Logging Event Types

D3Renderer(port::Int, port_range::UnitRange; seek_store=nothing) -> D3Renderer

Constructs a D3Renderer, which is a TimespanLogging aggregator which renders the logs over HTTP using the d3.js library. port is the port that will be serving the HTTP website. port_range specifies a range of ports that will be used to listen for connections from other Dagger workers. seek_store, if specified, is a Tables.jl-compatible object that logs will be written to and read from. This table can be written to disk and then re-read later for offline log analysis.


LogWindow-compatible aggregator which stores logs in a Tables.jl-compatible sink.

Using a TableStorage is reasonably simple:

ml = TimespanLogging.MultiEventLog()

... # Add some events

lw = TimespanLogging.LogWindow(5*10^9, :core)

# Create a DataFrame with one Any[] for each event
df = DataFrame([key=>[] for key in keys(ml.consumers)]...)

# Create the TableStorage and register its creation handler
ts = DaggerWebDash.TableStorage(df)
push!(lw.creation_handlers, ts)

ml.aggregators[:lw] = lw

# Logs will now be saved into `df` automatically, and packages like
# DaggerWebDash.jl will automatically use it to retrieve subsets of the logs.
