I am new to nagios and we have a small issue I need to ask assistance with. Many of the machines that we monitor can go unresponsive for a bit when some very intensive cpu tasks are run.
I have configured Nagios 3.4.4 on CentOS 6.3 Final. I have also configured Postfix with SMTP email server. I have verified from console that I am able to send email notifications and recieved them on designated address.
Nagios is configured to send notify-host-by-email and notify-service-by-email.
With Nagios, the leading open source infrastructure monitoring application, you can monitor your whole enterprise by using a distributed monitoring scheme in which local slave instances of Nagios perform monitoring tasks and report the results back to a single master. You manage all configuration, notification, and reporting from the master, while the slaves do all the work.
Hi,
Is it possible to chain multiple nagios servers together, or is there a tool that's available that can notify me when a nagios server is no longer reachable?
The idea here is that if the nagios server itself goes down, I won't know if the hosts it's monitoring are no longer available.
I'm pretty sure this capability exists within nagios, but I've searched and must not be searching cor
I have Nagios running on a webserver. For this one Nagios service check in particular, if it fails, it will run a script.
We have a setup where there are distributed Nagios running on multiple sites and are equalizing their data to the main Nagios server. The problem is it sends back the data to main Nagios server no matter if there is a state change in host or service. Is it possible to configure the slave Nagios to check the service/Host every 5 sec but send back the data only if there is a state change.
I have a Nagios machine which monitors many linux\windows servers.
I started working here about a week ago and got a task to make order in the Nagios.
As part of my order i had to add 2 more linux servers to the Nagios.
I've installed nagios-plugins and nrpe on both machines, in addition, i've verified that port 5666 is opened and listening on both servers and i can see nrpe running in ps -aux |gr
Recently i am not getting any email notification in nagios, i have tested it by sending emails manually from root user and nagios user and i have got the mail sucessfully. But i am not any email alerts in case any issue, so that i tested it by sending custom host notification from WEBUI, something seems to be wrong in the log.
I monitor all my servers using Nagios. Now, for Nagios to run certain checks, it has to connect to remote hosts via a certain port. Lets say the port is 8090.
Now, when Nagios connects to a remote host (for an example) via port 8090, and it has to run 6 checks (scripts) on that remote host, i find that it times out.
