hi, i have installed almalinux on virtualbox.received this error message "could not determine OS.please make sure lsb_release is installed or your OS info is in /etc/os-release." was tried install lsb_release as command sudo yum install redhat-lsb-core but still error.any idea how to rectify on this?
Hi @danismy1435 - Thank you for your comment. We currently do not support installing Nagios XI on Alma Linux. For a list of supported operating system versions, please check out ➡️ nagiosenterprises.my.site.com/support/s/article/Nagios-Software-OS-supported-versions . Hope this helps!
@@nagiosvideo Hello, might be a more advanced question and I should take this to the forum, but just in case you know... What if I want to install a second (High availability server) of Nagios, not active until the main one goes down or something. Is it ok to move a backup, and will that cause any issues with the license? (as far as I know, a license has 3 uses, Prod, UAT and HA), will the same license work? Thanks in advace.
Great question. The third license is disaster recovery (DR), rather than high availability (HA). It may seem like splitting hairs, but there is an important difference. DR typically refers to a more manual restore process, whereas with HA you're typically back up and running before people realize what's happened. You could do a nightly restore of your production backup to DR, but turn off the monitoring engine in DR when you're done. That way, if production were to go down, you could simply turn on the engine in DR and be back to monitoring like normal. The upside is you don't have to wait for a restore of the latest backup to DR to get monitoring again. The downside is that DR could have been monitoring your production Nagios XI instance. If you were to do a nightly restore of the backup and turn off the monitoring engine, your DR instance would not be able to monitor the prod Nagios XI instance. While this gets you much closer to HA than the typical DR setup, if you're not working in Nagios' web interface regularly, you might not notice if prod Nagios XI has crashed. In such a scenario, you might accidentally increase the time to restore monitoring. Hope this helps!

Hi Team, Thanks for both sessions. This video resolved my doubts. Please continue with that kind of content video. Again Thank you Nagios. Regards, Bhavesh Kumar
Hi there! You have a couple of options: 1) You can use the CCM as the error message advises. The CCM will then guide you in discovering what other concerns need to be handled. 2) If you are determined to use the API, you will need to remove all dependencies, parent-child relationships, and services from the host before removing the host.
I'm really looking forward to seeing what AI/ML brings to log monitoring. I'd like to ask a NLM a question like "Last night this application ran slower than normal, what was different last night than the nights it ran normally?" I can see it getting used as a diagnostics tool. I know what I want to get, but It's not always easy to match up the logs and other metrics on a system you're not completely familiar with. This could be a real game changer.
Weird guy - tell me why I cant apply a command on all members of a host group? Also, I would like my host group to be dynamic, formed automatically by AWS tags. Nagios is such a relic. Make it AWS friendly .. publish the access policy it needs to function... and make the aws access key optional, because we can also use instance roles to run aws commands from nagios machine without needing aws key. relic, relic, relic
Thank you for your question, @dstgre! I think what you're looking for is the method we call Host Group Inheritance. This method of setting up your monitoring environment has you configure your service checks so that they are applied to one or more host groups, rather than a specific host. Then, whatever hosts are assigned to the host group will get the service check. You can couple this with custom macros at the host level and/or in a host template. For example, if you have a bunch of systems running the Nagios Cross-Platform Agent (NCPA), each host could have a unique NCPA token defined in a custom host macro. Your host config would have _ncpa_token = SuperSeekritToken. Then, your host group inherited service check would reference that whenever making an NCPA service check by calling $_HOSTNCPA_TOKEN$. This helps keep your inventory dynamic and extremely fast to set up. You can absolutely integrate with AWS if you like. With Nagios XI, you have access to an API where you can add/remove/modify hosts and services, among other tasks. So, let's say you have a script that reaches out to spin up a new server in AWS. Instead of affecting just AWS's API, it could also reach out to Nagios XI's API and create the base monitoring setup for that new server. Since you're deploying much of your monitoring through host group inheritance, you can be certain that your servers are getting a good, standardized set of monitoring in place as soon as they're spun up in AWS. Hope this helps! Thank you for being part of the Nagios community. xoxoxoxo Weird Guy
Great question. If you clone the repository for an offline install, then the offline install process will cover basic Apache + database installation. You shouldn't need to do anything extra. Happy Monitoring!
I have installed the Nagios 4.4.14 version how to configure the network The following error is occurring. It appears as though you do not have permission to view information for any of the hosts you requested... If you believe this is an error, check the HTTP server authentication requirements for accessing this CGI and check the authorization options in your CGI configuration file.
Hello, thank you for your comment! This video is referencing our commercial solution, Nagios XI. It would appear you are using our open source tool, Nagios Core. You can find documentation on how to configure items in your network here: assets.nagios.com/downloads/nagioscore/docs/nagioscore/4/en/toc.html We also have a community forum where you can troubleshoot with our online community: support.nagios.com/forum/ If you are interested in saving some time, Nagios XI has all the abilities of Nagios Core but with a much easier experience: www.nagios.com/downloads/nagios-xi/
Great video!. Just curious.. say I'm monitoring a network device, is it possible to modify the host email notification so that it includes a list of the services on the host?
Hi @smulungi, notifications are tied to the user, rather than the host or service. You can modify an email notification to include the total number of services associated with the host, the total number of ok/warning/critical. But not a list of services associated with the host. Here is a list of the macros that you can use to customize notifications. assets.nagios.com/downloads/nagioscore/docs/nagioscore/4/en/macrolist.html . Happy monitoring!
Thanks for the explanation!! On an unrelated note, there’s a channel on RU-vid called ‘ETA Prime’ that mostly dabbles in single board devices like Raspberry Pi. You sound JUST like that guy. Your voices are eerily similar. Anyway, thanks again!! >M<
For the best possible assistance on this matter, please ask our professional, in-house technicians on the Nagios Support forum. If you have not already registered for the Forum, this video shows you how ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-8OcOuP9OtI4.html
Basically, a MIB is a file that details out information about different OIDS but can be easily compared to a DNS where domain names (words) are converted into IP addresses.
I am a servicenow developer, in servicenow we have service mapping which is using OID and MIB concept, after watching this video it is very simple for me to understand it
