Edit comments?

Is it possible to edit a comment after it has been posted?

Perhaps there is a file somewhere that the comments are stored, that I can edit with a text editor or database commands?

Thanks.

check_ping insists on DNS

So I'm not sure if this is a bug, or by design... and I don't know enough about system internals to know whose bug/feature it is. I'm running this command: /usr/lib64/nagios/plugins/check_ping -H nessus-lab -w 100,20% -c 500,60% strace tells me that it's following this path: Read /etc/nsswitch.conf,...

Re: Problem with host checks -- host always UP

In your nagios.cfg is use_aggressive_host_checking set to 1? If not return code of 1 will result in an UP state https://assets.nagios.com/downloads/nagioscore/docs/nagioscore/4/en/pluginapi.html Ah. Didn't know that. Indeed, that option is turned off. Thank you very much. I hope I never have to fin...

Re: Problem with host checks -- host always UP

Yes ... and when I run that command, the exit code is 1.

Problem with host checks -- host always UP

I can't figure out what I did wrong. I have my host defined: define host{ use windows-server ; Inherit default values from a template host_name honda ; The name we're giving to this host address ip.add.re.ss check_command ping-with-nc } and I have my command defined define command{ command_name ping...

Circular execution dependency detected

So I'm trying to set up monitoring for MySQL Replication. In short, if one host goes down, the other host shouldn't be surprised that replication has stopped. define servicedependency{ host_name svx service_description MySQL Replication MPS dependent_host_name impreza dependent_service_description M...

Re: parent/child/dependencies and best practices

Thanks for the info. Regarding efficiency, I had read this comment: https://nagios-users.narkive.com/Be06Efk2/parent-vs-host-dependency What I've found is that the host dependency has the following behavior: Nagios goes to check host A Nagios sees host A has a dependency on host B Nagios checks host...

parent/child/dependencies and best practices

Greetings. I have a nagios server named Alpha. It can get to hosts Delta, Echo, and Foxtrot. Delta is a "bastion" host. It can get to hosts Tango, Uniform, and Victor; but Alpha cannot get to those hosts directly. Since Alpha cannot get to Tango/Uniform/Victor, I have checks set up like th...

Re: nagios/nrpe 3.2.0 does not support ECDHE?

Hi, Scott. I'm not sure I understand why this would be a "feature request". This link https://support.nagios.com/forum/viewtopic.php?f=16&t=41448 says things like Nagios and NRPE both depend on the base system encryption tools NRPE is going to use the SSL cert it's configured to use. S...

notice a change in value, not the value itself

Greetings. (I tried searching, but I'm very bad at it.) I was just wondering if anybody had a nagios plugin or script that would alarm, not on the script output itself, but if the script output has changed from what it used to be. My basic thought was "save all of the results from the last hour...
