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.

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.

Write/get_agent_activity

A scenario where write peers write entries, while get_agent_activity peers each query a single write agent's activity with get_agent_activity.

Before a target write peer and the requesting get_agent_activity peer are in sync, this will measure the get_agent_activity call performance over a network. Once a write peer reaches sync with a get_agent_activity peer, the write peer will publish their actions and entries, and so the get_agent_activity calls will likely have most of the data they need locally. At that point this measures the database query performance and code paths through host functions.

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.
