Hi, Something happened and my backups have been failing I'm now at 91% usage on my cluster nodes. /dev/mapper/centos-root 1005G 869G 95G 91% / Failure looks like this: [root@lntnls1 snmp]# curator --loglevel debug snapshot --repository "common" indices --all-indices 2021-04-29 05:51:24,523...

Hi, My AD/LDAP users are no longer able to login to Nagios Log Server since the domain controllers are no longer supporting simple binds. I need to reconfigure the LDAP/AD Integration for TLS, but I am presently unable to add the certificate for the CA. When I step through the "Add Certificate&...

Hi, I'm currently running a couple of Nagios Log Server clusters v2.1.6 running on CentOS 7.6.1810 as originally deployed from the Nagios Log server.ova. These servers are featuring prominently in our vulnerability scans and I should like to upgrade Centos to 8.2, Apache, and PHP. Might you offer an...

We had filled up the disk several months ago. After expanding it seemed to recover without further issue, ...

The instances in one of our two-instance clusters no longer to be in sync. On each instance, cluster status is YELLOW, and the number of active and unassigned shards is equal; # of instances = 1; # of data instances = 1 Likewise, Instance status for each instance shows data for the local instance an...

Thank you for your reply. The Snapshot Repository Considerations doc is a good one, and I've tried following it closely. By doing so, I find I can mount the CIFS share \\hlnas00\nagios on both of the Nagios Log Server instances. Folder ownership now appears to be correct and i was able to create a n...
