My ramdisk mention was just an aside because it is/was a performance trick. Apologies for the confusion.
I'd ask how many hosts for those 30k checks and guess maybe 30k is too many due to a design issue. What are the 30k checks checking?

Over 2k hosts.

Hi, thanks for the suggestion! In our setup Gearman is definitely required, but not because of the old “ramdisk trick.” The sole reason is the number of checks we must schedule and process. Current architecture One Nagios XI master that hands out roughly 30 000 active service checks every five minut...

Hi everyone, Not 100% sure if this is a Nagios XI or a Nagios Core issue. I’m seeing an odd combination of return-code 255 and full-command echo when a check times out, and the command line contains a clear-text password. I’m running a distributed check setup with Nagios Core 4.5.3 on the master usi...

Hello everyone, I am running Nagios XI 2024R1.4.1 on RHEL 8 and currently using Graphios (Python 2.x) to send performance data to InfluxDB. In my graphios.cfg, I have use_service_desc = True , which causes Graphios to create a separate measurement for each service_description. As a result, we now ha...

I have new information. When I access to a service detail page from Home page of Nagios XI, it begins to load "historytab_content.php" with Initiator "jquery-3.6.0.min.js?1741367335:2 history_tab.png Onece this "process" is finished, submitcommand can be launch as normally. ...

Dear Nagios Team, This week, we upgraded our Nagios XI installation from version 5.8.9 to 2024 R1.4.1. Since the upgrade, we are experiencing high latency when using the "Force an immediate check" action, as shown in the screenshot below: submit_command_time.png If we submit the same comma...

Hi Nagios, We have updated Nagios XI from version 5.8.9 to version 2024R1.4.1. We have noticed that navigation within the Nagios XI interface is much slower. Some actions, such as "Forcing an immediate check," give us the message "The page is not responding." We have another serv...

Hi again, I successfully installed the new nagios-mod-gearman on my Nagios XI server running on RHEL8. These were the steps I followed: First of all, I upgraded Nagios XI, disabling the mod_gearman NEB broker in nagios.cfg. Then, I cleaned up the previous gearmand and mod_gearman installation. sudo ...

Hi Aaron, That's fantastic news, thank you for the update. I'm currently preparing a test server to try the upgrade to the latest version of Nagios XI along with the updated nagios_mod_gearman from the repository you shared. I'll make sure to provide feedback here as soon as I complete the testing. ...

Hi, I have a monitoring infrastructure based on Nagios XI and mod_gearman. Currently, I have one master server running Nagios XI and six worker servers that only have nagios-plugins installed (no Nagios Core or Nagios XI). All checks are distributed using mod_gearman. Due to a security vulnerability...
