How to display network traffic graphs only for business hours?

[andhi.priono]

Hi everyone,
I am looking for a way to filter or display network traffic graphs in Zabbix specifically for business hours. My goal is to see the data only for:

• Days: Monday to Friday
• Time: 07:30 to 16:00

I want to exclude after-hours and weekend data from the visualization to get a clearer view of the network load during work hours.
Is there a built-in way to achieve this in the Zabbix Dashboard? Thanks!

Sorry, update, the settings above worked for me. I also set the timezone between Zabbix and the server. Thank you everyone.

Hello.

It seems that the thread was deleted in the process of eliminating SPAM. The original post appears to have been resurrected, so I would like to offer my opinion again.

If you're happy to arrange five graphs corresponding to the days of the week, such as Monday's graph, Tuesday's graph, Wednesday's graph, etc., it will look like this.
*Assuming the period is from Monday to Friday of last week.

Set the TimePeriod of the graph widget as follows:

Monday
From: now/w-1w+7h+1800
To: now/w-1w-6d-8h+1

Tuesday
From: now/w-1w+7h+1800+1d
To: now/w-1w-6d-8h+1+1d

Wednesday
From: now/w-1w+7h+1800+2d
To: now/w-1w-6d-8h+1+2d

Thursday
From: now/w-1w+7h+1800+3d
To: now/w-1w-6d-8h+1+3d

Friday
From: now/w-1w+7h+1800+4d
To: now/w-1w-6d-8h+1+4d

To change the target week, change the [-1w] entry.

From:now/w = start of this week = Monday 00:00:00
To:now/w = end of this week = Sunday 23:59:59
With this in mind, the rest is simple addition and subtraction.

Trying this...
Monday
From: now/w-1w+7h+18:00
To: now/w-1w-6d-8h+1


I think that 18:00 there should be just "30m" ??

[moooola]

Oops, sorry. I overlooked a mistranslation in Google Translate.
The intended notation is 1800, not 18:00. The goal is to add 1800 seconds.

I will correct my previous post. Thank you for pointing that out.

Yes, create a custom Time Period in Zabbix for Monday–Friday 07:30–16:00 and apply it to your graph or dashboard widget. This will display only business hours and exclude weekends and after-hours.

Where are these created and where are they entered?

Oh no, I mean, I need to calculate traffic during working hours only. So, outside of working hours, traffic is considered zero and is not included in the average calculation. Is it possible?

[moooola]

Oh, so you wanted calculation, not just display.

In that case, integrating with Grafana might be the most straightforward approach. Unfortunately, I don’t have enough hands-on experience with Grafana to explain it properly.

If the requirement is simply “do not collect data outside business hours”, it might be possible by setting the item update interval to 0 and using flexible intervals such as [1-5,07:30-16:00].

However, if the requirement is to “treat values outside business hours as zero”, I can’t think of a clean solution within Zabbix itself. The only workaround that comes to mind would be collecting data externally (e.g. via snmpwalk), post-processing it with a script, and then sending the result to Zabbix — but at that point, it defeats the purpose of using Zabbix.

Sorry, but I’m out of ideas here.

Thank you for your response. Unfortunately, I've tried changing the interval to 0 and using flexible intervals [1-5,07:30-16:00], but no graph was generated.

If you wish to not collect data outside of business hours the flexible interval should be 0 and the time period should be the hours you don't want to collect data, in this case there'll be 3 time periods:

1-5,00:00-07:30
1-5,16:01-24:00
6-7,00:00-24:00

All of them should be set with interval 0, so there'll be no data collection during this time.

This will make your graphs have gaps during this periods of time, not sure if that's what you originally wanted, but you can test it (you can use treat missing data as 0 in your graphs).

P.S. I've tried to make only one flexible interval with all those intervals, but it seems that it isn't supported in item configuration. Anyways, having 3 flexible intervals will work for stopping data collection.

[cyber]

If using scheduled checks (allowing) instead of flexible ones(not allowing), you can get away with 2 lines instead of 3.. 7:30-8 and 8-16:00
But thats personal preference..

you mean like this?



it doesn't work for me
