Mass acknowledge or scheduled downtime

[nagios_aws]

Hello everyone,

since I saw it a couple of times, I will explain my problem :

sometimes, I or admin users can't acknowledge problem or Schedule a downtime due to errors (in red in Nagios Web portal).

I don't have the error right now, but is there a way to find it in logs ? what can be the cause of this ?

thank you

You could probably scan through apache2 logs, but these will not tell us much unless it's related to an external resource.

Can you post a screenshot of the error you receive, so we can better help you with the issue at hand?

Hello,

I finally manage to get a screenshot of this, please find it in attachment.

there is absolutely no informations about what went wrong, is it normal ?

Thank you

It's likely we'll need more than 30, but the time you see this, but try

Code: Select all

tail -30 /var/log/messages
tail -30 /var/log/httpd/error_log

If you don't see anything relevant, up it to 100.

Also, what version of XI and the component are you using?

One last question...the screenshot is cut off on the right. I'm assuming there's no pull down menu, links, etc. over on that side?

hello,

I got this problem this morning again, nobody was able to acknowledge problems ...

I check in the "/var/log/httpd/error_log" and here is the result :

I don't know if it's related since it works sometimes without any modifications ...

i'm using 5.2.7 version of Nagios XI,

I have nothing more than what on the screenshot, I attached one more of this morning problem

any ideas ?

[dwhitfield]

Is it the same host or service each time by chance?

What's the output of the following:

Code: Select all

ll /usr/local/nagios/var/rw/
ll /usr/local/nagiosxi/html/includes/components/massacknowledge
sestatus
/etc/hosts

Also, in Admin > System Config > Manage System Config, what are your "Program URL" and "External URL" fields?

I suspect this would happen all the time if this were the case, but do any of your users have spaces in them?

I don't have any space in "username", but I do have some in "Name" field

Any ideas ?

[ssax]

Please run these commands and let me know if it resolves the issue:

Code: Select all

service nagios stop
killall -9 nagios
service ndo2db stop
for i in `ipcs -q | grep nagios |awk '{print $2}'`; do ipcrm -q $i; done
rm -rf /usr/local/nagios/var/rw/*
chown nagios.nagcmd /usr/local/nagios/var/rw
chmod 775 /usr/local/nagios/var/rw
chmod g+s /usr/local/nagios/var/rw
service ndo2db start
service nagios start

Do you use SNMP traps? If so, please send me your /usr/local/bin/snmptraphandling.py.

[ssax]

I added another command in there (the chown one), if you already ran it, please run it again.

Thank you
