From: Pavel Rochnyack Date: Mon, 10 Oct 2016 07:07:55 +0000 (+0600) Subject: processes plugin: Remove unused fields from structures X-Git-Tag: collectd-5.7.0~51^2~1 X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=14b4024e2e621b440f96e8f2ef1af04d6275ee34;p=collectd.git processes plugin: Remove unused fields from structures Fields cpu_user, cpu_system, vmem_minflt, vmem_majflt are always equal to zero for new entries (which are passed to ps_list_add()). Values of these fields are not used in `procstat_t` entries too. So, that can be safely removed. --- diff --git a/src/processes.c b/src/processes.c index 4e8ca273..8ac05a35 100644 --- a/src/processes.c +++ b/src/processes.c @@ -170,13 +170,9 @@ typedef struct procstat_entry_s unsigned long vmem_code; unsigned long stack_size; - unsigned long vmem_minflt; - unsigned long vmem_majflt; derive_t vmem_minflt_counter; derive_t vmem_majflt_counter; - unsigned long cpu_user; - unsigned long cpu_system; derive_t cpu_user_counter; derive_t cpu_system_counter; @@ -367,24 +363,20 @@ static int ps_list_match (const char *name, const char *cmdline, procstat_t *ps) } /* int ps_list_match */ static void ps_update_counter (_Bool init, derive_t *group_counter, - derive_t *curr_counter, unsigned long *curr_value, - derive_t new_counter, unsigned long new_value) + derive_t *curr_counter, derive_t new_counter) { + unsigned long curr_value; + if (init) - { - *curr_value = new_value; - *curr_counter += new_value; - *group_counter += new_value; return; - } if (new_counter < *curr_counter) - *curr_value = new_counter + (ULONG_MAX - *curr_counter); + curr_value = new_counter + (ULONG_MAX - *curr_counter); else - *curr_value = new_counter - *curr_counter; + curr_value = new_counter - *curr_counter; *curr_counter = new_counter; - *group_counter += *curr_value; + *group_counter += curr_value; } /* add process entry to 'instances' of process 'name' (or refresh it) */ @@ -458,23 +450,23 @@ static void ps_list_add (const char *name, const char *cmdline, procstat_entry_t && (entry->vmem_majflt_counter == 0); ps_update_counter (want_init, &ps->vmem_minflt_counter, - &pse->vmem_minflt_counter, &pse->vmem_minflt, - entry->vmem_minflt_counter, entry->vmem_minflt); + &pse->vmem_minflt_counter, + entry->vmem_minflt_counter); ps_update_counter (want_init, &ps->vmem_majflt_counter, - &pse->vmem_majflt_counter, &pse->vmem_majflt, - entry->vmem_majflt_counter, entry->vmem_majflt); + &pse->vmem_majflt_counter, + entry->vmem_majflt_counter); want_init = (entry->cpu_user_counter == 0) && (entry->cpu_system_counter == 0); ps_update_counter (want_init, &ps->cpu_user_counter, - &pse->cpu_user_counter, &pse->cpu_user, - entry->cpu_user_counter, entry->cpu_user); + &pse->cpu_user_counter, + entry->cpu_user_counter); ps_update_counter (want_init, &ps->cpu_system_counter, - &pse->cpu_system_counter, &pse->cpu_system, - entry->cpu_system_counter, entry->cpu_system); + &pse->cpu_system_counter, + entry->cpu_system_counter); } } @@ -1844,14 +1836,10 @@ static int ps_read (void) pse.vmem_code = ps.vmem_code; pse.stack_size = ps.stack_size; - pse.vmem_minflt = 0; pse.vmem_minflt_counter = ps.vmem_minflt_counter; - pse.vmem_majflt = 0; pse.vmem_majflt_counter = ps.vmem_majflt_counter; - pse.cpu_user = 0; pse.cpu_user_counter = ps.cpu_user_counter; - pse.cpu_system = 0; pse.cpu_system_counter = ps.cpu_system_counter; pse.io_rchar = ps.io_rchar; @@ -1976,13 +1964,9 @@ static int ps_read (void) pse.vmem_data = procs[i].ki_dsize * pagesize; pse.vmem_code = procs[i].ki_tsize * pagesize; pse.stack_size = procs[i].ki_ssize * pagesize; - pse.vmem_minflt = 0; pse.vmem_minflt_counter = procs[i].ki_rusage.ru_minflt; - pse.vmem_majflt = 0; pse.vmem_majflt_counter = procs[i].ki_rusage.ru_majflt; - pse.cpu_user = 0; - pse.cpu_system = 0; pse.cpu_user_counter = 0; pse.cpu_system_counter = 0; /* @@ -2122,13 +2106,9 @@ static int ps_read (void) pse.vmem_code = procs[i].p_vm_tsize * pagesize; pse.stack_size = procs[i].p_vm_ssize * pagesize; pse.vmem_size = pse.stack_size + pse.vmem_code + pse.vmem_data; - pse.vmem_minflt = 0; pse.vmem_minflt_counter = procs[i].p_uru_minflt; - pse.vmem_majflt = 0; pse.vmem_majflt_counter = procs[i].p_uru_majflt; - pse.cpu_user = 0; - pse.cpu_system = 0; pse.cpu_user_counter = procs[i].p_uutime_usec + (1000000lu * procs[i].p_uutime_sec); pse.cpu_system_counter = procs[i].p_ustime_usec + @@ -2260,7 +2240,6 @@ static int ps_read (void) break; } - pse.cpu_user = 0; /* tv_usec is nanosec ??? */ pse.cpu_user_counter = procentry[i].pi_ru.ru_utime.tv_sec * 1000000 + procentry[i].pi_ru.ru_utime.tv_usec / 1000; @@ -2270,9 +2249,7 @@ static int ps_read (void) pse.cpu_system_counter = procentry[i].pi_ru.ru_stime.tv_sec * 1000000 + procentry[i].pi_ru.ru_stime.tv_usec / 1000; - pse.vmem_minflt = 0; pse.vmem_minflt_counter = procentry[i].pi_minflt; - pse.vmem_majflt = 0; pse.vmem_majflt_counter = procentry[i].pi_majflt; pse.vmem_size = procentry[i].pi_tsize + procentry[i].pi_dvm * pagesize; @@ -2370,14 +2347,10 @@ static int ps_read (void) pse.vmem_code = ps.vmem_code; pse.stack_size = ps.stack_size; - pse.vmem_minflt = 0; pse.vmem_minflt_counter = ps.vmem_minflt_counter; - pse.vmem_majflt = 0; pse.vmem_majflt_counter = ps.vmem_majflt_counter; - pse.cpu_user = 0; pse.cpu_user_counter = ps.cpu_user_counter; - pse.cpu_system = 0; pse.cpu_system_counter = ps.cpu_system_counter; pse.io_rchar = ps.io_rchar;
