Hello @deek,

Prior to this error, did you have any other issues with the server? A couple more questions to help us troubleshoot the issue.

1. What version of Fusion are you running?

2. Can you post the logs for the database and system messages?

Code: Select all

tail -50 /var/log/mariadb/mariadb.log
tail -50/var/log/httpd/*access_log
tail -50 /var/log/messages

3. Verify the server has enough disk space (post output).

Code: Select all

df -h

4. Increase the Polling Subsystem Memory

Hi Benjamin,

Usually the nagios fusion used to be very slow nothing more than that.

1) Nagios fusion version : 4.1.5
2) Uploaded the required logs ( nagios_fusion_logs)
3)Uploaded the df -h pic ( nagios_fusion_df_h)
4) Not able to tune it since the nagios fusion console is not accesible.

Thanks
Deepan.

Hello Deek,

The server is running out of free RAM and therefore is not enough memory available for the database.

InnoDB: mmap(137756672 bytes) failed; errno 12
200117 1:38:19 InnoDB: Completed initialization of buffer pool
200117 1:38:19 InnoDB: Fatal error: cannot allocate memory for the buffer pool

Is this a VM or physical server? Would you be able to add more RAM to this server and then re-start the server?

[deek]

It’s a VM

Hi,

Ok. Thanks. Can you increase the memory, restart and let me know if the issue is resolved?

[deek]

Thanks Benjamin. We will validate after the RAM changes and update here.

Hi Deek,

Thanks Benjamin. We will validate after the RAM changes and update here.

Sounds good. Also, the current version of Fusion is 4.1.8 and there were some important performance improvements in this release. If possible, I would highly recommend updating to the latest version.

See: Nagios Fusion Upgrade Instructions

Backup before making any changes or updates.

Sure Benjamin.
