Web UI stop working! ERR_EMPTY_RESPONSE

[IT_dog]

I have executed all comands as described - still the same situation.

All services related sections doesn't load

[IT_dog]

As for NDOUtils - Message Queue tuning:

I have set first

Code: Select all

# cat /etc/sysctl.conf | grep -v "^#"
kernel.msgmnb = 262144000
kernel.msgmax = 262144000
kernel.msgmni = 512000

kernel.shmmax = 4294967295
kernel.shmall = 268435456

(initial value was twice smaller for msgmnb and msgmax AND wasn't such parameter as msgmni at all so I have added it)

but nothing has been changed after nagios/ndo2db restart

You may be running into https://github.com/maxmind/geoip-api-mo ... /issues/24

Can you PM or attach your /etc/php.ini for review?

[IT_dog]

Has been sent

[dwhitfield]

Did you check that the entire thing got sent? It seems particularly small. Mine is 1659 lines, but yours is 172 lines. If that's not correct, can you use WinSCP or FileZilla to get me the actual file instead of copy/paste?

[IT_dog]

So strange question ...

raw file

Code: Select all

[root@nagiosxi ~]# cat /etc/php.ini | wc -l
1796

excluded newlines and comments starting from ';'

Code: Select all

[root@nagiosxi ~]# cat /etc/php.ini | grep -v '^$\|^\s*\;' | wc -l
172

[dwhitfield]

Ok, I've used the same filter for a valid comparison, and we have a lot of differences. It seems like you have a pretty customized setup, so it might be easiest for me to just give you what you've got and you can see if anything stands out to you. I'm mostly suspicious of your MySQL entries, as all the stuff that's not getting loaded is coming from mysql. The 256 on the memory limit could also be a problem. We often have people raise that as high as 1GB.

There is no results, still the same problem.
But semms that I have some clue.

I can get services list for each host (by clickin on this pictogram):


But I can't do this only over few hosts !
And this are hosts which doesnt load in 'Hostroup Grid' screen!



And the same hosts included in those 'Servicegroup Grid' widgets that doesnt load!

Does it mean something for you?

[IT_dog]

Is there some way to clear db history data for particular services ?
I need to know whats going right now most of time and if history data clearing resolve this problem I'm ready to accept this loss

[tacolover101]

I have tried both of db repair script and full db reinstall cycle (with deleting mariadb and dropping dbs from disk)

This is my problem:

(https://imgur.com/a/JCeDs full post)

are you still seeing the same error in your logs?

i don't think it's your php.ini, but rather a variable that isn't parsing properly.

is spinning up a fresh machine, and doing a backup + restore an option for you? may be cleaner and faster at this point.
