Memory Usage of by factor 1000

Post by Icarium »

I'm using the memory usage script for linux that came with the cacti package but it displays only a thousandth of the real value even though it uses a multiply by 1024 cdef
i'm new to all this so maybe somebody can give me hint

You talked about using a CDEF, but your statement shows none. So please check your CDEF again

And you're sure to have used this very Graph Template? There are two of them. The one you stated (but it is useful for localhost only) and a ucd/net-snmp memory template, which gives you data for remote hosts as well. If this fits, please send a copy of the CDEF itself as it is shown in the CDEF section just below "Graph Management"
