View Full Version : Disk percent item key
Hi,
Got problem with subj.
Key is as follows:
diskused[/var] / disktotal[/var]
However the actual result that I get is
diskused - disktotal.
Any ideas?
Thanks in advance.
Are you using diskused[/var] / disktotal[/var] as a key? It must not work, because you cannot put any expressions in key definition.
An item status having this key will immediately become Unsupported.

While it may indeed be the case that expressions cannot be used inside of item definitions, that would be a very, very cool feature. If they can be used in triggers, why not in items?
That would allow for items like '% of unused disk space'.
Consider the problem of trying to configure a graph of disk space for disks of many different sizes - the best method would be to graph the percentage value.

the first issue i have with that is as follows
imagine me monitoring 400 servers and about 200 cosco devices, as well as 700 printers, and about 350 other thingys. now if i were to set up my monitoring servers (which run nagios, and netdisco as well as zabbix) to do math computation on all servers hard drive space. i would fry my cpu on the spot. monitoring servers should not perfomr calculations, they should have very exact rules. if = 0 or if = 1 now
if my /var slice is greater than 124 Mg full of data then it = 0
if not then it = 1
