How to calculate NVPS

[sl.unsw]

Hi...

I'm a system admin looking at the backend of a large-ish Zabbix 5.2 deployment. (not sure exactly how big but there's 10,600 rows in the hosts table..)
Before I get to posting about our actual issues - and there's a few since the Zabbix guru who set it up has since left the org - I'd like to know how to calculate the NVPS value for our setup.. my google-fu is failing me on this.

cheers

Found one old(ish) query here.. https://support.zabbix.com/browse/ZBX-7872 Cannot say, if it has changed. But it may give you a direction, where to find it or how its done at all...

just FYI: hosts table also contains templates and proxies, so 10600 is not just hosts. You can arrow it down a bit by "status". Funny name for defining a "type", but ok ... 0 enabled host, 1, disabled host, 3 is template and 6 is proxy. But then again, all of that should be visible on "System information" widget on a dashboard, nvps etc...

Thanks for that! I feel like an idiot now, but in my defense I haven't actually spent much time with the front end, as I'm mainly dealing with the underlying OS and DB issues.. totally hadn't spotted the widget right there staring me in the face!

For the record, it says:

Number of processed character values per second: 9957755
Number of processed log values per second: 360313
Number of processed not supported values per second: 352797042
Number of processed numeric (float) values per second: 12986714030
Number of processed numeric (unsigned) values per second: 12814755557
Number of processed text values per second: 8996504305
Number of processed values per second: 34808287458

..would be quite high values I'm guessing?

I don't like that high number of 'not supported values' perhaps I could start by hunting down what that's all about.

thanks again for the pointer (and the tip about the host table) .. much appreciated.

These are values separated by type, not the NVPS as it is usually.. Seems like acquired with internal item "zabbix[wcache,<cache>,<mode>]". https://www.zabbix.com/documentation...types/internal
You should have a widget that shows you something like his... (I cut off my actual numbers... ) The number you are chasing is the last one here... "Required server performance"... you can always add it to your dashboard, if its not there...

OK, interesting. The System Information widget I have here is a bit different to yours and doesn't show that value, might be a version thing? (We're running 5.0)

hmm... pic is from 4.4 and in 6.0 it is almost the same (has additional HA parameters also) but THAT part is same ...

Well that's interesting. I'm at 5.0.24 so I was going to follow up and post that the NVPS setting should be right where cyber shows it... but my System Information widget isn't displaying it either! We had the NVPS display under previous versions of Zabbix we've run going back years, so I'm afraid to say I didn't even notice that it was missing from the 5.0 widget.

Perhaps it's something the developers experimented with at 5.0, but feedback from users caused it to be reinstated for later versions?

Thanks for confirming that, I'm very glad to know it's not just me!
