Hello guys,
Since 2 weeks, without any change, my nagios is not working 100 % at all.
He start so show "No Matching Services" for some hosts, and after a while is again ok.
Than dont show nothinhg at all, and again, after a while, 100% ok.
i see that nagios core change alone between Running and Not running in seconds..
What can this be ?
Im using Nagios 4.2.2 core at a Ubuntu linux

Configuratios is ok, no errors.
As i wrote, no changes was made at all. After a Reboot from linux, it works again for a while and the problem is comming again.
I dont know what can cause this bahavior, nacios core work stop to work alone, than work again...

First make sure you have a backup of your system, then you would run something like the following
Code: Select all
lvresize /dev/mapper/Nagios--vg-root /dev/sda5
Code: Select all
resize2fs /dev/mapper/Nagios--vg-root
Finally, once these are done verify it has increased

Resizing The Virtual Machine Disk Size doc with different volume labels)
