Zabbix: Low Level Discovery with Dependent items

Brian van Baekel, Opensource ICT Solutions B.V., Consultant / Zabbix Trainer, The Netherlands talks about Low Level Discovery. LLD is supported already for quite some time, and so are Master and dependent items. Watch the video and learn more about how will things look if we combine those topics and gather metrics in just 1 query? Brian will show a short introduction in how to get this going!

Thank you for your video, this was really useful information and clearly communicated. While not 'exactly' the same, this helped me work out how to achieve a very similar thing using the HTTP agent to pull data and discover objects via an API.

Is it possible to have host prototypes, with items, that depend on the master item on the main host?

1. Failed: cannot extract value from json by path "$.[?(@.fsname=='{#FSNAME]')].bytes.total.first()": no data matches the specified path
I get this error above. This video shows "$.[" but the blog shows "$[" without the dot.

[@simonsonjh]

I see I seriously mis-typed the formula above. I got the test working by substituting "/dev", so the correct one is: $.[?(@.fsname=='/dev')].bytes.total.first() --> $.[?(@.fsname=='{#FSNAME}')].bytes.total.first()

Got it! I used this technique to get the state of services from systemctl. Thanks lots :)

Hoe doe je dit als je meerdere jsonpaden hebt?
