From: Sebastian Harl Date: Tue, 13 Jan 2009 11:36:01 +0000 (+0100) Subject: processes plugin: Collect VM and stack size stats on Linux. X-Git-Tag: collectd-4.6.0~106 X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=4f05ee0090750ffb0f4915a894b7924566558988;p=collectd.git processes plugin: Collect VM and stack size stats on Linux. On other operating systems those values will currently always be zero since I do not have appropriate test systems available. The new types "ps_stacksize" and "ps_vm" have been added to types.db. --- diff --git a/src/processes.c b/src/processes.c index f4ffef8f..0d670f5b 100644 --- a/src/processes.c +++ b/src/processes.c @@ -118,7 +118,9 @@ typedef struct procstat_entry_s unsigned long num_proc; unsigned long num_lwp; + unsigned long vmem_size; unsigned long vmem_rss; + unsigned long stack_size; unsigned long vmem_minflt; unsigned long vmem_majflt; @@ -143,7 +145,9 @@ typedef struct procstat unsigned long num_proc; unsigned long num_lwp; + unsigned long vmem_size; unsigned long vmem_rss; + unsigned long stack_size; unsigned long vmem_minflt_counter; unsigned long vmem_majflt_counter; @@ -315,13 +319,17 @@ static void ps_list_add (const char *name, const char *cmdline, procstat_entry_t } pse->age = 0; - pse->num_proc = entry->num_proc; - pse->num_lwp = entry->num_lwp; - pse->vmem_rss = entry->vmem_rss; - - ps->num_proc += pse->num_proc; - ps->num_lwp += pse->num_lwp; - ps->vmem_rss += pse->vmem_rss; + pse->num_proc = entry->num_proc; + pse->num_lwp = entry->num_lwp; + pse->vmem_size = entry->vmem_size; + pse->vmem_rss = entry->vmem_rss; + pse->stack_size = entry->stack_size; + + ps->num_proc += pse->num_proc; + ps->num_lwp += pse->num_lwp; + ps->vmem_size += pse->vmem_size; + ps->vmem_rss += pse->vmem_rss; + ps->stack_size += pse->stack_size; if ((entry->vmem_minflt_counter == 0) && (entry->vmem_majflt_counter == 0)) @@ -410,7 +418,9 @@ static void ps_list_reset (void) { ps->num_proc = 0; ps->num_lwp = 0; + ps->vmem_size = 0; ps->vmem_rss = 0; + ps->stack_size = 0; pse_prev = NULL; pse = ps->instances; @@ -562,11 +572,21 @@ static void ps_submit_proc_list (procstat_t *ps) sstrncpy (vl.plugin, "processes", sizeof (vl.plugin)); sstrncpy (vl.plugin_instance, ps->name, sizeof (vl.plugin_instance)); + sstrncpy (vl.type, "ps_vm", sizeof (vl.type)); + vl.values[0].gauge = ps->vmem_size; + vl.values_len = 1; + plugin_dispatch_values (&vl); + sstrncpy (vl.type, "ps_rss", sizeof (vl.type)); vl.values[0].gauge = ps->vmem_rss; vl.values_len = 1; plugin_dispatch_values (&vl); + sstrncpy (vl.type, "ps_stacksize", sizeof (vl.type)); + vl.values[0].gauge = ps->stack_size; + vl.values_len = 1; + plugin_dispatch_values (&vl); + sstrncpy (vl.type, "ps_cputime", sizeof (vl.type)); vl.values[0].counter = ps->cpu_user_counter; vl.values[1].counter = ps->cpu_system_counter; @@ -672,7 +692,9 @@ int ps_read_process (int pid, procstat_t *ps, char *state) long long unsigned cpu_user_counter; long long unsigned cpu_system_counter; + long long unsigned vmem_size; long long unsigned vmem_rss; + long long unsigned stack_size; memset (ps, 0, sizeof (procstat_t)); @@ -739,10 +761,20 @@ int ps_read_process (int pid, procstat_t *ps, char *state) cpu_user_counter = atoll (fields[13]); cpu_system_counter = atoll (fields[14]); - vmem_rss = atoll (fields[23]); + vmem_size = atoll (fields[22]); + vmem_rss = atoll (fields[23]); ps->vmem_minflt_counter = atol (fields[9]); ps->vmem_majflt_counter = atol (fields[11]); - + + { + unsigned long long stack_start = atoll (fields[27]); + unsigned long long stack_ptr = atoll (fields[28]); + + stack_size = (stack_start > stack_ptr) + ? stack_start - stack_ptr + : stack_ptr - stack_start; + } + /* Convert jiffies to useconds */ cpu_user_counter = cpu_user_counter * 1000000 / CONFIG_HZ; cpu_system_counter = cpu_system_counter * 1000000 / CONFIG_HZ; @@ -750,7 +782,9 @@ int ps_read_process (int pid, procstat_t *ps, char *state) ps->cpu_user_counter = (unsigned long) cpu_user_counter; ps->cpu_system_counter = (unsigned long) cpu_system_counter; + ps->vmem_size = (unsigned long) vmem_size; ps->vmem_rss = (unsigned long) vmem_rss; + ps->stack_size = (unsigned long) stack_size; /* success */ return (0); @@ -1198,9 +1232,11 @@ static int ps_read (void) pse.id = pid; pse.age = 0; - pse.num_proc = ps.num_proc; - pse.num_lwp = ps.num_lwp; - pse.vmem_rss = ps.vmem_rss; + pse.num_proc = ps.num_proc; + pse.num_lwp = ps.num_lwp; + pse.vmem_size = ps.vmem_size; + pse.vmem_rss = ps.vmem_rss; + pse.stack_size = ps.stack_size; pse.vmem_minflt = 0; pse.vmem_minflt_counter = ps.vmem_minflt_counter; diff --git a/src/types.db b/src/types.db index 67d8f0d3..17dc76cc 100644 --- a/src/types.db +++ b/src/types.db @@ -80,7 +80,9 @@ ps_count processes:GAUGE:0:1000000, threads:GAUGE:0:1000000 ps_cputime user:COUNTER:0:16000000, syst:COUNTER:0:16000000 ps_pagefaults minflt:COUNTER:0:9223372036854775807, majflt:COUNTER:0:9223372036854775807 ps_rss value:GAUGE:0:9223372036854775807 +ps_stacksize value:GAUGE:0:9223372036854775807 ps_state value:GAUGE:0:65535 +ps_vm value:GAUGE:0:9223372036854775807 queue_length value:GAUGE:0:U serial_octets rx:COUNTER:0:4294967295, tx:COUNTER:0:4294967295 signal_noise value:GAUGE:U:0
