Recurring scheduled downtime - Alarming visible

[nms]

Hi,

I have two services which i set as a recurring downtime for all weeks, all months. They're set not to be monitored from 17:01pm till 06:59am.
However i could see that an alert was raised at 06:08am (which is between the time frames mentioned) and was visible in the operations center.

My thinking was that a schedule downtime monitor should fire alerts ONLY between those times. Am i missing something?

Attached are screenshot of such settings.

Rgds,

Hi,

The downtime does not mean that you stop to monitor the nodes/services, but that you not send notification/escalation/etc.
You can also calculate Service Availability with or without downtime periods.

If you want to stop the monitoring you have to stop active (and passive) check during your chosen time period.

I kindly ask to Nagios expert to correct me if I'm wrong

Thanks @Francesco!

Scheduled downtime should only alert you after the period is over. Do you receive scheduled downtime starts and end notifications?

Were there any issues with your cron job for recurring downtime?

Can you post the output of this command?

And PM or post these files. Thanks!

Hi,

There were no issues in the cron. Also the log file doesn't produce any errors.
To be clear, what we are after is that if a service has problems it will not be displayed in the operations center (We don't use notifications) if this occurs between those two timeframes. if the problem is still on, then it should be displayed after the period is over.

My doubt was that i had a timeframe from 17:00 pm to 07:59, but the alert on this service was raised at 06:08, being between those timeframes.
Honestly i saw the alarm on the service history of the service, so i cannot fully confirm that it was also visible on the Operations Centre!

Thanks for the information.

What OS and version of XI are you on?

I'm going to try and attempt to test this. I would like to see if come across this, and I'll take a look at the operations center to see if its visible in there.

Have you seen this happen before in the past or just recently?

Hi,

The OS is CentOS 6.9 with the 5.4.12 for XI. It's recent since it was the first time i needed to schedule a recurring downtime for a service.

I tested this out with a few services and have not received any visible alarms during downtime.

Nothing shows up in Operations Center either.

Please continue to review it, and if you see the issue happens again.

Let us know and provide your Nagios XI profile.

Nagios XI Profile Instructions --> On the XI Home Page click "Admin" > "System Profile" --> "Download Profile" button
Save the profile.zip file and upload it here or PM me.
