Data exploration for one metric

[michaelkohn]

Choose a metric from the dashboard and dig into the data.

• What interesting insights did you look into?
• Anything surprise you?
• What additional data did you wish you had?

Tasks refresh

• tasks:refresh
  • (frustrated: 276, tolerated: 40, score 0.09) --- about 96% of the time, it wasn't satisfactory
  • Other data about tasks:
  • tasks:load(frustrated 18, tolerated: 22, score 0.77) --- about 32% of the time, it wasn't satisfactory.
  • enketo:tasks:...:render 5 different forms on render has a score of <= 0.79 while 1 has a score of > 0.79
  • enketo:tasks:...:save 3 different forms on render has a score of <= 0.79 while another 3 has a score of > 0.79

Questions:

• How is this close to reality? How many tasks do people usually accumulate?
• Is this exponential according to the number of reports and contacts?
  • For example, if only 3 tasks but thousands of reports and contacts, does it still take long?

• Other telemetry that can help here

Contact details

• contact_detail:d_community_health_volunteer_area:load
  • (frustrated: 6, tolerated: 31, score 0.64) --- about 61% of the time, it wasn't satisfactory
  • Other data about contact details:
  • While contact_detail:f_client:load (a patient) and contact_detail:e_household:load (a household) are not exceptional, they are tolerable
  • The contact_detail:f_client:load (a patient) loads a card (family planning), tasks and reports.
  • The contact_detail:e_household:load(a household) loads the descendants, tasks, and reports, but it doesn't have contact_summary, which means less processing and maybe that's why it has a bit better score.
  • This is the CHW's home place
  • It has about 47 fields in contact summary
  • It loads and lists all the descendants (households)
  • It loads tasks
  • It loads up to 50 reports from all those households - but is this section useful for them?
  • All this makes the view super long - I mean long scrolls, which means more to "render/paint" at once. The "render/paint" time isn't recorded in telemetry.

Questions:

• What are the values of the granular telemetry for this page?

  • Answered here and here

Boot time

• boot_time
  • (frustrated: 20, tolerated: 15, score 0.71) -- about 36% of the time, it wasn't satisfactory
  • Usually, the first time someone login will require more time because it needs to download everything. And our CHWs had to download around 3000 docs
  • Assuming 17 test users login once in a unique device, then non-satisfactory count [frustrated + tolerated] still outnumber 17 initial logins.

Summary:

• There is no case where there are more telemetry entries greater than 3s than less than 3s
• 2 of 17 users on mobile devices experienced non-satisfactory performance when accessing the CHW Area. They used a low-end phone with Android 5 and Chrome 95 (min-supported versions by CHT).
• From all the steps to load a Contact Detail page (CHW Area), they experienced extreme slowness when loading descendants ( contact_detail:d_community_health_volunteer_area:load:load_children). This was recorded 5 times, and times ranging from 3 seconds to 1.5 minutes.
• 1 of these 2 users experience 10s loading reports (contact_detail:d_community_health_volunteer_area:load:load_reports)

• From all the telemetry related to tasks (excluding task-load and task-reload) the rules-engine:tasks:all-contacts has significant recordings in duration, this telemetry is recorded when fetching tasks for all contacts.
  • Example: The beulah user has a low end phones, in 2 different days this user recorded 15min duration on rules-engine:tasks:all-contacts but only 2 dirty contacts recorded in both days (rules-engine:tasks:dirty-contacts). The slowness doesn't seem to be related to quantity of dirty contacts.

Summary

This research is based on data collected from February 12th to February 17th, 2024. We invited 17 participants, of which 2 had low-end phones (small RAM, Android 5, and Chrome 90). Each had assigned an offline CHW with 3000 to 3800 documents.

This test party was based on the eCHIS Kenya config. Other configs can produce different Apdex scores, therefore highlighting different problems.

Contact details

Our test-party participants accessed three contact details pages: CHW Area, household, and patient. Those with low-end phones experienced poor performance (Apdex: Tolerable and Frustrated), while the others had primarily satisfactory performance.

CHW Area When accessing the CHW Area with approximately 110 households, the two users with low-end phones experienced extreme slowness when loading descendants (households). This was recorded 5 times, ranging from 3 seconds to 1.5 minutes. One user with a low-end phone experiences 10s loading reports for his CHW Area.

Households Eight users experienced non-satisfactory performance when accessing the households (each has 5 to 8 patients). The two users with low-end phones experienced slowness when loading the contact data (household). This was recorded 4 times, ranging from 4 seconds to 11 seconds. The eight users had poor experience when loading descendants (patients). This was recorded 7 times, ranging from 5 seconds to 2.2 minutes. The user taking 2.2min was using a low end phone. Five users had a tolerable experience when loading reports, which was recorded a total of 5 times with a duration of 4s to 7s. Lastly, one user with a low-end phone experienced 1 time duration of 10s when loading tasks.

Patient When accessing a patient page, the two users on a low-end phone experienced slowness when loading contact data. This was recorded 5 times, ranging from 4 seconds to 11 seconds. Similarly, when loading descendants it was recorded 6 times with a duration ranging from 5 seconds to 8 seconds. These two users and one user with a higher-end phone experienced 3 times a duration of 4s when loading reports. While one user with a higher-end phone experienced 1 time (first day of the test party) a duration of 33s when loading tasks.

P.d. CHT can technically support descendants under "patient"; however, for this config, the patient doesn't have descendants. The load descendants process probably didn't return anything for the patient.

Boot time

The test party participants accessed the app using their phones for the first time on February 12th and 13th. During that time, most of the non-satisfactory experiences were observed.

Two users using low-end phones had a tolerable experience during the first code execution (boot_time:1:to_first_code_execution), which was recorded 12 times and had a duration ranging from 4s to 9s.

Next is the bootstrap process (boot_time:2:to_bootstrap); this process is when purging, initial replication, and other executions happen. Eleven users recorded 19 times a duration from 4s to 1.8min; from these, 8 took more than 1min. This is probably related to the first-time access because 12 users registered an initial replication (boot_time:2_1:to_replication) from 4s to 1.7min. From those, 9 took longer than 1min.

P.d. The initial replication was improved significantly last year or so.

Tasks refresh

Tasks refresh was harder to explore just by looking at the data. When visiting the Tasks tab, one process gets the list of tasks, which is recorded differently; the first time the Task tab loads, it records task-load with 3 occurrences of +40s duration. The same process executes again when new data is synced into the phone, a task is submitted, etc. This is recorded as task-refresh; even though it is the same process as task_load, the duration recorded was quite different. There are 26 records of +40s, many of which took several minutes and 2 of which took hours.

The granular telemetry we can use to explore this behavior more is rules-engine:tasks:all-contacts. The rules engine is in charge of getting the list of tasks of all contacts that is eventually displayed on the tasks list page. The beulah user has a low-end phone, in 2 different days, it recorded 15min duration on rules-engine:tasks:all-contacts. This slowness doesn't seem to be related to the number of dirty contacts because only 2 were recorded (rules-engine:tasks: dirty contacts); this is not conclusive yet; we still need to do a deeper investigation on the data associated with these 2 dirty contacts and other processes around the calculation of tasks.

Conclusion

It's unsurprising that low-end phones have a poorer experience due to their low memory, processor, and storage capability. However, I would still have liked to see data from more low-end phone users during this test-party and observe the variation in their data. Keeping higher-end phones in the test activities is fine, we cannot tolerate low performance in hardware with good resources.

For this test-party, we generated a large number of similar tasks, which might not represent reality. I suggest taking production data from 3 different partners and looking at the task-refresh, task-load, and rules-engine:tasks:all-contacts to see if they are indeed having performance times greater than 3s. These three metrics are already being recorded.

Basing only in the test-party data and If I had to pick today some areas to analyze deeper in the code to find performance improvements, I would pick:

• Loading descendants from Contact Details. And as a fallback, the loading of contact data.
• Tasks refresh, the rules engine when getting tasks from all contacts.

The initial replication was greatly improved recently; perhaps some improvements can be made in terms of scoping information to users better so that they download only what they need—like discarding adjacent places that don't provide services.
