2022-08-26pixelstat: MM metrics: add generic readerRobin Hsu
Add shared functions for reading direct reclaim and compaction duration information. The format is a number of integers. e.g. /sys/kernel/pixel_stat/mm/vmscan/direct_reclaim/visible/latency_stat: 0 0 0 0 0 0 Test: local test Bug: 234564667 Signed-off-by: Robin Hsu <robinhsu@google.com> Change-Id: If09cf4b6538be0bcbb99a9e90a81784a9c406bc9
2022-08-26pixelstat: MM metrics: new vmstat metricsRobin Hsu
We previous employed some vmstat metrics (proc/vmstat). This time we add even more: * Added metrics list "workingset_refault_file" "workingset_refault_anon" "compact_success" "compact_fail" "kswapd_low_wmark_hit_quickly" "kswapd_high_wmark_hit_quickly" "thp_file_alloc" "thp_zero_page_alloc" "thp_split_page" "thp_migration_split" "thp_deferred_split_page" * Note: previous implementation mixed "workingset_refault" and "workingset_refault_file". As old kernel only has "workingset_refault", newer kernel has separated 'workingset_refault_file", and "workingset_refault_anon" This CL define it more clearly, where old metrics are left there for backward compatibility, and added two more metrics for '_file' and '_anon'.

PSI metrics: (proc/pressure/<xyz>, xyz = cpu, io, or memory) sample output: /proc/pressure # cat cpu some avg10=2.93 avg60=3.17 avg300=3.15 total=94628150260 /proc/pressure # cat io some avg10=1.06 avg60=1.15 avg300=1.18 total=37709873805 full avg10=1.06 avg60=1.10 avg300=1.11 total=36592322936 /proc/pressure # cat memory some avg10=0.00 avg60=0.00 avg300=0.00 total=29705314 full avg10=0.00 avg60=0.00 avg300=0.00 total=17234456 avg<n>: <n> = 10, 60, 300 means <n> second moving average stall % 2-decimal digits accuracy. Used fixed-point with 2-decimal digit e.g. 16.66% => 1666 We sample the avg<n> metrics per 5 minutes and aggregate min, max and avg for avg<n> total: total stall (not in percentage) 'total' metrics will not be aggregated. They will be shown as per hour difference (current value - previous value).

2022-08-23pixelstat: MM metrics: framework changeRobin Hsu
Some small change in the MM metrics framework: * Previously preparing atom by a vector "values", and the vector is keep resized per module added in. This CL calculates the last index and allocate space for the vector once for all. Note that later on, if we want to add or remove some metrics, we need to change the last index to keep it sync to the last metric proto file. * Add version for 'PixelMmMetricsPerHour' and 'PixelMmMetricsPerday' (and it is the last metrics as defined in the design doc) Test: n/a Bug: 234564667 Signed-off-by: Robin Hsu <robinhsu@google.com> Change-Id: I35da187f9318e8aed089c3676d8c6df815913f02
2022-08-23pixelstat: MM metrics: keep 1st reportRobin Hsu
For atom 'PixelMmMetricsPerHour', previously we skip the first round metrics reports. The intention was to skip those heavy boot-time metrics so that it won't affect our statistics on normal data. However, in newer implementation, we already have the elapsed_timetsamp_nanos field (event time in "devices time since boot" format) in the Suez table (b/223529199). Now it's even better: We can use the device time to filter out those boot events, and we can separate the statistics into two categories: (1) normal, and (2) boot time. So this time we don't skip the first round report. Test: n/a Bug: 234564667 Signed-off-by: Robin Hsu <robinhsu@google.com> Change-Id: I05705e4b16b6e790b54b17a149179b6ea24f2fdf
