At least one option besides ----aaaa is required. OOOOppppttttiiiioooonnnnssss ----aaaa Show statistics for all PUs in the network. If ----aaaa is not given, statistics are printed only for the current PU or for named PUs. Default is to show statistics only for current PU. ----bbbb Print buffer cache statistics. ----eeee Print Ethernet statistics. ----iiii Print I/O processor statistics. ----llll Print load averages. ----mmmm Print memory usage statistics. ----qqqq Print TX queue statistics. ----rrrr Print read-call statistics. ----ssss Print TX semaphore statistics. ----tttt Print transaction statistics. ----wwww Print write-call statistics. OOOOuuuuttttppppuuuutttt FFFFiiiieeeellllddddssss ----bbbb option This option shows the number of RPU local and UPU local and remote buffer cache hits, as well as the number of buffers available and the percentage of memory used by those buffers. ----eeee option For each Ethernet connection on a PU the following statistics are printed. (Four columns are shown for 4-port SIB and two columns for a 2-port SIB. the number of packets sent and received that were either successful or failed; The number of collision errors (more than 15 colli- sions occurred); the number of _n_c_s (no-carrier-sense) packets sent; the number of _l_c_s (lost-clear-to-send) packets sent; the number of _u_d_r (underrun) packets sent; CRC errors, bad alignment (_a_l_n) errors, resource (_r_s_c) errors, and overrun (_o_v_r_n) errors; the number of packets sent after _n collisions (_n = 1,2,3,...,15); the number of buffers active and the low active count for transmit buffers (_t_b); the status of the Ethernet: alive or dead. ----iiii option For each I/O processor on the specified PU, shows the number of channel programs and interrupts. ----llll option Shows the load average for the UPU with disk, real UPU, average RPU, maximum RPU, (all gathered over 1, 5, and 15 minute intervals) the current RPU, and the maximum RPU load since system boot. ----mmmm option For the specified PU, show the size of main memory and the following memory-usage statistics: _m_a_i_n-_m_e_m_o_r_y _s_i_z_e main-memory size in megabytes _f_r_e_e _p_a_g_e_s total free pages of memory, virtual-memory sub- system free, cmem free. (A page is 1024 bytes.) _o_b_j_e_c_t_s memory objects in use by the TX operating sys- tem _f_r_e_e number of free memory objects available _p_a_g_e_s number of pages in cmem pools _c_g_e_t_s TX internal allocation calls (total) _c_f_r_e_e_s TX internal free calls (total) _m_e_m_a_l_l (_c_a_l_l_s, _p_a_g_e_s, _w_a_i_t_s) statistics on memory allocation (TX internal calls, pages allocated, waits for memory) _m_e_m_f_r_e_e (_c_a_l_l_s, _p_a_g_e_s) statistics on memory frees (TX internal calls, pages freed) _d_a_e_m_o_n _w_a_i_t_s number of waits on the RPU for cmem allocation _n_e_w_p_a_g_e_s number of internal cmem-page allocations _p_a_g_e_f_r_e_e_s number of internal cmem-page frees _c_g_e_t _c_a_l_l_s TX internal calls from UPU/RPU _c_g_e_t _c_a_l_l_s _f_a_i_l_e_d number of cget calls that failed due to out- of-memory condition when the caller could not wait, from UPU/RPU _c_f_r_e_e _c_a_l_l_s _o_n _U_P_U/_R_P_U TX internal calls from UPU/RPU heap memory statistics address and size of heap memory, plus number of calls to allocate heap memory, number of calls that failed, the average search length, and the percentage of free heap memory available. ----qqqq option For each PU specified, shows the following statistics for the named TX queue: _i_n_s_e_r_t_s number of calls to _q_u_e_u_e__i_n_s_e_r_t _w_a_i_t_s number of insert calls with no waiting process _m_a_x _d_e_p_t_h maximum value of the queue depth ----rrrr option Show the number of reads, number of local and remote disk reads, and the number of bytes read since the last reboot. ----ssss option For each PU specified, shows the following statistics for the named semaphores: _w_a_i_t_s number of TX internal calls to sem_lock that blocked, on each processor _w_o_u_l_d _w_a_i_t_s number of TX internal calls to sem_lock (on each processor) that did not obtain a lock because blocking was not permitted _s_p_i_n_s number of traverses through lock-contention loops within the TX semaphore code, on each processor ----tttt option Show the number of transaction begins, transaction com- mits, transaction aborts, locks, deadlocks, seconds wait time, and seconds response time since last reboot. ----wwww option Show the number of writes, number of local and remote disk writes and the number of bytes written since the last reboot. SSSSEEEEEEEE AAAALLLLSSSSOOOO User Commands (1): la LLLLIIIIMMMMIIIITTTTAAAATTTTIIIIOOOONNNNSSSS The statistics may overflow. The ----rrrr and ----wwww byte counts are likely to overflow.
