Hi, 1) Tou have to check if you have objects that are removed from cache because of lack of space. They are marked as "n_lru_nuked" in varnishstat.
2) With your probe configuration, varnish will have to get at least 8 good results out of 10 from probes in order to consider the backend healthy. With an interval of 30s, this can take quite long ;-) Regards, Thierry ----------------------------- De : [email protected] [mailto:[email protected]] De la part de Hernán Marsili Envoyé : mercredi 18 juin 2014 19:15 À : varnish-misc Objet : memory alloc and probe Hi, We have two problems while using Varnish: 1) we actually don't know how to determine if the amount of memory we assigned to the MALLOC is enough or not. varnishstat -1 show this: SMA.s0.c_req 58035 34.08 Allocator requests SMA.s0.c_fail 0 0.00 Allocator failures SMA.s0.c_bytes 4830340101 2836371.17 Bytes allocated SMA.s0.c_freed 2864339421 1681937.42 Bytes freed SMA.s0.g_alloc 44952 . Allocations outstanding SMA.s0.g_bytes 1966000680 . Bytes outstanding SMA.s0.g_space 181482968 . Bytes available SMA.Transient.c_req 72960 42.84 Allocator requests SMA.Transient.c_fail 0 0.00 Allocator failures SMA.Transient.c_bytes 4366160011 2563805.06 Bytes allocated SMA.Transient.c_freed 4365783718 2563584.10 Bytes freed SMA.Transient.g_alloc 350 . Allocations outstanding SMA.Transient.g_bytes 376293 . Bytes outstanding SMA.Transient.g_space 0 . Bytes available 2) PROBE: we configured the probes as follows. What we noticed is, once the backend is mark as sick, even when the service is restored, Varnish continues to answering with a GURU MEDITATION. Is like VARNISH never checks back again the backend to see if it is healthy again. Is that a misconfiguration we have? .probe = { .url = "http://www.tycsports.com/balancer/alive1.html";; .interval = 30s; #chequear cada X seg .timeout = 10s; #timeout de la prueba .window = 10; #el probing funciona como sliding window .threshold = 8; # cuantos del window tienen que estar ok para declararl$ Any help will be much appreciated! tnx :) Regards, Hernán. _______________________________________________ varnish-misc mailing list [email protected] https://www.varnish-cache.org/lists/mailman/listinfo/varnish-misc
