Nagios XI Centos OS is down.

[Aruz]

I have out of memory: Kill process 3931 (sendmail ) score1 or sacrifice child Kill process 3932UDI 500, (sendmail) total-vm:80964kb, anon-ress:88kb, file -rss:4kb a lot of erros on the screen

How much RAM do you have? You might need to add more. Otherwise, if you have other products/software running that is taking up a lot of the available memory, that would certainly cause those errors. XI tends to play pretty well on its own as long as you have enough RAM.

I had 2 GB of RAM. I just add 2 more. Now total 4 GB. Starting Nagios up... It is asking root pass.. I do not know. What is default?

[tmcdonald]

If it is our pre-built VM, the default password is nagiosxi

[Aruz]

I think, I got in. I have now
[root@localhost ~]#


What I can do now?

[dwhitfield]

Are you still getting the RAM errors? If not, are you just asking in general what XI can do?

Assuming you still have RAM errors, please answer the following questions.

How many hosts and services do you have? Are the checks active or passive? Did you install anything other than XI on the VM?

What's the output of df -h?

Can you PM me your Profile? You can download it by going to Admin > System Config > System Profile and click the Download Profile button towards the top. If for whatever reason you *cannot* download the profile, please put the output of View System Info (5.3.4+, Show Profile if older) in the thread (that will at least get us some info).

After you PM the profile, please update this thread. Updating this thread is the only way for it to show back up on our dashboard.

My Nagios xi still not working. I am very frustrated. When I type IP address in the browser it saying "This page can't be displayed"
Nagios server has
***An error occurred during the file system check.
***Dropping you to a shell; the system will reboot
***when you leave the shell.
Give root password fro maintenance
(or type Control-D to continue): I did so and it rebooted with the same message.

Please help,
Thank you,
Alex.

***An error occurred during the file system check.

Can you send a screenshot of that error including any preceding text about 20 lines or so?

This appears to be something specific to the machine. It sounds like the machine doesn't have a root partition mounted, or the file system was damaged. It might be more efficient to start with a fresh machine, or if you're fairly familiar with Linux file systems you'll need to verify that the root partition wasn't damaged with a utility like fsck.
