Wow I am blown away , especially now that I am playing around with expressions and triggers on templates / macros (Thank you for sharing that) , you have such an amazing way of explaining the content thank you once again for a stunning vid , I am currently looking at a nuisance trigger - the CPU trigger is above 75 % for 10 minutes (and the event lasts normally 18 min then stabilizes , but is when the house keeper starts ) and I having little trouble writing the correct expressions , I just need to do a lot more reading and understand what it is that I want to achieve as with your drawing (false positives verses false negatives), Have a great day and thanks again for your content :-) best regards Lance

Say i have a password that expires after 2 days, and i have a query on the server that updates it automatically, and saves it to a file ( via cron). Is there a way to read the file and set the password as a macro? and it keeps getting updated everytim the password changes? This is for an external webhook parameter in "Media Type".

Hi,
For C drive we will get alert for 60 and 20 as well right?

[@deanchild9848]

Thank you been teching myself Zabbix for a while now and your lessons here are excellant. I have been trying this out and came across an issue I want to do Freespace Trigger so if c Drive is less than 1GB set off trigger but this issue I have is what units to put in Macro with % its easy it just % valve but with space it units are B and when I look at lateat data its in MB or GB so When i go to add a valve in {$LOWSPACE}= 1GB or 1024MB or 1073741824B not sure any advise?

[@zabbixtraining]

In bytes. Latest data shoes as mb gb etc because od units used in item. But units are used only for a visualization

Hello, is it possible to set one macro for several FS at once, example: {$MAXSIZE:[/opt|/tmp]} ?

[@zabbixtraining]

No. one value per macro

Please create video to import template for hp3par storage , Ms SQL monitoring and Zimbra email service monitoring in zabbix

[@vanomel528]

By the way it is not so clear for me why on 11:59 macros {$LOWSPACE: "D: "} will return 20? There is no such macros, why your expression will return (you say that) "default value"?

[@zabbixtraining]

because, there is no user macro {$LOWSPACE: "D: "} , and if there is no such value it will use value from user macro {$LOWSPACE}

[@fredruicostamacedo4398]

@@zabbixtraining Hi, don't understand too on my side, the macro should be {$LOWSPACE: "D: "} and not {$LOWSPACE}, so this trigger doesn't work bc it doesn't exists?

I want to create a LLD for windows processes (example: chrome.exe, explorer.exe, etc). How can this be done without manually adding each program?

[@zabbixtraining]

Windows proceses, or services? For a second there is low level discovery rule in official windows monitoring template.

[@PaperTowelSauce]

[@zabbixtraining]

@@PaperTowelSauce It would require to write your own LLD rule, or create items manually.

[@Fractal227]

Can you use macros to find specific services such as Skype?

[@zabbixtraining]

I don't think that that's the case for user macros.

[@vanomel528]

How can I create low level discovery which will create trigger for specific values of discovery elements and will not create it for others?

[@zabbixtraining]

Do you mean simply ignore some discovered entities and don't create triggers for them at all?

[@vanomel528]

@@zabbixtraining yes, ignore some and don't create trigger at all. I assume that I can create always negative expression for trigger, but this is a waste of power. So I have to create lots of similar LLD for this.

[@zabbixtraining]

There is Filter tab in LLD configuration, where u can filter discovered entities by regexp. As example {#FSNAME} matches C:|D:. LLD will process only for matched values. Anything else will be ignored

[@vanomel528]

I know this feature. Ok, I mean what if I want to discover all disks and create trigger only for disk C, but add all the metrics for another disks?

[@zabbixtraining]

There is no native feature for this. I would create two LLD rules. First to create items for everything, second to create triggers with Filter to exclude unwanted ones.

[@reesv01]

Awesome :)

Thank you!
