Dear Alan, To show my module statistics using radmin I referred command.c and radmin.c and added my new command "show module statistics <module>". To brief you, I added an usigned array of module return codes in module_instance_t structure and updated the array in call_modsingle() function using the statement: modsingle *sp; sp->modinst->rtcode[result] = sp->modinst->rtcode[result] + 1; I tested this and it is giving 100% correct results. Now I have written a function static int command_show_module_statistics(rad_listen_t *listener, int argc, char *argv[]) in command.c file. I have used radius methods & structures only in this function, so guide me which is correct/wrong or what else radius methods or structures should be used. The problem is that correct module statistics are not being diplayed rather it is displaying 0 statistics for all modules.Please help me resolve this. Here goes the function code: static int command_show_module_statistics(rad_listen_t *listener, int argc, char *argv[]) { int i; CONF_SECTION *cs; module_instance_t const *mi; if (argc != 1) { cprintf(listener, "ERROR: No module name was given\n"); return 0; } cs = cf_section_find("modules"); if (!cs) return 0; mi = find_module_instance(cs, argv[0], false); if (!mi) { cprintf(listener, "ERROR: No such module \"%s\"\n", argv[0]); return 0; } for (i = 0; i < RLM_MODULE_NUMCODES; i++) { cprintf(listener, "\nRTCODE[%d]=%ld\n",i,mi->rtcode[i]); } return 1; /* success */ } Regards, Sonu
