Hello, i'm monitoring the number of storage objects / the nuked objects (n_object/n_lru_nuked) and the free / busy storage (SMF.s0.g_space/SMF.s0.g_bytes) with mrtg (values from varnishstat) Both graphs indicate a cleared cache at the same time the number of objects drop from about 20 000 to nearly zero the busy storage drops from one GB to about zero bytes (the free stroage goes up from some intermediate value to 100%) -- Kind regards Anton Kornexl Rechenzentrum Universität Passau Innstr. 33 D-94032 Passau Tel.: 0851/509-1812 Fax: 0851/509-1802
