. When I look at the output I see spikes every 300 seconds (most checks are se...

If I was in your position, I'd take a look at NagVis. Not only does it give a tool to create your network diagrams straight from Nagios, it also has a container option. As long as you put your network diagram into an php file using basic html, you can create an iframe (container object) in nagvis wh...

Thanks for you response. In my Nagios Core setup I'm using MKLivestatus as backend. Would the installation still be supported if I installed MKlivestatus? according to this thread https://support.nagios.com/forum/viewtopic.php?f=6&t=30570 (@scottwilkerson), it would be no problem to install it. ...

Currently I'm testing Nagios in Nagios Core. As a backend I'm using MKLivestatus. According to system requirements two ways of improving Nagios (XI) performance is through a remote SQL server, and through rrdcache. If I use MKLivestatus while upgrading to Nagios XI would I avoid having to create an ...
