App Install

Measure app installation speed. This scenario has two roles:

  • minimal: Installs a simple app which implements initialisation callbacks but otherwise doesn't contain a lot of code.
  • large: Installs a larger app that contains some dependencies and some generated data as padding to make the bundle larger.

These are intended to catch a compilation slowdown or issues with copying around large WASMs (e.g. accidental cloning or tracing). In each case, the behaviour will uninstall the app it installed so that it can re-install it on the next iteration.

DHT Sync Lag

Measure lag time between an agent publishing data and other peers being able to see it. This scenario has two roles:

  • write: A simple job that just creates entries with a timestamp field. Those entries are linked to a known base hash. For each write, the metric ws.custom.dht_sync_sent_count is incremented.
  • record_lag: A job that repeatedly queries for links from the known base hash. It keeps track of records that it has seen and when a new record is found, and calculates the time difference between the timestamp of the new record and the current time. That time difference is then recorded as a custom metric called wt.custom.dht_sync_lag.

After each behaviour loop the metric ws.custom.dht_sync_recv_count is incremented.

First Call

This scenario installs a simple app which implements the init callback, and measures the time elapsed between start of install and calling init. It will uninstall the app it installed so that it can re-install it on the next iteration. This is required to re-run the initialisation callback.

Full-Arc Create (Validated) / Zero-Arc Read

A full-arc/zero-arc mixed scenario where full-arc nodes create data that gets validated and zero-arc nodes read the data. The scenario has two roles:

  • full: A full-arc conductor that creates entries with a timestamp field. Those entries get validated and then retrieved by zero-arc nodes.
  • zero: A zero-arc conductor that reads the entries created by the full-arc node(s) and records the time lag between when the entry had been created and when it was first discovered.

Local Signals

This scenario is for testing the speed and reliability of local signals. It uses a zome with a function that will emit 10,000 signals. The scenario measures how long it takes to send the signals and how many have been received by the time the zome call ends.

Mixed Arc get_agent_activity

A mixed-arc scenario that measures the DHT's ability to propagate agent activity and make it available via get_agent_activity calls. The scenario has three roles:

  • zero_write: A zero-arc conductor that creates entries on its source chain.
  • full_write: A full-arc conductor that creates entries on its source chain.
  • zero_read: A zero-arc conductor that picks a random writer and repeatedly calls get_agent_activity to observe new entries appearing on the writer's chain, measuring the lag between creation and discovery.

Mixed Arc must_get_agent_activity

A scenario where write agents create entries in batches of 10, while must_get_agent_activity agents each pick a random write agent and repeatedly attempt to create an entry that references the chain top of their latest batch. This reference means that the entry's validation function needs to make a must_get_agent_activity call.

The purpose of this scenario is to measure the time it takes for published agent activity data to be gossiped among authorities and become available to peers that query it via must_get_agent_activity.

This test is similar to Write Validated must_get_agent_activity, but some write agents are zero-arc and all must_get_agent_activity agents are zero-arc. This forces the must_get_agent_activity host call to go to the network.

Validation Receipts

Creates an entry, wait for required validation receipts, then repeat. Records the amount of time it took to accumulate the required number of receipts for all DHT operations. This is measured to the nearest 20ms so that we don't keep the agent too busy checking for receipts.

Each agent in this scenario waits for a certain number of peers to be available or for up to two minutes, whichever happens first, before starting its behaviour.

By default, this scenario will wait for a complete set of validation receipts before committing the next record. If the NO_VALIDATION_COMPLETE environment variable is set, it will instead publish new records on every round, building up an ever-growing list of action hashes to check on.

Write Validated must_get_agent_activity

A scenario where write agents create entries in batches of 10, while must_get_agent_activity agents each pick a random write agent and repeatedly attempt to create an entry that references the chain top of their latest batch. This reference means that the entry's validation function needs to make a must_get_agent_activity call.

The purpose of this scenario is to measure the time it takes for published agent activity data to be gossiped among authorities and become available to peers that query it via must_get_agent_activity.

This test is similar to Mixed-Arc must_get_agent_activity, but all agents are full-arc.

Zero-Arc Create and Read

A zero-arc/full-arc mixed scenario with two types of zero-arc nodes -- ones that create data and ones that read data -- as well as full arc nodes to "relay" the data. The scenario has three roles:

  • zero_write: A zero-arc conductor that just creates entries with a timestamp field. Those entries are linked to a known base hash so that zero_read nodes can retrieve them.
  • zero_read: A zero-arc conductor that reads the entries created by the zero-arc node(s) and records the time lag between when the entry had been created and when it was first discovered.
  • full: A full-arc conductor that is just here to serve entries to zero arc nodes.
